The two types of giant eucalypt forests also exhibited greater overall functional similarity to each other than to any of the open vegetation types. LabaughNed H. This paper has been referenced on Twitter 3 times over the past 90 days. Rohr The Journal of animal ecology McKennaJames W. Citation Statistics Citations 0 10 20 ’74 ’84 ’95 ’06 ‘ This study examined otter prey abundance, size, biomass, and potential energy density in remnant kelp forest and urchin-dominated communities to determine if alternate stable states affect prey quality.

Such states are nontransitory, persist over ecologically relevant timescales, and are therefore considered domains of stable equilibrium [2, 3]. Although multiple stable states can exist simultaneously, communities typically alternate from one stable state to another, a shift often conveyed by a large perturbation applied directly to the state variables e.

Findings suggest that although urchin barrens provide more abundant urchin prey, individual urchins are smaller and provide lower biomass and potential energy density compared to kelp forests.

In multivariate analyses, tropical and temperate rainforest diverged meanjng, and both segregated from open vegetation. We measured functional traits of trees and shrubs across tropical and temperate rainforest — open vegetation transitions in Australia, with giant eucalypt forests situated between these vegetation types.

For most traits, giant eucalypt forest was similar to rainforest, while rainforest, particularly tropical rainforest, was significantly different from the open vegetation.

Furthermore, the giant eucalypt forests overlapped in function with their respective maning. Interplay between stochastic and deterministic processes in the maintenance of alternative community states in Verrucomicrobia-dominated shallow lakes.

Significant changes in the abundance of key species are widely cited as evidence of phase shifts [5, 6] but see [7] and have been documented both experimentally [8] and empirically [9, 10] in coastal marine ecosystems.

Introduction Natural communities can exist at multiple stable points in time or space [1]. We analysed a set of functional traits: See our FAQ for additional information. The lack of clear functional differentiation from rainforest suggests that giant eucalypt forests are unstable states within the basin of attraction of rainforest. JordanDavid M.
