A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and ...
An ecosystem engineer is any species that creates, significantly modifies, maintains or destroys a habitat. These organisms can have a large impact on species richness and landscape-level heterogeneity of an area. [1] As a result, ecosystem engineers are important for maintaining the health and stability of the environment they are living in.
Ecological monitoring is the systematic collection of data relevant to the ecology of a species or habitat at repeating intervals with defined methods. [84] Long-term monitoring for environmental and ecological metrics is an important part of any successful conservation initiative.
Functional group (ecology) A functional group is merely a set of species, or collection of organisms, that share alike characteristics within a community. Ideally, the lifeforms would perform equivalent tasks based on domain forces, rather than a common ancestor or evolutionary relationship. This could potentially lead to analogous structures ...
Foundation species. In ecology, the foundation species are species that have a strong role in structuring a community. A foundation species can occupy any trophic level in a food web (i.e., they can be primary producers, herbivores or predators). The term was coined by Paul K. Dayton in 1972, [2] who applied it to certain members of marine ...
A keystone species is a species that is connected to a disproportionately large number of other species in the food-web. Keystone species have lower levels of biomass in the trophic pyramid relative to the importance of their role. The many connections that a keystone species holds means that it maintains the organization and structure of ...
A benefit of a specialist species is that because the species has a more clearly defined niche, this reduces competition from other species. On the other hand, generalist species, by their nature, cannot realize as much resources from one niche, but instead find resources from many. Because other species can also be generalists, there is more ...
Rewilding. Rewilding is a form of ecological restoration aimed at increasing biodiversity and restoring natural processes. It differs from other forms of ecological restoration in that rewilding aspires to reduce human influence on ecosystems. [1] It is also distinct from other forms of restoration in that, while it places emphasis on ...
