Phys.org has the story: As climate change messes with temperature and precipitation, California newts suffer by David Colgan, University of California, Los Angeles. Excerpt in italics
That’s bad news for Los Angeles’ only newt, California newt, Taricha torosa, and other newts in the Taricha genus, particularly in the southern half of the state south of Big Sur. A UCLA-led study, in the Nature journal Scientific Reports examined body condition of newts across their entire range, from San Diego to Mendocino. In the south, researchers discovered that body condition—a measure of health that compares weight to length—decreased by an average of 20% from 2008–2016.
Independent confirmation of the study comes in the form of California Governor Gavin Newtsom seeming to shrink before our eyes as he declared martial law on the pretext of coronavirus.
