Document Summary
Ecology: attempts to explain the distribution, abundance and diversity of life, concerned with interactions between organism and their external environments (abiotic, biotic) Includes humans (in those interactions)-either with natural or built environment: ecology is not environmentalism, ecosystem* Molecules: ecology at levels of biological organization, ecosystem, community, population. Individual level: what adaptations allow the polar bear to survive, grow and reproduce: polar bears don"t hibernate, but females make dens, strategy to reproduce. The scientific method: case studies: disappearing marine iguanas: a case of population collapse by conrad. In ecology, we are concerned with: distribution, abundance, diversity. Key fact: temperature and rainfall are linked: observation: water vapour content of air is higher with warmer temperatures. Tropical rain forest distribution and climate: high temp and high precipitation, warm and therefore wet and super productive, this place is near equator. Tundra distribution and climate: cold and therefore dry (and stressful)
