Spatial Scaling in Model Plant Communities
Tommaso Zillio, Igor Volkov, Jayanth R. Banavar +2
We present an analytically tractable variant of the voter model that provides a quantitatively accurate description of beta-diversity (two-point correlation function) in two tropic…
Bacteriophage-mediated competition in Bordetella bacteria
Jaewook Joo, Michelle Gunny, Marisa Cases +3
Apparent competition between species is believed to be one of the principle driving forces that structure ecological communities, although the precise mecha nisms have yet to be ch…

Igor Volkov, Jayanth R. Banavar, Stephen P. Hubbell +1
The theory of island biogeography[1] asserts that an island or a local community approaches an equilibrium species richness as a result of the interplay between the immigration of…
Organization of Ecosystems in the Vicinity of a Novel Phase Transition
Igor Volkov, Jayanth R. Banavar, Amos Maritan
It is shown that an ecosystem in equilibrium is generally organized in a state which is poised in the vicinity of a novel phase transition.
