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.
This allows the individuals within a group to more effectively identify predators, allowing these individuals to flee or adopt postures to alert the predators that their presence is known. An example can be seen in a study conducted by Siegfried and Underhill (1975) [ 16 ] on laughing doves , in which large groups react to a mock-predator much ...
These communities are described as working like one unit, meaning that every species plays an important part in the overall well-being of the ecosystem in which the community resides; much like the organelles within a cell, or even the cells making up one organism. Holistic communities have diffused boundaries and an independent species range.
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]
Austroplatypus incompertus is a species of ambrosia beetle native to Australia, and is the first beetle (order Coleoptera) to be recognized as eusocial. [29] [13] This species forms colonies in which a single female is fertilized, and is protected by many unfertilized females, which serve as workers excavating tunnels in trees. This species has ...
Alpha guild is specifically related to species that share a resource used within the same community. [10] Species in an alpha guild do not typically coexist in the same area, as the competitive exclusion principle prevents this. If species are grouped into an alpha guild together one of them will need to change the way they use this resource or ...
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. Metacommunity ecology combines the ...
This mechanism can be relied to both within a species or social group and within species systems. It can also be applied to a multi-partner system, in which the owner of a resource has the power to choose its co-operation partner. This model can be applied in natural systems (examples exist in the world of apes, cleaner fish, and more).
