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 ...
Many species fall somewhere between generalist and specialist on the generalist-specialist range. Such species generally exhibit moderate environmental specialization, being neither pure generalists nor pure specialists, resulting in fluid changes that must be evaluated when categorizing species.
Some plants and animals, called specialists, need specific habitats and surroundings to survive, such as the spotted owl, which lives specifically in old growth forests. Other plants and animals, called generalists, are not as particular and can survive in a range of conditions, for example the dandelion. [79]
Island foxes are among the species unique to the Channel Islands. When you think of California, you may think of places like Hollywood, Beverly Hills, Venice Beach, Silicon Valley, Napa Valley or ...
The Channel Island fox is native to six of the eight Channel Islands of California. There are six subspecies of the fox, each unique to the island it lives on. More than 2000 species of plants and animals can be found within the Channel Islands National Park, which consists of five of the eight islands that compromise the Channel Islands.

There are more than 30 wildflower species that are endemic to the pools in this ecoregion, including Orcuttia californica grass. [7] One subspecies of meadow-foam, Limnanthes alba ssp. parishii is only found in the ephemeral wetlands of the Laguna Mountains (and also 800 mi or 1,300 km away in the Klamath Mountains).

The theory of island biogeography was originally used to study oceanic islands, but those concepts can be extrapolated to other areas of study. Island species dynamics give information about how species move and interact within Island Like Systems (ILS). Rather than an actual island, ILS are primarily defined by their isolation within an ecosystem.
