  2. Ecosystem engineer - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_engineer

    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.

    Grazing species such as plains bison, which is another keystone species, the pronghorn, and the mule deer have shown a proclivity for grazing on the same land used by prairie dogs.

    By analyzing network structures, one can determine keystone species that are of particular importance. A different class of keystone species is what are termed 'ecosystem engineers'. Certain organisms alter the environment so drastically that it affects many interactions that take place within a habitat.

    Despite all of this going on in the forest, most conservation efforts tend to focus on what are known as keystone species, like wolves. The idea is that such species bring overall benefits to the ...

  6. Ecological network - Wikipedia

    en.wikipedia.org/wiki/Ecological_network

    Ecosystem complexity was once thought to reduce stability by enabling the effects of disturbances, such as species loss or species invasion, to spread and amplify through the network. However, other characteristics of network structure have been identified that reduce the spread of indirect effects and thus enhance ecosystem stability. [ 24 ]

    en.wikipedia.org/wiki/Ecology

    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 ...

  9. Beaver dam - Wikipedia

    en.wikipedia.org/wiki/Beaver_dam

    These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem engineers. They build prolifically at night, carrying mud with their forepaws and timber between their teeth.
