Predicting oxygen thresholds of marine taxa to improve ecological forecasts

Species’ ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory-derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six phyla, and fit a hierarchical model based on taxonomy to impute threshold values for all based on taxonomy, body size, and environmental temperature. As expected, pcrit increased with increasing temperature and body size, and these temperature- and body size effects were broadly similar among species. Generally, variation in pcrit measurements was estimated to be most pronounced at the taxonomic family and species level, although the partitioning of variance was relatively imprecise. We demonstrate application of these estimates for species distribution modeling of six groundfish species that reside in the coastal waters of the U.S. and Cana..., , # Data from: Predicting oxygen thresholds of marine taxa to improve ecological forecasts
