OPEN POSITION - PhD student: Marine evolutionary genomics

News: Jan 22, 2019

Apply by: 2019-02-11

The Department for Marine Sciences is Sweden's most complete academic environment for marine research and education, and it is one of few such institutions in Europe. The Department for Marine Sciences, founded 2015, brings together expertise in physical oceanography, marine chemistry, marine biology, marine geology, and marine heritage conservation. Thus the department has excellent opportunities to meet future challenges in marine research and education. The department of Marine Sciences are located with permanent staff in Gothenburg and at the research stations Kristineberg and Tjärnö on the Swedish west cost north of Gothenburg.

Subject area description
At the Marine Science department there is a long tradition in working with marine snails of the genus Littorina as models for studies of local adaptation, hybrid zones and speciation. This studentship will be embedded in a larger project that focuses on ecotype formation and the subsequent evolution of barriers to gene exchange in L. saxatilis. This species forms multiple ecotypes but we concentrate on contrasting adaptations to crab predation and wave action that occur in many parts of its North Atlantic distribution, particularly comparing Spanish and Swedish contact zones. Recently, we have discovered multiple polymorphic chromosomal inversions that appear to contribute to ecotype formation but which may also experience balancing selection. The studentship will focus on understanding the origin and evolution of these inversions and particularly the way in which they contribute to the parallel formation of distinct ecotypes in many parts of the species range.

Job assignments
The student will join an international team working on the evolutionary biology of Littorina based in the Department of Marine Science, both at Tjärnö Marine Laboratory and in Gothenburg, and at the University of Sheffield.

The student is expected to work on some combination of field or laboratory tests of the phenotypic and fitness effects of inversions, genomic signatures of inversion history and selection, and/or models of inversion evolution tailored to our observations of the Littorina model system.

Type of employment: Fixed-term employment, 48 months
Extent: 100%
Location: Department of Marine Sciences at Tjärnö
First day of employment: As agreed
