Study Notes
Community Ecology
- A trophic level refers to a level of feeding positions in a food chain, with organisms grouped based on their feeding relationships.
Ecological Communities
- A guild describes a collection of species that use similar resources or have similar roles in a community.
Individualistic View
- The individualistic view of community ecology characterizes communities as a group of species that coexist in a given area, with each species responding individually to its environment.
Interspecific Interactions
- A type of interspecific interaction involves different species having different effects on each other, which can be positive, negative, or neutral.
Competitive Exclusion
- The competitive exclusion principle states that two species competing for the same limiting resources cannot coexist in the same ecological niche for an extended period of time.
