Importance of Accounting for Detection Heterogeneity When Estimating Abundance: the Case of French Wolves
International audience Assessing conservation strategies requires reliable estimates of abundance. Because detecting all individuals is most often impossible in free-ranging populations, estimation procedures have to account for a <1 detection probability. Capture-recapture methods allow biologis...
