Recent biological analyses suggest that reductions in dispersal ability have been key drivers
of diversification across numerous lineages. We synthesise emerging data to highlight …

Repeatedly and recently evolved sympatric morphs exhibiting consistent phenotypic
differences provide natural experimental replicates of speciation. Because such morphs are …

Freshwater ecosystems support the highest biological diversity per unit area on the planet,
despite occupying much less area than terrestrial and marine systems. Freshwater …

Biologists have long been intrigued by apparently predictable and repetitive evolutionary
trajectories inferred across a variety of lineages and systems. In recent years, high …

Aim Genoty**‐by‐sequencing (GBS) and similar reduced‐representation sequencing
methods, such as restriction site‐associated DNA sequencing (RADseq), have been …

Abstract Arctic Grayling (Thymallus arcticus) are among the most widely distributed and
abundant freshwater fish in the Yukon Territory of Canada, yet little information exists …

South American galaxiids occupy both Patagonia and the ichthyogeographic Chilean
Province, encompassing glacial Andean deep lakes, shallow plateau lakes, reservoirs, short …

Recent genomic analyses have highlighted parallel divergence in response to ecological
gradients, but the extent to which altitude can underpin such repeated speciation remains …

Distinguishing neutral and adaptive genetic variation is one of the main challenges in
investigating processes sha** population structure in the wild, and landscape genomics …

Longitudinal movement plays fundamental role in habitat colonization and population
establishment of many riverine fish species. Movement patterns of amphidromous fish …
