Comments on Brodie and Post: Climate‐driven declines in wolverine populations: causal connection or spurious correlation?
Abstract The recent paper by Brodie and Post (“Nonlinear responses of wolverine populations to declining winter snowpack”, Popul Ecol 52:279–287, 2010 ) reports conclusions that are unsupportable, in our opinion, due to both mis‐interpretations of current knowledge regarding the wolverine's ( G...
