A biocenosis (UK English, biocoenosis, also biocenose, biocoenose, biotic community, biological community, ecological community, life assemblage), coined by Karl Möbius in 1877, describes the interacting organisms living together in a habitat . [1] The use of this term has declined in the 21st сentury.
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.
Biotic interactions can vary in intensity (strength of interaction), and frequency (number of interactions in a given time). [ 31 ] [ 32 ] There are direct interactions when there is a physical contact between individuals or indirect interactions when there is no physical contact, that is, the interaction occurs with a resource, ecological ...
Biotic may refer to: Life, the condition of living organisms; Biology, the study of life; Biotic material, which is derived from living organisms; Biotic components in ecology; Biotic potential, an organism's reproductive capacity; Biotic community, all the interacting organisms living together in a specific habitat
5. With increased nutrient availability and decreased predation from zooplankton, a diverse phytoplankton community develops. 6. As the summer continues, nutrients become depleted in a predictable order: phosphorus, silica, and then nitrogen. The abundance of various phytoplankton species varies in relation to their biological need for these ...
Population, community, and physiological ecology provide many of the underlying biological mechanisms influencing ecosystems and the processes they maintain. Flowing of energy and cycling of matter at the ecosystem level are often examined in ecosystem ecology, but, as a whole, this science is defined more by subject matter than by scale.
The River continuum concept (RCC) was an attempt to construct a single framework to describe the function of temperate lotic ecosystems from the headwaters to larger rivers and relate key characteristics to changes in the biotic community (Vannote et al. 1980). [43]
A Sand County Almanac is a combination of natural history, scene painting with words, and philosophy. It is perhaps best known for the following quote, which defines Leopold's land ethic: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community.
