Contrasting alien effects on native diversity along biotic and abiotic gradients in an arid protected area

Abstract Alien impact on native diversity could be a function of both the relatedness of alien species to native community and resources availability. Here, we investigated whether alien plants expand or decrease the functional and phylogenetic space of native plant communities, and how this is affe...
