abundance in different-aged forests in northwestern California.
Maximum daily temperatures during our study (21-27[degrees]C) were comparable to the thermal neutral zone of the dusky-footed woodrat (20-25[degrees]C; Carraway and Verts, 1991), and animals did not experience the prolonged drought conditions described by Kaufman and Kaufman (1994).
Dusky-footed woodrat demography and prescribed fire in a California oak woodland.
Spatial organization of dusky-footed woodrats (Neotoma fuscipes).
Odds ratios were >1 for 4 sciurids species and dusky-footed woodrats. High seroprevalence was observed in northern sites.
Highest values and ORs >1 occurred in dusky-footed woodrats, tree squirrels, and some chipmunk species (Table 1; online Technical Appendix).
Thirty-four rodents (2 dusky-footed woodrats, 5 brush mice, and 27 California mice) were captured and tested for antibody or infectious arenavirus.
The broad geographic association of WWAV with the rodent genus Neotoma suggests that WWAV is the arenavirus associated with dusky-footed woodrats in the Santa Ana Mountains.
However, the infections in the California mice could be the result of horizontal virus transmission from dusky-footed woodrats or another rodent that was not well represented in our study.
cinerea) were moderately abundant in some old Douglas-fir forests in some years; (2) that bushy-tailed woodrats were generally absent from young Douglas-fir forests; (3) that occupancy of old Douglas-fir forests was variable, suggesting local extinctions; and (4) that occupancy of early seral stages of mixed-conifer forests by dusky-footed woodrats
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).
Within the 10-m-radius circle, we recorded all pieces of large wood [greater than or equal to] m long and [greater than or equal to] 10 cm diameter at the small end, snags that were [greater than or equal to] 10 cm dbh and [greater than or equal to] 1.5 m tall, and dwellings of dusky-footed woodrats. We repeated this method on the same plots after the prescribed burn during October-December, and evaluated changes with paired sample t-tests (Zar, 1999).
