Experimental investigations of biological responses to changes in mean intensity and temporal variability of environmental conditions are key to anticipating effects of predicted climate change. We examined the ability of rocky shore organisms to resist increased levels of aerial expo- sure due to prolonged periods of high barometric pressure and calm sea conditions. By temporarily transplanting assemblages from the lowshore environment to mid- and high-shore habitats and vary- ing the temporal intervals between successive transplantations, we examined the effects of intensity and temporal variability of aerial exposure. Resistance was evaluated through comparisons of multi- variate and univariate response variables between transplanted cores and reference assemblages in the lowshore habitat. When differences emerged from these comparisons, we hypothesized that assemblages could shift towards those occurring under natural conditions of more severe aerial expo- sure. This was tested by comparing transplanted assemblages to those occurring naturally higher on the shore. The study was repeated twice to test for the generality of outcomes. Although individual taxa showed mixed responses varying between experimental trials that in some cases made their abundances similar to those occurring higher on the shore, whole assemblages and the number of taxa did not generally respond to experimental treatments. Present findings add to the few experi- mental investigations of the interactive effects of mean intensity and temporal variance of climatic variables, contributing to refined predictions of responses of rocky shore organisms to climate change.
