(2020) Genome-wide search for parent-of-origin allele specific expression in Bombus terrestris. Evolution Letters 4 (6), 479-490Deadline for applications: 7 January 2022 Project 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? Overview This 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? Methodology The 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 skills The 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 collaboration This 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.

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.

PhD: Studying bumblebee population dynamics and adaptations to understand plant-pollinator evolution under climate change Supervisors: Richard Gill, Jacob Johansson & Keith Larson
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 plant-pollinator network evolution under climate change. Taking a population biology approach (using complementary genetic approaches), 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.
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).
The PhD is competitively funded. The student will based at the Silwood Park campus of Imperial College and hosted by the Gill lab that is well equipped to study bee evolution and ecology. The student will be surrounded by world leading researchers in the disciplines of ecology, evolution and conservation. Facilities include 100 hectares of field site, new controlled environment rooms, microbiology facility, labs tailored for bee research and spacious workspace.
Please send your CV, a one page cover letter explaining why you are suitable for the project, and the names and e-mail addresses of two referees to Dr Richard Gill firstname.lastname@example.org by 6th January
2020. Informal enquiries for either are welcomed.

PhD positions to study the ‘omics cascade of bumble bee cold tolerance
Funding for PhD students is available at The University of Alabama as part of a recently awarded NSF Rules of Life project: “Bumble bee cold tolerance across elevations – From epigenotype to phenotype across space, time, and levels of biological organization”. PhD students will be involved in studying the links between genomic, epigenomic, transcriptomic, and metabolomic variation in relation to local thermal tolerance adaptation in montane bumble bees (lozierlab.ua.edu). The project will involve extensive high throughput sequencing of bees from wild populations and experimental colonies and the use of approaches like network theory to model and draw inferences from these complex data. Students will develop questions relating to ecological, evolutionary, or conservation genomics within the broader project objectives. The focus of the positions is flexible, and we expect there will be a great deal of collaboration and overlap among students, postdocs, and PIs on the project.
I am looking to recruit highly motivated students with interests in applying modern molecular and computational tools to address ecological and evolutionary questions in a non-model organism. Applicants should have a strong academic record (GPA > 3.0), an ability for clear verbal and written communication, and a desire to learn new skills! Students funded off the grant will participate in both laboratory molecular work (primarily generation of RNAseq and genome/epigenome sequencing libraries) and computational analyses, and applicants should thus have some degree of experience or interest in both aspects of the project.
The project will involve collaborations with Janna Fierst at UA, Michael Dillon and Franco Basile at the University of Wyoming, and James Strange at Ohio State. As part of these collaborations, there may be opportunities for fieldwork or experimental work with bumblebees, depending on student interests and expertise.

Diversity in body size underlies two of the organization principles of bumblebee societies: worker division of labor and caste determination, but little is known on the proximate mechanisms regulating body size and how they are socially regulated. This project explores how social cues such as pheromones, behavior, and queen regurgitates, interact with endocrine and epigenetic processes to regulate genes involved in larva development in the bumblebee Bombus terrestris. To meet these goals we integrate sociobiological, behavioral, physiological, and molecular approaches. The molecular methods include but are not limited to RNAseq and RNAi. The position will be located at the Hebrew University of Jerusalem, with opportunities to travel to the US for training and research.
* A PhD degree pending or obtained within the last three years in molecular biology, genetics, entomology, developmental biology, neurobiology, or related fields.
* Relevant lab expertise in developmental biology, neuroanatomy, bioinformatics, or molecular biology techniques. Experience with RNAseq, bioinformatics, RNAi, or CRISPR-Cas9 DNA editing, or with bees is advantageous.

Contrôle d’altitude chez le bourdon : les invariants optiques
Naviguer dans un environnement inconnu est une tâche aujourd’hui impossible à réaliser par un micro aéronef de quelques grammes, mais qui est réalisée tous les jours avec aisance par les insectes volants. Il existe donc des principes performants, basés en particulier sur des traitements adéquats de l’information visuelle, qui permettent aux insectes volants de réaliser des tâches de navigation spatiale avec précision. C’est précisément ces principes, encore peu connus, que nous voulons explorer, comprendre, modéliser, et simuler.
Le dispositif expérimental ci-dessous permet de tester différentes hypothèses en relation avec le contrôle d’altitude chez les insectes volants. Il se présente sous la forme d’un tunnel dans lequel on entraînera des bourdons à le traverser en fonction de différentes configurations optiques. Il conviendra ensuite de manipuler différents indices visuels (flux optique, lignes de perspective…) pour étudier les réactions du bourdon, on cherchera ensuite à mettre en évidence leur caractère invariant de certains d’entre eux au cours de vol.
Durée du contrat : 3 ans à partir du 1er octobre 2018
Salaire : 1460 € net /mois

Fully funded PhD opportunity in pollinator ecology at the University of Oxford, UK – UK or EU nationals only
Global declines of both wild and managed insect pollinators threaten ecosystem function and human food security. Pollinator declines have been specifically linked to declines in the abundance and diversity of floral resources, the use of agrochemicals, and introduction of novel parasites. We are interested in how these changes in the foraging environment, as well as social interactions, affect foraging behaviour in UK bumblebees.
The proposed project would use a new Unmanned Aerial Vehicle (UAV)-based insect tracking system based on harmonic radar tracking to track individual bumblebees while foraging. This study will improve understanding of how farm management systems, including crop types, field sizes, and field margins, as well as pasture, woodland and other semi-natural areas influence pollinator foraging patterns. The data will provide a foundation for modelling the necessary quantity, spatial pattern and temporal presence of floral resources in agricultural systems to maintain healthy wild pollinator communities.
The successful candidate will have a strong interest in pollinator ecology, insect learning, and agro-ecology and have experience piloting UAVs. Experience with radio frequency (RF) systems, microcontroller programming, and Geographic Information Systems (GIS) will be a significant advantage. For further details please contact email@example.com.
This project is at the interface between ecology and engineering, and involves a collaboration between the Oxford departments of Plant Sciences (Dr. Tonya Lander) and Engineering (Prof. Chris Stevens).
* Have, or be expected to obtain before the project begins, a BSc or equivalent in a relevant area (e.g. biology, zoology, environmental science).
* Experience in Unmanned Aerial Vehicle piloting.
* Interest in radio frequency (RF) systems use.
* Interest in microcontroller programming.
* High motivation with intellectual curiosity and rigour.
* Ability to work independently and manage multiple tasks.
* Excellent oral and written communication skills, including ability to present research at national and international symposia.
Deadline for applications is 9 MARCH 2018

