Rodents are ideal model for investigating the effects of global changes on the dynamics of biodiversity changes
Rodents are indicators of local environment changes, and of environmental stress through ecotoxicological or immunological markers with implications for disease transmission. A better knowledge of rodent ecology will help at investigating human-rodents interactions (task 6). Recent attention has been paid on the potential role of other processes driven by the evolutionary history of species, which impacts both neutral and adaptive genetics and/or trade-offs between crucial biological functions.
The objectives of Task 4 are
1: to describe the pattern of rodent diversity at large scale (environmental gradients) and local scale (habitat) and the relationship with environmental changes, using genetics and morphometrics.
2: to infer mechanisms of dispersion at large scale (invasion) and local scale (habitat colonization) and the relationship with environmental changes
3: to analyze the impacts of pollutants, pesticides due to agricultural practices, on physiology of rodents, sexual size and shape dimorphism as marker of environmental impacts.
4 : to analyze the variability of rodent investment in immunity, as a marker of environmental stress and ability of resilience/susceptibility to factors that reduce biodiversity, with implications for zoonotic diseases.
