  • Analysis of climate paths reveals potential limitations on species range shifts 

    Early, Regan; Sax, Dov F. (Wiley, 2011)
    Forecasts of species endangerment under climate change usually ignore the processes by which species ranges shift. By analysing the 'climate paths' that range shifts might follow, and two key range-shift processes--dispersal ...
