Does the biogeographic origin of species matter? Ecological effects of native and non-native species and the use of origin to guide management

Abstract

The introduction and success of non-native species are both a consequence and a cause of rapid global change. Humans have created novel ecosystems through environmental modification and mass movements of organisms around the planet. It has been argued that species biogeographic origin cannot explain or predict ecological impacts and the origin of a species should not influence ecosystem management. This rejection of 'origin' is overly simplistic. Origin effects can arise through biased sampling of the types of species transported, the environmental and evolutionary context of their source environments and the communities and environments to which they are introduced. Differences in co-evolut..
