Offre de stage : Effet du gyrobroyage sur les communautés d’abeilles sauvages dans les ENS de l’Hérault

Effet du gyrobroyage sur les communautés d’abeilles sauvages dans les ENS de l’Hérault

Suite au désistement très récent de l’étudiant sélectionné, je suis à la recherche en urgence d’un(e) étudiant(e) de master (idéalement M2) sur ce thème. Merci de vos réponses rapides.

Contexte et problématique
La pollinisation connaît une crise mondiale, qui concerne à la fois les abeilles domestiques et sauvages, ainsi que l’ensemble des insectes pollinisateurs. Les problèmes de la filière apicole a permis de sensibiliser plus largement le grand public au déclin de l’ensemble des insectes pollinisateurs. Ce déclin pose problème à la fois du fait de la contribution notable de ces insectes pour la pollinisation des cultures agricoles, mais aussi en raison de leur rôle crucial pour la pollinisation en général et la conservation des espèces végétales sauvages. Les insectes pollinisateurs sauvages sont plus efficaces et contribuent plus largement à la pollinisation que la seule abeille domestique et le service écosystémique qu’ils rendent n’est pas compensable par la seule apiculture. La prise de conscience mondiale des insuffisances de pollinisation n’a qu’une quinzaine d’années, mais l’ampleur du problème et sa forte médiatisation expliquent la diffusion rapide et large de cette nouvelle préoccupation. Cette situation explique le contexte général, caractérisé par sa perception par le grand public, son appropriation par les ONG environnementales et la recherche scientifique autour des questions de pollinisation.
Á l’échelle du territoire français, c’est en 2016 que le Plan National d’Action (PNA) pour les pollinisateurs intitulé « France, terre de pollinisateurs » a été mis en place et porté par le ministère de l’environnement. Ce PNA établit clairement que les enjeux de la conservation des insectes pollinisateurs sont majeurs et qu’ils concernent à la fois la préservation de la biodiversité via les services indispensables aux équilibres écosystémiques, et la préservation de la diversité des ressources alimentaires des populations humaines. Ce PNA a également établi la liste de l’ensemble des connaissances à acquérir et à consolider pour agir efficacement, et insiste sur l’action nécessaire de formation et de sensibilisation ainsi que sur l’intérêt de proposer des actions de gestion et de conservation des pollinisateurs. A la suite de ce PNA (2016-2020), un nouveau plan pollinisateur a été mis en place et publié en novembre 2021, pour prendre effet en ce début d’année 2022 ; il est ceete fois co-porté par les ministères de l’environnement et de l’agriculture. Il est urgent de mieux connaitre les pollinisateurs, les facteurs influençant leur présence comme les ressources florales et l’efficacité des mesures de gestion menées en leur faveur.

Objectifs du stage
C’est dans ce contexte que le Département de l’Hérault a décidé de mettre en place des actions de gestion en faveur des insectes pollinisateurs et de soutenir des actions de recherche pour mieux comprendre les facteurs environnementaux favorisant leur présence. Ce département est situé en zone méditerranéenne et caractérisé par une diversité d’habitats allant des plages du littoral aux pelouses dolomitiques du Causse du Larzac en passant par les garrigues. Dans le cadre de sa politique de conservation des secteurs remarquables de son territoire, ce département a aussi la particularité d’avoir de nombreux Espaces Naturels Sensibles (ENS) et donc de pouvoir mener des actions de conservation en faveur de la biodiversité. Il est également marqué par une fermeture progressive du paysage, un embroussaillement menant au stade forestier du fait de l’exode rural d’après-guerre.
C’est pourquoi, une des principales mesures de gestion environnementale est le gyrobroyage de zones embroussaillées afin de réouvrir le milieu mais aussi le lutter localement contre les incendies. Cependant, l’impact de cette mesure de gestion sur les communautés d’abeilles sauvages reste mal connu, en particulier en zone méditerranéenne. Ce cadre local explique pourquoi l’objectif du stage de master proposé par le CEFE-CNRS sera de caractériser l’impact du gyrobroyage sur les communautés d’abeilles sauvages dans les ENS de l’Hérault. Cette caractérisation sera réalisée dans plusieurs ENS de l’Hérault par capture à la fois au filet et en pièges passifs à différents moments de l’année. Sur chacun de ces ENS, les communautés d’abeilles et la flore seraient comparées, en termes d’abondance et de diversité, entre un site gyrobroyé et un site témoin. De plus, chaque abeille sera associée à l’identification de la plante où elle a été capturée de façon à pouvoir construire le réseau d’interaction plantes-pollinisateurs, et à déterminer les caractères floraux et les facteurs environnementaux favorisant l’attraction des pollinisateurs. Grâce à une formation à l’identification des abeilles sauvages prévue en début du stage et suivie par le stagiaire, les abeilles capturées devront être préparées et identifiées au genre pour faciliter l’identification à l’espèce par un expert. Les futurs résultats seront publiables car ils amélioreront la connaissance des abeilles sauvages de ce département et auront des implications sur les futures mesures de gestion en faveur des insectes pollinisateurs.
Au vu des risques de confinement ou de contraintes liée à la crise sanitaire, un second sujet de programme de recherches est également proposé en respectant la thématique de l’étude des pollinisateurs de l’Hérault. Ce plan B concernerait « l’identification des caractères écologiques des abeilles sauvages inventoriées dans l’Hérault en vue de recommandation de gestion environnementale ». En effet, nous disposerons en février 2021 d’une base de données renseignant 60 caractères pour chacune des 975 espèces d’abeilles sauvages de France établie à dire d’expert. Ces caractères spécifiques présenteront par exemple les spécialisations alimentaires pour certaines espèces végétales, le mode de nidification, le nombre annuel de générations et la période de vol. Ces caractères spécifiques permettront d’établir une typologie des abeilles de l’Hérault, de prédire grossièrement les communautés d’espèces présentes par type d’habitat et donc d’établir des recommandations de gestion environnementale pour favoriser la présence de communautés complètes par habitat présents dans les ENS de l’Hérault.

