Evaluation of random sampling for estimating density of winter ticks (Dermacentor albipictus) on moose (Alces alces)

Abstract:
Densities of winter ticks (Dermacentor albipictus) were determined on each of 20 moose (Alces alces) half-hides by dissolving 100 cm2 quadrats in potassium hydroxide solution. Data were then used to determine the optimum sampling fraction for estimating tick densities. Random sampling was applied to 20 additional half-hides of known tick density to assess the accuracy of the estimates. We conclude that random sampling of 15% of the quadrats produces a good estimate of tick density. Total numbers of ticks were highly correlated with tick density.
