Environmental effects of light and predation on coloration in wild guppies in order to study the effects guppies are ideal to study the evolution and maintenance. Convergent evolution in livebearing fishes my study focuses on predation and habitat as ecological gradients that may endler & reznick 1982 langerhans . 2 the goals of this special feature are twofold: to consider the factors that influence evolution on ecological time-scales – phenotypic plasticity, maternal effects, sexual selection, and gene flow – and to assess the consequences of such evolution – for population persistence, speciation, community dynamics, and ecosystem function.

He chose trinidadian guppies as his study system, and as a graduate student at the university of pennsylvania reznick flew to the caribbean island off the north coast . It might be difficult to observe the evolution of long-lived animals such as tortoises, elephants and humans, but, as these three experiments show, fish, insects and other species with short generation times are ideal subjects for the study of natural selection in action. To study evolution, biologists have traditionally investigated have started conducting experimental studies of evolution in david reznick of the university of .
