Hello All. In examining the literature on climatic predictor variables for predicting the distribution of mountain vegetation species, I have come across a huge range of variability in the temporal characteristics of these variables. For example, for mean temperature, I have seen studies use mean annual, mean July, mean between April and October, Degree Days, and countless other permutations. The same holds true for min and max temperatures and to a lesser extent precipitation. Lets assume that I have data summarized on the daily time-step. What is the consensus (if there is one) on the optimal temporal integration to use for montane and sub-alpine species? Along the same lines, does anyone know of papers that address this topic. Thanks a bunch. Solomon
