Pencil urchin respiration rates at different temperatures from four sites in the Galápagos archipelago
Abstract:
The responses of ectothermic organisms to changes in temperature can be modified by acclimatization or adaptation to local thermal conditions. Thus, the effect of global warming and the deleterious effects of extreme highs (e.g., heatwaves) on the metabolism and fitness of ectotherms can be population-specific and reduced at warmer sites. We tested the hypothesis that grazer populations at warmer sites in the Galápagos are less thermally sensitive than populations at cooler sites (i.e., potentially due to acclimatization or adaptation). We quantified the acute thermal sensitivity of four populations of the pencil sea urchin, Eucidaris galapagensis, by measuring individual oxygen consumption across a range of temperatures. Thermal performance curves were estimated for each population and compared to the local ocean temperature regime. This dataset contains the pencil urchin respiration rates at different temperatures from four sites in the Galápagos archipelago.
