This paper came out recently - a guide to boosted regression trees for
ecologists. Great potential for modelling species distributions from
environmental data I think.

Well written (even I can understand it) and code for R is given with
tutorials. Example for freshwater fish given. The method's non-linear. It
doesn't produce nice smooth curves, but that seems to be it's strength as no
prior assumptions are made about how the species should respond. I haven't
tried it yet. Interested to hear what sort of results people get.
