Spatial pattern of MHC class II variation in the great snipe (Gallinago media)
The hypothesis that spatial variation in selection regimes contributes to the high polymorphism in MHC variation is supported, and a role for selection in generating this spatial structure is suggested.
Recent Asian origin of chytrid fungi causing global amphibian declines
Panzootic chytrid fungus out of Asia Species in the fungal genus Batrachochytrium are responsible for severe declines in the populations of amphibians globally. The sources of these pathogens have…
Genomics and the challenging translation into conservation practice.
Evolution of black grouse leks female preferences benefit males in larger leks
From connectivity to isolation: genetic consequences of population fragmentation in capercaillie across Europe
The results agree with the concept of a gradual increase in genetic differentiation from connectivity to isolation, and from recent to historic isolation, which may have significant genetic and evolutionary consequences for surviving populations.
Structural genomic changes underlie alternative reproductive strategies in the ruff (Philomachus pugnax)
Using whole-genome sequencing, this work proposes an evolutionary scenario where the Satellite chromosome arose by a rare recombination event about 500,000 years ago and resolved the enigma of how such complex phenotypic differences can have a simple genetic basis.

Copying and sexual selection.
Non‐gradual variation in colour morphs of the strawberry poison frog Dendrobates pumilio: genetic and geographical isolation suggest a role for selection in maintaining polymorphism
The possibility that the observed variation in colour morphs is a consequence of a combination of local variation in both natural selection on an aposematic signal towards visual predators and sexual selection generated by colour morph‐specific mate preferences is discussed.
Patterns of variation in tail ornament size in birds
Elongated tail ornaments in four species of whydahs Vidua, the forktailed flycatcher Tyrannus savana and the Asian paradise flycatchers Terpsiphone paradisi did not show higher geographical variation than the body size characters, suggesting that there is no line of equilibria for these ornamments.
