Fig. 3From: Estimation of pack density in grey wolf (Canis lupus) by applying spatially explicit capture-recapture models to camera trap data supported by genetic monitoringEffect of session length on wolf pack density estimates (grey line) and capture success (i.e., number of recaptures of focal animals, black line) in the study area (Arezzo province, Italy). Bars represent standard deviation and numbers near density estimates are the number of different packs detectedBack to article page
