Résumé (in english below)

La communication est à la base de toutes les interactions sociales dans la nature. La diversification des échanges d’informations, est une étape clé dans l’évolution de la socialité. Chez les insectes eusociaux, l’organisation sociale nécessite une grande pluralité de signaux, transmis par différents canaux de communication (chimique, vibroacoustique, visuel ou tactile). Chez ces espèces, la régulation de la division des taches reproductrices est primordiale, et généralement contrôlée par un faible nombre d’individus dans les colonies. De nombreuses études se sont intéressées aux signaux chimiques volatiles, mais d’autres voies de communications pourraient être davantage efficace dans certains environnements. Chez les espèces souterraines, comme par exemple les termites du genre Reticulitermes, la communication vibratoire est omniprésente. Des composés chimiques peu volatile, déposés sur le substrat ou transmis par contact entre les membres de la colonie, peuvent aussi être efficace dans les environnement clos comme les galeries souterraines. Cependant, leur implication dans l’organisation sociale et plus particulièrement dans la régulation des tâches reproductrices reste peu explorée. Au cours de cette thèse, je me suis intéressé à ce manque d’information, en étudiant ces voies de communications chez le termite à pattes jaunes Reticulitermes flavipes. J’ai d’abord étudié le comportement d’exploration d’une propagule (petit groupe d’individu) de termites R. flavipes en le comparant à d’autres espèces/populations du genre Reticulitermes. Puis je me suis intéressé au rôle des signaux reproducteurs dans la différenciation des castes. Plus particulièrement j’ai étudié le rôle des vibrations produites par un comportement observé en présence d’individus reproducteurs : le body-shaking, mais aussi le rôle des composés cuticulaires hydrophiles des reproducteurs. Enfin, j’ai décrit la structure physique des vibrations produites lors du comportement de body-shaking et testé leur implication dans l’organisation sociale d’une propagule de termite.

Grace au développement d’un système de mesure laser, de play-back des vibrations et de tracking vidéo automatisé à l’échelle individuelle, j’ai pu mesurer, caractériser et étudier l’impact des vibrations sur l’organisation sociale de R. flavipes. Mes résultats montrent tout d’abord que le comportement d’exploration d’une propagule varie selon les espèces, en lien avec leur organisation sociale. Les vibrations émises lors du comportement vibratoire de body-shaking sont impliqués dans la régulation de l’accès à la reproduction. En effet, en présence de ces vibrations, la proportion d’ouvriers se différenciants en reproducteur diminue, alors qu’en présence des vibrations contrôles, le nombre de reproducteurs augmente. Il s’avère que les vibrations émises durant le comportement de body-shaking ont une structure particulière, composés de différentes parties avec des fréquences variables. De plus, cette structure est affectée par la présence de reproducteurs. Lors d’expériences de playback des vibrations, les vibrations rejouées affectent l’occurrence et le nombre d’individu produisant le comportement de body-shaking (body-shaker). A courte échelle de temps, il semblerait que la production de ce comportement ne soit pas spécifique à certains individus. Étonnamment, ces body-shakers ont néanmoins une activité plus importante avec, notamment une distance parcourue plus grande comparé aux non-body-shakers.
Dans son ensemble, ce travail de thèse apporte de nouveau éléments concernant la régulation de l’organisation sociale chez les insectes eusociaux, et plus spécifiquement sur la division des tâches reproductrices au seins des colonies de termite. Il amène à de nouvelles perspectives de recherche sur l’importante de certains canaux de communication moins étudiés, et sur l’implication de signaux sociaux transmis par ses derniers dans la régulation de l’organisation sociale.

Abstract

Communication is a central component of all social interactions in nature. The diversification of information exchange is a key step in the evolution of sociality. In eusocial insects, social organisation requires a high plurality of signals, transmitted through several communication channels (chemical, vibro-acoustic, visual or tactile). The regulation of the division of reproductive tasks is essential and is generally controlled by a very small number of individuals in the colonies. Many studies have focused on volatile chemical signals, but other communication channels may be more effective in certain environments. In subterranean species, such as termites of the genus Reticulitermes, vibratory communication is ubiquitous. Low volatile chemical compounds, deposited on the substrate or transmitted by contact between colony members, may also be effective in closed environments such as underground galleries. However, their implication in social organisation and especially in the regulation of reproductive division of labour remains poorly explored. In this thesis, I addressed this information gap by studying these communication channels in the subterranean termite species Reticulitermes flavipes. I first investigated the exploration behaviour of a propagule (small group of individuals) of R. flavipes termites in comparison with other species/populations of the genus Reticulitermes. Then I studied the role of reproductive signals in reproductives differentiation. I focused on the role of the vibrations produced by a behaviour observed in the presence of reproductives: the body-shaking, as well as on the role of the cuticular polar compounds of reproductives in the differentiation. Finally, I described the physical structure of the vibrations produced during body-shaking behaviour and tested their implication in the social and spatial organisation of a termite propagule.