Profil recherché
• Idéalement master 2, mais master 1 possible
• Intérêt pour la démarche scientifique et pour ses applications opérationnelles en conservation

Offre de thèse : NUTRIGENOMICS AND THE RESILIENCE OF BEES IN A CHANGING CLIMATE,

PhD: NUTRIGENOMICS AND THE RESILIENCE OF BEES IN A CHANGING CLIMATE, HULLDeadline for applications: 5 Jan 2022To apply, and for more details: https://panorama-dtp.ac.uk/research/nutrigenomics-and-the-resilience-of-bees-in-a-changing-climate/For details please contact Dr James Gilbert (james.gilbert@hull.ac.uk).Eligibility: UK, EU and International: see further info here: https://panorama-dtp.ac.uk/how-to-apply/Funding: UK (NERC, Competition-funded; CASE partner)A fully funded PhD position is now open for applications at the Universities of Hull and Leeds, UK, via NERC’s Panorama Doctoral Tranining Partnership programme.Bees, our foremost pollinators, are vital for ecosystem stability and global food security – providing pollination services worth hundreds of billions of pounds annually. The UK is home to ~245 species of wild bees which collectively perform more pollination than managed honeybees and bumblebees. Unfortunately, wild bee populations are declining, under pressure from multiple causes – one key factor being nutrition.All bees feed offspring with pollen gathered from the landscape. But human influences such as agricultural intensification are altering nutritional landscapes for bees [3,4], and fundamentally affecting gene expression, growth and reproduction. Most of what we know about bee nutrition comes from studies in social bees like honeybees or bumblebees [5,6], where nutrition influences caste determination, development, pathogen resistance and others. However, the nutritional ecology of other bees, particularly solitary bees, is largely unstudied.Human activity is also changing climates and raising average temperatures. Temperature affects animals’ metabolic rate, physiology, digestion, and nutrient assimilation, as well as gene expression. Dr Gilbert’s recent work [7] has identified the need to store enough carbohydrate and fat to survive the winter as potentially critical for solitary bees’ nutritional ecology. But we know little about how this is regulated, how climate change will affect bees, and how bees will deal with changing nutritional landscapes in a future filled with uncertainty.We are now, for the first time, in a position to understand not just whether but also how different nutritional landscapes and climates affect bees. This exciting cross-institutional project combines field ecology with cutting edge molecular approaches to address a crucial knowledge gap about how bees are being affected by human-altered nutritional landscapes. This project addresses issues relevant for pure ecological science, conservation biology, agriculture and crop science.At Hull, Dr Gilbert’s lab has pioneered rearing protocols for the economically and ecologically important solitary bee, Osmia bicornis. This work is providing an unprecedented window onto bee nutritional ecology. At Leeds, Dr Duncan’s lab uses a variety of cutting-edge molecular tools to understand how bees are influenced by their environment. Dr Duncan has conducted groundbreaking work on how nutrition affects gene expression in developing bees, as well as recent work on the environmental and molecular control of reproduction in O. bicornis. The student will capitalise on this timely opportunity to synthesize the research interests of these two research groups and create collaborative links between institutions. The candidate will be integrated into both lab groups and will benefit from the infrastructure and connections at both universities.Using careful manipulations within controlled laboratory environments, the student will first establish how dietary macronutrients affect the fitness of solitary bee larvae in response to changes in rearing temperature. Then, they will use high-throughput sequencing technology to examine genome-wide expression profiles of larvae receiving different diet and temperature treatments, to understand the molecular and physiological mechanisms underlying bees’ responses to landscape and climate change. Nutritional cues are known to alter gene expression [8], but to date studies have focussed largely on a few genes, and only in honeybees. The student will compare larvae receiving different treatments in (1) choices larvae make about which nutrients to consume, (2) correlates of fitness such as body size and overwinter survival, and (3) expression of growth- versus diapause-related genes.Outcomes: The findings will, firstly, shed light on the optimal nutrition for bees – both currently, and in a warmer future. They will help inform active measures such as wildflower strips to conserve and promote these vital pollinators as the climate changes. Secondly, results will also show the physiological effects of different nutritional landscapes upon bees, now and in the future, allowing us a detailed understanding of the resilience of solitary bees to landscape change in a changing climate. Finally, the results will provide comparisons and contrasts with existing knowledge of social bee gene expression, physiology and nutrigenomics, providing unparalleled insights into bee nutritional ecology.References: 1.

Résumé du poste

Le/La post-doctorant(e) contribuera à la réalisation d’un projet de recherche BeeFeeDISporté par l’UMR 5174 EDBde l’Université de Toulouse et financé par le programme PREMATURATION Région OCCITANIE/SATT. Ce projet est intitulé : « Biocontrôle du principal parasite de l’abeille, Varroa destructor: perturbation de deux signaux nécessaires à sa fonction de nourrissage».

 

Position dans l’organisation

Le/La post-doctorant(e), recruté(e) pour dix huit mois à partir du 1erfévrier 2022, mènera ses activités dans le cadre de l’UMR EDB de l’Université de Toulouse sur les deux sites, toulousain et albigeois, sous la direction d’Angélique Vétillard, MCF HDR et porteur du projet, et sera accompagné dans ses fonctions par Philipp Heeb, DR CNRS.

 

Contexte général du sujet

Avec plus de 35 000 tonnes de miel et ses dérivés importés contre 20 000 tonnes produites en 2017, la France se place parmi les plus gros consommateurs de miel au monde. Même si la production de miel tend à augmenter au fil des années, à l’instar de l’Occitanie qui détient 22% des ruches en France et se place à la première place des régions apicoles de France (France Agrimer 2018), de grandes menaces pèsent sur les ruchers français. Depuis plusieurs années, la filière apicole est confrontée à une mortalité accrue et à un affaiblissement des colonies d’abeilles domestiques. Un des principaux responsablesde cet hécatombe est l’acarien Varroa destructor, parasite vecteur de nombreux virus létaux pour les abeilles. Il n’y a actuellement aucun moyen de lutte efficace contre cette espèce compatible avec une apiculture biologique respectueuse de l’environnement. Le projet BeeFeeDIS pose les bases d’un nouveau concept de lutte par biocontrôle afin de réduire l’impact de ce fléau sur les colonies d’abeilles.

Dans ce contexte, le laboratoire a identifié deux kairomones hémolymphatiques de l’abeille stimulatrices de la prise alimentaire de Varroaqui pourraient, à terme, être exploiter pour mettre au point un système de lutte sur la base d’une confusion parasitaire.

 

Profil et missions

Le/La post-doctorant(e) sélectionné(e) devra être titulaire d’une thèse en biochimie analytique ou écologie chimique. Ses missions consisteront, en collaboration avec l’équipe, à déterminer la caractérisation structurale de deux nouvelles kairomones ainsi qu’à étudier les effets directs de ces deux-sémio-chimiques kairomonaux sur la prise alimentaire de Varroa. L’objectif est l’obtention d’une primo-formule à base de ces deux composés olfactifs utilisée en lutte biologique sur la base d’une confusion parasitaire. Le/la candidat(e) retenu(e) sera capable de travailler en équipe, fera preuve d’une grande rigueur scientifique et d’un grand sens de l’organisation.

 

Pas d’allergie déclarée aux piqûres d’hyménoptères.

Modelling honeybee colony resilience from field data – a 2-year postdoc position

  

Working places: Unité Mixte de Recherche EGCE – Evolution, Génomes, Comportement et Écologie – Gif-sur-Yvette – France (IRD, CNRS, Univ. Paris-Saclay; www.egce.cnrs-gif.fr), and fieldwork in several French study sites.

 Job description: We open a 2-year postdoc position related to the ongoing H2020 BeeConnected project (details here). The postdoc main objective is to study the resilience of honey bee colonies (Apis mellifera) along gradients in climate and landscape complexity. To reach that objective, the postdoc will benefit from a large and original dataset of honey bee colony dynamics collected through an automatic standardized monitoring over multiple European countries. The postdoc will explore spatio-temporal trends in the in-hive behaviour of honey bee colonies in order (i) to assess the effects of stress events (e.g. swarming, food shortage, queen failure) on the colony dynamic, (ii) to analyse the colony ability to recover from stress events (exploring potential climate×landscape dependent effects) and (iii) to define endpoints in the colony resilience.

