Isolation of Borrelia burgdorferi from
Neotoma fuscipes, Peromyscus maniculatus, Peromyscus boylii, and Ixodes pacificus in Oregon.
At the present study site, I found by live-trapping that wood rats,
Neotoma fuscipes, were present only in the unburned chaparral, whereas kangaroo rats, D.
Occassionally, other species such as Neotoma fuscipes, Sylvilagus spp., Eutamias townsendi, Scapanus townsendi, Rattus norvegicus, and Zapus trinotatus were taken.

Faunal nest study of the wondrat,

Extensive habitat loss has reduced the range of the riparian brush rabbit (Sylvilagus bachmani riparius) and the riparian or San Joaquin woodrat (
Neotoma fuscipes riparia) to remnant forests along the lower reaches of the San Joaquin and Stanislaus Rivers in San Joaquin County.
The dusky-footed woodrat (Neotoma fuscipes) is a medium-sized nocturnal murid rodent that occupies a variety of habitats throughout California, including chaparral (Lee, 1963), dense coniferous forests (Tevis, 1956), coastal sage-scrub (Horton and Wright, 1944), and oak woodlands (Ingles, 1995).

For example, Dusky-footed Wood-rats (
Neotoma fuscipes) have local dietary specialization even though they are considered a dietary generalist that uses a wide variety of plant communities.
Suggested reservoirs in the West include the dusky-footed woodrat (
Neotoma fuscipes), for which chronic infection has been observed, and the western gray squirrel (Sciurus griseus), which are frequently infected in nature (5,6).
Dusky-footed woodrats (
Neotoma fuscipes) were present at lower elevations and reached greatest densities in pine-cedar forests.
This implication contrasts with the role of some rodent reservoirs such as the dusky-footed wood rat (
Neotoma fuscipes) in the United States, which can remain PCR-positive for more than 1 year and act as an overwinter reservoir of infection (33,34).
Earlier we reported the impact of the prescribed burn on abundance of selected species of birds, small mammals, amphibians, and reptiles using simple correlation (Vreeland and Tietje, 2002), and for survival and abundance of dusky-footed woodrats (
Neotoma fuscipes; Lee and Tietje, 2005).
The rodent fauna in the study area included the dusky-footed woodrat (
Neotoma fuscipes), desert woodrat (N.
