我们描述了一类灵活的动物运动的连续时间模型，允许运动行为取决于一组离散区域的位置，也取决于潜在的行为状态。我们证明了这些模型能够表示复杂的行为和空间异质性，就像在真实的运动研究中发现的那样，同时保持了可操纵性和连续时间公式的概念优势。我们讨论了这里定义的模型与一系列重要应用之间的关系，当运动行为是主要焦点时，以及当它本质上是一个滋扰过程时，例如在空间显式捕获-重新捕获中。(C)2013爱思唯尔B.V.保留所有权利。
We describe a flexible class of continuous-time models for animal movement, allowing movement behaviour to depend on location in terms of a discrete set of regions and also on an underlying behavioural state. We demonstrate the ability of these models to represent complex behaviour and spatial heterogeneity, as found in real movement studies, while retaining tractability and the conceptual advantages of a continuous-time formulation. We discuss the relationship between the models defined here and a range of important applications, both when movement behaviour is the main focus and when it is essentially a nuisance process, for example in spatially explicit capture-recapture.
