Genomic architecture of adaptive radiation and hybridization in Alpine whitefish

In this genomic study on Alpine whitefish radiations, the authors reveal details on the genetic architecture underlying the repeated eco-morphological diversification and the role of hybridization in the evolution of endemic whitefish species.

Genomic variation from an extinct species is retained in the extant radiation following speciation reversal

Genomic analysis of an Alpine whitefish radiation before and after human-driven lake eutrophication that led to the extinction of one species through hybridization shows that substantial parts of the genome of the extinct species persist within surviving species due to introgressive hybridization.

The coincidence of ecological opportunity with hybridization explains rapid adaptive radiation in Lake Mweru cichlid fishes

Recent studies have suggested that hybridization can facilitate adaptive radiations. Here, the authors show that opportunity for hybridization differentiates Lake Mweru, where cichlids radiated, and Lake Bangweulu, where cichlids did not radiate despite ecological opportunity in both lakes.
