Distribution and dispersal of invasive species redefining biogeography in Anthropocene


In a recent study, data on native and invasive ranges of terrestrial gastropod species was used to analyse dissimilarities in species composition among 56 globally distributed regions. it was found that native ranges confirm the traditional biogeographic realms, reflecting natural dispersal limitations. however the distribution of introduced gastropod species are primarily explained by prevailing climate and, to a smaller extent, by distance and trade relationships. This study underlines the importance of understanding the spatial characteristics of species dispersal and distribution and suggests that climate and to some extent socio-economic relationships will define biogeography in an era of global change.Read more here.
