Present and future distribution of alien mammals

One of the hallmarks of Anthropocene is the human mediated translocation of species outside of their native range. Because of this, the world is now largely composed of “novel ecosystems”, with unprecedented species assemblages (Hobbs et al. 2006) and new conservation strategies are required (Kareiva & Marvier 2012).

Species introduction is a leading cause of biodiversity decline (Bellard et al., 2016) 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). Mammals are also subject to particular human interests such as the pet trade, hunting and fur farming, which increase their chances of being introduced (Pfeiffer & Voeks 2008; Blackburn et al., 2017).

 

We are developing a global comprehensive database of alien mammal distribution at global scale to investigate which environmental and species factors are behind alien mammals ecological niche and range expansion and to project the possible effect of climate change on alien mammal future distribution.
