Examples of temporal variability in RVNA serological status of 20 wild big brown bats (Eptesicus fuscus) sampled 5 or more times, Fort Collins, Colorado 2001–2005.
Open circles denote seronegative, closed circles denote seropositive at date shown at the bottom of the figure (vertical lines separate years). M-A are months of May through August each year. Individual bat identification number is given at the left-hand column.

Relationship between day of the season (horizontal axis) and probability of an adult female big brown bat (Eptesicus fuscus) being seropositive for RVNA on first sampling in three different years of study.
The reference year is 2003.
Figure 4.
Probability of an adult female big brown bat (Eptesicus fuscus) transitioning from seronegative to seropositive for RVNA with the advancing season of bat activity (early April to September), conditional that the bat was seronegative on the previous sampling (see Methods).
