Offre de thèse : Floral preferences of bumblebees across a range of European climates, Durham (UK)

Deadline: 7th January 2022Application: https://www.iapetus2.ac.uk/how-to-applyBackground:Bumblebees are agriculturally important pollinators, but are currently declining in abundance in the UK and around the world, in part due to climate change (Soroye et al. 2020). Understanding these declines requires research on the biology and ecology of these species. Bumblebees are thought to be generalists, pollinating a variety of flower species. However, our preliminary observations conducted in Durham in summers 2020 and 2021 indicate that different bumblebee species prefer different plants (see also Sikora et al. 2020). Bumblebees have been a preferred insect model for neuroethology and sensory neuroscience, and a wealth of earlier work has focussed on the importance of visual cues and nectar/pollen reward for foraging honeybees and bumblebees (Latty and Trueblood 2020). In contrast, the importance of floral smells is less well known, although some works report the essential role of flower volatiles in bumblebees’ floral choice (Galen and Kevan 1983; Suchet et al. 2011; Haber et al. 2019). This project will investigate olfactory preferences of commonly occurring bumblebees (e.g. Bombus terrestris, Bombus pascuorum and Bombus lapidarius) to naturally-occurring floral volatiles, and how these preferences are affected by climatic conditions and background plant communities in Norway (Kløfta), UK (Durham and Stirling), Germany (Würzburg), Italy (Milan) and Portugal (Braganca). We expect the plants that the bumblebees forage on to differ between these location, due to different climatic condition. We hypothesise that, despite the differences in plant species, the key components of floral bouquets will be very similar across test locations.Aims:1) To identify plants that bumblebees forage on in the five countries, to establish plant preferences for bumblebee species;2) Collect floral volatiles from the plants identified in Aim 1, as well as florals that bumblebees do not forage on, as controls; analyse these volatiles by GC/MS; 3) Establish behavioural preferences of bumblebees in response to full floral bouquets and components of bouquets, fractions and synthetic components of that are specific for focal plant species.Methodology:Bee and plant collections will be conducted in the areas around Durham, Stirling, Kløfta, Würzburg, Milan and Braganca in March-September during the local bumblebee foraging periods. The student will be advised and assisted during field collection by OR and local members of the supervisory team. Student will be trained to identify plants and bumblebees via morphological cues and DNA barcoding. Floral volatiles will be collected at the same time as bumblebees by using standard volatiles traps, and will be analysed by the student via gas chromatography-mass spectrometry in TS laboratory. Behavioural olfactory assays on bees will be conducted in the field or either in the glasshouse at the Biocentre, University of Würzburg or in a glasshouse at Durham Botanical garden. The bees will be given a choice between 2 stimuli, or stimulus and a control, and their preference for a smell will be inferred from the tendency of a bee to land at the stimulus.Training and skills:The student will receive training:1) by supervisors with complementary skills and expertise;2) by collaborators and postdocs in the seven participating institutions;3) by attending summer courses, conferences and Durham-run training events;4) by participating in regular public outreach activities;5) by helping OR to supervise UG students; 6) by presenting their work at lab meetings and conferences.The student will acquire knowledge and skills in:1) insect chemical ecology and neuroethology;2) gas chromatography/mass spectrometry and collection of volatiles;3) bumblebee rearing;4) identification of bumblebees and plants;5) molecular biology methods;6) cutting-edge techniques for behavioural analysis;7) presentation and scientific writing;8) research supervision;9) Impact and public outreach.Requirements:We are looking for an independent and enthusiastic student able to develop the project and drive it forward. Interest in sensory ecology, neuroethology, animal behaviour, chemical ecology and previous research experience are a plus.You should be available to conduct field and lab work in the UK and in continental Europe. The peak time for field work is in March – September.Further information:Informal enquiries are strongly encouraged and should be directed to Dr Lena Riabinina, olena.riabinina@durham.ac.uk, +44-191-334-1282Funding Notes:This project is in competition with others for funding. Students of any nationality may receive full funding. Success will depend on the quality of applications received, relative to those for competing projects.

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

Profil :

  • Etudiant de master ou école d’ingénieur (BAC +4 ou +5) en biologie/écologie/agro…
  • Compétences en SIG et utilisation de logiciel statistique (R)
  • Bases solides en écologie, entomologie et/ou botanique
  • Apte au travail de terrain
  • Sens de l’observation
  • Autonomie, rigueur et organisation

PhD postition in evolutionary biology, University of Lausanne

PhD position in social evolution, University of Lausanne

A Ph.D. position in evolutionary biology is available in the group of Prof. Michel Chapuisat at the Department of Ecology and Evolution, University of Lausanne, Switzerland. We are currently investigating the origin, evolution and mode of action of a supergene controlling social organization in ants. Our approach combines genomics, genetics, behavioral experiments and ecological surveys in the field. For more information, see http://www.unil.ch/dee/page7000.html.