Thanks to the development of a laser measurement, vibration playback and automated video tracking system at the individual scale, I was able to measure, characterize and study the impact of vibrations on the social organization of R. flavipes. My results show firstly that the exploration behaviour of a propagule varies between species, in relation to their social organization. The vibrations emitted by the body-shaking behaviour are involved in the regulation of reproductive access. Indeed, in the presence of these vibrations the proportion of workers differentiated as reproductives decrease, whereas in presence of the control vibrations the number of reproductives increase. It turns out that the vibrations emitted during body-shaking behaviour have a particular structure, consisting of different parts with varying frequencies. Moreover, this structure is affected by the presence of reproductives. During vibration play-back experiments, the replayed vibrations affect the occurrence and number of individuals producing the body-shaking behaviour (body-shaker). On a short time scale, it seems that the production of this behaviour is not individual specific. Surprisingly, the body-shakers present nevertheless a greater activity, with for example a greater distance walked compared to non-body-shakers.
This thesis work provides new elements concerning the regulation of social organisation in eusocial insects, and more specifically on the division of reproductive tasks within termite colonies. It leads to new research perspectives on the importance of some communication channels that are less studied, and on the implication of social signals transmitted by those channels in the regulation of social organisation.

Offre de Post-doc : Ecotoxicologie / écologie chimique du bourdons terrestre (Bombus terrestris)

Offre de Post-doc – Ecotoxicologie / écologie chimique du bourdons terrestre (Bombus terrestris)

Contexte
Les pollinisateurs sont soumis à des pressions multiples dont les importances relatives, dans le cadre de leur déclin généralisé, sont encore mal connues. Parmi elles, l’exposition aux polluants chimiques d’origine anthropique pourrait contribuer significativement à ce déclin, par toxicité directe ou par induction d’effets sub-létaux. En zone urbaine, les pollinisateurs peuvent échapper aux insecticides grâce aux politiques zérophyto mais restent soumis à de nombreux autres polluants atmosphériques émis dans ces zones de haute densité humaine. Des travaux récents ont montré que, grâce aux mesures anti-pollution adoptées en Europe et aux États-Unis, l’exposition aux aérosols carbonés d’origine fossile y concerne de moins en moins les sources liées aux transports et de plus en plus les produits chimiques volatils issus notamment des revêtements, des encres d’imprimerie, des adhésifs, des produits de nettoyage et de soins personnels. Parmi ces composés volatils, les phtalates sont susceptibles d’affecter négativement la santé et les performances des pollinisateurs, de par leur nature lipophile qui les fait traverser aisément les cuticules des insectes, et de par leurs effets de perturbateurs endocriniens, avérés chez plusieurs modèles de vertébrés et d’invertébrés, qui les rends susceptibles de déréguler des grandes fonctions telles que la reproduction ou l’immunité. Chez les insectes, certains phtalates pourraient également, en dérégulant les voies contrôlées par les ecdystéroïdes, affecter l’olfaction. Au cours de ce contrat de recherche, il s’agira de tester cette hypothèse.
Ainsi, dans le cadre du projet ASPI (Abeilles sauvages en ville : effets des polluants urbains sur la santé des insectes et sur les interactions plantes – pollinisateurs) financé par l’ANSES, nous recherchons une personne motivée pour investiguer les conséquences de l’exposition à certains phtalates, seuls ou en mélanges, sur la réponse sensorielle du bourdon terrestre aux composés organiques volatils biogéniques (COVBs) émis par les ressources florales (mesurée par électro-antennographie), ainsi que ses aptitudes cognitives et mémorielles.

Titulaire d’un doctorat en écotoxicologue, en neuroscience ou écologie chimique, le/la candidat(e) devra avoir de l’expérience en matière de manipulation des insectes. Être formé(e) à la mise en place de tests comportementaux et/ou à l’électro-antennographie sur insecte sera apprécié.

Durée : 12 mois
Rémunération : 2500€ brut/mois
Quand : idéalement, prise de fonctions à la mi-janvier 2023
Où : Le poste découle d’une collaboration entre le laboratoire EEP (UMR8198, Lille) et le CEFE (UMR5175, Montpellier) ; la personne sera recrutée au sein du laboratoire EEP, sous la supervision de Virginie Cuvillier, mais l’essentiel des manipulations se feront à Montpellier, sous la direction de Magali Proffit.

Merci d’envoyer un CV, une lettre de motivation et les coordonnées de deux référents, conjointement à virginie.cuvillier@univ-lille.fr et magali.proffit@cefe.cnrs.fr.
La date limite pour répondre à cette offre de recrutement est fixée au 13 Novembre 2022. Pour les candidats retenus des auditions seront organisées entre le 28 Novembre et le 2 décembre.

