Bremen: PhD, genetic incomp. and mate choice, parasitoid wasps |
PhD position: Genetic incompatibility and mate choice in parasitoid wasps A PhD position is available for 3 years (payment 50% TVâL E13) in the population ecology and evolutionary ecology group, headed by Prof. Dr. Thomas S. Hoffmeister, at the University of Bremen, Germany. The University of Bremen comprises 19,000 students and supports a broad range of academic disciplines. The ambition and success of its research strategy is reflected in its being one of eleven universities, selected within the German "Excellence Initiative". Project outline: Allelic incompatibility between individuals of the same species should select for mate choice based on the genetic makeâup of both partners at loci that influence offspring fitness. Therefore, mate choice may be an important driver of allelic diversity. A complementary sex determination (CSD) system is responsible for intraspecific allelic incompatibility in many species of ants, bees, and wasps. CSD may thus favour disassortative mating and in this, resembles the MHC of the vertebrate immune system, or the selfâincompatibility (SI) system of higher plants. The aim of this project is to analyse mate choice behaviour in the parasitic wasp Bracon brevicornis (Hymenoptera, Braconidae), thereby disentangling the impact of indirect (kin recognition) and direct (allele recognition) influences of the genetic composition of mating partners. The project will focus on proximate and ultimate cues of mating preferences alike and consist of fieldwork as well as laboratory experiments and molecular work. There is flexibility in the programme and the precise direction and emphasis of the project will be determined by collaboration between the student and the supervisors. Applicants must have a masterâs degree, or equivalent, in a relevant subject, e.g. ecology, animal behaviour, entomology and/or evolutionary biology. We expect an excellent knowledge of the English language in both writing and speaking. The successful candidate will receive high quality training in all relevant skills, conduct innovative research in a lively and active research group, and participate in teaching activities at the BSc or MSc level. The University of Bremen has received a number of awards for its diversity policies and offers a family friendly working environment. We strive to increase the number of international researchers and particularly solicit applications from suitably qualified candidates. Applications from female candidates and applications of academics with a migration background are explicitly welcome. Disabled persons with the same professional and personal qualifications will be given preference. Applications should be sent include a scan of the Masterâs diploma, a transcript of records, a CV, and a short proposal explaining how the applicant would approach the project, including specific hypotheses (maximum 1 page including references). Two potential researchers should be mentioned in the cover letter who are willing to supply letters of reference. Applications should be sent by email in a single pdf to Mrs. Inae KimâFrommherz (inaekf@uniâ bremen.de) until 31.12.2014. Informal inquiries to the position can be directed to Dr. Andra Thiel (thiel@uniâbremen.de). |
