The lake-dwelling fish, the Arctic charr Salvelinus alpinus is highly diverse both in phenotype and genotype. This takes the form of substantial between and within lake variation; in some places the latter being expressed as eco-morphologically distinct sympatric polymorphisms. In addition the species is of high conservation value in the UK. This expressed variation has led to taxonomy uncertainty and the suggestion of multiple endemic species in Scotland (Kottelat & Freyhof 2007). This project will use high resolution population genomic techniques to resolve a number of questions relating to the phylogenetic similarities between allopatric and sympatric populations to inform the taxonomic position of the species in Scotland and to help identify Evolutionary Significant Units that may require conservation protection.
Samples from a wide range of populations from across Scotland are already available (although there may be the opportunity to collect more) and outgroups from outside Scotland are available. Contemporary population genomics techniques to be deployed for analysis of neutral and adaptive SNPs and/or Evolutionary Significant Unit (ESU) SNPs generated by ddRADseq. The project will proceed in informal collaboration with a similar project in Ireland in order to maximise information across regions.
The successful candidate for this project is likely to be someone with a strong theoretical background in population genetics and who can show evidence of practical laboratory and analytical experience in an appropriate field.
