Document Summary

Ecology = scientific interactions b/w organisms and their environment: global ecology = how regional exchange energy/materials influences functioning and distribution of organisms across biosphere (global ecosystem, landscape ecology = a landscape is a mosaic of connected ecosystems. Research in it looks at factors controlling exchanges of stuff across multiple ecosystems: ecosystem ecology = ecosystem is community of organisms in an area. This ecology focuses on energy flow b/w organisms and environment: community ecology = community is group of populations of different species in an area. Examines how species interactions (predation/competition) affect community structure and organization: population ecology = population is group individuals of same species living in an area. This analyzes factors that affect pop size and why/how it changes in time: organismal ecology = how organisms structure and behavior meet challenges posed by its environment. Climate influences distribution of animals on land: temp, precipitation, sunlight and wind affect climate especially.