Your responsibilities:
Animal societies vary greatly in social organization, yet the causes of this diversity are poorly understood. Ants belonging to the genus Formica provide an ideal system to study the underpinnings of social organization, because a supergene – a large group of linked genes – determines whether colonies have one or multiple queens. The successful candidate will perform experiments to better understand the genomic, behavioral or ecological processes leading to this social polymorphism. The project will provide insights into how supergenes evolve and how they generate biological diversity.

Your qualifications:
In order to complete our team, we are looking for someone with a Master’s degree in biology, life sciences, genetics, bioinformatics, or related subjects. Applicants should have knowledge and skills pertaining to evolutionary biology, genetics, genomics, behavior or ecology. We are looking for a creative, curious and motivated person with excellent communication and interpersonal skills.

What the position offers you:
We offer a nice working place in a multicultural, diverse and dynamic academic environment, with opportunities for professional training. The Department of Ecology and Evolution in Lausanne University hosts research groups working on a broad range of topics, producing a rich intellectual and social life. Although French is the common language in Lausanne region, the department research activities and seminars are conducted in English.

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.

2- Co-responsable : Alan Vergnes, Université Paul-Valéry, CEFE

Description du stage :

Contexte :
Les activités humaines ont fait entrer le monde dans une période de changements globaux où
l’on observe un déclin majeur des espèces. Les invasions biologiques sont un des facteurs
responsables de ce déclin (Bertelsmeier et al., 2016). En raison de leur rôle majeur dans le
fonctionnement des écosystèmes, les impacts des fourmis envahissantes sont souvent très
importants.
Le complexe taxonomique Tapinoma nigerrimum est un ensemble d’espèces de fourmis
vivant dans les sols. Une des « espèces » du complexe ; Tapinoma nigerrimum occupe des
habitats naturels ouverts dans la région méditerranéenne et construit des nids faiblement
peuplés, les autres Tapinoma darioi et Tapinoma magnum prospèrent dans les zones
urbanisées du sud de l’Europe comme dans la ville de Montpellier et forment des
supercolonies au caractère envahissant (Seifert et al., 2017 ; Centanni et al., in prep).

Objectifs :
Dans le cadre de la thèse de Julia Centanni, l’objectif du stage est d’étudier les conséquences
de la présence des fourmis T. darioi sur le reste de la myrmécofaune (communautés de
fourmis) au sein des espaces verts et en particulier des parcs de Montpellier.

Hypothèse :
On s’attend à observer un effet négatif sur la richesse spécifique lorsque T. darioi est présente.

Méthodologie :
La majeure partie du travail consistera à poser des pièges barber dans les parcs et espaces
verts urbains envahis ou non envahis de Montpellier, puis de procéder au tri des fourmis
récoltées et participer à l’identification de la myrmécofaune.

Pré-requis :
Goût pour le terrain et l’entomologie, minutie et patience seront nécessaires pour le tri, une
connaissance sur les fourmis serait appréciée.
Personne ayant le permis et véhiculée serait appréciée mais non indispensable.

Projet de maîtrise sur les fourmis du genre Leptothorax en forêt boréale mixte

Projet de maîtrise sur les fourmis du genre Leptothorax en forêt boréale mixte/
MSc opportunity on Leptothorax ants of the boreal mixedwoods.

Nous sommes à la recherche d’un(e) étudiant(e) pour un projet de maîtrise portant sur l’écologie des fourmis du genre Leptothorax en forêt boréale mixte.

Contexte et problématique
The present-day population biology of any given species is an outcome of the habitats that are available to it and the intrinsic and extrinsic factors that allow it to occupy those habitats. To understand a population of a species, we must understand how its habitats are generated and maintained, and how it colonizes and retains those habitats. These complex processes motivate efforts to identify and describe model ecosystems that possess enough complexity to exhibit general principles of population biology, but not so much complexity that they cannot be understood in detail.

As trees shed wood and decay, they produce nesting sites that ants can live in. Some ant species specialize on these sites, like coarse woody debris, and do not live in any other kind of habitat. Such sites provide an extrinsic limit to the size of an ant population, and are themselves an outcome of factors including the tree species composition, age, and past history of trees in a forest. The fraction of suitable nesting sites that are occupied by a given ant species is then an outcome of factors including the ability of ants to find and colonize new sites (dispersal), interactions with other species that exploit the same habitat (competition), and extrinsic mortality (predation).

