Community structure changes over a range of time scales, from annual to decadal to millenial
time periods. Temporal patterns of community organization and their sensitivity to
environmental changes can indicate their stability to anthropogenic changes.
Community structure changes over short time periods as sizes of interacting populations
respond to seasonal and annual variation in environmental conditions. Changes in
resource quality, competition, and predation lead to population irruptions of some species
and local extinction of others, thereby affecting their interactions with other species and
leading to changes in community structure.
Ecological succession, the sequential stages of community development on newly
exposed or disturbed sites, is one of the best documented ecological phenomena and
has provided a unifying concept that integrates species life history strategies, population
behavior, community dynamics and ecosystem processes. Early successional communities
typically are dominated by relatively generalized ruderal species with high mobility and
rapid reproductive rates. Later successional stages are increasingly dominated by species
