Aerial distance sampling of bears to estimate population size has been used throughout many parts of Alaska. The distance sampling models are complex since they need to account for undetected bears and differences in detection probabilities. This will require covariates and mark-recapture data. The models proposed by Schmidt et al. do not use covariates or mark-recapture data and are inappropriate for these surveys.
在阿拉斯加的许多地区,都采用了对熊进行空中距离抽样的方法来估计种群数量。距离抽样模型很复杂,因为它们需要考虑未被发现的熊以及检测概率的差异。这将需要协变量和标记重捕数据。施密特等人提出的模型没有使用协变量或标记重捕数据,不适用于这些调查。