 Targeted profile: The postdoc requires a strong technical expertise in bioinformatics for scientific data analysis with experience in R and/or Python and good modelling practices. Knowledge in evolutionary ecology and life history traits with a PhD and/or a postdoc in those areas are welcome. Further requirements are knowledge in spatio-temporal dynamics of complex biological systems, proficiency in writing and communication skills, self-motivation, and ability to work in an international and interdisciplinary team. Good knowledge in French and English is required.

 Conditions: The postdoc will integrate the UMR EGCE based in Gif-sur-Yvette (southwest of Paris, France, in the green valley of Chevreuse). Project meeting are planned in Europe. Salary and benefits are according to public service positions in France, depending on experience. The postdoc start date is planned on February 2022.

 Application procedures: Send your application in a single pdf file by email to Fabrice Requier (fabrice.requier@egce.cnrs-gif.fr) and François Rebaudo (francois.rebaudo@ird.fr) no later than November 30th, 2021.

Offre de stage : Etude des réseaux d’interactions plantes-pollinisateurs dans les agro-écosystèmes (Polynésie française)

Ce stage s’inscrit dans le cadre des activités du 11è FED régional du Pacifique, dont le thème est la transition agro-écologique et le développement de l’agriculture biologique dans les PTOM. Les systèmes de production agricole polynésiens évoluent et la Direction de l’agriculture de Polynésie française (DAG), dont l’une des missions est de favoriser le développement économique de l’agriculture en contribuant au renforcement des capacités de production durable, souhaite accompagner cette conversion vers une gestion durable des agro-écosystèmes.
Actuellement, la Polynésie française compte quelques 570 apiculteurs répartis sur 48 îles dans les 5 archipels, possédant un total de 13 400 ruches, pour une production annuelle de miel estimée à 200 tonnes en 2019. Une étude de 2016, commandée par le service de l’agriculture polynésien et réalisée par le GNS Science International de Nouvelle Zélande, a permis de mettre en évidence le potentiel d’expansion de l’apiculture locale à travers une meilleure connaissance des ressources mellifères des différents archipels.

La connaissance des plantes mellifères présentes dans les différents milieux participe notamment à :L’orientation du choix d’emplacement des ruchers ;
Une meilleure conduite apicole (anticipation des miellées et du calendrier de travail, bonne gestion du nourrissement, etc) ;
La valorisation de la diversité de miels issue de ce patrimoine naturel riche.
Par ailleurs, la durabilité de filières végétales des PTOM, notamment la coprahculture et le maraîchage, est tributaire des pollinisateurs.

Or, si l’abeille dite « domestique » (Apis mellifera) est devenue emblématique de la pollinisation, il existe à l’échelle mondiale pas moins de 20.000 espèces d’abeilles sauvages et bien d’autres espèces animales qui participent à ce service écosystémique indispensable. À ce jour, les données sur la présence de ces espèces et leurs interactions avec les espèces végétales en Polynésie française sont très peu nombreuses. Or ces données sont indispensables dans la détermination de mesures favorisant le service de pollinisation, mais aussi pour favoriser une apiculture plus résiliente et respectueuse des écosystèmes naturels à travers une implantation raisonnée des ruchers.
Le stage vise à augmenter les connaissances sur les réseaux de pollinisation dans les agro-écosystèmes du Pacifique Sud, en particulier de Polynésie française. Il contribuera également à poursuivre l’inventaire de la flore mellifère et à acquérir des connaissances pour une meilleure évaluation du potentiel mellifère des paysages.

Missions et activités en 3 volets :
1. Une revue bibliographique et la mise au point de protocoles d’étude adaptés ;
2. La mise en oeuvre des protocoles et le suivi des expérimentations in situ ;
3. Le transfert et la diffusion des résultats auprès de différents publics (apiculteurs/agriculteurs, administrations, associations, étudiants, privés…).

Forte Importance des Déplacements et du travail de terrain entre différents archipels (pris en charge par le stage)

Durée stage: 6 mois – à partir septembre 2021

Offre de stage de Master 2 à Lille : Exposition des abeilles sauvages aux polluants urbains

Titre du sujet : Exposition des abeilles sauvages aux polluants urbains : imprégnations individuelles et caractérisation des sources de contamination

 

Bref descriptif :

Le succès des pollinisateurs sauvages en ville, réel en zones suburbaines, apparait plus limité en zones à fort taux d’urbanisation. Dans ces zones, l’exposition accrue aux polluants urbains pourrait être l’une des causes des déclins observés, par le biais d’effets négatifs sur la santé individuelle et sur les interactions mutualistes que ces insectes entretiennent avec les plantes qu’ils pollinisent. Présents dans de nombreux produits de consommation courante, les phtalates sont des composés organiques semi-volatiles que l’on retrouve couramment dans l’air intérieur des bâtiments et résidences, d’où ils contaminent l’air extérieur à des taux compatibles avec des effets biologiques observés chez des hyménoptères (réduction de la fertilité ; inflammation). Nous émettons l’hypothèse que les phtalates, s’ils s’avèrent plus présents en zones très urbanisées, pourraient affecter la santé des pollinisateurs sauvages vivant en milieu urbain.

Le but de ce stage sera de déterminer les taux d’imprégnation cuticulaire de deux espèces témoins d’abeilles sauvages (Bombus terrestis et B. pascuorum) selon un gradient d’urbanisation au sein de la métropole de Lille. Il s’agira de comparer la nature et les taux de phtalates détectés sur les insectes, avec ceux relevés dans l’air ambiant des différents sites d’étude (analyses par GC-MS), et de croiser ces données avec les cartographies physiques des sites à notre disposition. Les questions à investiguer seront les suivantes : les taux de phtalates dans l’air ambiant augmentent-ils avec le taux d’urbanisation ? l’imprégnation cuticulaire des bourdons est-elle corrélée aux taux dans l’air ambiant ? Les taux relevés dans l’air et sur les insectes sont-ils prédictibles selon les types et densités de sources potentielles à proximité (bâtiments d’habitation, de commerce…) ? Nous évaluerons également les taux de contamination des pollens de plantes attractrices présentes sur les différents sites afin de déterminer si ces nourritures collectées par les bourdons pourraient être source de contamination pour eux.

Le stage se déroulera de mars à aout 2021, inclus.

Offre de Post-doc (30 mois) : INRAE Abeilles et Environnement (Avignon)

Bees & Environment, INRAE Avignon, France

In a rapidly changing environment, honeybee colonies are increasingly exposed to diverse sources of stress, which represent a challenge to their social homeostasis and can ultimately lead to their collapse. A multifactorial aetiology has often been reported (e.g. new parasites, decline in flower availability/diversity and exposure to agrochemicals acting in isolation or in combination). However, the manner in which stressors affect honeybee colonies and contribute to losses is poorly understood, which leads to major gaps in the environmental risk assessment of stressors and the implementation of effective policy and management responses. The underlying mechanisms remain unclear due to the complex nature of the potential combinations of stressors, but also to the difficulty of assessing the honeybee colony state in a robust manner in ever-changing environmental conditions. Notably, in the field and on a case-by-case basis, it remains difficult for beekeepers or surveillance networks to identify stressors or detect critical losses of bees and potential risks of colony decline since hives are visited at discrete times and the notion of temporal evolution of colonies is often lacking. In addition, identifying the drivers that shape colony development requires high-resolution data.