Post-Doc position – Ecotoxicology / chemical ecology of terrestrial bumblebees (Bombus terrestris)

Context
Pollinators endure multiple pressures, the relative importance of which is still poorly known, in the context of their general decline. Among them, exposure to anthropic chemical pollutants could contribute significantly to this decline, by direct toxicity or by induction of sublethal effects. In urban areas, pollinators may escape insecticides thanks to zero-phyto policies but are still subject to the many other air pollutants emitted in these areas of high human density. Recent work has shown that thanks to the pollution control measures enacted in Europe and the USA, exposure to carbonaceous aerosols of fossil origin in urban areas is transitioning away from transportation-related sources and toward volatile chemical products, including coatings, printing inks, adhesives, cleaning agents, and personal care products. Among these volatile compounds, phthalates may negatively affect the health and fitness of pollinators, crossing easily the insect cuticle due to their lipophilic nature and disturbing important functions such as reproduction and immunity, in accordance with their properties of endocrine disruptors proved in several vertebrate and invertebrate models. In insects, some phthalates could also disrupt olfaction by dysregulating the pathways that are under the control of ecdysteroids. We want to test this hypothesis during this research contract. Thus, as part of the ASPI project (Wild bees in the city: effects of urban pollutants on insect health and plant-pollinator interactions) funded by ANSES, we are looking for a motivated person to investigate the consequences of exposure to some phthalates, alone or in mixtures, on the sensory response of the terrestrial bumblebee to biogenic volatile organic compounds (VOCBs) emitted by floral resources (measured by electro-antennography), as well as its cognitive and memory abilities.

Candidates must hold a PhD in ecotoxicology, neuroscience, or chemical ecology, and have skills in insect handling. Training in the implementation of behavioral tests and/or electro-antennography on insects will be appreciated.

How long? 12 months
Salary: Gross salary is approximately 2500 €/month
When? Ideally, from January 2023
Where? The position results from a collaboration between the EEP laboratory (UMR8198, Lille) and the CEFE (UMR5175, Montpellier); the person will be recruited within the EEP laboratory, under the supervision of Virginie Cuvillier, but most of the manipulations will be done in Montpellier, under the direction of Magali Proffit.

Please send a detailed CV, a cover letter stating your previous research experience and motivation, and the contact details of two academic references, both to virginie.cuvillier@univ-lille.fr and magali.proffit@cefe.cnrs.fr.

Applications are accepted until November 13th, 2022. For successful candidates, auditions will be organized between November 28th and December 2nd.

A Postdoctoral position is available in the group of Prof. Michel Chapuisat at the Department of Ecology and Evolution, University of Lausanne, Switzerland. The group studies social evolution. We are currently investigating the origin, evolution, and mechanisms of action of a supergene controlling social organization across Formica ants (see http://www.unil.ch/dee/page7000.html). Recent research showed that some species have three supergene haplotypes. F. selysi and F. cinerea commonly hybridize, raising the possibility of supergene introgression. The postdoctoral researcher will generate and analyse population genomics data to uncover key processes governing supergene evolution, including selection, genetic load, drive and introgression. This project will shed light on how supergenes arise, spread and shape complex alternative phenotypes.

Your responsibilities:
You will study the evolution of a social supergene. This will involve field sampling of multiple ant species, population analyses (e.g. sex-ratio, male production), sequencing, population genomic, comparative genomic, and phylogenomic analyses. Depending on your personal interests and skills, projects on genome evolution, molecular evolution, behavioural genetics and ecological genomics are also possible.

Your qualifications:
We are seeking to recruit an early carrier post-doctoral researcher with a PhD degree in evolutionary biology, genetics, genomics, bioinformatics or related fields. The ideal candidate should have skills and experience in one or more of the following fields: population biology, population genetics, comparative genomics, phylogenetics, ecological genomics, molecular evolution. The candidate should have a convincing publication track-record, excellent inter-personal skills and a strong ability to work in a team.

Offre de Post-doc : Evolution of a kin recognition system in social insects at the University of Bristol

The role

We are seeking an experienced and energetic postdoc to work on our Leverhulme Trust Research Project ‘Evolution of a kin recognition system in social insects’. How do altruistic individuals recognise social parasites? In some bees, wasps and ants most individuals forgo reproduction to support the offspring of others. This evolutionary conundrum is explained by kin selection, where helping related individuals indirectly promotes the helper’s overall fitness. However, this strategy is vulnerable to exploitation. An ability to distinguish kin from non-kin is therefore critical for social living to evolve. By combining broad taxonomic sampling with detailed neuroanatomical, genomic and functional characterisation of the sensory structures underpinning kin recognition, we are investigating the neural and chemosensory adaptations that support this behaviour, and the remarkable diversity of Hymenopteran social systems.

What will you be doing?

