Learning objectives, Intro Biology 152, Ecology section (Turner, Fall 2011, Campbell 8 th edition) Lecture 7 – Community ecology: population interactions How do species interact, and how does this structure biotic communities? Key concepts Populations do not exist in isolation; individuals of different species constantly interact, and these interactions help shape the structure (who’s there and how many) of the biotic community. When two or more species rely on similar limiting resources, they may have negative effects on one another (competition); coexistence occurs when species are able to share the resources. Prey have a wide range of mechanisms to defend themselves from predation. Predators seldom consume all their prey and may be important in regulating the prey population. Learning objectives Explain how population interactions differ in their effects. Know the vocabulary used to describe population interactions and be able to categorize a given interaction correctly. Be able to reason from examples about the type of interaction that is occurring.
