Insular biogeography [1] 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.
Oceanic islands arise due to volcanic activity or reef growth, and usually subside over time due to erosion and changing sea levels. [1] When islands emerge, they undergo the process of ecological succession as species colonize the island (see theory of island biogeography). New species cannot immigrate via land, and instead must arrive via air ...
The Theory of Island Biogeography is a 1967 book by the ecologist Robert MacArthur and the biologist Edward O. Wilson. [1] It is widely regarded as a seminal work in island biogeography and ecology. The Princeton University Press reprinted the book in 2001 as a part of the "Princeton Landmarks in Biology" series. [1]
Frank W. Preston, an early investigator of the theory of the species–area relationship, divided it into two types: samples (a census of a contiguous habitat that grows in the census area, also called "mainland" species–area relationships), and isolates (a census of discontiguous habitats, such as islands, also called "island" species–area ...
MacArthur was a professor at the University of Pennsylvania, 1958–65, and professor of biology at Princeton University, 1965–72.He played an important role in the development of niche partitioning, and with E.O. Wilson he co-authored The Theory of Island Biogeography (1967), a work which changed the field of biogeography, drove community ecology and led to the development of modern ...
The terminology of r/K-selection was coined by the ecologists Robert MacArthur and E. O. Wilson in 1967 [2] based on their work on island biogeography; [3] although the concept of the evolution of life history strategies has a longer history [4] (see e.g. plant strategies).
On Tuesday's night episode of Jeopardy! there was both a Rhode Islander competing and a question made for a Rhode Islander to get. In the category, "those who celebrate" the clue for $1,200 was:
Garganornis ballmanni, a very large fossil goose from the Gargano and Scontrone islands of the Late Miocene. Foster's rule, also known as the island rule or the island effect, is an ecogeographical rule in evolutionary biology stating that members of a species get smaller or bigger depending on the resources available in the environment.