In eastern Canada, Leptothoracine ants predominantly nest in coarse woody debris that is at a specific stage of decay (Lafleur et al. 2006). Within their particular debris type, this habitat is occupied by just two ant species: the small brown Leptothorax ergatogyneous, and the large black Leptothorax canadensis, and is not occupied by other free-living ants (Heinze 1993). L. ergatogyneous has a more restricted habitat range than L. canadensis, as it is additionally only found in habitats, such as roadsides and tree fall gaps, that possess an intermediate level of direct sunlight. Perhaps as a consequence of this specialization, L. ergatogyneous possesses an intraspecific genetic polymorphism between wingless queens (low dispersal; more prevalent in isolated habitat patches) and winged queens (high dispersal; more prevalent in continuous habitat) (Heinze & Buschinger 1989).

Finally, both L. ergatogyneous and L. canadensis are killed by a specialist parasite, the slave-making ant Harpagoxenus canadensis (Heinze et al. 1991; Stuart 2009). H. canadensis queens establish colonies by invading either L. canadensis or L. ergatogyneous colonies and killing the queen, and then maintain colonies by raiding worker pupae from neighboring L. canadensis and L. ergatogyneous colonies. Slave-making ants provide a particularly tractable model for predation in ants because, unlike other predators, they live within the colony they have killed. Thus, it is possible to estimate the extent of predation within a population by identifying a) the number of colonies occupied by H. canadensis queens, and b) the number of L. canadensis and L. ergatogyneous workers in those colonies.

Studies of Leptothoracine populations in eastern Canada therefore provide a) a manageably narrow and identifiable range of suitable habitat, b) competition for nesting sites between a specialist and a generalist species, c) discrete variation in dispersal capacity, and d) extrinsic mortality due to a specialized predator at a measurable rate.

A first step toward understanding this system would be to collect Leptothoracine ants in habitats that vary in ecologically-relevant conditions. These could differ in variables that contribute to habitat generation (tree species and demography, landscape features, recency of logging and burning), as well as habitat occupancy (habitat fragmentation, competition, and predation). Within a carefully-selected range habitats, the goal would be to perform standardized sampling of colonies to determine the number of colonies per species (L. ergatogyneous, L. canadensis, and H. canadensis), and score these colonies for the presence of winged versus wingless queens and the number and species of ants in the colony. Such a study would be scientifically valuable in its own right, and would motivate future research (ie, computational approaches like GIS and ecological niche modeling, and experimental methods like transplantation experiments).

Hommage à Christian Peeters

 

 

Chères et chers collègues,

C’est avec une grande tristesse que nous avons appris ce 1er septembre 2020 le décès de notre collègue et ami.

Christian était connu de tous comme un chercheur passionné par les fourmis, qu’il a étudiées tout au long de sa carrière, transmettant sa passion à de nombreux étudiants et au grand public via de nombreuses expositions et interventions médiatiques et culturelles.

En plus d’une très grande expertise naturaliste, Christian a su impulser de nouvelles réflexions passionnantes que ce soit sur la reproduction chez les fourmis sans reines, l’évolution de la caste reine et la fondation des colonies, ou plus récemment sur les évolutions morphologiques des ouvrières.

Globe trotter dans l’âme, il a parcouru le monde toute sa vie et rencontré nombre d’entre nous. Discuter avec Christian, de science ou de toute autre chose, était toujours un plaisir. Sa personnalité joviale et dynamique sera regrettée. Nos pensées vont à sa famille.

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.

Sexual signals in hermaphroditic worms and their evolution during the transition between hermaphroditism and separate sexes

 

Application deadline: May 31st 2020

Sexual selection is a central topic in behavioral ecology and is usually associated with male and female reproductive success. Communication between the two sexes is crucial at the moment of reproduction; a huge amount of research has focused on sexual signals, such as sexual pheromones, visual displays and bodily parades that males and females use in the context of mating. Although the majority of animals have separate sexes, hermaphroditism is almost ubiquitous among animal taxa and more than 65000 hermaphroditic species exist. Hermaphroditic organisms have the two sexual functions tied together in the same body, and produce female and male gametes either at the same time (simultaneous hermaphrodites), or at different times during their life (sequential hermaphrodites).

How does communication between sexes work in hermaphroditic species where individuals need to mate with partners to fertilize their eggs? What implications the hermaphroditic lifestyle has on signals and cues used to attract mates? What quality are hermaphrodites advertising to their partners? Given their two sexual functions, what information are hermaphrodites signaling to attract mates, and what sex are they advertising the most? At what extent do sexual signals produced by hermaphrodites convey honest information as opposed to manipulative substances to force partners into overexpressing the less preferred sex?

These questions have been rarely addressed in sexual selection research. This timely PhD project plans to meet these goals using the polychaete worms of the genus Ophryotrocha as biological models. This genus includes simultaneously and sequentially hermaphroditic species (all strictly unable to self), as well as species with separate sexes, making it possible to explore the evolution of sexual signals as sexual systems diversify.