In this context, the development of tools to develop real-time and automatic recording of different colony parameters is a promising approach. Within the EU-project B-GOOD (Giving beekeeping guidance by computational-assisted decision-making, https://b-good-project.eu/), several tools are being used to monitor colonies and build a European database. The postdoc candidate will use this database to integrate data obtained from hive sensors to colony dynamic, identify the most useful parameters for predicting context-dependent colony health, and establish the relationship between environmental, biological and management drivers and bee health status. The ultimate goal will be to develop a modelling framework identifying abnormal colony events.  The candidate will be strongly involved in statistical analysis and modelling to characterize temporal processes (such as number of honeybees in colonies, weight of colonies, bee traffic, carbon dioxide and temperature regulation… ) in order to identify normal and abnormal events or change of these processes over time. This task will require intensive and efficient computing. Thus, the candidate is expected to have advanced experience in computer programming, statistics, temporal statistics and simulations with a high proficiency in R.

The postdoc will join the “Bees and Environment” research unit (AE, Avignon), which develop a wide range of research programs that are targeted to the study of honeybee and wild bee populations, in the context of sustainable farming and food security. The activity of the unit is organized around understanding the factors that are responsible for honeybee colony losses and the worldwide decline in wild bee populations, and the impact of this decline on biodiversity and crop production.  The postdoc will work in close collaboration with the Biostatistics and Spatial Processes research unit (BioSP, Avignon), which carries out research in mathematics and statistics, with applications in epidemiology, ecology and environmental sciences. AE and BioSP have been involved together in numerous research and operational projects.
Funding
The position is funded for 30 months by the EU-project B-GOOD

Offre de stage : sweat bee, Halictus rubicundus

 

We are seeking field assistants to help with research social behaviour in the ground nesting sweat bee, Halictus rubicundus for periods of between 2 and 5 months. This could be early April to early June, or late June to late August, or both combined. Start and end dates can be negotiated to some extent within these constraints, but the successful candidate/s must be available for the entire period agreed.

The assistant will be working alongside a Postdoctoral researcher at the Knepp rewilding estate in Sussex, UK. H. rubicundus is a medium sized bee that nests in small colonies (fewer than 10 individuals) in the ground and has an insignificant sting.

Work will involve:

observing foraging behaviour, handling and marking bees, setting up video cameras, uploading video footage and excavating nests from the ground. In warm weather, field assistants will work long days in the field; in bad weather there will be tasks to carry out back at the accommodation/opportunity for time off. Because the work involves recording colour marks on individual animals, the job would not be suitable for someone who is colour-blind. See our research group website for more information about the kind of work we do (https://biosciences.exeter.ac.uk/staff/index.php?web_id=Jeremy_Field).

 

Experience of working with insects and a Degree (or working towards a Degree) in a Behaviour/Evolution/Ecology-related topic are desired. The successful applicants must have enthusiasm for fieldwork and be prepared to work hard. They will obtain excellent experience of cutting-edge social insect research.

Shared accommodation near Knepp is provided, but assistants are required to pay for their own food/personal expenses. Assistants receive £125 per week to cover costs. At the time of applying, candidates must be able to demonstrate that they have the right to work in the UK.

 

Please contact Dr Rebecca Boulton (r.boulton@exeter.ac.uk) and CC Prof. Jeremy Field (j.p.Field@exeter.ac.uk) to discuss these positions further.

CONTEXTE DU STAGE

Ce stage intervient dans le cadre du projet EI2P « Espèces invasives et pollinisateurs, entre contraintes et potentiels », financé par la Région Occitanie. Les invasions biologiques et le déclin des populations d’abeilles sont deux phénomènes qui représentent des défis majeurs car ils ont un impact négatif sur les activités économiques et agricoles et contribuent à la vulnérabilité des populations humaines. Au-delà du discours prônant une éradication irréaliste et sans nuances, ce projet explore la complexité des questions liées à la perception, à la dynamique spatiale, à la gestion et à l’utilisation potentielle des espèces exotiques envahissantes dans un contexte d’acteurs multiples aux intérêts divergents, grâce à une approche interdisciplinaire associant sciences humaines, sciences spatiales et sciences naturelles. Ce projet vise à contribuer à une meilleure compréhension des impacts des espèces envahissantes sur les systèmes de production, de leurs conséquences possibles sur les services écosystémiques, de leurs potentiels – notamment pour l’apiculture – et de leur prise en compte dans les représentations des acteurs par une approche holistique. Ce stage s’inscrit dans le volet « éthologie » du projet, qui s’attache en particulier à mettre en évidence la façon dont les abeilles perçoivent certaines espèces exotiques envahissantes dans les Pyrénées.

 

RENSEIGNEMENTS SUR LE SUJET

Objectif :

Analyser si les espèces florales invasives présentent des traits sensoriels particuliers qui leur confèrent un avantage dans un contexte de détection et butinage par les pollinisateurs, en particulier par l’abeille domestique Apis mellifera.

 

Description :

Nous nous focaliserons sur deux espèces florales invasives paradigmatiques, Reynouatria japonica (renouée du Japon) et Impatiens glandulifera (balsamine de l’Himalaya) et sur un pollinisateur majoritaire et généraliste, l’abeille domestique Apis mellifera. La connaissance approfondie des systèmes sensoriels et du traitement de ces signaux par les circuits cérébraux de l’abeille permet de comprendre et de caractériser la saillance perceptuelle des signaux floraux pour les abeilles. Ainsi, nous serons en mesure de comprendre comment les espèces invasives sont perçues par les abeilles et si elles présentent des avantages sensoriels par rapport aux espèces locales qui les entourent.

 

Dans un premier temps, nous effectuerons sur le terrain des mesures florales afin de déterminer les spectres de réflection spectrale des espèces citées ci-dessus et des espèces locales adjacentes. Nous essaierons aussi d’obtenir des échantillons des fragrances florales des espèces invasives afin de déterminer par la suite si les odeurs impliquées sont particulièrement bien apprises par les abeilles. Finalement, au niveau gustatif, nous analyserons les caractéristiques du nectar présent dans les fleurs afin de le comparer à celui des fleurs locales.

 

Dans un deuxième temps, nous réaliserons des expériences d’apprentissage dans le laboratoire afin de déterminer si les abeilles préfèrent et/ou apprennent de façon avantageuse les informations sensorielles (en particulier les odeurs) des espèces invasives.

 

A la fin, nous serons donc en mesure de 1) caractériser la sensorialité de deux espèces invasives paradigmatiques sur différents domaines perceptuels des abeilles, et 2) déterminer leur efficacité dans des expériences d’apprentissage et mémorisation, capacités qui sont à la base des activités de butinage de ces insectes.