This role will lead the genomics side of this project, working together with other team members in the UK and France. The work will include collating published genomic data across Hymenoptera, and combining it with newly sequenced genomes to perform phylogenetic analyses of chemoreceptor genes. These analyses will be informed, and combined, with data on neuroanatomical traits.

 

You should apply if

The role will suit someone with experience in handling large genomic datasets, genome assembly, annotation and phylogenetic analyses, and excellent data handling and organizational skills. You will be working with a multidisciplinary team, so must have strong communication skills and an enthusiasm for understanding different branches of biology.

For informal enquiries please contact Dr Stephen Montgomery (s.montgomery@bristol.ac.uk).

We welcome applications from all members of our community and are particularly encouraging those from diverse groups, such as members of the LGBT+ and BAME communities, to join us.
Closing date :  05 Apr 2022
Salary :  £34,304 – £38,587 per annum

4-year PhD studentship for international students  – apply by April 28th 2022 23:59 GMT

A fully funded 4-year PhD studentship for international students available in the research group of Dr Nathalie Stroeymeyt in the School of Biological Sciences, University of Bristol, to study the effect of temporal activity cycles on disease transmission dynamics in ant colonies.

Background

Group living offers favourable conditions for the spread of infectious diseases, because high population densities and frequent social contacts facilitate pathogen transmission. To mitigate that risk, social animals have evolved a variety of defence mechanisms to prevent the entry and propagation of pathogens within the group, ranging from a raised investment in personal immunity to highly coordinated collective sanitary actions (‘social immunity’). Recent studies have shown that social groups can also adopt organizational features, such as the subdivision into well-separated subgroups, which reduce epidemic risk through transmission bottleneck effects. However, the importance of organizational immunity features in disease risk management by real animal groups is still poorly understood. Our research adopts an empirical approach based on the experimental manipulations of garden ant colonies (Lasius niger) to (i) quantify the effect of social organization on disease transmission and test key predictions from network epidemiology, and (ii) evaluate the relative of importance of personal immunity, collective sanitary actions and organizational features under different environmental conditions and at different stages of development (for more detail see https://stroeymeyt-lab.co.uk/research).

The project

Whilst recent experimental work has highlighted the importance of spatio-social organisation in shaping interaction networks and determining epidemic risks in ants [1], the prediction that temporal heterogeneities in activity should also have a strong impact on disease transmission within social groups has received very little attention [2, 3]. This PhD project will aim to use experimental manipulations to investigate the effect of short-term temporal activity cycles on transmission dynamics in ants. Using an automated behavioural tracking system [1, 3], the candidate will quantify short-term activity cycles within Leptothorax acervorum ant colonies and design reliable methods to manipulate these activity cycles (e.g. either disrupt them, accelerate them or slow them down). These methods will then be used to carry-out fully-controlled experiment testing the effect of experimental manipulations of the colony’s activity cycles on the transmission dynamics of both pathogenic and non-pathogenic agents through the colony. This project should provide the first formal empirical test of whether coordinated bursts of activity within a social group slows down the propagation of disease through ant colonies, and whether activity synchronization may be used as a strategy to fight diseases.

Desired profile

We are looking for candidates with a background in animal behaviour and/or computational biology, and an eagerness to learn and apply a variety of approaches (behavioural tracking, writing own code to analyse data, lab work). Candidates should be creative and motivated, have good oral and written communication skills, and be at ease working both independently and as part of a team. Candidates must be eligible for ‘home’ fee status in the UK.

The position

The position will be part of an overall project team consisting of three PhD students and three post-doctoral researchers and will be fully funded for four years (stipend + overseas tuition fees + bench fees) by the University of Bristol. Only international students that do not qualify for home fee status may apply.

Expected starting date

September 2022.

How to apply

If you are interested in applying, please get in contact with Dr Nathalie Stroeymeyt (nathalie.stroeymeyt@bristol.ac.uk) and consult the official add on FindAPhD (click here). Formal applications should be submitted on the online application portal (click here) by Friday April 28th 2022 23:59 GMT.

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
• Intérêt pour les relations plantes-insectes notamment de pollinisation
• Connaissance de la flore méditerranéenne et intérêt pour les abeilles sauvages

