M4: Community Ecology - Succession and Stability Flashcards
What are changes in communities following disturbance/environment change?
Ecological Succession
What are non-modified substrates?
Primary Succession
What are subsequent succession?
Secondary Succession
What are first to colonize in successional sequence?
Pioneer Community
What are the last community before disturbance?
Climax Community
Where is successions rapid?
Intertidal Communities
What happens when the ecosystem changes during succession?
Increase Productivity
- Higher Primary Production
- Higher Respiration
- Higher invertebrate biomass
What are the mechanisms of successions?
Facilitation, tolerance, and inhibition
What is the primary driver of succession and that many species attempt to colonize, but only few established?
Facilitation
What is many species colonize at earlier stage, but later successional species are those tolerant of later environmental conditions?
Tolerance
What are early occupants of an area modify and makes the habitat less suitable for future successional species?
Inhibition
What is the absence of change or the persistence of communities?
Stability
What is the stability of community when exposed to disturbance?
Resistance and Resilience
What is the maintaining of structure function?
Resistant Communities
What is the bouncing back (return to former state) from disproportion by disturbance?
Resilience Communities
