Home range behaviour is a common pattern of space use, having fundamental consequences for ecological processes. However, a general mechanistic explanation is still lacking. Research is split into three separate areas of inquiry - movement models based on random walks, individual-based models based on optimal foraging theory, and a statistical modelling approach - which have developed without much productive contact. Here we review recent advances in modelling home range behaviour, focusing particularly on the problem of identifying mechanisms that lead to the emergence of stable home ranges from unbounded movement paths. We discuss the issue of spatiotemporal scale, which is rarely considered in modelling studies, as well as highlighting the need to consider more closely the dynamical nature of home ranges. Recent methodological and theoretical advances may soon lead to a unified approach, however, conceptually unifying our understanding of linkages among home range behaviour and ecological or evolutionary processes.
家域行为是一种常见的空间利用模式，对生态过程有着根本性的影响。然而，目前仍缺乏一个通用的机制性解释。相关研究分为三个独立的探究领域——基于随机游走的运动模型、基于最优觅食理论的个体模型以及统计建模方法——这些领域在发展过程中缺乏有效的相互交流。在此，我们回顾了家域行为建模的最新进展，特别关注从无界运动路径中识别导致稳定家域出现的机制这一问题。我们讨论了时空尺度问题，这在建模研究中很少被考虑，同时强调需要更密切地考虑家域的动态本质。近期的方法和理论进展可能很快会带来一种统一的方法，然而，在概念上统一我们对家域行为与生态或进化过程之间联系的理解。
