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.
Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. [6] Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO 2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity.
Community would be the collective dynamics amongst species and the habitat in which they live in. [6] Communities are most closely associated with habitats, which are more intimate than compared to ecosystems. Habitats signify a smaller, more specific region, while an ecosystem is a broader term that can encompass multiple habitats.
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
In scientific ecology, climax community or climatic climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is ...
A structural diagram of the open ocean plankton ecosystem model of Fasham, Ducklow & McKelvie (1990). [1]An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the real system.
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.
HERMIONE research ranges from investigation of the ecosystems' dimensions, distribution, interconnection and functioning, to understanding the potential impacts of climate change and anthropogenic disturbance. The ultimate objective is to provide stakeholders and policymakers with the scientific knowledge necessary to support deep-sea ...
