Data from: Extinction risk in extant marine species integrating paleontological and biodistributional data

Extinction risk assessments of marine invertebrate species remain scarce,
which hinders effective management of marine biodiversity in the face of
anthropogenic impacts. In order to close this information gap, we
developed a metric of relative extinction risk that combines
paleontological data, in the form of extinction rates calculated from the
fossil record, with two known correlates of risk in the modern day:
geographic range size and realized thermal niche. We test the performance
of this metric - PERIL (Paleontological Extinction Risk In Lineages) -
using survivorship analyses of Pliocene bivalve faunas from California and
New Zealand, and then use it to identify present-day hotspots of
extinction vulnerability for extant shallow-marine Bivalvia. Areas of the
ocean where concentrations of bivalve species with higher PERIL scores
overlap with high levels of climatic or anthropogenic stressors should be
considered of most immediate concern for conservation and for management.
