Description:
Crimmins et al. (Reports, 21 January 2011, p. 324) attributed an apparent downward elevational shift of California plant species to a precipitation-induced decline in climatic water deficit. We show that the authors miscalculated deficit, that the apparent decline in species' elevations is likely a consequence of geographic biases, and that unlike temperature changes, precipitation changes should not be expected to cause coordinated directional shifts in species' elevations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephenson, Nathan L -- Das, Adrian J -- New York, N.Y. -- Science. 2011 Oct 14;334(6053):177; author reply 177. doi: 10.1126/science.1205740.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉US Geological Survey, Western Ecological Research Center, Three Rivers, CA 93271, USA. nstephenson@usgs.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21998371" target="_blank"〉PubMed〈/a〉
