title: Data from: Predicting oxygen thresholds of marine taxa to improve ecological forecasts

description: 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
 Canadian Pacific coast, finding that models that used imputed values
 sometimes – but not always – improved the performance of species
 distribution models compared to models that use environmental pO2 alone.
 This modeling framework and data can support species distribution modeling
 for marine species by providing an alternative way to consider the role of
 shifting oxygen levels and temperatures on species ranges.

 Description of the data and file structure Overview This repository
 contains data collated from a meta-analysis of laboratory PCrit
 measurements on marine animal species, and survey data from
 NOAA-Fisheries, Department of Fisheries and Oceans, Canada, and the
 International Pacific Halibut Commission. Any NA represents missing data.
 ### Files and variables #### File: allpcritdata_alphia.csv

 that oxygen levels in the experimental chamber were reduced through the
 experimentalorganism'ss respiration. Controlled means that there was
 a deliberate and controlled manipulation of experimental oxygen. *

 point at which species became oxyconformers ("oxyconform"), or
 when oxygen consumption dropped below standard metabolic rate
 ("smr") * Notes: Any notes on the experimental setup * Phylum:
 Taxa phylum * Class: Taxa Class * Order: Taxa Order * Family: Taxa Family
