Document Summary
An organism"s life history: a record of major events related to its growth, development, Lecture 6: chapter 7 biob50 reproduction and survival. Individuals within species differ in their life histories: life history strategy: of a species is the timing and nature of life history events averaged across all the individuals in the species. Shaped by the way the org divides its energy and resources in reproduction, growth and survival. Environmental differences: phenotypic plasticity: a single genotype may produce different phenotypes under different environmental conditions. Example is the temperature and growth rate of plants: another type of phenotypic plasticity, a single genotype produces discrete types or morphs with few or no intermediate forms. Omnivore morph: eat on algae and detritus, can turn into carnivore morphs when fed on fairy shrimp, more slowly growing. Carnivore morph: feed on fairy shrimp, bigger mouths, stronger jaw muscles, grow faster.
