Island ecology is the study of island organisms and their interactions with each other and the environment. Islands account for nearly 1/6 of earth’s total land area, [ 1 ] yet the ecology of island ecosystems is vastly different from that of mainland communities.
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. In the case of an island, the area referred to as the matrix is usually the body of water surrounding it.
Since islands are less complex and more numerous than larger ecosystems, islands provide better opportunities to develop insights and perform replicable field research. Given that insular microcosms are common to all ecosystems, principles from island biogeography can be applied generally.
An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction. [2] ... an island of the Canary Islands.
The tropics are a biodiversity hotspot. Species migrate to islands and are able to create new communities and grow and change with their new environments. [19] The Equilibrium Theory of Island Biogeography, coined by MacArthur and Wilson in a 1963 article explains that biodiversity on an island is related to the size of the island. Biodiversity ...
The problem may sound small, but it was huge for aquatic life and fishers on a Tennessee river: A 10-acre island downstream of the Norris Dam was washing away. ... Norris weir dam protects ecosystem.
Easter Island, the easternmost island in Polynesia, shows evidence of ecosystem collapse, probably caused by human activity, several hundred years ago, which contributed (along with slave raiding and European diseases) to a 99% decline in the human population of the island. The island, once lushly forested, is now mostly windswept grassland.
The wide range of endemic species and the islands form a distinct ecoregion, the Bermuda subtropical conifer forests. The variety of species found both on land and in the waters surrounding Bermuda have varying positive and negative impacts on the ecosystem of the island, depending on the species.
