摘要翻译:
从标准标记-再捕获技术中,通过捕获、标记和再捕获来收集数据,为估计动物的家域提供了理论依据。所用的理论工具是福克-普朗克方程,其特征量是描述动物运动的扩散常数,以及说明它们在洞穴附近生活的趋势的吸引势。结果表明,该测量技术对应于在对应于捕获区域的空间中,与特定探测窗口相关的动物的某种均方位移的计算。该理论的输出是可观测均方位移随归属范围与俘获区距离之比的变化曲线,并给出了从观测值中提取归属范围的显式公式。指出了该理论在巴拿马和新墨西哥州啮齿动物运动中的应用。通过各种有代表性的例子,分析了我们的理论对限制势选择的敏感性。比较了从我们的方法和从文献中使用的其他程序中推断的家庭范围大小。本文还讨论了家庭范围重叠的后果。

英文摘要:
A theory is provided for the estimation of home ranges of animals from the standard mark-recapture technique in which data are collected by capturing, tagging and recapturing the animals. The theoretical tool used is the Fokker-Planck equation, its characteristic quantities being the diffusion constant which describes the motion of the animals, and the attractive potential which addresses their tendency to live near their burrows. The measurement technique is shown to correspond to the calculation of a certain kind of mean square displacement of the animals relevant to the specific probing window in space corresponding to the trapping region. The output of the theory is a sigmoid curve of the observable mean square displacement as a function of the ratio of distances characteristic of the home range and the trapping region, along with an explicit prescription to extract the home range form observations. Applications of the theory to rodent movement in Panama and New Mexico are pointed out. An analysis is given of the sensitivity of our theory to the choice of the confining potential via the use of various representative cases. A comparison is provided between home range size inferred from our method and from other procedures employed in the literature. Consequences of home range overlap are also discussed.
