Organismal Ecology- how individuals interact with their environment Population Ecology- how the numbers of individuals in a population change over time Community Ecology- interactions between species and the consequences of those interactions Ecosystem Ecology- all the organisms in a particular region along with nonliving components Climate- the prevailing long-term weather conditions in a particular region Biotic Factors- living, or produced by a living organism Abiotic Factors- not alive Tropical Wet Forests- found in equatorial regions where temps. and rainfall are high, variation in temp. is low, and enough rainfall is available to support year-round growth Subtropical Deserts- high average temperature with moderate temp variation. Low annual rainfall, found above and below 30 degrees of equator Temperate Grasslands- temperature is moderate, precipitation is low, and grasses dominate as plants Temperate Forests- relatively moderate to high precipitation, moderate temperatures, high diversity Boreal Forest- (taiga) south of Arctic circle, low temps w/ high variation, low diversity, low precipitation Arctic Tundra- precipitation and temperature is low, treeless, low diversity Marsh- lack trees and typically exhibit a slow but steady rate of water flow. Connected to lakes/streams Swamp- similar to marshes but are dominated by trees and shrubs. Like marshes, are productive Bog- unproductive and develop in depressions where water flow is low or nonexistent. The water in bogs is stagnant where oxygen is used up in decomposition. Acids build up, lacks nitrogen Temperate- having a climate with pronounced annual fluctuations in temperature but typically neither as hot as the tropics nor as cold as the poles Temperate Zones- temperatures that are moderate relative to the tropics and polar regimes, summers are warm and long, winters are cold and short Hadley Cells- cycle in global air circulation. Responsible for making the Amazon River basin wet and the Sahara dry. Air that is heated by the strong sunlight along the equator expands and rises Ferrell Cells- Aquatic- different environments are distinguished by depth of water and the rate of water movement Marine- distinguished by water depth

Productivity- the amount of energy used by a certain component of an ecosystem in a given area over a given period of time Behavior- action, response to a stimuli Proximate Cause- mechanistic, explains how actions occur in terms of the neurological, hormonal, and skeletal muscular mechanisms involved Ultimate Cause- evolutionary, explains why actions occur, based on their evolutionary consequences and history Fitness- ability of an organism to produce surviving fertile offspring Learning- an enduring change in an individual’s behavior that results from specific experience(s) Innate- behavior that is inherited genetically and does not have to be learned Fixed Action Patterns- highly stereotyped behavior patterns that occur in a certain invariant way in a certain species. Form of innate behavior
