1. Although behaviours can contribute to the heterogeneity in parasite load among hosts, links between consistent individual differences behaviour and parasitic infection have received little attention. We investigated role of host activity exploration on hard tick infestations marked individuals a population Siberian chipmunks Tamias sibiricus introduced suburban French forest over 3 years. 2. Individual activity-exploration profiles were assessed from 106 hole-board tests 73 individuals,...
The transport of nutrients by migratory animals across ecosystem boundaries can significantly enrich recipient food webs, thereby shaping the ecosystems’ structure and function. To illustrate potential role islands in enabling transfer matter to be gauged, we investigated influence seabirds on nitrogen input islands. Basing our study four widely differing terms their biogeography ecological characteristics, sampled at different spatial temporal intervals, analyzed isotopic values main...
The variation of the composition in species host communities can modify risk disease transmission. In particular, introduction a new increase health threats by adding reservoir and/or amplifying circulation either exotic or native pathogens. Lyme borreliosis is multi-host vector-borne caused bacteria belonging to Borrelia burgdorferi sensu lato complex. It transmitted bite hard ticks, especially Ixodes ricinus Europe. Previous studies showed that Siberian chipmunk, Tamias sibiricus barberi,...
Over the past decade, it has been recognized that in many animal species, individuals present consistent behavioral differences across time and/or contexts, thus defining personality traits. A general relationship seems to exist between and fitness wild populations, which raises question as how variation is maintained presence of selection. Fluctuating selection associated with a heterogeneous environment could contribute maintaining variation, but its populations rarely tested. In this...
Brown rats are one of the most widespread urban species worldwide. Despite nuisances they induce and their potential role as a zoonotic reservoir, knowledge on rat populations remains scarce. The main purpose this study was to characterize an brown population from Chanteraines park (Hauts-de-Seine, France), with regards haematology, genetics, immunogenic diversity, resistance anticoagulant rodenticides, community parasites. Haematological parameters were measured. Population genetics...
Introduced hosts populations may benefit of an "enemy release" through impoverishment parasite communities made both few imported species and acquired local ones. Moreover, closely related competing native can be affected by acquiring introduced taxa (spillover) increased transmission risk parasites (spillback). We determined the macroparasite fauna invasive grey squirrels (Sciurus carolinensis) in Italy to detect any diversity loss, introduction novel or acquisition ones, analysed variation...
Host-specificity is an intrinsic feature of many bacterial pathogens, resulting from a long history co-adaptation between bacteria and their hosts. Alpha-proteobacteria belonging to the genus Bartonella infect erythrocytes wide range mammal orders, including rodents. In this study, we performed genetic analysis colonizing rodent community dominated by bank voles (Myodes glareolus) wood mice (Apodemus sylvaticus) in French suburban forest evaluate diversity, capacity recombine level host...
Abstract The ability of invasive mammals to adjust their diet in response new or variable resources is often proposed explain invasion success on islands with differing environmental conditions, especially strong spatiotemporal changes the nature and abundance resources. In this study, we investigated how habitat heterogeneity seasonal fluctuation resource quality affect dietary breadth plasticity an island‐invasive rodent, black rat Rattus rattus , a small Mediterranean island. We tested...
By accompanying human travels since prehistorical times, the house mouse dispersed widely throughout world, and colonized many islands. The origin of travellers determined phylogenetic source insular mice, which encountered diverse ecological environmental conditions on various Insular mice are thus an exceptional model to disentangle relative role phylogeny, ecology climate in evolution. Molar shape is known vary according phylogeny respond adaptation. Using for first time a...
Eurasian red squirrels (Sciurus vulgaris) in the British Isles are most recently discovered animal reservoir for leprosy bacteria Mycobacterium leprae and lepromatosis. Initial data suggest that prevalence of infection is variable often low different squirrel populations. Nothing known about presence bacilli other wild species despite two others (Siberian chipmunk [Tamias sibiricus], Thirteen-lined ground [Ictidomys tridecemlineatus]) having been reported to be susceptible experimental with...
Whether urban parks can maintain viable and self-sustaining populations over the long term is questionable. In highly urbanized landscapes, could play a role in biodiversity conservation by providing habitat resources to native species. However, inhabiting are usually small isolated, leading increased demographic stochasticity genetic drift, with expected negative consequences on their viability. Here, we investigated European red squirrel population located an park close Paris, France (Parc...
Invasions and anthropogenic disturbances challenge species with rapid environmental changes. Understanding how organisms respond to these changes is of major concern for the future biodiversity. The house mouse on a Sub-Antarctic island (Guillou Island, Kerguelen Archipelago) had face such challenges twice: first when invading two centuries ago; nowadays coping an in-depth remodeling its habitat due cohort Morphometric biomechanical results show that initial invasion triggered evolution jaw...
Integrative taxonomy, a multi-disciplinary approach adding modern techniques to traditional morphology-based methods (e.g. molecular and morphological criteria), can play an important role in bioinvasion research identify introduced taxa, discover pathways of introduction inform authorities control prevent future introductions. The present study is the first on populations Callosciurus, Asiatic tree squirrels, known as potentially invasive species Europe (Italy, Belgium France). We combined...
Adaptation to new environments is a key feature in evolution promoting divergence morphological structures under selection. The house mouse (Mus musculus domesticus) introduced on the Sub-Antarctic Guillou Island (Kerguelen Archipelago) had and still has face environmental conditions that likely shaped pattern pace of its insular evolution. Since arrival island, probably not more than two centuries ago, ecological dramatically differed from those available their Western European commensal...
Abstract Studies on the role of introduced rabbits, Oryctolagus cuniculus, islands have mainly focused their negative impacts vegetation. However, little attention has been paid to influence vertebrate communities. On Ile Verte (148 ha) in sub-Antarctic Kerguelen Archipelago, rabbits are only mammal that introduced. The long-term consequences eradication 1992 both native, burrowing seabird prey populations and predator, brown skua Catharacta skua, were investigated between 1991 2005....