 

 

Profil requis :

Bac +5, compétences en environnement et/ou éthologie.

 

Qualités : motivation et rigueur, sachant travailler en équipe, aimant les contacts et l’interdisciplinarité, bonnes capacités rédactionnelles et organisationnelles.

 

Date du stage : Ce stage, d’une durée de 5 mois, sera réalisé entre mai et septembre 2020 (dates ajustables).

 

Indemnités : le/la stagiaire sera indemnisé(e) sur la base de la législation en vigueur + prise en charge des frais de déplacement

 

Lieu : Toulouse, et terrain dans les Pyrénées

Offre de thèse : Thermal Adaptation in Native Australian Bees, Monash

No deadline given

Monash U Australia/Graduate Position/Immediate start

A fully-funded Ph.D. position is available examining thermal adaptation in native Australian bees. Bees are keystone species in many ecosystems due to their role as pollinators. Any changes in the abundance and distribution of bees will have significant knock-on effects on biodiversity and ecosystem services. Despite their outsized ecological role, we know very little about climatic adaptation in bees, or even which climatic factors drive bee distributions.

In this project, we will use the rich and diverse Australian bee fauna to investigate the capacity of bees to adapt to climate change. Using field-based surveys of a bees thermal tolerances, comparative phylogenetic approaches and field reciprocal transplant experiments the project aims to: determine the role of temperature and rainfall in shaping the distribution of native bee species, predict the capacity of native bees to adapt to climate change and determine the role of environment and genetic variation in shaping population variation.

We are seeking a student who is highly motivated and passionate about evolutionary biology. Preferred candidates will have experience in evolution, ecology and thermal physiology, although experience in these areas is not necessary. There will be opportunities for the successful applicant to pursue their own scientific ideas within the aims of the project. The successful candidates will be supervised by Dr Vanessa Kellermann (Monash University) and Dr Ros Gloag (University of Sydney) and will be based at Monash University’s School of Biological Sciences.

The successful applicant will be awarded a scholarship that covers salary (current rate is $27,862 AUD tax-free per year), and a waiver of student fees, international students are welcome to apply.

Interested applicants should submit a CV, a copy of their academic transcript and a cover letter outlining their research interests to vanessa.kellermann@monash.edu and ros.gloag@sydney.edu.au. For links to the PhD application process at Monash University go to vanessakellermann.com.

 GRADUATE POSITION:BEE GENOMICS, HULL
   
    Ecosystem stability and global food security depend upon healthy populations of bees, our foremost pollinators. Bees provide pollination services worth hundreds of billions of pounds annually. Honeybees and bumblebees are our most important managed pollinators, but the UK is home to ~245 species of wild solitary bees which collectively perform most pollination.
   
    Unfortunately, bee populations are declining, with multiple causes. Key to bee survival and fitness is nutrition; all bees feed offspring with pollen gathered from the landscape. But human influences such as agricultural intensification are altering nutritional landscapes for bees [3,4], and fundamentally affecting gene expression, growth and reproduction. Most of what we know about bee nutrition comes from studies in social bees like honeybees or bumblebees [5,6], where nutrition influences caste determination, development, pathogen resistance and others. However, the nutritional ecology of other bees, particularly solitary bees, is largely unstudied. Unless these bees can detect and respond to changes in nutritional landscapes, their fitness will be reduced « V a scenario we term a « nutritional trap ».
   
    Human activity is also changing climates and raising average temperatures. Temperature affects animals’ metabolic rate, physiology, digestion, and nutrient assimilation, as well as gene expression. Dr Gilbert’s recent work [7] has identified the need to store enough carbohydrate and fat to survive the winter as potentially critical for solitary bees’ nutritional ecology. But we know little about how this is regulated, how climate change will affect bees, and how bees will deal with changing nutritional landscapes in a future filled with uncertainty.
   
    We are now, for the first time, in a position to understand not just whether but also how different nutritional landscapes and climates affect bees. This exciting cross-institutional project combines field ecology with cutting edge molecular approaches to address a crucial knowledge gap about how bees are being affected by human-altered nutritional landscapes. This project addresses issues relevant for pure ecological science, conservation biology, agriculture and crop science. At Hull, Dr Gilbert »¦s lab has pioneered rearing protocols for the economically and ecologically important solitary bee, Osmia bicornis. This work is providing an unprecedented window onto bee nutritional ecology. At Leeds, Dr Duncan »¦s lab uses a variety of cutting-edge molecular tools to understand how bees are influenced by their environment. Dr Duncan has conducted groundbreaking work on how nutrition affects gene expression in developing bees, as well as recent work on the environmental and molecular control of reproduction in O. bicornis. The student will capitalise on this timely opportunity to synthesize the research interests of these two research groups and create collaborative links between institutions. The candidate will be integrated into both lab groups and will benefit from the infrastructure and connections at both universities.
   
    Differences in larval nutrition in the honeybee results in gene expression changes and ultimately adult bees with different reproductive potential and lifespan. Using careful manipulations within controlled laboratory environments, the student will first establish how dietary macronutrients affect the fitness of solitary bee larvae in response to changes in rearing temperature. Then, they will use high-throughput sequencing technology to examine genome-wide expression profiles of larvae receiving different diet and temperature treatments, to understand the molecular and physiological mechanisms underlying bees »¦ responses to landscape and climate change. Nutritional cues are known to alter gene expression [8], but to date studies have focussed largely on a few genes, and only in honeybees. The student will compare larvae receiving different treatments in (1) choices larvae make about which nutrients to consume, (2) correlates of fitness such as body size and overwinter survival, and (3) expression of growth- versus diapause-related genes. Outcomes: The findings will, firstly, shed light on the optimal nutrition for bees « V both currently, and in a warmer future. They will help inform active measures such as wildflower strips to conserve and promote these vital pollinators as the climate changes. Secondly, results will also show the physiological effects of different nutritional landscapes upon bees, now and in the future, allowing us a detailed understanding of the resilience of solitary bees to landscape change in a changing climate. Finally, the results will provide comparisons and contrasts with existing knowledge of social bee gene expression, physiology and nutrigenomics, providing unparalleled insights into bee nutritional ecology.

 2 PhD STUDENTSHIPS: THE ECOLOGY OF BEES ON A CHANGING PLANET, IMPERIAL COLLEGE LONDON
   
    1. CONTEXT DEPENDENCE OF DISEASE SPREAD AND VIRULENCE IN A POLLINATOR SYSTEM
    Supervisors: Peter Graystock, Sophie Evison & Richard Gill (secured funding)
    Deadline 13 January 2020
   
    In host-parasite coevolution, the Red Queen hypothesis states that the contest between host and parasite drives continuous adaptation to counter the ever-evolving opposition. Understanding this dynamic is made more complex when external forces intervene to change the environment, particularly anthropogenic activities and the rates at which they occur. The Melissococcus plutonius bacteria is known to be common in honey bees, often without influencing host health. However, unknown triggers can cause this bacteria to express a harmful and often deadly disease known as European foul brood (EFB). This globally distributed disease causes significant damage to the beekeeping industry, and in the UK, EFB is one of only two microbial bee diseases considered so harmful that positive detection requires immediate notification to the authorities. Yet despite the impact of this disease, we currently have little understanding as to what stressors influence the severity and spread of this disease, and if human practices such as land-use change or pesticide application could be influencing the delicate host-parasite interaction.
   