Offres de thèse (x2) : ANT POPULATION GENOMICS & SOCIAL SUPERGENE DRIVE

UNIVERSITY OF LAUSANNEApplication deadlines: 15 January 2022 and 1 February 2022 (Incoming applications will continue to be considered until the positions are filled)Two Ph.D. positions (graduate assistants) in evolutionary biology are available in the group of Prof. Michel Chapuisat at the Department of Ecology and Evolution, University of Lausanne, Switzerland. The successful candidates will join a group studying the evolution and genomic basis of social organization in ants (see http://www.unil.ch/dee/page7000.html).1) THE EVOLUTION OF SUPERCOLONIALITYThe objective of the Ph.D. will be to investigate the evolution of supercoloniality in ants of the genus Formica. In the Swiss Jura mountains, the native wood ant Formica paralugubris forms large supercolonies, with hundreds of nests connected by trails and hundreds of queens in each nest. The evolution of such supercolonies is still poorly understood. High-throughput sequencing and population genomic analyses will provide high-resolution information on population structure, dispersal patterns, symbionts, and genomic basis of colony traits such as sex ratio. Comparative analyses will reveal if the supergene controlling polymorphic social organization in other Formica species has been fixed or lost in F. paralugubris, and if the same genes and alleles are associated with high colony queen number across the genus.Your responsibilities:You will develop research on the evolution of ant sociality and supercoloniality. This will involve field sampling, sequencing, population genomic and comparative genomic analyses. Depending on your interests and skills, behavioural and ecological experiments are also possible.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, population genetics, molecular evolution and/or behavioural ecology. We are looking for a creative and driven person with excellent interpersonal skills.Job information:Expected start date in position: 01.03.2022 (or at earliest convenience)Contract length: The initial contract is for 1 year, renewable twice for two years, up to a maximum of 5 years in totalActivity rate: 85%Workplace: Lausanne – DorignyWhat 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. The working language in the group and in the Department is English for all scientific matters. Good command of English is needed, some knowledge of French would be a plus, but is not mandatory. The University of Lausanne offers state-of-the-art facilities, including excellent computer facilities and molecular labs.Contact for further information:Prof. Michel Chapuisat : Michel.Chapuisat@unil.chYour application:Deadline: 15.01.2022Incoming applications will continue to be considered until the position is filled.To apply, please upload a single pdf document containing: a cover letter with a short description of your research interests, research experience, and why you are interested in joining our group; Your CV; The contact details of 2-3 referees; A copy of your Master degree; Your Master’s thesis summary.To receive full consideration, application documents should be uploaded online through the University of Lausanne recruitment platform. Please apply through this webpage: https://bit.ly/3rRa0Ak2) SELFISH SUPERGENE IN ANTSThe objective of the Ph.D. will be to investigate the mechanisms by which a social supergene distorts Mendelian transmission. In the Alpine silver ant, Formica selysi, a large supergene controls colony social organization, and the haplotype associated with multiple-queen colonies selfishly distorts transmission by killing progeny that did not inherit this haplotype. In collaboration with the team, you will identify the selfish genetic element and characterize the process causing brood developmental arrest. The research will provide insights into the role of selfish genetic elements in the evolution of supergenes controlling complex phenotypes.Your responsibilities:You will develop research on selfish genetic elements (toxin-antidote elements) present in supergenes. This will involve field sampling, breeding experiments, molecular analyses (transcriptomics, proteomics, RNAi), developmental studies, and genome analyses.Your qualifications:In order to complete our team, we are looking for someone with a Master’s degree in biology, life sciences, genetics, or related subjects.

Offre de thèse : IMPRINTING AND PLOIDY IN BUMBLEBEES

PhD: IMPRINTING AND PLOIDY IN BUMBLEBEES, LEICESTERDeadline for applications: 7 January 2022Project highlights– Building on NERC funded and CENTA PhD work on bumblebees, an important pollinator.– How are imprinted diploid genes used in a haploid sex?– Are different genes imprinted at different stages?OverviewThis project asks how can imprinted genes exist in a haplodiploid organism. Genomic imprinting is when the expression of an allele is dependent on the parent it came from, Genomic imprinting is an important area of research in plant breeding and in evolutionary biology and has relevance to some human cancers and developmental syndromes.Recently, as part of a current NERC funded research grant and a CENTA 1 PhD, we have discovered imprinted genes in bumblebees (see Figure 1). This is a major finding and opens the door to multiple other questions. Bumblebees are haplodiploid, that is fertilised eggs (diploids) become females. Unfertilised eggs (haploids) become males. This leads to a paradox,  genomic imprinting restricts expression of certain genes to one parental allele. As a consequence, both maternal and paternal chromosomes are required for successful development. How can males function, given that we would predict a number of genes to be imprinted and therefore non-functional.A corollary of this, through a quirk of inbreeding in bumblebees, diploid males are easy to produce. How do these animals function give that they presumably have doubled the number of alleles compared to their haploid brothers? Previous work suggests that they have similar expression levels to haploid males, but what about the imprinted genes in these diploids.A final area of interest is imprinting at different stages. Our data shows imprinting in the adult bee. When does this arise? Are different genes imprinted at different stages?MethodologyThe student will produce haploid males from ten normal colonies. Diploid males will come from ten inbred colonies. RNA from these will be extracted. Imprinted gene expression will be analysed using candidate gene RNA-seq analysis.Imprinted genes showing interesting patterns (differences between females, haploid and diploid males) will have their gene expression altered using RNAi to examine the resultant phenotype.The reciprocal cross used in the initial work (NERC funded) will be repeated and this time samples will be taken at larval and pupal stages. They will be analysed using RNA-seq and GLMs to identify stage specific imprinted genes.Training and skillsThe student will be provided with training, as required, in R, a powerful and increasing popular statistical programming language, Python, a general-purpose, high-level programming language widely used in bioinformatics, molecular biology and bee husbandry.Training will also be provided in the preparation of both transcriptomic NGS libraries. The student will also become conversant with general molecular biology techniques such as PCR, qPCR and cloning.Partners and collaborationThis is a collaborative project between the lead supervisor Mallon and co-supervisor Rosato.  The supervisors have complimentary interests and expertise in gene expression and social insects and of next generation sequencing techniques to investigating these areas. Mallon will provide specific expertise in the role of epigenetics and gene expression, while Rosato provides expertise in candidate gene molecular biology. This proposal will benefit greatly from the ongoing collaboration between M and R in co-supervising a current PhD student working on bumblebees.Further detailsPlease contact Eamonn Mallon, Department of genetics and genome biology, University of Leicester, ebm3@le.ac.uk for further details. https://www2.le.ac.uk/projects/selabTo apply to this project please visit: https://le.ac.uk/study/research-degrees/funded-opportunities/centa-phd-studentships Possible timelineYear 1: Haploid males.

