Abstract

We surveyed 14 communities of mesopredators in the Ozark Highlands of southern Missouri to examine the effect of landscape and surveying efforts on probability of detection of raccoons (Procyon lotor) and Virginia opossums (Didelphis virginiana). Virginia opossums had a higher probability of detection than raccoons. Mean size of forested patches had a negative effect on probability of detection, suggesting that the hypothesis that abundance of mesopredators increases in small patches of forest is an artifact of sampling. We suggest that it is important for researchers to include probability of detection when analyzing data from surveys of mesopredators.

Muestreamos 14 comunidades de depredadores medianos en las Ozark Highlands del sur de Missouri para examinar el efecto de factores de paisaje y esfuerzos de muestreo en la probabilidad de detección de mapaches (Procyon lotor) y tlacuaches (Didelphis virginiana). Los tlacuaches tuvieron una probabilidad de detección mayor que los mapaches. El tamaño medio de parches de bosque tuvo un efecto negativo en la probabilidad de detección, sugiriendo que la hipótesis de que la abundancia de los depredadores medianos suba en parches pequeños del bosque es artefacto de muestreo. Sugerimos que es importante que los investigadores incluyan la probabilidad de detección cuando analicen datos de muestreos de depredadores medianos.
