For GSS Losing Biodiversity chapter 7. Excerpt: Climate change may cause the extinction of 82 percent of California's native fish species, including iconic ones such as Central Valley salmon and Delta smelt, according to a new study. The peer-reviewed study by fishery experts at UC Davis created a framework to measure how vulnerable numerous species are to climate change. It assesses habitat conditions, climate change projections and temperature sensitivity for the 121 native and 50 nonnative fish species that inhabit California. It found that 82 percent of the native species are at risk of extinction in the next 100 years, largely because climate change will make water temperatures too warm. For nonnative fish, which are generally more adaptable to warm water, only 19 percent are likely to die off. ...The study is available online at http://ht.ly/lyRR8 .... http://www.sacbee.com/2013/05/30/5459758/climate-change-study-82-percent.html.
