Niche Dynamics of Alien Plant Species in Mediterranean Europe

Global Change Biology, Volume 31, Issue 8, August 2025.
In this study, we analyzed some of the most widespread alien plant species in Mediterranean Europe to understand how functional traits and species characteristics influence niche shifts, and how these, in turn, affect invasion success. We found that a species' biogeographic origin, dispersal distance, functional traits, and intraspecific trait ...

Effects of invasion by Tradescantia zebrina Heynh. on tree species regeneration in a secondary Atlantic Forest fragment, in Londrina (PR) [PDF]

Biotemas, 2013
Currently considered as one of the major causes of the loss of biodiversity on the planet, invasive alien species cause serious problems to natural ecosystems, leading many native species to become locally extinct.
