Document Summary
2483 ecology chapter 4: temperature and water. Some species can tolerate the seasonal changes and some choose to avoid it by behavioural or physiological process. Physiological ecology - interactions between physical environment and organisms. Actual distribution differs from the potential distribution - bc of other factors. If a value falls outside of the tolerance range, the species cannot be there: dispersal ability, interactions w other organisms, all physiological process have a set of optimal environmental conditions - deviations decrease the rate of the process. Climate envelope - range of climate conditions under which the species occurs. Acclimatization - adjust physiological, morphological, behaviour to lessen the effect of environmental change and minimize stress: short term, reversible. Ecotypes - populations with adaptations to unique environments: response to biotic and abiotic (competition, predators) factors, can eventually become separate species. Survival and functioning of organisms is related to their internal tem.
