Document Summary
Wetland vegetation communities, succession and patterning: conceptual models of vegetation composition and wetland development, allogenic/autogenic succession, allogenic, replacement of a vegetation with another due to external factors. Climate change precipitation and temperature (how wet or warm) Pollution, nutrients, damming: autogenic, replacement of a vegetation with another due to internal biotic factors. Distinct assemblage of species that co-occur in space and time. Not much overlap with when the next community starts. Ducks unlimited spectral signature to identify wetlands: community. The assemblage of species at a given location/time. Vegetation community: successional theory, classic successional theory, community (clements) Secondary after fire, seed bank or soil to work with: rely on, existence of communities, autogenic succession, creating competition, one-directional change (bare to climax, sere: a community unstable in time, within a successional trajectory. If you leave the ecosystem alone, it will develop into something else: hydrarch succession. Slowly start building organics in the ecosystem. Using space for time = doesn"t work with wetlands.