Offre de Postdoc : THE GENOMIC BASIS OF SOCIAL NICHE CONSTRUCTION DURING COLONY FOUNDING

POSTDOC: THE GENOMIC BASIS OF SOCIAL NICHE CONSTRUCTION DURING COLONY FOUNDING, MÜNSTER, GERMANYDeadline for applications: 6 January 2022The Institute for Evolution and Biodiversity at the University of Münster, Germany, is seeking to fill the position of a Postdoctoral Research Associate (Wissenschaftliche/r Mitarbeiter/in – salary level TV-L E 13, 100%) from the earliest possible date. The position is within the externally funded project SFB/TRR 212. We are offering a fixed-term full-time position until 31 December 2025 corresponding to the duration of the project.Your tasks:The position is part of the Collaborative Research Centre (SFB/TRR 212) entitled « A Novel Synthesis of Individualisation across Behaviour, Ecology and Evolution: Niche Choice, Niche Conformance, Niche Construction » (NC3: https://www.unibielefeld. de/fakultaeten/biologie/forschung/verbuende/sfb_nc3/3) and funded by the German Research Foundation (DFG).The project focuses on the genetic, epigenetic and transcriptomic basis of social niche construction during colony founding. Individual Pogonomyrmex californicus ant queens can choose to start a new colony alone (haplometrosis) or they can join or accept other co-founding queens (pleometrosis). During the first two weeks of colony founding, co-founding queens interact in multiple ways and so construct their individualized social niche. They either accept additional queens or they evict/kill them. Matched interactions, where pleometrotic queens interact with each other, lead to a fitness gain whereas mismatched interactions, where haplometrotic and pleometrotic queens interact, lead to a fitness loss (for one or both). The frequency of these alternative founding strategies varies within and among subpopulations. The first funding period revealed the genomic and genetic architecture of this social niche polymorphism. In the second funding period, we will focus on three aims.Confirming and experimentally testing candidate genes and epigenetic mechanisms (histone modification and DNA methylation), that we identified in the first funding period.Develop a generalized evolutionary framework/model that takes into account the relation between genotype, phenotype, individualized social niche and fitness.Understand why colony founding above a certain number of cofounding pleometrotic queens will always fail. Is this a constraint (division of labour) or an adaptation (spitefulness) in the context of the evolution of pleometrosis.The successful candidate will conduct behavioural field and laboratory studies in cooperation with Prof Jennifer Fewell (Arizona State University) in Arizona and California. The secondary emphasis will be on transcriptomic, genomic and epigenetic studies using a variety of methods (dsRNAi, ATACseq, ChIP-seq and pharmacological interventions). Hence practical familiarity and experience with some genomic techniques and bioinformatic tools is required (ideally demonstrated through publications).Our expectations:The successful candidate will be a highly motivated scientist, interested in interdisciplinary work in the framework of the NC3 network. They will have a doctoral degree (or a comparable qualification) in biology, preferentially with a focus on evolution, behavioural ecology, sociobiology, genomics, epigenetics or another related field. They will also have a background, and ideally some postdoctoral experience, in at least two of the following areas: working with live insects, molecular lab skills, genomics/transcriptomics and bioinformatics. They will have excellent communication skills and be able to work both independently and as part of a multidisciplinary team. The working language of the Institute and the lab is English, and good proficiency in spoken and written English is a requirement. German language skills are not a requirement, but a willingness to learn is desirable.Advantages for you:The Institute for Evolution and Biodiversity provides a stimulating research environment with a number of scientific groups researching diverse topics centred on different aspects of evolution. As a part of the Collaborative Research Centre SFB/TRR 212 the project will involve intensive collaboration with consortium partners at the Universities of Münster and Bielefeld. The University of Münster is an equal opportunity employer and is committed to increasing the proportion of women academics. Consequently, we actively encourage applications by women. Female candidates with equivalent qualifications and academic achievements will be preferentially considered within the framework of the legal possibilities. The University of Münster is committed to employing more staff with disabilities.

