Rapid evolution of escape ability in Trinidadian guppies (Poecilia reticulata).
Predators are widely assumed to create selection that shapes the evolution of prey escape abilities. However, this assumption is difficult to test directly due to the challenge of recording both predation and its evolutionary consequences in the wild. We examined these events by studying natural and experimental populations of Trinidadian guppies, Poecilia reticulata, which occur in distinct hi...
متن کاملLocal adaptation in Trinidadian guppies alters ecosystem processes.
Theory suggests evolutionary change can significantly influence and act in tandem with ecological forces via ecological-evolutionary feedbacks. This theory assumes that significant evolutionary change occurs over ecologically relevant timescales and that phenotypes have differential effects on the environment. Here we test the hypothesis that local adaptation causes ecosystem structure and func...

متن کاملFear, food and sexual ornamentation: plasticity of colour development in Trinidadian guppies.
The evolution of male ornamentation often reflects compromises between sexual and natural selection, but it may also be influenced by phenotypic plasticity. We investigated the developmental plasticity of male colour ornamentation in Trinidadian guppies in response to two environmental variables that covary in nature: predation risk and food availability. We found that exposure to chemical pred...
متن کاملPredicting the direction of ornament evolution in Trinidadian guppies (Poecilia reticulata).
Sexual selection is thought to be opposed by natural selection such that ornamental traits express a balance between these two antagonistic influences. Phenotypic variation among populations may indicate local shifts in this balance, or that different stable 'solutions' are possible, but testing these alternatives presents a major challenge. In the guppy (Poecilia reticulata), a small freshwate...
