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.
The study is part of a larger effort to try to understand how climate change will affect amphibians across the state, including California and Pacific tree frogs and western toads.
