PMID:29232397ĭistribution and prevalence of vector-borne diseases in California chipmunks ( Tamias spp.). Though more data are needed to thoroughly understand the roles that different chipmunk species play in disease transmission, our findings suggest that some chipmunk species may be more important to the maintenance of vector-borne diseases than others within each geographic area. pestis infection was found only in the western Sierra—in a yellow-pine (T. was found in the Northern Coastal region (Del Norte, Humboldt and Mendocino counties) and in the northern and western Sierra in several species of chipmunks. speciosus) chipmunks in the western Sierra. was detected in 2% (6/297) of redwood chipmunks in Mendocino county and 10% (1/10) of both least (T. burgdorferi most common (37.5%, 27/72) in redwood chipmunks (T. Anaplasma phagocytophilum was most common (40.0%, 2/5) in Sonoma chipmunks (T. merriami) were PCR-positive for at least one of the pathogens. DNA of all five pathogens was found and all chipmunks except Merriam’s chipmunk (T. phagocytophilum, RF Borrelia spp., Borrelia burgdorferi, and SFG Rickettsia species.
We surveyed over 700 individuals from nine species of chipmunks throughout California for exposure to and infection by Y. Chipmunk species are often not differentiated by public health workers, yet different species utilize different ecological niches and may have intrinsically different capacities for maintaining vector-borne pathogens and infecting vectors. Chipmunks host zoonotic pathogens including Yersinia pestis, Anaplasma phagocytophilum, relapsing fever (RF) Borrelia spp., Borrelia burgdorferi, and spotted fever group (SFG) Rickettsia species. Stephenson, Nicole Foley, Janet E.Ĭalifornia, with 13 chipmunk ( Tamias) species, has more than any other state or country, occupying habitats ranging from chaparral to the high peaks of the Sierra Nevada. Results for 21 chipmunks showed that prescribed fire had little discernable.ĭistribution and prevalence of vector-borne diseases in California chipmunks ( Tamias spp.) We used radiotelemetry to examine the effects of spring prescribed fire for preharvest oak (Quercus spp.) shelterwood management on eastern chipmunk ( Tamias striatus) home-range attributes and burrow use on the Fernow Experimental Forest in the central Appalachian Mountains of West Virginia. Response of eastern chipmunks to single application spring prescribed fires on the Fernow Experimental ForestĮ.L. Fine scale movements of chipmunks were followed with tracking spools and the percentage of each movement path directly along coarse woody debris was recorded. We investigated relationships between canopy closure, shrub cover and the use of coarse woody debris as a travel path by eastern chipmunks ( Tamias striatus) in the north central United States.
