Adaptive radiations are extremely useful to understand factors driving speciation. A challenge
in speciation research is to distinguish forces creating novelties and those relevant to …

Invasive fish species can have major impacts on freshwater faunas, particularly in isolated
systems harbouring adaptive animal radiations. Here, we report on the occurrence and recent …

The significance of sympatric speciation is one of the most controversial topics in evolutionary
biology. Theory suggests that different factors can lead to speciation in full geographical …

Ancient Lake Poso in Central Sulawesi, Indonesia, is among the deepest lakes in Asia, and
hosts a largely endemic fauna of fishes, crustaceans, and molluscs. Introduction of non-…

This study investigated the impact of the third dimension in geometric morphometrics (GM)
using sailfin silversides (Telmatherinidae) from the Malili Lakes of Sulawesi (Indonesia). The …

Strong disruptive ecological selection can initiate speciation, even in the absence of physical
isolation of diverging populations. Species evolving under disruptive ecological selection …

Isopods of the species Ligia oceanica are typical inhabitants of the rocky intertidal of the
northern European coastline. The aim of this study was to assess the genetic structure of this …

Disruptive natural selection on traits related to resource exploitation may lead to differential
adaptation and finally to speciation. Trait utility, the performance of traits in terms of fitness, is …

Agricultural drainage ditches are common structures in cultivated lowland areas across
Europe. These artificial linear water bodies are interconnected to form networks that can offer …

(1) Background: Adaptive diversification of complex traits plays a pivotal role in the evolution
of organismal diversity. In the freshwater snail genus Tylomelania, adaptive radiations were …
