How population size shapes the evolution of guppy fish

A long-term fish experiment reveals how a mechanism called density dependence, in which the population growth rate slows as the number of individuals rises, affects population dynamics on time scales relevant for ecology and evolution. Study of fish in the wild sheds light on regulation of populatio...

Zusammenfassung:A long-term fish experiment reveals how a mechanism called density dependence, in which the population growth rate slows as the number of individuals rises, affects population dynamics on time scales relevant for ecology and evolution. Study of fish in the wild sheds light on regulation of population size.
