This paper represented a watershed in the description of ecological relationships between species.

Also Know, how do you identify a keystone species? Thus, identifying keystone species in a given ecosystem may be formulated as: (1) estimating the impact on the different elements of an ecosystem resulting from a small change to the biomass of the species to be evaluated for its 'keystoneness'; and (2) deciding on the keystoneness of a given species as a function of

Additionally, what are some examples of a keystone species?

Some examples of keystone species include the bison, prairie dog, and otter. These are keystone species because they have great affect on their ecosystem, and without them, the ecosystem would change or suffer.

How do keystone species maintain diversity?

Such species help to maintain local biodiversity within a community either by controlling populations of other species that would otherwise dominate the community or by providing critical resources for a wide range of species. The name keystone species, coined by American zoologist Robert T.
