keystone species
Keystone species are the animal species controlling the ecosystem functioning. They play an important role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and number of various other species in the community.
Edge species refers to animals that are Evolutionarily Distinct and Globally Endangered (EDGE). These species are considered to be one of a kind.
Pioneer species are hardy species which are the first to colonize previously biodiverse steady-state ecosystems.
Umbrella species are species selected for making conservation-related decisions, typically because protecting these species indirectly protects the many other species that make up the ecological community of its habitat.
