Short-tailed shrews, white-footed mice, and eastern chipmunks
had mean levels of reservoir competence >10% (Figure 1).
Cicadas were less common in the diet of the opossum (Didelphis virginiana), white-footed mouse, eastern mole (Scalopus aquaticus) and eastern chipmunk
Several species, including red squirrels, eastern chipmunks
, meadow jumping mice (Zapus hudsonius), and white-footed mice were never captured in pitfalls, whereas smokey shrews (Sorex fumeus) were only captured in this trap type.
Westward range extension of the eastern chipmunk
, Tamias striatus (Rodentia: Sciuridae), in central Oklahoma.
This finding is noteworthy because the eastern chipmunk
is ubiquitous throughout forested, rural, and suburban areas of southeastern Canada, and in the eastern United States, with the exception of the eastern parts of North and South Carolina, Georgia, and most of Florida.

2008) observed that eastern chipmunks
(Tamias striatus) altered their foraging in response to the alarm calls of Tufted Titmice (Baeolophus bicolor), but not to the calls of an actual predator, the Broad-winged Hawk (Buteo platypterus).
The increasing species-white-footed mice, southern flying squirrels, eastern chipmunks
and common opossums-all are southern species, while the declining species-woodland deer mice, southern red-backed voles, northern flying squirrels, woodland jumping mice, and least chipmunks-are all northern species.
The chipmunk group comprised eastern chipmunks
(Tamias striatus), and the squirrel group included red squirrels (Tamiasciurus hudsonicus) and eastern gray squirrels (Sciurus carolinenesis).
The emphasis of this research is on the effect temperature has on metabolic responses in a population of eastern chipmunks
(Tamias striatas) from North Dakota.
Kevin Rowe and Ken Paige, biologists at the University of Illinois at Urbana-Champaign, used DNA (chemical that carries hereditary information) samples to trace the ancestors of 244 eastern chipmunks
, Tamias striatus (tuh-MY-us stree-AT-us).
Researchers tallied the mutations in mitochondrial DNA extracted from small tissue samples from 244 eastern chipmunks
, Tamias striatus, captured at 25 sites in Wisconsin, Illinois, Indiana, and Michigan.
Blood from two of three white-footed mice and from the two eastern chipmunks
, Tamias striatus, captured in the yards of the patients, produced infections in injected hamsters.
