Turnover Rates in Insular Biogeography: Effect of Immigration

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands. … Se mer For biogeographical purposes, an insular environment or "island" is any area of habitat suitable for a specific ecosystem, surrounded by an expanse of unsuitable habitat. While this may be a traditional island—a … Se mer Species–area relationships show the relationship between a given area and the species richness within that area. This concept comes from the theory of island biogeography, and is … Se mer The theory of island biogeography was experimentally tested by E. O. Wilson and his student Daniel Simberloff in the mangrove islands in the Florida Keys. Species richness on several small mangroves islands were surveyed. The islands were … Se mer Within a few years of the publishing of the theory, its potential application to the field of conservation biology had been realised and was being … Se mer The theory of insular biogeography proposes that the number of species found in an undisturbed insular environment ("island") is determined by immigration and extinction. … Se mer The theory can be studied through the fossils, which provide a record of life on Earth. 300 million years ago, Europe and North America lay on the equator and were covered by steamy tropical rainforests. Climate change devastated these tropical … Se mer 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). … Se mer NettetThe theory of island biogeography (MacArthur & Wilson 1963, 1967) addressed the question of how factors such as area and distance affect the total num-ber of species … Nettet10. sep. 2024 · Island biogeography is determined by three processes: immigration, evolution, and extinction. These processes are determined by the area and isolation of islands such that smaller and more isolated islands have lower numbers of species than larger and less isolated islands.

In California, the distribution of serpentine soil creates patchy insular serpentine grasslands (ISGs) that serve as important habitats for several endemic plant species and therefore merits consideration for conservation.

NettetThe MacArthur—Wilson model of island biogeography is modified to provide for this effect of immigration on extinction, which we call the rescue effect. This new model predicts that when immigration rates are high relative to extinction rates, turnover rate is directly related to the distance between an island and the source of colonizing species.
