Biotic homogenization是什么意思
WebBiotic taxonomic homogenization (hereafter biotic homogenization) is the increase in taxonomic similarity across habitats or regions (i.e., lower species turnover), generally associated with the loss of rare species and persistence and/or spread of shared species (Olden and Poff 2003, Olden 2006, Smart et al. 2006).
