Description:
Hirota et al. (Reports, 14 October 2011, p. 232) used spatial data to show that grasslands, savannas, and forests represent opposing stable states. Reanalyzing their data and drawing from temporal studies, we argue that spatial analyses underestimate the bistability of grasslands and savannas due to limitations of substituting space for time. We propose that temporal and spatial data are needed to predict critical transitions between grasslands and savannas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ratajczak, Zak -- Nippert, Jesse B -- New York, N.Y. -- Science. 2012 May 4;336(6081):541; author reply 541. doi: 10.1126/science.1219346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, Kansas State University, 116 Ackert Hall, Manhattan, KS 66506, USA. zarata@ksu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556235" target="_blank"〉PubMed〈/a〉
