ecology; what is it's purpose? - ANSWER -study of how organisms interact with their environment
-to understand the distribution and abundance of organisms
population - ANSWER group of individuals of the same species living in the same area, at the same time
community - ANSWER consists of species that interact with one another within a particular area
ecosystem - ANSWER consists of all organisms in a particular region, along with non-living components
abiotic components - ANSWER air, water, and non-living parts of soil
range - ANSWER geographical distribution; abiotic & biotic determine range
biomes - ANSWER major groupings of plant and animal communities defined by a dominant vegetation
type
climate - ANSWER the prevailing, long-term weather conditions found in an area
tropical wet forests (rain forests) - ANSWER found in equator regions where temperatures are high and
annual temperature is very low; produce abundant plant growth, lead to high above-ground biomass
, boreal forest (taiga) - ANSWER forms 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
tundra - ANSWER found throughout the arctic regions; low productivity and low above-ground biomass
and its treeless
permafrost - ANSWER soils are in a permanently frozen state; limits both the release and uptake of
nutrients
compass orientation - ANSWER movement oriented in a specific direction
true navigation - ANSWER ability to locate a specific place on earth's surface
circadian clock - ANSWER maintains a 24-hour rhythm of chemical activity-animals use sun for direction
communication - ANSWER process in which a signal from one individual modifies the behavior of
another individual
altruism - ANSWER behavior 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)
hamilton's rule - ANSWER can be expressed as Br>C, where B is the fitness benefit to the beneficiary, r is
the coefficient of relatedness, and c is the fitness cost to the actor
inclusive fitness - ANSWER the combination of direct and indirect fitness components
kin selection - ANSWER natural selection that acts through benefits to relatives and results in increased
indirect fitness
