Description: Genome-level studies of the processes that drive population or species divergence have previously been reserved for model systems. However, over the past decade the cost of sequencing has plummeted allowing for the cost effective development of 100s or 1000s of loci in non-model organisms and providing increased power to detect population structure and signals of selection (population genomics) and to resolve evolutionary relationships (phylogenetics). Furthermore, the number of species with whole-genome sequence data is continually growing and an increasing number of taxa are becoming “genome-enabled.” These advances provide researchers with unprecedented levels of data to generate precise estimates of essential population genetic parameters and to develop probes for homologous loci for use in phylogenetic studies. In this symposium we present case-studies that display the diversity of next-generation sequencing methods used to study the evolution of fishes and the diversification of this diverse and ancient group.

Expected Audience: We expect a great deal of interest in this symposium as it addresses fundamental questions evolutionarily relationships and how biodiversity is generated, it will highlight the latest sequencing technologies and library preparation techniques, and will outline some of the fundamental questions that can be addressed using these tools. We expect that researchers from a diversity of disciplines including evolutionary biology, population genetics, phylogeography, phylogenetics, and conservation biology will attend our session.
