Odds ratios were >1 for 4 sciurids species and dusky-footed woodrats.
Highest values and ORs >1 occurred in dusky-footed woodrats, tree squirrels, and some chipmunk species (Table 1; online Technical Appendix).
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).
Antibody to an arenavirus was detected in 1 of 2 dusky-footed woodrats and 4 of 8 California mice captured at the Bear Canyon Trailhead, 1 of 11 California mice captured at El Cariso #1, and 4 of 8 California mice and none of 5 brush mice captured at El Cariso #2.
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.
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).
