Personality, space use and tick load in an introduced population of Siberian chipmunks Tamias sibiricus.
The results show that host personality-related patterns in space use can lead to a non-random parasite distribution among hosts.

The results suggest that mice responded to the recent changes in food resources, possibly with a part of plastic variation for the mandible prone to bone remodelling, that is a probable key of the success of such an invasive rodent facing pronounced shifts inFood resources exploitation under a changing environment.

Morphometric and biomechanical results show that the initial invasion triggered the evolution of a jaw shape adapted to the local food resources, and a complex response integrating feeding behaviour, investment in feeding structure, and degree of mineralization may provide the mice with a better tool to benefit of wider resources utilization and or better cope with intra-specific competition in a changing habitat.
Co-infection of Borrelia afzelii and Bartonella spp. in bank voles from a suburban forest.
Mapping human risk of infection with Borrelia burgdorferi sensu lato, the agent of Lyme borreliosis, in a periurban forest in France.

Why do Siberian chipmunks Tamias sibiricus (Sciuridae) introduced in French forests acquired so few intestinal helminth species from native sympatric Murids?
The developmental ability of helminth according to host phylogenetic relatedness was the main driving force explaining the species composition of theHelminth community between these sympatric native and introduced hosts.
Population genetics, community of parasites, and resistance to rodenticides in an urban brown rat (Rattus norvegicus) population
Parasitological results showed that co-infection is more a rule than an exception and the presence of several potential zoonotic pathogens in this urban rat population raised its role in the maintenance and spread of these pathogens.
Seabird Modulations of Isotopic Nitrogen on Islands
It is demonstrated that seabird-derived nutrients not only spread across the terrestrial ecosystems and trophic webs, but also modulate their isotopic values locally and temporally on these islands, demonstrating the wealth of experimental possibilities in insular ecosystems.
