    The Vulnerability of California Amphibian Species to Climate Change by Ben-Zeev, Rayna

    Amphibians are declining on a global scale, faster than any other taxonomic group. Although I am still unsure of the causes of many local declines, I have evidence that on a larger scale temperature and precipitation changes caused by climate change directly relate to broader amphibian disappearances. I aim to use past temperature and precipitation trends and amphibian distributions in California to predict future amphibian distributions. I use the Biomod2 package in R, along with CMIP5 climate layers and emissions scenarios to correlate amphibian distributions to climate, and predict a range of future possibilities for amphibians under different carbon emission scenarios. I hope to identify which species are most in danger of extirpation to hopefully direct future management initiatives to these species.
