Ph.D. Scholarship: Population genomics of parallel evolution in 
Icelandic Arctic charr *
What are the molecular underpinnings of parallel evolution? Do the same 
pathways, genes or even alleles contribute to divergence in multiple 
isolated populations within a species?
These and related questions will 
be addressed by a team of researchers, and a capable Ph.D. student 
responding to this advertisement. The Ph.D. project utilizes the 
parallel evolution of a small benthic variety of Arctic charr 
/(Salvelinus alpinu/s) in Iceland and is designed to investigate the 
genetics of this recent, rapid and repeated diversification.
 
Project outline
 
Many key questions of evolutionary genetics can now be investigated in 
detail due to theoretical advances and high throughput molecular 
techniques. The project is built on extensive ecological work on Arctic 
charr, a cold adapted salmonid that invaded Icelandic freshwaters after 
the last ice age (about 12,000 years ago). In multiple habitats, 
especially spring fed streams and lakes, charr have diversified into 
limnetic and benthic forms, and in some cases they coexist in sympatry. 
*The principal objective of the research is to identify key genes and 
pathways that associate with ecological specialization (e.g. morphology, 
life history characteristics) in Arctic charr.*The Ph.D. project��s aims 
are to: i) Identify SNPs that associate with dwarfism and/or morphotype 
and assess if and how variation at these loci correlates with ecological 
specializations across multiple populations. ii) Test whether genes that 
associate repeatedly with ecological specializations are under positive 
selection or if they have experienced relaxation of purifying selection.
 
Ideal candidate and requirements
 
We are seeking a student with dedication, drive and good theoretical 
background in population genetics and evolution and an interest in the 
genetics of divergence. The work involves planning and executing 
sampling in the field, acquisition and analysis of high-throughput 
sequencing data and numerical analyses. The position will be at the 
University of Iceland and the work will take place there.Experts at the 
University of Guelph, Canada, the University of Aarhus, Denmark, and the 
H��lar University College, Iceland, will also participate in the project.
 
Qualifications
 
The applicant must have completed a M.Sc. degree in Biology or related 
fields from a University approved by the University of 
Iceland's Graduate School. Those with an advanced degree including at 
least a 60 ECTS credits thesis project will be given precedence.
 
Terms of employment
 
The PhD study should be completed within four years of full time study. 
The PhD-student may be involved in teaching, for two semesters maximum.
 
Application
 
Applicants should send a letter of intent (maximum two pages) explaining 
your interest in working on this project, why they want to pursue a 
Ph.D., what they hope to gain and learn during their PhD studies and 
what makes them suitable for this project. They should also send a CV, 
transcripts of university diplomas, courses taken at bachelor and 
masters level, degree project thesis and names and contact information 
of two persons that could provide letters of references. Applications 
should be sent before March 15th, 2015, to

University of Iceland
 
The student will join the Arctic charr group at the Institute of Life 
and Environmental Sciences, under the supervision of Sigurdur S. 
Snorrason, Arnar Palsson and Zophonias O. Jonsson. The Arctic charr 
group consists of several Ph.D. students and senior personnel, and has 
collaborators in Iceland, Denmark and Canada. The combined expertise 
covers population ecology and genetics, molecular biology and 
bioinformatics. At the institute we have well equipped molecular biology 
labs, and instruments and computer pipelines for high throughput 
sequencing, are accessible there or at collaborating centers.
 
The University of Iceland strives to work against workplace 
discrimination and to offer equal opportunities to everyone.
