This paper reviews three of the main threats to biological diversity, such as habitat fragmentation /habitat loss, and invasion of exotic species, mainly from their evolutionary implications. Effects of habitat fragmentation/habitat loss could be addressed by looking at the synergy between demographic and genetic factors that together shape evolutionary changes or otherwise bring populations to extinction vortex. Biological invasions, in spite of their strong negative effects on biological diversity, offer an interesting scenario to study contemporary evolutionary processes.

Keywords : Biological invasions; contemporary evolution; extinction vortex; fragmentation; habitat loss.
