Patterns in Communities
| Question | Answer |
|---|---|
| species richness | the number of species in a community |
| species evenness | the relative abundance of each species |
| species-area effect | another pattern of species richness is that larger areas usually contain more species than smaller areas do. This relationship is called... |
| disturbance | events that change communities, remove or destroy organisms from communities, or a;ter resource availability |
| stability | the tendency of a community to maintain relatively constant conditions |
| ecological succession | the gradual, sequential regrowth of a community of species in an area |
| primary succession | the development of a community in an area that has not supported life previously, such as bare rock, a sand dune, or an island formed by a volcanic eruption |
| secondary succession | the sequential replacement of species that follows disruption of an existing community |
| pioneer species | the species of organisms that predominate early in succession |
| climax community | the traditional description of succession is that the community proceeds through a predictable series of stages until it reaches a stable end point |