    The student will explore the mechanism behind transmission of the causal bacteria of the disease (Melissococcus plutonius), before determining if key stressors (Land and pesticide use) influence the severity of the disease. This directly-funded studentship will employ a suite of cutting-edge scientific techniques to address questions on what modulates the transmission and virulence of this disease. The project will add substantially to our understanding of the vulnerability of bees to this significantly destructive disease and the results will facilitate the formation of evidence-led disease management strategies. The student will gain a set of interdisciplinary skills including field work, next generation DNA sequencing and bioinformatics, pesticide residue analysis, microbiology and honeybee keeping. The student will gain training and collaboration from leading scientists including supervisor Dr Peter Graystock (Imperial College London), Dr Richard Gill (Imperial College London), and Dr Sophie Evison (University of Nottingham), plus assistance from the National Bee Unit/Defra.

    2. ARCTICBUZZ: STUDYING POPULATION DYNAMICS TO UNDERSTAND THE EVOLUTION OF PLANT-POLLINATOR NETWORKS UNDER CLIMATE CHANGE
    Supervisors: Richard Gill, Jacob Johansson & Keith Larson (competitively funded)
    Deadline 6 January 2020
   
    To date our understanding of how insect pollinator declines are influenced by climate change remains limited. For instance, why have some species shown evidence of latitudinal range shifts in apparent response to climate change when others have not? To address this type of question requires us to understand the eco-evolutionary processes by which insect pollinator populations and their host plants are dynamically responding and how this translates to long term changes in the structure of plant-pollinator networks under climate change. Taking a population biology approach, this project will look to understand how bumblebee populations and host plant visitations have changed over the past 50 years for an Arctic bumblebee community in Lapland, Sweden. This will involve understanding how preceding climatic condition has affected population demography of each of 13 species of bumblebee. The study will reveal changes on population trait frequencies over space and time and how resource competition is determined through adaptations to temperature extremes to predict plant-pollinator network structure and the potential for species invasions. Looking at intra- and interannual population and community turnover of the bumblebees and their host plants we will look to inform predictive models under warming scenarios and identify early warning signs of climate change impacts. Furthermore, this project will reveal the spatio-temporal variation (non-static) in the bumblebee-plant visitation network to reveal how resistant and resilient the mutualistic interaction network is to climate change.
   
    The project takes advantage of a unique phenology transect established over a century ago allowing us to compare past data on bumblebee/plant community composition and phenology with contemporary data spanning the major warming over the last five decades. The transect runs along an altitudinal gradient on Mount Nuolja, Abisko, providing a thermal cline with the study taking a space-for-time substitution approach. The student will become experienced in using a number of interdisciplinary techniques, including a variety of fieldwork skills, bee and plant taxonomic identification, molecular methods in DNA barcoding and population genetics, studying bee thermal profiling, managing and analysing big data, skills in ecological network construction, statistics and developing mathematical models to understand extinction vulnerability. The project will involve a significant amount of fieldwork in the Arctic and will require the candidate to be relatively physically fit. This interdisciplinary project will also benefit from co-supervision & collaboration from a number of world-leading scientists, including: Jacob Johansson (Imperial College and Lund University, Sweden); Keith Larson (Umea University, Sweden); Jason Tylianakis (Canterbury University, NZ), Andrew MacDougal (University of Guelph, Canada); Emily Baird (Stockholm University (Sweden).

    For further information, please contact Mairi Knight: mairi.knight@plymouth.ac.uk
   
    Background:
    Many pollinator species, recognised as essential for ecosystem function, are undergoing rapid declines. One recent exception is the ‘Tree Bumblebee’ Bombus hypnorum: expanding its range into and across the UK in <20 years, it is now one of our most common species.
   
    Building on previous work from the supervisory team, and in collaboration with the Earlham Institute, this project will investigate key genomic differences between this and other bumblebee (Bombus) species to substantially improve our understanding of the factors contributing to its success, along with the declines of others. The project’s focus is a genomic comparison of Bombus species from within the UK and continental Europe. Initial work has identified genomic regions of interest in B. hypnorum that may be indicative of its ability to adapt to anthropogenically altered landscapes. However, current data are preliminary and lack essential phylogenetic comparison.
   
    Methodology:
    This is a timely and exciting opportunity to generate a highly novel, and substantial, genomic dataset to test hypotheses as to whether the observed genomic differences are unique to B. hypnorum, or shared among Bombus species (some evidence suggests elevated resilience in the wider Pyrobombus sub-genus). In addition to fulfilling the specific aims, the data generated will offer the student significant scope to guide the project’s further direction through characterisation of genomic signatures and differences across this important pollinator group.
   
    Training
    The project will equip the successful student with state-of-the-art genomic techniques as well as bioinformatic and modelling skills that are highly transferable and increasingly essential across a wide range of academic and applied biological disciplines. The student will also gain important soft skills (e.g. communication, team working, problem solving). He/she will be based in Plymouth, spending short periods at the other Institutions as relevant.
   
    Person Specification
    The successful candidate will have a biology-based degree, an academic interest in evolutionary ecology, and be enthusiastic about pursuing a laboratory- and computer-based project. Ideally, he/she will have some basic molecular ecology experience (e.g. DNA extraction, PCR) and interest in genetic and evolutionary analysis. Experience of genome sequencing and bioinformatics is not essential as full training will be provided.

 PhD: ANTS AS ECOSYSTEM ENGINEERS, YORK
   
    PhD: Ants as ecosystem engineers: the interaction between niche construction and land management, University of York, UK
   
    We are looking for an enthusiastic and ambitious student to develop a novel project that will use applied field experiments to quantify the relationship between meadow ants and management regimes, and how these together
    affect biodiversity and soil function. The ideal candidate will enjoy interacting with academics and stakeholders from a range of backgrounds and want to apply their scientific training to an important applied question.
   
    Ants act as effective geoengineers, increasing habitat heterogeneity and constructing niches. Yellow meadow ants, Lasius flavus, were historically common on pastures. These ants promote biodiversity, for example they
    increase floral species richness because the ant mound soil differs from surrounding areas. Many modern farming practices reduce or eliminate their populations.
   
    Belton House, a National Trust property including 650 hectares of historic (Grade 1 Registered) wood pasture parkland, which is a UK priority habitat, has areas hosting an unusually high density of meadow ants, but also other areas where they are entirely absent. Previous management of the site has resulted in some areas suffering from over-grazing and soil compaction. The study site is undergoing a period of management change, to a more biodiversity-friendly approach of mixed and lighter grazing. Despite the known importance of ants within the soil ecosystems, very little is known about how the ecosystem impacts of meadow ants are mediated, and how these impacts interact with past and present pasture management practices. The collaboration with CASE partner The National Trust provides the opportunity to carry out controlled experiments, altering management to assess impact on ant populations, and altering ant populations to assess impact on ecosystem composition and function.
   
