abiotic components - ANSair, water, and non-living parts of soil

age-specific fecundity - ANSthe average number of female offspring produced by a female in a given age-class

altruism - ANSbehavior that has a fitness cost to the individual exhibiting it and a fitness benefit to the recipient, appears to contradict this pattern (queen bees giving themselves up for the queen to reproduce)

asymmetric competition - ANSone species suffers a much greater fitness decline than the other

Batesian Mimicry - ANSResemblance of an innocuous prey species to a dangerous species (Look dangerous but aren't dangerous)

behavior - ANSan action or response to a stimulus

behavioral biology - ANSstudy of how organisms respond to particular stimuli from those environments

biomes - ANSmajor groupings of plant and animal communities defined by a dominant vegetation type

boreal forest (taiga) - ANSforms on subarctic lands, dominated by highly cold-tolerant conifers; productivity is low, above-ground biomass is high because slow-growing tree species may be long-lived and become big

character displacement - ANSevolutionary change that occurs in species trait and enables species to exploit different resources 1 / 3

circadian clock - ANSmaintains a 24-hour rhythm of chemical activity-animals use sun for direction

climate - ANSthe prevailing, long-term weather conditions found in an area

commensalism - ANSoccurs when one species benefits, but the other species is unaffected

communication - ANSprocess in which a signal from one individual modifies the behavior of another individual

community - ANSconsists of species that interact with one another within a particular area

compass orientation - ANSmovement oriented in a specific direction

competition - ANSoccurs when individuals use the same resources

competitive exclusion principle - ANSit is not possible for species within the same niche to coexist

Constitutive / standing defenses - ANSdefenses that are always present (avoidance, poison, schooling and flocking that confuse predators)

Consumers - ANSeat living organisms

consumption - ANSoccurs when one organism eats or absorbs nutrients from another, increasing the consumer's fitness, but decreasing the victim's fitness

cost benefit analysis - ANSanimals appear to weigh the costs and benefits of responding to a particular situation in various ways

decomposer food chain - ANSMade up of species that eat the dead remains of organisms 2 / 3

Decomposers (Detritivores) - ANSObtain energy by feeding on the remains of other organisms or waste products

density independent - ANSdoes not depend on the number individuals in the population

Detritus - ANSThe waste products or dead remains of the other organisms

early successional communities - ANSdominated by species that : are short lived, small in stature and disperse their seeds over long distances

ecology; what is it's purpose? - ANS-study of how organisms interact with their environment -to understand the distribution and abundance of organisms

ecosystem - ANSconsists of all organisms in a particular region, along with non-living components

Ecosystem - ANSmultiple communites of organisms that live in an area along with abiotic components

emigration - ANSoccurs when individuals leave a population to join another population

eusoiaity - ANSsometimes altruistic behavior is involuntary; in bee population, workers sacrifice most/all of their direct reproduction to help rear the queen's offspring

experiments - ANSdesigned to simulate changed climate conditions and to record responses by the organisms present

Facilitation - ANSoccurs when early arriving species make conditions favorable for the arrival of later species

fixed action patterns (FAP's) - ANShighly inflexible stereotypical behavior patterns
