Testing island biogeography theory with visitation rates of birds to British islands

Journal of Biogeography, 2009
AbstractAim  We consider three hypotheses – MacArthur and Wilson’s island biogeography theory (IBT), Lack’s habitat diversity idea and the ‘target effect’– that explain the pattern of decreased species richness on small and distant islands.Location  We evaluate these hypotheses using a detailed dataset on the occurrence and abundance of terrestrial ...

Contemporizing island biogeography theory with anthropogenic drivers of species richness [PDF]

Global Ecology and Biogeography, 2023
Aim: Island biogeography theory states that species richness increases with habitat diversity and decreases with isolation from source pools. However, ecological theory must incorporate effects of human activity to explain contemporary patterns of ...

A roadmap for island biology: 50 fundamental questions after 50 years of The Theory of Island Biogeography [PDF]

Journal of Biogeography, 2017
Aims: The 50th anniversary of the publication of the seminal book, The Theory of Island Biogeography, by Robert H. MacArthur and Edward O. Wilson, is a timely moment to review and identify key research foci that could advance island biology.

Island biogeography of the Anthropocene

Nature, 2014
For centuries, biogeographers have examined the factors that produce patterns of biodiversity across regions. The study of islands has proved particularly fruitful and has led to the theory that geographic area and isolation influence species ...

Fungi, leaves, and the theory of island biogeography

Microbial Ecology, 1987
Species dynamics of fungi (filamentous fungi and yeasts) on apple leaves were studied within the framework of the theory of island biogeography by following "immigration" and "extinction" patterns on individual apple leaf "islands" over time. Total fungi were censused on unmanipulated leaves collected throughout two seasons; filamentous fungi only were

A new general theory of Island Biogeography

2022
The Equilibrium Theory of Island Biogeography (ETIB) is a widely applied dynamic theory proposed to explain why islands have coherent differences in species richness. The development of the ETIB was temporarily challenged by the alternative static Theory of Ecological Impoverishment (TEI), which suggests that the number of species on an island is ...

Island Biogeography Theory and Conservation Practice

Science, 1976
The application of island biogeography theory to conservation practice is premature. Theoretically and empirically, a major conclusion of such applications—that refuges should always consist of the largest possible single area—can be incorrect under a variety of biologically feasible conditions.

Extensions of Island Biogeography Theory predict the scaling of functional trait composition with habitat area and isolation

Ecology Letters, 2017
The Theory of Island Biogeography (TIB) predicts how area and isolation influence species richness equilibrium on insular habitats. However, the TIB remains silent about functional trait composition and provides no information on the scaling of ...

A Theory of Island Biogeography for Exotic Species

The American Naturalist, 2015
The theory of island biogeography has played a pivotal role in the way ecologists view communities. However, it does not account for exotic species explicitly, which limits its use as a conservation tool. Here, I present the results of a long-term study of plant communities inhabiting an archipelago of small islands off the coast of New Zealand and ...

Habitat islands and the equilibrium theory of island biogeography: testing some predictions

Oecologia, 1988
Species-area data from a study of marsh birds are used to test five predictions generated by the equilibrium theory of island biogeography. Three predictions are supported: we found a significant species-area relationship, a non-zero level of turnover, and a variance-mean ratio of 0.5.
