Scenarios of mammal invasion

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).


Global invasion threat for the twenty-first century (Early et al., 2016).

Invasive introduced 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). Furthermore, climate and land-use change will alter ecosystems worldwide and make them more sensitive to the invasions (Bellard et al., 2013).


Effect of climate and land use changes on the number of invasive species in the world biomes (Bellard et al., 2013)

Therefore we are developing new methods for predicting introduced mammals invasions and their possible impact on native mammals through the use of life history traits analysis, habitat suitability models, connectivity analysis and global change scenarios.