GRADUATE STUDENT POSITIONS:
The Lozier Lab (lozierlab.ua.edu) at The University of Alabama, Dept. of Biological Sciences, is recruiting a highly motivated graduate students to start in the Fall 2018 semester. Students would work on projects related to ongoing NSF-funded studies of bumble bee population genomics to uncover signatures of adaptative and demographic processes within and among species. Students would specifically be working to generate and analyze population-level whole genome resequencing data across multiple species and broad environmental gradients at a large geographic scale, and could also be involved in sequencing and assembly of reference genomes from new bumble bee species using long-read sequencing technologies.
Students would have the opportunity to collaborate with project collaborators across institutions, and to integrate phenotypic data, including physiology and morphology, into genomic analyses.
Students with an interest in population genetics/genomics should contact Jeff Lozier (firstname.lastname@example.org), with a brief statement of interest, a resume/CV, and an informal academic history (e.g., GPAs, GREs, and relevant coursework list, etc.).

PhD STUDENTSHIP: DOMINANCE AND POLICING IN BUMBLE BEES, UNIVERSITY OF EAST ANGLIA
A fully-funded PhD studentship to start in October 2018 in Andrew Bourke’s group in the School of Biological Sciences, University of East Anglia, Norwich, UK, is now open for applications. The project is entitled ‘Dominance and policing in bumble bees’ and will use experimental and genetic methods (microsatellites, SNPs) to test hypotheses regarding the origin and maintenance of selfish egg-laying by bumble bee workers. The studentship will be funded by NERC as part of the EnvEast Doctoral Training Partnership (http://www.enveast.ac.uk/).
For further details of the project (BOURKEUBIO18EE) and instructions on how to apply, please follow this link:
The closing date for applications is Monday 8 January 2018.
A NERC-funded PDRA position is available for 34 months working at the Natural History Museum, London, with Professor Ian Barnes and Dr Selina Brace, on the recovery and analysis of DNA from bumblebee museum specimens. This work is part of a larger project investigating insect pollinator responses over a century of UK land-use change. The advertised position will focus on whole genome sequencing of museum specimens, and analysis of these data to infer past patterns of population size change, admixture and selection. The post-holder will work closely with Dr Richard Gill and his team in the Department of Life Sciences at the Silwood Park campus of Imperial College London, who are conducting population trait evolution and manipulative experiments as complementary components of the project. The project also involves working with the imaging and digitisation teams at the Natural History Museum, and museum curators and other leading researchers from around the UK. The overall aim f or the project is to better understand the dynamics of how insect pollinator populations have (and will) change in response to changes in land-use and associated factors, and how they adapt to newly emerging environments and the impact on fitness.
The post will be based at the Natural History Museum, and will make use of the Museum’s excellent molecular laboratory facilities and extensive collections. The successful applicant will be interested in the recovery of DNA sequences from museum specimens, and the application of these data in evolutionary biology and applying this to eco-evolutionary questions.
Salary will be £33,416 per annum plus benefits.
Informal enquiries can be addressed to Dr Selina Brace (firstname.lastname@example.org) or Prof Ian Barnes (email@example.com).

FUNCTIONAL GENOMICS OF DISEASE AND PESTICIDE SUSCEPTIBILITY IN BUMBLE BEES
SALARY $43,000-$47,500 per yr.
Applications are invited to join the Cameron Lab in the Department of Entomology at the University of Illinois. Research will focus on experimental studies of the functional genomics and ecological effects of the fungal pathogen Nosema bombi, and its interactive effects with neonicotinoid pesticides, on bumble bee health. We are looking for expertise in the laboratory production and bioinformatic analysis of gene expression data (RNAseq, qPCR, etc.).
The collaborative research team includes Dr. Ben Sadd, Illinois State University, (https://faculty.sharepoint.illinoisstate.edu/bmsadd) and James Strange, Utah State USDA Bee Biology Lab (https://www.ars.usda.gov/pacific-west-area/logan-ut/pollinating-insect-biology-management-systematics-research/people/dr-james-strange/).
The research includes experiments on both declining and stable populations of bumble bees, with the broad goal of understanding causal factors of decline in U.S. bumble bee populations. We will examine how different species vary in susceptibility to pathogens and pesticides, investigating how these stresses can interact to the detriment of bee viability. An integration of colony-level, whole-organism, cellular, and transcriptomic approaches will address how susceptibility is linked to decline status. The postdoc will play a key role in setting up and analyzing RNAseq data. The ultimate goal is to identify expression and genetic diversity associated with infection and pesticide susceptibility. Major responsibilities will be to participate in experiments and develop the transcriptome datasets.
A strong bioinformatics or statistical genetics/population genetics background with a PhD degree in a relevant area is required. Communication skills are essential; programming skills are desirable.
To apply for this position, please submit your CV and a Statement of your interest in the position, including discussion of how your skills interface with the project’s research needs, along with names and complete contact information for three professional references.
