Fish inhabit environments greatly varying in intensity of water velocity, and these flow
regimes are generally believed to be of major evolutionary significance. To what extent does …

Differences in predation intensity experienced by organisms can lead to divergent natural
selection, driving evolutionary change. Western mosquitofish (Gambusia affinis) exhibit …

Animals may respond to ecological heterogeneity by genetic differentiation or phenotypic
plasticity. Responses of organisms to their ecology can include adaptation at various levels …

This book is a unique cross fertilization of aquatic ecology and aquaculture. It shows how
diets structure the digestive tract and its microbiota and, in turn, the microbiota influences life …

Extreme habitats are characterized by the presence of physio-chemical stressors, but also
differ in aspects of the biotic environment, such as resource availability or the presence of …

The structure of body size and shape divergence among populations of Poecilia vivipara
inhabiting quaternary lagoons in South-eastern Brazil was studied. This species is abundant …

A fundamental goal of evolutionary ecology is to understand the environmental drivers of
ecological divergence during the early stages of adaptive diversification. Using the model …

The expression of alternative phenotypes within a single species is often considered to be
the result of ontogenetic processes and specifically phenotypic plasticity responses to …

Invasive species that rapidly spread throughout novel distribution ranges are prime models
to investigate climate-driven phenotypic diversification on a contemporary scale. Previous …

Phenotypic trait differences among populations can shape ecological outcomes for
communities and ecosystems. However, few studies have mechanistically linked heritable …
