Swimming performance is a key feature that mediates fitness and survival in aquatic
animals. Dispersal, habitat selection, predator–prey interactions and reproduction are …

Under climate change, species unable to track their niche via range shifts are largely reliant
on genetic variation to adapt and persist. Genomic vulnerability predictions are used to …

Quantitative genetics provides a powerful framework for studying phenotypic evolution and
the evolution of adaptive genetic variation. Central to the approach is G, the matrix of …

Residing within the immense diversity of fishes on earth is an equally impressive array of
locomotor abilities. Some fish continuously swim virtually their entire lives; some move …

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 …

A fundamental question in evolutionary biology asks whether organisms experiencing
similar selective pressures will evolve similar solutions or whether historical contingencies …

Water impoundment imposes fundamental changes on natural landscapes by transforming
rivers into reservoirs. The dramatic shift in physical conditions accompanying the loss of flow …

To what extent are patterns of biological diversification determined by natural selection? We
addressed this question by exploring divergence in foraging morphology of threespine …

Anthropogenic habitat alteration creates novel environments that can alter selection
pressures. Construction of reservoirs worldwide has disturbed riverine ecosystems by …

Environmental gradients often lead to the parallel evolution of populations and species. To
what extent do such gradients also lead to parallel evolution of the sexes? We used guppies …
