Extreme environments and the origins of biodiversity: adaptation and speciation in sulphide spring fishes
Organisms adapted to physiochemical stressors provide ideal systems to study evolutionary
mechanisms that drive adaptation and speciation. This review study focuses on livebearing …

Evolution in extreme environments: replicated phenotypic differentiation in livebearing fish inhabiting sulfidic springs
We investigated replicated ecological speciation in the livebearing fish Poecilia mexicana
and P. sulphuraria (Poeciliidae), which inhabit freshwater habitats and have also colonized …

Toxic hydrogen sulfide and dark caves: phenotypic and genetic divergence across two abiotic environmental gradients in Poecilia mexicana
Divergent natural selection drives evolutionary diversification. It creates phenotypic diversity
by favoring developmental plasticity within populations or genetic differentiation and local …

Toxic hydrogen sulfide and dark caves: life‐history adaptations in a livebearing fish (Poecilia mexicana, Poeciliidae)
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 …

Impacts of heavy metal pollution on the ionomes and transcriptomes of Western mosquitofish (Gambusia affinis)
Our understanding of the mechanisms mediating the resilience of organisms to
environmental change remains lacking. Heavy metals negatively affect processes at all …

Genetic differentiation and selection against migrants in evolutionarily replicated extreme environments
We investigated mechanisms of reproductive isolation in livebearing fishes (genus Poecilia)
inhabiting sulfidic and nonsulfidic habitats in three replicate river drainages. Although sulfide …

Natural and sexual selection against immigrants maintains differentiation among micro‐allopatric populations
Local adaptation to divergent environmental conditions can promote population genetic
differentiation even in the absence of geographic barriers and hence lead to speciation. But …

Acoustic and visual stimuli combined promote stronger responses to aerial predation in fish
Bird predation poses a strong selection pressure on fish. Since birds must enter the water to
catch fish, a combination of visual and mechano-acoustic cues (multimodal) characterize an …

Local adaptation and pronounced genetic differentiation in an extremophile fish, Poecilia mexicana, inhabiting a Mexican cave with toxic hydrogen sulphide
We investigated genetic differentiation and migration patterns in a small livebearing fish,
Poecilia mexicana, inhabiting a sulfidic Mexican limestone cave (Cueva del Azufre). We …