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.

Date de prise de poste envisagée : février 2022

Fin des candidatures : 14 janvier 2022

Offre de thèses : Ant population genomics & social supergene drive, University of Lausanne

2 PhD POSITIONS: Ant population genomics & social supergene drive, University of Lausanne



Two Ph.D. positions (graduate assistants) in evolutionary biology are available in the group of Prof. Michel Chapuisat at the Department of Ecology and Evolution, University of Lausanne, Switzerland. The successful candidates will join a group studying the evolution and genomic basis of social organization in ants (see http://www.unil.ch/dee/page7000.html).

1) THE EVOLUTION OF SUPERCOLONIALITY

The objective of the Ph.D. will be to investigate the evolution of supercoloniality in ants of the genus Formica. In the Swiss Jura mountains, the native wood ant Formica paralugubris forms large supercolonies, with hundreds of nests connected by trails and hundreds of queens in each nest. The evolution of such supercolonies is still poorly understood. High-throughput sequencing and population genomic analyses will provide high-resolution information on population structure, dispersal patterns, symbionts, and genomic basis of colony traits such as sex ratio. Comparative analyses will reveal if the supergene controlling polymorphic social organization in other Formica species has been fixed or lost in F. paralugubris, and if the same genes and alleles are associated with high colony queen number across the genus.

Your responsibilities:
You will develop research on the evolution of ant sociality and supercoloniality. This will involve field sampling, sequencing, population genomic and comparative genomic analyses. Depending on your interests and skills, behavioural and ecological experiments are also possible.

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, population genetics, molecular evolution and/or behavioural ecology. We are looking for a creative and driven person with excellent interpersonal skills.

Job information:
Expected start date in position: 01.03.2022 (or at earliest convenience)
Contract length: The initial contract is for 1 year, renewable twice for two years, up to a maximum of 5 years in total
Activity rate: 85%
Workplace: Lausanne – Dorigny

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. The working language in the group and in the Department is English for all scientific matters. Good command of English is needed, some knowledge of French would be a plus, but is not mandatory. The University of Lausanne offers state-of-the-art facilities, including excellent computer facilities and molecular labs.

2) SELFISH SUPERGENE IN ANTS

The objective of the Ph.D. will be to investigate the mechanisms by which a social supergene distorts Mendelian transmission. In the Alpine silver ant, Formica selysi, a large supergene controls colony social organization, and the haplotype associated with multiple-queen colonies selfishly distorts transmission by killing progeny that did not inherit this haplotype. In collaboration with the team, you will identify the selfish genetic element and characterize the process causing brood developmental arrest. The research will provide insights into the role of selfish genetic elements in the evolution of supergenes controlling complex phenotypes.

Your responsibilities:
You will develop research on selfish genetic elements (toxin-antidote elements) present in supergenes. This will involve field sampling, breeding experiments, molecular analyses (transcriptomics, proteomics, RNAi), developmental studies, and genome analyses.

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

Offre de Post-doc : Ant population genomics, social supergene evolution, University of Lausanne

POST-DOC: Ant population genomics, social supergene evolution, University of Lausanne

A Postdoctoral position is available in the group of Prof. Michel Chapuisat at the Department of Ecology and Evolution, University of Lausanne, Switzerland. The group studies social evolution. We are currently investigating the origin, evolution, and mechanisms of action of a supergene controlling social organization across Formica ants (see http://www.unil.ch/dee/page7000.html). Recent research showed that some species have three supergene haplotypes. F. selysi and F. cinerea commonly hybridize, raising the possibility of supergene introgression. The postdoctoral researcher will generate and analyse population genomics data to uncover key processes governing supergene evolution, including selection, genetic load, drive and introgression. This project will shed light on how supergenes arise, spread and shape complex alternative phenotypes.

Your responsibilities:
You will study the evolution of a social supergene. This will involve field sampling of multiple ant species, population analyses (e.g. sex-ratio, male production), sequencing, population genomic and comparative genomic analyses. Depending on your personal interests and skills, projects on genome evolution, molecular evolution, behavioural genetics and ecological genomics are also possible.

Your qualifications:
We are seeking to recruit an early carrier post-doctoral researcher with a PhD degree in evolutionary biology, genetics, genomics, bioinformatics or related fields. The ideal candidate should have skills and experience in one or more of the following fields: population biology, population genetics, comparative genomics, ecological genomics, molecular evolution. The candidate should have a convincing publication track-record, excellent inter-personal skills and a strong ability to work in a team.

