A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
Ecological classification or ecological typology is the classification of land or water into geographical units that represent variation in one or more ecological features. Traditional approaches focus on geology , topography , biogeography , soils , vegetation , climate conditions, living species, habitats , water resources, and sometimes also ...
Ecology is the study of the interactions between living organisms and their environment; enthnoecology applies a human focused approach to this subject. [2] The development of the field lies in applying indigenous knowledge of botany and placing it in a global context.
The Commission's 1997 report, Ecological Regions of North America, provides a framework that may be used by government agencies, non-governmental organizations, and academic researchers as a basis for risk analysis, resource management, and environmental study of the continent's ecosystems. [1]
An ecological metacommunity is a set of interacting communities which are linked by the dispersal of multiple, potentially interacting species. [1] [2] [3] The term is derived from the field of community ecology, which is primarily concerned with patterns of species distribution, abundance and interactions.
[1]: 181 The term was first coined by Alexander von Humboldt [1]: 16 and formalised by the International Botanical Congress in 1910. [1]: 182 [2] An association can be viewed as a real, integrated entity shaped either by species interactions or by similar habitat requirements, or it can be viewed as merely a common point along a continuum.
Mosaic coevolution is a theory in which geographic location and community ecology shape differing coevolution between strongly interacting species in multiple populations. These populations may be separated by space and/or time. Depending on the ecological conditions, the interspecific interactions may be mutualistic or antagonistic. [1]
