Ecological theory of alternative stable communities suggests the switch between different species assemblages occurs when environmental conditions alter species composition so that it crosses a critical threshold and enters a different basin of attrac . . .

Mussel beds and rockweed stands (fucoid algae) have been shown to be alternative states on rocky intertidal shores in New England, and here the hypothesis that variation in recruitment provides opportunity for the development of alternative community . . .

Long-lived species of large size can play critical roles as ecosystem engineers but the demography of early life stages is poorly known for many such species. For example, the fucoid alga, Ascophyllum nodosum, serves as the foundation species for many . . .

Small changes in environmental conditions can unexpectedly tip an ecosystem from one community type to another, and these often irreversible shifts have been observed in semi-arid grasslands, freshwater lakes and ponds, coral reefs, and kelp forests. . . .

Sheltered rocky bays in the Gulf of Maine support communities usually dominated either by the fucoid rockweed Ascophyllum nodosum or the mussel Mytilus edulis. In order to test whether clearing size determines the subsequent pattern of recruitment by . . .

Dispersal of propagules of marine benthic species may contribute to variation in the structure and dynamics of populations. Ascophyllum nodosum dominates the mid-intertidal zone of sheltered rocky shores in the north-west Atlantic, and populations oft . . .

It has been hypothesized that rockweed stands and mussel beds in sheltered bays in the Gulf of Maine, USA, are alternative community states. As a test of this hypothesis, experimental clearings of different sizes were established in stands of the rock . . .

Experimental clearings in macroalgal (Ascophyllum nodosum) stands were made in 1996 to determine if mussel beds and macroalgal stands on protected intertidal shores in New England represent alternative community states. Uncleared control plots and fou . . .
