Life History Variations
- The life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle).
- Populations evolve to maximise their reproductive fitness, also called Darwinian fitness (high r value), in the habitat in which they live.
- Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategy.
- The rate of breeding varies from species to species:
- Some species breed only once in their lifetime (Pacific salmon fish and bamboo), they are called semelparous. Species with this pattern use up most of their resource budget in a single reproductive event, sacrificing their health to the point that they do not survive.
- Some species breed many times in their lifetime (birds and mammals), they are called iteroparous. They don't put all of their resources into a single reproductive event.
- Some produce large numbers of small sized offspring (oysters), whereas others produce small numbers of large sized offspring (birds and mammals).
