Invasion ecology, present and future distribution of alien mammals

Species introduction is a leading cause of biodiversity decline and predicting the alien species invasion is one of the most important challenges in conservation biology today (Bellard et al., 2013).

Alien mammals are known to be a particularly important driver of loss and homogenisation in biodiversity (Courchamp et al. 2003) and of alteration to ecosystem processes (Ehrenfeld 2010).

Using the IUCN range mapping method, we are developing a global comprehensive database of alien mammal distribution at global scale, also containing information about species invasion stage, pathways, methods and date of introduction.

Using this comprehensive data source, we are investigating alien mammals niche dynamics and factors behind both alien niche and range expansion. Furthermore, we are projecting the possible effect of climate change on alien mammal distribution under different scenarios.
