Life history tradeoffs examples
Evolutionary tradeoffs can be present in a form called life history tradeoffs, which can be defined as the decrease in fitness (essentially, lifetime reproductive success) caused by one life history trait as a result of the increase in fitness caused by a different life history trait. Life history traits are traits closely linked to fitness, such as traits associated with growth rate, body size, stress response, timing of reproduction, offspring quantity/quality, longevity and dispersal.
