Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some ...
Beaver, Canadian lynx, bobcat, wolverine, and snowshoe hare are all keystone species in the taiga area. These species are keystone because they have learned to adapt to the cold climate of the area and are able to survive year-round. These species survive year-round in taiga by changing fur color and growing extra fur.
Not all cultural keystone species are beneficial to a community or an ecosystem, particularly when the species is considered invasive. [2] One example of this is the Australian Eucalyptus tree that is now widespread in California and is considered to be culturally important because of its aesthetic value and dietary uses.

A "keystone species" is a species that "has disproportionate importance in their community." [8] Keystone species on the great plains include the bison and the prairie dog. Many other species live on the grasslands, including deer, rabbits, mice, and many types of birds.
This has a positive effect on species richness and diversity of their habitats which results in the prairie dogs being labelled as keystone species. [17] Arthropods can also be ecosystem engineers, such as spiders, ants, and many types of larvae that create shelters out of leaves, as well as gall-inducing insects that change the shapes of ...
Paine defined the concept of a keystone species as a species that has a disproportionate effect on the community structure of an environment in relation to its total biomass. This keystone species effect forms the basis for the concept of ecological extinction. [2]
