摘要

运动模型经常被拟合到动物位置数据中,以了解个体如何响应当地环境特征并与之相互作用。目前有几种开源软件包可用于分析动物运动,并能促进参数估计,但可用来评估模型拟合优度的方法相对较少。我们介绍了如何使用一种简单的图形技术--阵容协议来评估综合阶跃选择分析和隐马尔可夫模型的拟合度,但这种方法的应用范围要广泛得多。我们利用拟合模型模拟数据的能力,并使用综合阶跃选择分析和隐马尔可夫模型对渔夫(Pekania pennanti)数据进行了演示。可以使用各种响应和运动指标来评估模型,还可以对排查方案进行定制,以重点关注特定的模型假设或主要关注的运动特征。虽然可以使用正式的假设检验来评估统计意义,但该方法也可以以更具探索性的方式使用(例如,在随机模拟中探索模型行为的变异性或确定模型可以改进的地方)。我们提供了编码示例和小故事来展示该方法的灵活性。我们鼓励运动生态学家在选择适当的图形响应以评估拟合度时,考虑如何应用他们的模型。

期刊介绍: A British Ecological Society journal, Methods in Ecology and Evolution (MEE) promotes the development of new methods in ecology and evolution, and facilitates their dissemination and uptake by the research community. MEE brings together papers from previously disparate sub-disciplines to provide a single forum for tracking methodological developments in all areas. MEE publishes methodological papers in any area of ecology and evolution, including: -Phylogenetic analysis -Statistical methods -Conservation & management -Theoretical methods -Practical methods, including lab and field -This list is not exhaustive, and we welcome enquiries about possible submissions. Methods are defined in the widest terms and may be analytical, practical or conceptual. A primary aim of the journal is to maximise the uptake of techniques by the community. We recognise that a major stumbling block in the uptake and application of new methods is the accessibility of methods. For example, users may need computer code, example applications or demonstrations of methods.
