摘要: Effects of sampling/observation area size on correlations between hunter moose Alces alces observation rates and density estimates have been evaluated. Each correlation was examined to discover extreme values strongly influencing due small sample sizes. The results my study suggested that were affected by sampling size. Correlations densities indicate there is a positive asymptotic relationship rate accuracy area, i.e. as the increases, so does rate. It concluded could be improved using obtained in areas larger than 500 km2. concordance counts at this intermediate (rs = 0.5–0.7). smaller management un...
