Mesoscale Variation of Mechanisms Contributing to Stability in Rocky Shore Communities
Environmental fluctuations can generate asynchronous species' fluctuations and community stability, due to compensatory dynamics of species with different environmental tolerances. We tested this hypothesis in intertidal hard-bottom communities of north-central Chile, where a persistent upwelling centre maintains a mosaic in sea surface temperatures (SST) over 10s of kilometres along the shore....
متن کاملAbrupt community change on a rocky shore – biological mechanisms contributing to the potential formation of an alternative state
Robert T. Paine* and Alan C. Trimble Department of Biology, Box 351800, University of Washington, Seattle, WA 98195-1800, USA *Correspondence: E-mail: [email protected] Abstract The 1997/1998 El Niño initiated a major shift in the intertidal assemblage on the Washington State outer coast. A 25 year time series (1978–2003) shows stands of dominant canopy algae replaced by mussel beds. A p...
متن کاملPatterns of Variation in Levels of Hsp70 in Natural Rocky Shore Populations from Microscales to Mesoscales1
SYNOPSIS. An important step in connecting the organismal response to thermal stress to patterns of community structure is determining at what scale discernable levels of variation are manifested. The temperature signal to which organisms may potentially respond varies at many spatial scales including microhabitat, tidal height, site and latitude. A number of studies have taken physiological ass...

متن کاملUp, Down, and All Around: Scale-Dependent Spatial Variation in Rocky-Shore Communities of Fildes Peninsula, King George Island, Antarctica
Understanding the variation of biodiversity along environmental gradients and multiple spatial scales is relevant for theoretical and management purposes. Hereby, we analysed the spatial variability in diversity and structure of intertidal and subtidal macrobenthic Antarctic communities along vertical environmental stress gradients and across multiple horizontal spatial scales. Since biotic int...
