MacArthur and Wilson's classic work has inspired studies aimed at elucidating various facets of insular floras, such as documenting species turnover (e.g. Heatwole & Levins 1973; Abbott 1977; Nilsson & 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.

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.
