Abstract

We have recently received whole genome sequencing data from large number of individuals in Eurasian perch (>200 genomes) and we expect to receive WGS data from additional 384 perch individuals (genome size ca 1GB, ca 10X coverage). Therefore we need extra storage for genomic analyses as our currently used storage is full (we also went through the data to clean it up). These projects aim to identify the molecular mechanisms and ecological consequences of adaptation in freshwater fish species, focusing on Eurasian perch. We will combine whole-genome sequencing, analysis of archival and contemporary samples, experiments measuring ecologically relevant phenotypic variation and whole organism performance to: 1) identify parallel humic substance-driven selective footprints in boreal lakes based on whole-genome SNP analysis; 2) detect genomic regions and genes affected by contemporary brownification (recent climate change-driven increase in coloured dissolved organic carbon) based on whole-genome SNP analysis of archived samples.
