Genomics of sexual trait expression in black grouse


Department of Animal behaviour

, , Prof Kees van Oers Applications accepted all year round Funded PhD Project (Students Worldwide)

About the Project

An outstanding opportunity is available for a PhD student to work on the evolutionary genomics of sexual trait expression in an iconic avian model system, the black grouse (Lyrurus tetrix). The position is available in Joe Hoffman’s research group (www.thehoffmanlab.com) at the Department of Animal Behaviour at Bielefeld University and is fully funded for three years.

 

The PhD project

Since Darwin first coined the term ‘sexual selection’ to explain the evolution of exaggerated male traits, we have come to understand the complex interrelationships among these traits, the information they encode and the life histories of the animals they are embedded into.  Sexual selection is built on the idea that individual quality is signalled by the expression of these traits, yet a clear mechanistic understanding of the genetic architectures of sexual traits and the mechanisms regulating sexual trait expression remains elusive.

We know that inbreeding is an important component of individual quality, and several studies have documented inbreeding depression for sexually-selected traits.  Moreover, trait expression can be influenced by dynamic factors such as age and environmental variation, so epigenetic control mediated by body condition has been proposed as a means of regulating genotype-dependent sexual trait expression.  Resolving long-standing evolutionary questions about mate choice and sexual selection therefore requires a fundamental understanding of the genetic and epigenetic basis of sexual traits.

This project will use a variety of techniques to identify genome-wide epigenetic signatures associated with inbreeding and sexual trait expression in a classical lek model system, the black grouse. It will provide the PhD student with a fantastic opportunity to tackle sexual selection in a wild population using innovative and cutting-edge approaches.

 

Applicant’s profile

We seek a bright and highly motivated student who holds a good first degree and an M.Sc. or equivalent in a relevant topic (e.g. molecular ecology, population genomics, bioinformatics).  The ideal candidate will have strong quantitative skills, including proficiency in working in R and writing custom scripts. Practical experience of working with next generation sequence data would be advantageous, but full training will be provided. The candidate should also be able to work both independently and as part of a multidisciplinary team.  A high standard of spoken and written English is required.

 

The working environment

The PhD student will be based at the Department of Animal Behaviour at Bielefeld University, Germany (www.uni-bielefeld.de/biologie/vhf/index.html).  The department is the oldest of its kind in Germany and currently hosts seven principal investigators, nine postdocs and 15 PhD students. It offers a stimulating, supportive and highly international environment as well as an excellent research infrastructure.  The working language of the Department is English.

 

Bielefeld is a city of 325,000 inhabitants with an attractive historical centre and easy access to the Teutoberger Wald for hiking and other outdoor pursuits. It is an affordable and pleasant city to live in and is well connected to most major European cities.

 

This project is lab based and is located at Bielefeld University, but the PhD will also spend some time at the University of Lincoln (https://www.lincoln.ac.uk/home) and at the Netherlands Institute of Ecology (https://nioo.knaw.nl/en). The successful applicant will therefore benefit from an integrative, multidisciplinary training that will prepare her/him very well for a scientific career in behavioural ecology, molecular ecology and population genomics.

 

Remuneration

This generous PhD studentship is funded by the German Science Foundation (DFG) for a period of three years and includes health insurance. We welcome international applicants. The pay scale is TVL E13 (65%).  Funding will also be available for travel and for the student to attend workshops and conferences. 

 

Application procedure

To apply for this position, please provide: (i) a letter of motivation including a maximum 2-page statement of your research interests, relevant skills and experience; (ii) a CV including publication list; (iii) names and contact details of two referees willing to write confidential letters of recommendation; and (iv) please also state where you saw the position advertised. All materials should be emailed as a single PDF to: with ‘PhD application’ in the subject line.

 

The application deadline is 30th April 2021 and online interviews will take place shortly afterwards. For further information, please see www.thehoffmanlab.com, www.life-historyresearch.weebly.com and www.nioo.knaw.nl/nl/employees/kees-van-oers#quicktabs-qt_personal_page_nl=5. We also encourage you to contact Joe Hoffman (), Carl Soulsbury () or Kees van Oers () with any informal inquiries.

 

Bielefeld University has received a number of awards for its achievements in the provision of equal opportunity and has been recognized as a family friendly university.  The University welcomes applications from women.  This is particularly true with regard both to academic and technical posts as well as positions in Information Technology and Trades and Craft.  Applications are handled according to the provisions of the state equal opportunity statutes.  Applications from suitably qualified handicapped and severely handicapped persons are explicitly encouraged.
