What are the theories of biodiversity?
Biodiversity theories can inform important conservation actions such as assessments of species richness and extinction or habitat loss and fragmentation. Popular examples of biodiversity theories are niche theory and island biogeography theory, whereas neutral theory is less known.
What is neutral theory in community ecology?
Neutral theory predicts that species have perfectly overlapping niches — at the other extreme would be species with unique, non-overlapping niches. Real communities, of course, likely represent neither of these extremes but are somewhere in the middle (Figure 1).
Who proposed the theory of island biogeography?
patch dynamics. …the 1970s, and with the theory of island biogeography, developed by American ecologist Robert MacArthur and American biologist E.O. Wilson in the 1960s.

What is a neutral process?
Neutral processes predicate that all species are identical in their demographic rates (birth, death, dispersal and speciation rates) and exclusion processes are completely random [6].
Who developed neutral theory?
biologist Motoo Kimura
The theory was introduced by the Japanese biologist Motoo Kimura in 1968, and independently by two American biologists Jack Lester King and Thomas Hughes Jukes in 1969, and described in detail by Kimura in his 1983 monograph The Neutral Theory of Molecular Evolution.
What is the theory of island biodiversity?
The theory of island biogeography predicts that the species richness observed on an island is the result of the interplay between three fundamental processes — extinction, colonization (the dispersal and establishment of species from the continental landmass to an island) and speciation (the generation of new species) …
What is neutral model?
The neutral model posits that random variation in extinction and speciation events, coupled with limited dispersal, can account for many community properties, including the relative abundance distribution.
