Sex ratio of leopards taken in trophy hunting: genetic data from Tanzania


The sex ratio of leopards, Panthera pardus, taken by trophyhunters in Tanzania is examined. We used sex specific molecularmarkers to analyze 77 samples collected from animals shot betweenthe years 1995–1998 and found that 28.6% were females, despitethe fact that only males are allowed on licenses and all skinswere tagged as males. The model used for quota setting assumesthat only males are shot, but the effect of this violation ofquotas is unknown. Off-take in Tanzania does not currently fillquotas, but when off-take approach maximum levels, compliancewith set quotas and regulations will be critical for sustainableharvest.
