Estimates and 95% confidence intervals for detection probability (the probability of a PCRpositive result, given an individual is infected with ranavirus) for two tissue sample types (lethal liver sample and nonlethal tail samples) from site occurrence (gray bars) and multiscale (white bars) analyses of ranavirus occurrence at 22 wetlands in the Patuxent Research Refuge (Laurel, Maryland, USA). Ranavirus detection estimates are shown for both spotted salamanders (Ambystoma maculatum, light gray) and wood frogs (Lithobates sylvaticus, dark gray). Estimates shown are from the best-supported (i.e., lowest Akaike's information criterion adjusted for small sample sizes) site occurrence (gray) and multiscale (white) occupancy models.
