Project
The project will implement cutting edge research methodology in different fields (genetics, genomics, biochemistry, bioinformatics, GPS tracking and parasitology) and combine them to draw a detailed picture of translocation history for three ungulate species. Aoudad and European mouflon are introduced species in Mediterranean Europe, while wild boar recently established new populations on some islands through natural colonization or illegal translocations for hunting purposes. By integrating information on neutral and fitness-related traits, we will develop a protocol which will provide a comprehensive way to assess the status of non native populations and possible influence of hunting related activities to their expansion
