Ecological niche. The flightless dung beetle occupies an ecological niche: exploiting animal droppings as a food source. In ecology, a niche is the match of a species to a specific environmental condition. [1][2] It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when ...
For example, the dynamic history of the planetary atmosphere's CO 2 and O 2 composition has been affected by the biogenic flux of gases coming from respiration and photosynthesis, with levels fluctuating over time in relation to the ecology and evolution of plants and animals. [46] Ecological theory has also been used to explain self-emergent ...
Habitat can be defined as the natural environment of an organism, the type of place in which it is natural for it to live and grow. [4][5] It is similar in meaning to a biotope; an area of uniform environmental conditions associated with a particular community of plants and animals.
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.
Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis. Competition between members of the same species is called intraspecific competition.
Canopy cover surrounding Madison, Wisconsin. Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems. This is done within a variety of landscape scales, development spatial patterns, and organizational levels of research and policy. [ 1 ][ 2 ][ 3 ...
Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions. The rule derives from the relationship between size in linear dimensions meaning that both ...
In ecology, an ideal free distribution (IFD) is a theoretical way in which a population ' s individuals distribute themselves among several patches of resources within their environment, in order to minimize resource competition and maximize fitness. [1][2] The theory states that the number of individual animals that will aggregate in various ...
