The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a
premier organism to study parallel evolution. These small fish have multiple distinct …

Similar forms often evolve repeatedly in nature, raising long-standing questions about the
underlying mechanisms. Here, we use repeated evolution in stickleback to identify a large …

Mutations of small effect underlie most adaptation to new environments, but beneficial
variants with large fitness effects are expected to contribute under certain conditions. Genes …

Replacing synthetic insecticides with transgenic crops for pest management has been
economically and environmentally beneficial, but these benefits erode as pests evolve …

Invasive species can be powerful models for studying contemporary evolution in natural
environments. As invading organisms often encounter new habitats during colonization, they …

Experimental introductions of species have provided some of the most tractable examples of
rapid phenotypic changes, which may reflect plasticity, the impact of stochastic processes, or …

Identifying the molecular mechanisms facilitating adaptation to new environments is a key
question in evolutionary biology, especially in the face of current rapid and human‐induced …

It is known that melanin pigments composed of black to dark brown eumelanin (EM) and
yellow to reddish-brown pheomelanin (PM) are widely distributed in vertebrates. Melanin …

The threespine stickleback, Gasterosteus aculeatus, has undergone dramatic increases in
abundance in parts of its historical native range, and it is also undergoing a major range …

Variation in lateral plating in stickleback fish represents a classical example of rapid and
parallel adaptation in morphology. The underlying genetic architecture involves …
