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. BlancoChih-Wei YuB.

Interplay between stochastic and deterministic processes in the maintenance of alternative community states in Verrucomicrobia-dominated shallow lakes. Kelp Forests versus Urchin Barrens: Rohr The Journal of animal ecology For most traits, giant eucalypt forest was similar to rainforest, while rainforest, particularly tropical rainforest, was tge different from the open vegetation.

In ecological studies in the Aleutian Islands, the presence and absence of dense sea otter populations can instigate state shifts between two alternately stable nearshore communities, one dominated by kelp and the other by sea urchins [11—13].

This study examined otter prey abundance, size, biomass, and potential energy density in remnant kelp forest and urchin-dominated communities to determine if alternate stabilit states affect prey quality. Although debated, prey quality changes have been implicated in current otter population status. The lack of clear functional differentiation from rainforest suggests that giant eucalypt forests are unstable states within the basin of attraction of rainforest.

The meaning of stability.

Significant changes in the abundance of key lewonyin 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. See our FAQ for additional information. Such states are nontransitory, persist over ecologically relevant timescales, and are therefore considered domains of stable equilibrium [2, 3].