    This project will be supervised by Elva Robinson (ant behavioural ecologist, University of York), Kelly Redeker (soil biogeochemist, University of York) and Carl Hawke (Nature Conservation Advisor, The National Trust). This is a NERC ACCE DTP studentship. Eligibility: UK/EU applicants only.

Offre de thèse : University of Konstanz, Germany

A fully funded position is available to study the social regulation of stinging behaviour of honeybees. Honeybees defend their nest against large predators thanks to a collective effort to harass and sting the intruder. The stinger apparatus has evolved to detach upon stinging elastic skin (such as ours) to maximize venom delivery, but the drawback is that the mutilated bee then dies within a few hours. Thus, the colony under threat must achieve a delicate balance: enough bees need to respond that the intruder is successfully deterred, but without unnecessarily depleting the colony of its workforce. The aim of this project is to understand how this balance is reached. In particular, it focuses on how each individual bee takes the decision to attack or not, depending on the social information that it receives. We aim for an integrative approach, ranging from behavioural experiments and modelling to neuroanatomy and pharmacology.

Offre de stage : Effet du gradient de fermeture du milieu sur les communautés d’abeilles sauvages dans les ENS de l’Hérault (34)

Contexte et problématique
La pollinisation connait une crise mondiale, qui concerne à la fois les abeilles domestiques et sauvages, ainsi que l’ensemble des insectes pollinisateurs. Les problèmes de la filière apicole a permis de sensibiliser plus largement le grand public au déclin de l’ensemble des insectes pollinisateurs. Ce déclin pose problème à la fois du fait de la contribution notable de ces insectes pour la pollinisation des cultures agricoles, mais aussi en raison de leur rôle crucial pour la pollinisation en général et la conservation des espèces végétales sauvages. Les insectes pollinisateurs sauvages sont plus efficaces et contribuent plus largement à la pollinisation que la seule abeille domestique et le service écosystémique qu’ils rendent n’est pas compensable par la seule apiculture. La prise de conscience mondiale des insuffisances de pollinisation n’a qu’une quinzaine d’années, mais l’ampleur du problème et sa forte médiatisation expliquent la diffusion rapide et large de cette nouvelle préoccupation. Cette situation explique le contexte général, caractérisé par sa perception par le grand public, son appropriation par les ONG environnementales et la recherche scientifique autour des questions de pollinisation.
Á l’échelle du territoire français, il n’existe pas d’études de ce déclin sur l’ensemble des pollinisateurs ; cependant, il existe plusieurs indices d’un déclin similaire des pollinisateurs (bourdons, papillons…), surtout dans les zones d’agriculture intensive. C’est en 2016 que le MEED (Ministère de l’Environnement, de l’Énergie et de la Mer) a mis en place un Plan National d’Action (PNA) pour les pollinisateurs intitulé « France, terre de pollinisateurs ». Ce PNA établit clairement que les enjeux de la conservation des insectes pollinisateurs sont majeurs et qu’ils concernent à la fois 1) la préservation de la biodiversité via les services indispensables aux équilibres écosystémiques, et 2) la préservation de la diversité des ressources alimentaires des populations humaines. Ce PNA a également établi la liste de l’ensemble des connaissances à acquérir et à consolider pour agir efficacement, et insiste sur l’action nécessaire de formation et de sensibilisation ainsi que sur l’intérêt de proposer des actions de gestion et de conservation des pollinisateurs. Il est donc urgent de mieux connaitre les pollinisateurs, les facteurs influençant leur présence comme les ressources florales et l’efficacité des mesures de gestion menées en leur faveur.

Objectifs du stage
C’est dans ce contexte que le département de l’Hérault a décidé de mettre en place des actions de gestion en faveur des insectes pollinisateurs et de soutenir des actions de recherche pour mieux comprendre les facteurs environnementaux favorisant leur présence. Ce département est situé en zone méditerranéenne et caractérisé par une diversité d’habitats allant des plages du littoral aux pelouses dolomitiques du Causse du Larzac en passant par les garrigues. Ce département est aussi marqué par une fermeture progressive du paysage par un embroussaillement menant au stade forestier du fait de l’exode rural d’après-guerre. Cependant, l’impact de cette fermeture du paysage sur les communautés d’abeilles sauvages reste mal connu, en particulier en zone méditerranéenne. Dans le cadre de sa politique de conservation des secteurs remarquables de son territoire, ce département a aussi la particularité d’avoir de nombreux Espaces Naturels Sensibles (ENS) et donc de pouvoir mener des actions de conservation en faveur de la biodiversité.
Ce cadre local explique pourquoi l’objectif de ce stage de master sera de caractériser les communautés d’abeilles sauvages le long de gradient de fermeture du paysage, en distinguant des stades herbacés, arbustifs et forestiers. Cette caractérisation sera réalisée dans trois ENS de l’Hérault par capture à la fois au filet et en pièges passifs à différents moments de l’année. Il est envisagé de tester trois types de gradients selon l’espèce forestière dominante, avec surement une forêt de chêne blanc, une de chêne vert et une de résineux (pin d’Alep ou pin noir). De plus, chaque abeille sera associée à l’identification de la plante où elle a été capturée de façon à pouvoir construire le réseau d’interaction plantes-pollinisateurs, et à déterminer les caractères floraux (nectar, morphologie, couleur, odeur…) et les facteurs environnementaux favorisant l’attraction des pollinisateurs. Grâce à une formation à l’identification des abeilles sauvages prévue en début du stage, les abeilles capturées devront être préparées et identifiées au genre pour faciliter l’identification à l’espèce par un expert. Les futurs résultats seront publiables car ils amélioreront la connaissance des abeilles sauvages de ce département et auront des implications sur les futures mesures de gestion en faveur des insectes pollinisateurs.

• Master 2
• Intérêt pour la démarche scientifique et pour ses applications opérationnelles en conservation
• Intérêt pour les relations plantes-insectes

https://panorama-dtp.ac.uk/research/nutrigenomics-and-the-resilience-of-bees-in-a-changing-climate/

Deadline: 6 Jan 2020

Eligibility: UK and EU students only

Funding: UK (NERC, Competition-funded)

 

Ecosystem stability and global food security depend upon healthy populations of bees, our foremost pollinators. Bees provide pollination services worth hundreds of billions of pounds annually. Honeybees and bumblebees are our most important managed pollinators, but the UK is home to ~245 species of wild solitary bees which collectively perform most pollination.

 

Unfortunately, bee populations are declining, with multiple causes. Key to bee survival and fitness is nutrition; all bees feed offspring with pollen gathered from the landscape. But human influences such as agricultural intensification are altering nutritional landscapes for bees [3,4], and fundamentally affecting gene expression, growth and reproduction. Most of what we know about bee nutrition comes from studies in social bees like honeybees or bumblebees [5,6], where nutrition influences caste determination, development, pathogen resistance and others. However, the nutritional ecology of other bees, particularly solitary bees, is largely unstudied. Unless these bees can detect and respond to changes in nutritional landscapes, their fitness will be reduced ¡V a scenario we term a ¡§nutritional trap¡¨.

