Topic: Community ecology

 Community ecology - Wikipedia, the free encyclopedia
Community ecology is the study of the distribution, abundance, demography, and interactions between populations of coexisting species.
It is part of the division of ecology known as synecology that studies the organization of ecosystems specifically at the level of the biotic community (or biocoenosis).
Community ecology focuses on relationships between species, including the study of food webs, energy flow, and nutrient flow.

 Institute for Social Ecology - Social Ecology and Community Development
Therefore, a primary task in the process of community development is the recreation of local community, and a key component in that task is the identification of humanly scaled boundaries and the reclamation of a sense of place, be it rural village, small town, or urban neighborhood.
Social ecology suggests that such confederations might form a “commune of communes,” a commonwealth which could extend from the local to the regional to the continental level and beyond, to result in an ultimate unity through diversity.
Several community land trusts were created to remove particular lots from the real estate market forever, and to guarantee their continued use as a community resource.

 Ecology (Stanford Encyclopedia of Philosophy)
Contemporary ecology consists of a patchwork of sub-disciplines including population ecology, community ecology, conservation ecology, ecosystem ecology, metapopulation ecology, metacommunity ecology, spatial ecology, landscape ecology, physiological ecology, evolutionary ecology, functional ecology, and behavioral ecology.
Community ecology consists of models of interacting species, forming an ecological “community,” in which each species is treated as a unit.
In the type of population ecology that was discussed earlier (in Section 2), populations were characterized by their state variables, parameters such as size or density describing the population as a whole and—with two exceptions—ignoring individual differences.

 Communities and Succession
Although Clements’ work continued to be enormously influential, its stress on deterministic climax communities drew increasing criticism from ecologists in the 1930s, especially from those who were interested in adding the study of animals to ecology.
Overall, we expect to see essentially the same recorded variation in all communities, since this is a function of both inherent stability and the constancy of the environment.

A community is defined as an association of interacting populations, usually defined by the nature of their associations or the habitat they use.
Ecotones are characterized by a mix of species from both communities, or by species that are unique to the ecotone e.g.
Another group proposed that communities were merely chance assemblages of different species with similar environmental preferences; what was recognized as a community was often a change in the dominance of one species to another.

A community with a certain species richness with equal relative abundance of each species would have a greater diversity than a second community with the same species richness with a few common species and many rare ones.
Among the pioneers of community ecology, there were two divergent views on why certain combinations of species are found together as members of a community: the individualistic hypothesis and the interactive hypothesis.
Determining the effects of interspecific factors on species diversity and structure in communities is an important goal in ecological research, as is determining the relative significance of environmental patchiness in community structure.
