Document Summary
Environments are inherently unstable because they want to change. Physiology + dynamic environment physiology + dynamic environment. Ecology: study of interaction of organisms and their environment o o. Environment is biotic (living) and abiotic (non-living - not dead though) Environmental science: application of ecology in real life. Organismal ecology: usually both physiological ecology and behavioral ecology happening at same time o. Physiological ecology: how organisms are physically and chemically adapted to their environment. Needs to be adapted to salinity, weather, predation, etc. Camouflage - hide or allows for attack. Digestion - physiological response to what"s available in environment. Long term: frog that can freeze and live when it gets warm. Short term: bats awakening from hibernation with brown fat that releases heat energy that allows for fast adapting to environment o. Behavioral ecology: how the action/inaction of an individual organism contributes to its survival and reproductive success. Requires energy and allows for exposure to environment, predators, etc.
