Document Summary
Biol 208: community structure and assembly (march 17, 2014: community concepts and description, dominance and diversity, lognormal distribution, rank abundance curves, concepts of assembly & ecological filters, abiotic: environmental complexity and disturbance, biotic: competition, predation, keystone species & ecosystem engineers. *log # of survivors (for survivorship curves) on the y-axis: final exam is, 2 hours long, culmulative, approx. half of the material that is tested on will be from material learned. After lecture exam 2: what is a community, *group of interacting species in some defined area and point in time. Interaction of different populations of different species: population: group of individuals form same species, boundary is vague unless you are talking about a lake/pond community, community structure is specific composition of individuals. *a better approach is to protect the community that the endangered/threatened individual is a part of. Supported by science: *service: conservation of these organisms provides services for people. Wetlands natural water filtration and flood prevention.
