Our mammalian community database contains data for 1000 mammalian communities (sorry, no bat data). For 940 of those communities, we have species-level abundance data (the remaining 60 contain only species lists). For each community, we even have location information (as best as we can determine from the original publication). Go check it out - better yet, go do something cool with it!
Yesterday, Glenda Yenni successfully defended her M.S. in Statistics! Her thesis was titled: "Resource-driven energy changes in a Desert Rodent Community". In it, Glenda used her M.S. training to examine the Portal rodent data to show how using Bayesian Heirarchal modelling can contribute to our ability to understand complex interactions in ecological systems. Go, Glenda!!!
