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.
Species evenness is the relative number of individuals of each species in a given area. [181] Species richness [182] is the number of species present in a given area. Species diversity [183] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
All species of termites are eusocial, and it is believed that they were the first eusocial animals to evolve, sometime in the upper Jurassic period (~150 million years ago). [62] The other orders shown contain both eusocial and non-eusocial species, including many lineages where eusociality is inferred to be the ancestral state.
In the study of community ecology, competition within and between members of a species is an important biological interaction. Competition is one of many interacting biotic and abiotic factors that affect community structure, species diversity, and population dynamics (shifts in a population over time). [3]
A superorganism, or supraorganism, [1] is a group of synergetically-interacting organisms of the same species. A community of synergetically-interacting organisms of different species is called a holobiont.
African elephants call each other and respond to individual names — something that few wild animals do, according to new research published Monday. Scientists believe that animals with complex ...
Solitary life in animals is considered to be the ancestral state of living; and group living has thus evolved independently in many species of animals. [2] Therefore, species that form groups through social interaction will result in a group of individuals that gain an evolutionary advantage, such as increased protection against predators ...
This shows the kind of push-back that would ensue if animals were granted legal rights. Proposition 12 did not abolish factory farms. It merely made them less cruel, and the Supreme Court had to ...
