The contemporary distribution of crenobiontic endemics in central Texas is enigmatic
because only some springs are occupied by crenobionts despite other unoccupied springs …

Climate changes have substantial impacts on the geographic distribution of montane lakes
and evolutionary dynamics of cold‐adapted species. Past climate cooling is hypothesized to …

Aim Alpine spring ecosystems have long been considered as highly isolated, island‐like
habitats. This presumption, however, is insufficiently supported empirically and conclusions …

Biodiversity is being lost at an alarming rate, but the rate of this loss is likely to be
underestimated as a result of a deficit in taxonomic knowledge (ie the Linnean shortfall) …

The evolutionary origins of modern taxa are best understood as arising from the interplay of
vicariance and dispersal. Vicariant events have long been considered responsible for …

Background Selective landscapes in rivers are made up by an array of selective forces that
vary from source to downstream regions or between seasons, and local/temporal variation in …

Desert aquatic systems are widely separated, lack hydrologic connections, and are subject
to drought. However, they provide unique settings to investigate distributional patterns of …

Introduction: While the biodiversity value of springs is recognised, it has not been
systematically compiled. The aim of the current study is to highlight the extraordinary …

A new genus and species of crangonyctid amphipod, Sicifera cahawba gen. & sp. nov., is
described from Dallas County, AL, USA, based on both morphological and molecular …

The razor clam genus Novaculina represents an example of a marine-derived, secondary
freshwater group. It was thought to comprise three species: N. gangetica (Ganges and …
