RNR 2101 : RNR 2101 Ecology Exam 1 Notes
Document Summary
The scale of ecology: the players more research on these, cheaper and easier. Individuals behavior, physiology, etc. within a species: populations population growth and evolution in a single species. Climate combination of amount of rainfall and when, temperatures: seasonal cycle, northern hemisphere has spring equinox as equator faces the sun. Hemisphere has autumnal equinox: northern hemisphere has summer as it tilts toward the sun. Southern hemisphere has winter as it tilts away from the sun: northern hemisphere has autumnal equinox as equator faces the sun. Hemisphere has spring equinox: northern hemisphere has winter as it tilts away from the sun. In the southern hemisphere, oceans moderate temperature, cooler: temperature declines with elevation as air expands, loses energy, and cools. Atlantic and gulf patterns extend into midwest: no sunlight/water, no plants, no animals. Low conductive heat gain from ground: ectothermic animal thermoregulation.
