Abstract

Vertical zonation within the intertidal results from an interaction between the physical environment and an organism's physiological limits. Bioenergetic costs of emersion are likely to vary based on an organism's vertical location in the intertidal. The present study quantified the metabolic costs of microhabitat choice in the important intertidal predator Pisaster ochraceus. Rates of oxygen consumption (VO"2) were measured at a range of ecologically relevant temperatures in both water and air. In both
