I look forward to your paper. I didn't exclude them. The edaphic variable Mathews Cultivation Intensity was included in the table above as are topo variables. My argument is that results show that monthly variables are surprisingly good among all variables, and especially much better than annual averages. It is possible that other non-climate variables could be better predictors (particularly in a marine environment). I think most studies have failed to recognize the importance of selection of variables from a wide range of possible variables. You must also take into account that most soil important variables like pH and C/N are not really available in extensive fine scaled spatial grids, and so until they are, are not available for prediction of species distributions.

Take plants as an example where most published studies only consider climatic predictors, disregarding important soil factors. See Coudun et al. (in press) in Journal of Biogeography for an illustration of the importance of soil factors (pH, C/N) to explain ecological response and geographic distribution of Acer campestre in French forests.