 

Human activity is also changing climates and raising average temperatures. Temperature affects animals¡¦ metabolic rate, physiology, digestion, and nutrient assimilation, as well as gene expression. Dr Gilbert¡¦s recent work [7] has identified the need to store enough carbohydrate and fat to survive the winter as potentially critical for solitary bees¡¦ nutritional ecology. But we know little about how this is regulated, how climate change will affect bees, and how bees will deal with changing nutritional landscapes in a future filled with uncertainty.

 

We are now, for the first time, in a position to understand not just whether but also how different nutritional landscapes and climates affect bees. This exciting cross-institutional project combines field ecology with cutting edge molecular approaches to address a crucial knowledge gap about how bees are being affected by human-altered nutritional landscapes. This project addresses issues relevant for pure ecological science, conservation biology, agriculture and crop science.  At Hull, Dr Gilbert¡¦s lab has pioneered rearing protocols for the economically and ecologically important solitary bee, Osmia bicornis. This work is providing an unprecedented window onto bee nutritional ecology. At Leeds, Dr Duncan¡¦s lab uses a variety of cutting-edge molecular tools to understand how bees are influenced by their environment. Dr Duncan has conducted groundbreaking work on how nutrition affects gene expression in developing bees, as well as recent work on the environmental and molecular control of reproduction in O. bicornis. The student will capitalise on this timely opportunity to synthesize the research interests of these two research groups and create collaborative links between institutions. The candidate will be integrated into both lab groups and will benefit from the infrastructure and connections at both universities.

 

Differences in larval nutrition in the honeybee results in gene expression changes and ultimately adult bees with different reproductive potential and lifespan. Using careful manipulations within controlled laboratory environments, the student will first establish how dietary macronutrients affect the fitness of solitary bee larvae in response to changes in rearing temperature. Then, they will use high-throughput sequencing technology to examine genome-wide expression profiles of larvae receiving different diet and temperature treatments, to understand the molecular and physiological mechanisms underlying bees¡¦ responses to landscape and climate change. Nutritional cues are known to alter gene expression [8], but to date, studies have focussed largely on a few genes, and only in honeybees. The student will compare larvae receiving different treatments in (1) choices larvae make about which nutrients to consume,

(2) correlates of fitness such as body size and overwinter survival, and (3) expression of growth- versus diapause-related genes.  Outcomes:

The findings will, firstly, shed light on the optimal nutrition for bees ¡V both currently, and in a warmer future. They will help inform active measures such as wildflower strips to conserve and promote these vital pollinators as the climate changes. Secondly, results will also show the physiological effects of different nutritional landscapes upon bees, now and in the future, allowing us a detailed understanding of the resilience of solitary bees to landscape change in a changing climate. Finally, the results will provide comparisons and contrast with existing knowledge of social bee gene expression, physiology and nutrigenomics, providing unparalleled insights into bee nutritional ecology.

Offres thèse et Stage M2 : Pollinator health & bee abundance, Virginia tech

POLLINATOR HEALTH & BEE ABUNDANCE, VIRGINIA TECH

 

The Couvillon Lab and the O’Rourke Lab, both at Virginia Tech, seek 2 (1 Ph.D., 1 M.S./Ph.D.) highly motivated students with a keen interest in pollinator health & native bee abundance and diversity to join our research groups. Students will begin in Fall 2020 or Winter 2021.

 

The Ph.D. student will be under the main supervision of Dr. Margaret Couvillon, Assistant Professor of Pollinator Biology and Ecology in the Department of Entomology, and co-advised by Dr. Megan O’Rourke, Associate Professor in the School of Plant and Environmental Sciences. The M.S./Ph.D. student will be under the main supervision of Dr. O’Rourke and co-advised by Dr. Couvillon.

 

Available positions: One Ph.D. (4 years) and one M.S./Ph.D. (2 or 4 years) positions studying the survival, fitness, and performance of native and wild bees and pollinator communities and their abundance and diversity across different landscapes. Students should have a keen interest in native bee abundance and diversity and pollinator health in general.

 

* Expertise and/or interest in bee taxonomy and identification would be extremely helpful.

 

Application deadline: 1 DECEMBER, 2019, with video interviews in January 2020 and a decision in early February 2020.

 

Start date: Preferably Fall 2020 for Ph.D. student and Winter 2021 for M.S. student, but this is open to some negotiation.

 

Background: Lack of forage is a factor contributing to bee declines. This stressor can act directly, where hungry bees are unable to meet their nutritional needs, or indirectly, where the resulting nutritional stress reduces the bees’ ability to cope with other stressors like diseases and pesticides. Media coverage has been wide, and as a consequence, everyone wants to feed hungry bees. Such help is offered with best intentions, but efficacy is undermined by two crucial knowledge gaps: firstly, we do not fully understand the foraging dynamics of bees across diverse landscapes because the current methods of surveying, cataloging, and comparing floral abundance at a landscape-scale is intensely time-consuming. Secondly, nutritional stress is often studied either in honey bees (Apis mellifera spp.) or non-honey bees, creating a dichotomy that limits the usefulness of resulting recommendations. Thus, there is a critical need to develop new methods to survey forage on a landscape scale and whether a good landscape for feeding one type of bee is also a good landscape for feeding other bees. Only with such data may we implement a best management strategy for improving food availability to benefit overall pollinator health in a meaningful, targeted way.

 

These new studentships are part of a larger, 5 year ongoing project funded by FFAR (Foundation for Food and Agricultural Research), with Lead PI Couvillon and co-PIs O’Rourke, Taylor, and Schurch, all at Virginia Tech.

 

Potential applied and basic science projects may include these questions:

– What landscape characteristics are most associated with overall pollinator health?

– How does pollinator community diversity and abundance vary with landscapes?

– How does stressor exposure, such as to pesticides, affect abundance, diversity, and health of non-Apis bees?

– What plant communities are associated with landscapes that support diverse and abundant pollinator communities?

– How do honey bee foraging dynamics, as determined by previous work, relate to the abundance, diversity, and health of non-Apis bees? In other words, are honey bees good bioindicators for native and wild bee pollinators?

 

M.S. requirements:

– BS in Biology, Entomology, Landscape Ecology or related STEM field

– Fulfillment of requirements set out by the Department of Entomology at Virginia Tech and The School of Plant and Environmental Sciences

– An excitement for working with live, whole organisms (that sting!)

– A willingness to learn new skills, such as experimental design, scientific reproducibility, statistics, GIS, and insect identification

– Proficiency in English and excellent verbal and written communication skills

– A collaborative, helpful, team-oriented spirit

 

Additional Ph.D. requirements:

– An MS in Biology, Entomology, Landscape Ecology, or related STEM field or significant research experience, preferably with peer reviewed publications.

– Fulfillment of requirements set out by the Department of Entomology at Virginia Tech and The School of Plant and Environmental Sciences
