Movement Patterns of Eastern Chipmunks (tamias Striatus) near Roads
Previous studies suggest that eastern chipmunks (Tamias striatus) avoid roads, but it is unclear whether vehicle traffic plays a role in this avoidance. The purpose of this study was to determine whether road avoidance in chipmunks increases with traffic. We tracked the movements of 68 chipmunks released near roads with widely varying volumes of traffic. Our results suggest that chipmunks respo...
متن کاملWest Nile Virus Viremia in Eastern Chipmunks (Tamias striatus) Sufficient for Infecting Different Mosquitoes
In eastern chipmunks (Tamias striatus) inoculated intramuscularly with 101.5 to 105.7 PFU of West Nile virus (WNV), serum titers developed sufficient to infect Aedes triseriatus (Say), Ae. vexans (Meigen), and Culex pipiens (L.). Mean titers (95% confidence interval) of 8 chipmunks were 103.9(3.3-4.5), 106.7(6.4-7.0), and 105.8(4.1-7.5) PFU/mL on days 1-3 postinoculation (p.i.) and 105.8 PFU/mL...
متن کاملFree-ranging eastern chipmunks (Tamias striatus) infected with bot fly (Cuterebra emasculator) larvae have higher resting but lower maximum metabolism
Given the ubiquity and evolutionary importance of parasites, their effect on the energy budget of mammals remains surprisingly unclear. The eastern chipmunk (Tamias striatus (L., 1758)) is a burrowing rodent that is commonly infected by cuterebrid bot fly (Cuterebra emasculator Fitch, 1856) larvae. We measured resting metabolic rate (RMR) and cold-induced VO2-max (under heliox atmosphere) in 20...
متن کاملValidation and use of hair cortisol as a measure of chronic stress in eastern chipmunks (Tamias striatus)
Stress levels of individuals are documented using glucocorticoid concentrations (including cortisol) in blood, saliva, urine or faeces, which provide information about stress hormones during a short period of time (minutes to days). In mammals, use of hair cortisol analysis allows for the assessment of prolonged stress over weeks and months and provides information on chronic stress levels with...
متن کاملDeterminants of population genetic structure in eastern Chipmunks (Tamias striatus): the role of landscape barriers and sex-biased dispersal.
Dispersal and gene flow are important processes affecting the evolutionary potential of wild populations. Assessing the importance of such patterns is thus critical, especially in contexts where environmental attributes may enhance or restrict the movements of individuals across patchy habitats. A landscape genetics approach is effective in that respect as it combines spatial and genetic data t...