The exceptional diversity and convergence in this system provides an opportunity to examine the different genetic routes to an adaptive phenotype and to connect micro- to macroevolutionary processes through examining patterns of inheritance of adaptive alleles across lineages.The project involves field collection of bumble bee queens in the western United States, rearing of colonies, developmental staging and dissections, transcriptome sequencing, and comparative analysis of transcriptome variation across several bumble bee morphs and species. Applicants must have a Ph.D. in a biology-related field, have a strong record of research involving both molecular and bioinformatic techniques, and an interest in evolutionary genetics/evo-devo. Experience in working with insects is desired, but not necessary.This experience provides numerous opportunities for training as PSU has a strong focus on Bioinformatics and Genomics, houses several project-relevant facilities in the PSU Huck Institute of Life Sciences (e.g., microscopy, genomics, proteomics, bioinformatics), is home to the Center of Pollinator Research and the Insect Biodiversity Center, and offers numerous cross-departmental seminars and programs. The postdoc will also engage the labs of Jeff Lozier (U. Alabama) and Jonathan Koch (USDA ARS, Utah) in this research.The Pennsylvania State University requires all applicants to register and complete the application form at the Penn State employment website (https://psu.wd1.myworkdayjobs.com/PSU_Academic/job/University-Park-Campus/Postdoctoral-Scholar—Hines-lab_REQ_0000021143-1). A complete application will include a cover letter detailing relevant experience and research interests, a current CV, and contact information for three professional references.

Offre de thèse : Role of gene regulation in the social control of queen behavioral specialization in ants, Mainz (Germany)

Registration deadline: 20 January 2022Application deadline: 27 January 2022The Libbrecht group at the Johannes Gutenberg University of Mainz (Germany) is offering a 3-year PhD position (DFG, fully funded with possibility of extension, 65% TVL E13) to study the role of gene regulation in the social control of queen behavioral specialization in ants. The PhD student will be supervised by Romain Libbrecht (JGU Mainz) in collaboration with Joe Colgan (JGU Mainz), René Ketting (IMB Mainz) and Franjo Weissing (University of Groningen), and will be integrated in the GenEvo research training program (https://www.genevo-rtg.de).Division of labor between specialized castes is central to the functioning and evolution of insect societies.Queens monopolize reproduction, while workers perform all the tasks necessary to maintain the colony. Queens are typically seen as egg production units, to the point where their function in insect societies has been compared to that of the germline in multicellular organisms. Some of our recent work has challenged this longstanding view by revealing unexpected flexibility in queens of the black garden ant Lasius niger. We have shown that the presence of workers inhibits brood care behavior in founding queens. Moreover, we found that removing workers from established colonies caused old queens to revert to expressing brood care. These results indicate that the presence of workers not only initiates, but also maintains the behavioral specialization of queens that can live up to 30 years. As a means to understand the molecular basis of queen behavioral specialization, we have also performed brain RNAseq to identify genes that differ in expression between queens with and without workers. In this project, we will ask the question: What are the gene regulatory mechanisms that regulate the gene expression changes underlying the social control of queen brood care behavior? The project will include empirical and theoretical components. The empirical investigations will involve the collection and experimental manipulations of ant colonies, extensive behavioral analyses, RNAi knockdown of candidate genes, molecular biology techniques, sequencing technologies (e.g., RNAseq, WGBS, ChIPseq) and associated bioinformatics analyses. The theoretical aspects will be developed in collaboration with Franjo Weissing, including via a research stay in his group at the University of Groningen.We are looking for a highly motivated student with a Master degree (or equivalent) in biology, good English skills, and a keen interest in evolutionary biology. Previous experience with social insects, molecular biology, statistics and bioinformatics is advantageous, but not required. The successful applicant will join an international, interactive, dynamic and English-speaking scientific environment in a brand new building with access to state-of-the-art, newly equipped laboratories and climate-controlled rooms. The JGU of Mainz hosts many excellent scientific institutions, and Mainz is a historic city located on the Rhine River with a large student population and a rich social and cultural life.Interested candidates should register to the IPP (https://ipp2.imb.de/registration) before 20 January 2022 and complete their application before 27 January 2022. Informal enquiries should be sent to Dr. Romain Libbrecht (romain.libbrecht@uni-mainz.de).The starting date for the position is 1 July 2022. The Johannes Gutenberg University of Mainz is interested in increasing the number of women in science. Applications from women are therefore strongly encouraged. In addition, qualified candidates with disabilities will be preferred.Dr. Romain LibbrechtAssistant Professor / Junior Group LeaderInstitute of Organismic and Molecular EvolutionJohannes Gutenberg UniversityMainz, Germany+49 6131 3927852
