Data from: Anthropogenic hybridization between endangered migratory and commercially harvested stationary whitefish taxa (Coregonus spp.)

Jan Dierking, Luke Phelps, Kim Præbel, Gesine Ramm, Enno Prigge, Jost Borcherding, Matthias Brunke & Christophe Eizaguirre
Natural hybridization plays a key role in the process of speciation. However, anthropogenic (human induced) hybridization of historically isolated taxa raises conservation issues. Due to weak barriers to gene flow and the presence of endangered taxa, the whitefish species complex is an excellent study system to investigate the consequences of hybridization in conservation. We focused on three naturally reproductively isolated whitefish taxa in Germany: the endangered, anadromous North Sea houting (NSH) and Baltic houting (BH),...

Data from: The contribution of post-copulatory mechanisms to incipient ecological speciation in sticklebacks

Joshka Kaufmann, Christophe Eizaguirre, Manfred Milinski & Tobias L. Lenz
Ecology can play a major role in species diversification. As individuals are adapting to contrasting habitats, reproductive barriers may evolve at multiple levels. While pre-mating barriers have been extensively studied, the evolution of post-mating reproductive isolation during early stages of ecological speciation remains poorly understood. In diverging three-spined stickleback ecotypes from two lakes and two rivers, we observed differences in sperm traits between lake and river males. Interestingly, these differences did not translate into ecotype-specific...

Data from: Genomic atolls of differentiation in coral reef fishes (Hypoplectrus spp, Serranidae)

Oscar Puebla, Eldredge Bermingham & W. Owen McMillan
Because the vast majority of species are well-diverged, relatively little is known about the genomic architecture of speciation during the early stages of divergence. Species within recent evolutionary radiations are often minimally diverged from a genomic perspective, and therefore provide rare opportunities to address this question. Here, we leverage the hamlet radiation (Hypoplectrus spp, brightly colored reef fishes from the tropical western Atlantic) to characterize genomic divergence during the early stages of speciation. Transect surveys...
