Studies of female mate choice commonly use virgin females as test subjects, either to control
for the effects of mating or because virgin females are presumed to be more responsive to …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Extreme environments are characterised by the presence of physicochemical stressors and
provide unique study systems to address problems in evolutionary ecology research …

Environmental factors can promote phenotypic variation through alterations in the
epigenome and facilitate adaptation of an organism to the environment. Although hydrogen …

We investigated replicated ecological speciation in the livebearing fish Poecilia mexicana
and P. sulphuraria (Poeciliidae), which inhabit freshwater habitats and have also colonized …

Isolation by adaptation increases divergence at neutral loci when natural selection against
immigrants reduces the rate of gene flow between different habitats. This can occur early in …

Life‐history traits are very sensitive to extreme environmental conditions, because resources
that need to be invested in somatic maintenance cannot be invested in reproduction. Here …

The brain is a plastic organ, and so intraspecific studies that compare results obtained from
wild individuals with those from common‐garden experiments are crucial for studies aiming …

A long-held, but poorly tested, assumption in natural populations is that individuals that
disperse into new areas for reproduction are at a disadvantage compared to individuals that …

We investigated mechanisms of reproductive isolation in livebearing fishes (genus Poecilia)
inhabiting sulfidic and nonsulfidic habitats in three replicate river drainages. Although sulfide …
