why do siberian chipmunks tamias sibiricus (sciuridae) introduced in french forests acquired so few intestinal helminth species from native sympatric murids?a lack of newly acquired species partly explains why introduced host species have poor specific parasite diversity. the intestinal helminth community from two native murid host species, wood mice apodemus sylvaticus [murinae] (n=40), bank voles clethrionomys glareolus [arvicolinae] (n=42), and an introduced sciurid, the siberian chipmunk tamias sibiricus (n=42), dominant in the rodent communities, was studied from three woody areas in the ile-de-france region. native gastrointestinal helminth fa ...200919050922
introduced siberian chipmunks (tamias sibiricus barberi) contribute more to lyme borreliosis risk than native reservoir rodents.the variation of the composition in species of host communities can modify the risk of disease transmission. in particular, the introduction of a new host species can increase health threats by adding a new reservoir and/or by amplifying the circulation of either exotic or native pathogens. lyme borreliosis is a multi-host vector-borne disease caused by bacteria belonging to the borrelia burgdorferi sensu lato complex. it is transmitted by the bite of hard ticks, especially ixodes ricinus in eur ...201323383170
