Intraspecific and Interspecific Agonistic Behavior in Chipmunks, TAMIAS MERRIAMI, T. OBSCURUS, and T. SPECIOSUS (Rodentia: Sciuridae)
<p>Agonistic behavior in three species of chipmunks, Tamias merriami, T. obscurus, and T. speciosus, was compared at seven locations in the San Bernardino and San Jacinto Mountains of southern California. The study was conducted during the post-breeding periods in the summers of 1983 and 1984. …

Comparative Phylogeography of Eastern Chipmunks and White -Footed Mice: Population Histories Since the Last Glacial Maximum
Finally, analyses of variation at 6 microsatellite loci among 210 P. leucopus from three sites each around three of the largest cities in Illinois recovered reduced levels of gene flow among sites separated by urban development compared to sites separated by deciduous forest habitat. Mitochondrial …

Habitat Associations and Demography of Small Mammals in 4 Forest Cover Types on Quantico Marine Corps Base, Virginia
… shrews (Blarina brevicauda), eastern chipmunks (Tamias striatus), meadow voles (Microtus pennsylvanicus), and woodland voles (Microtus pinetorum), accounted for approximately 95% of the total number of individuals captured. Overall relative abundance and species composition of small …

An observational study of ticks on the 30 Acre Lake Trail at Turnbull National Wildlife Refuge
… in humans and other mammals. Hosts (mice, chipmunks, rabbits, deer, and elk) must be in the tick’s questing range to fulfill the life cycle. The questing range depends on the life stage of the tick, vegetation, and host accessibility. Mammal densities directly affect the number of questing …

Geographic distributions and vertebrate host specificity of genetic lineages of Borrelia burgdorferi
… with only one HIA in a site with almost no mice. Chipmunks (Tamias striatus) were hosts of allele U, the only specialist. Surprisingly, while an unexpectedly large number of alleles were recovered from chipmunks, including HIAs, allele U was not found in mixed infections. These results are …

Small mammal communities on a reclaimed mountaintop mine/valley fill landscape in southern West Virginia
… and were the most common array capture. Eastern chipmunks (Tamias striatus), woodland jumping mice (Napaeozapius insignus), woodland voles (Microtus pinetorum), northern short-tailed shrews (Blarina brevicauda), and pygmy shrews (Sorex hoyi) were more common in forest treatments; Peromyscus, …

Seed Dispersal of Wild Peony (Paeonia brownii): as seed in the pouch is worth two in the pod
… seed caching results indicate that yellow pine chipmunks, deer mice, and long-eared chipmunks are potential dispersers in Jeffrey pine forest habitat and Great Basin pocket mice, Panamint kangaroo rats, and deer mice are potential dispersers in sagebrush scrub habitat. . In 2009, cache pilferage …

CLIMATE DRIVEN RANGE SHIFTS OF NORTH AMERICAN SMALL MAMMALS: SPECIES’ TRAITS AND PHYLOGENETIC INFLUENCES
… to North America: kangaroo rats, voles, chipmunks, and ground squirrels. I used species distribution modeling to develop predictions for the distributions of species under current and future climate scenarios, and quantified the differences. AIC analysis was used to compare alternative …

The effects of a silvicultural sludge application on small mammal populations and the potential of Giardia contamination in a forest ecosystem
… the abundances of deer mice, Oregon voles, and chipmunks on treatment areas relative to controls after sludge application. This was also the case for recruitment, survival, mean body weight, weight at sexual maturity, sex ratio, species diversity and spatial distribution. There was, however, a …

Diet and Feeding Ecology of the Coyotes, Black Bears, and Bobcats in Western Virginia and Preliminary Assessment of Coyote Parasites
… in open field habitat. Densities of eastern chipmunks, red-backed voles, and Peromyscus spp. were significantly higher in burned areas relative to unburned sites. Among soft mast species, blueberries comprised the largest % occurrence. I expect a generalist predator to consume deer at a …

Forest disturbance, mosquito vector ecology and La Crosse virus dynamics in southwestern Virginia
… and the LACV amplifying vertebrate host (chipmunks) were impacted by logging. This research was conducted across an experimental FCD gradient (from least to most disturbed: contiguous control, fragmented control, clearcut, and high-leave shelterwood (SW)). Using gravid traps, I found that …

Dynamics of La Crosse virus: Surveillance, Control and Effect on Vector Behavior
… triseriatus and small woodland mammals such as chipmunks and squirrels. The objectives of this study were 1) to conduct surveillance of LACV and other mosquito-borne viruses; 2) to evaluate the effect of virus infection on mosquito host-seeking and neurotransmitter levels, and 3) to determine …

The 2006 Warm Fire: effects on habitat and prey species of the northern goshawk
… showed the most sensitivity to fire, while chipmunks were evenly distributed across fire severities. Hairy woodpeckers and northern flickers, in contrast, benefitted from high-severity fire, due to increased snags, cavity nesting opportunities, and foraging. American robins and Steller's …

Infection and transmission of West Nile virus by Ochlerotatus triseriatus (Diptera: Culicidae) in the laboratory
… hosts of Oc. triseriatus, i.e. squirrels, chipmunks, rabbits, and deer, is needed to assess the possibility of a mammalian WNV transmission cycle.</p>

Habitat and Food Habits of Eutamias Minimus Scrutator in the Semi-Desert Regions of Central Washington
This paper presents the results of a food habit study on Eutamias minimus scrutator in the sagebrush-bunch grass zone of Central Washington. The major objective of the research is to relate the availability of plant species within the local habitat to the food habit biology of the species.

Small Mammal Survey of Wind Cave National Park
… white-footed mice (Peromiscus leucopus), least chipmunks (Tamias minimus), and southern red-backed voles ( Clethrionomys gappen). Rare species captured in the Park included the hispid pocket mouse ( Chaetodipus hispidus) and least shrew (Cryptotis parva). Live trapping techniques alone did not …

Subalpine Cover Ecology of Eutamias amoenus, Eutamias townsendii and other small Mammals in Huckleberry Park, Mount Rainier National Park
<p>Little work has been done on the ecology of alpine and subalpine small mammals. They are included in faunal surveys, but little is known of their habits. In the summer of 1969 this study was undertaken in subalpine Huckleberry Park, Mount Rainier National Park, to determine the species of small …
