Confirmation of the presence of non-native, self-sustaining brook trout Salvelinus fontinalis and genomic distinction between populations in southwest Germany.

Introduced to Europe from North America in the 19th century, Brook trout, Salvelinus fontinalis, can negatively impact native fish communities, yet self-sustaining populations remain rare in southern Germany despite a long stocking history. Here, we report a survey of 1618 electrofishing records from Baden-Württemberg,...

The genomic basis of adaptation to profundal habitats across the Swiss Alpine whitefish radiation.

When populations experience heterogenous environments multifarious divergent selection may lead to ecological speciation or even adaptive radiation. The underlying genetic architecture of adaptation can be simple or complex and is relevant for predicting evolutionary responses. Whitefish have radiated across Swiss peri...
