Linking intraspecific and interspecific divergence is an important challenge in speciation research. X chromosomes are expected to evolve faster than autosomes and disproportionately contribute to reproductive barriers, and comparing genetic variation on X and autosomal markers within and between species can elucidate evolutionary processes that shape genome variation. We performed RAD seq on a 16 population transect of two cl...

Studying recent adaptive radiations in isolated insular systems avoids complicating causal events and thus may offer clearer insight into mechanisms generating biological diversity. Here, we investigate evolutionary relationships and genomic differentiation within the recent radiation of Alcolapia cichlid fish that exhibit extensive phenotypic diversification, and which are confined to the extreme soda lakes Magadi and Natron...

In this study, we used restriction site–associated DNA ( RAD ) sequencing to discover SNP markers suitable for population genetic and parentage analysis with the aim of using them for monitoring the reintroduction of the E urasian beaver ( C astor fibre ) to S cotland. In the absence of a reference genome for beaver, we built contigs and discovered SNP s within them using paired‐end RAD data, so as to have sufficient flanking...

Inexpensive short‐read sequencing technologies applied to reduced representation genomes is revolutionizing genetic research, especially population genetics analysis, by allowing the genotyping of massive numbers of single‐nucleotide polymorphisms ( SNP ) for large numbers of individuals and populations. Restriction site–associated DNA ( RAD ) sequencing is a recent technique based on the characterization of genomic regions fl...
