SAS' Ecology Page

• models that describe the growth of populations (e.g. r- and k-selection).
• regulation of population size by abiotic factors (e.g. niche availability, pollution),
• regulation of population size by biotic factors (e.g. food availability, predation),

• Predator-prey interactions,
• parasitism
• commensalism
• symbiosis
• affects of abiotic factors that affect community size (e.g. habitat size)

Students will be able to describe ecosystem dynamics, including the following:

• energy flow through an ecosystem (e.g. food web and trophic levels),
• carbon cycle,
• nitrogen cycle,
• oxygen cycle,
• phosphorus cycle,
• sulfur cycle

Students will be able to discuss global issues, such as the following:

• local population extinction due to habitat destruction, pollution, non-native species, etc.,
• affect of human activities upon local ecosystems and biomes.
