Multi-state diel occupancy model

Current methods to model species habitat use through space and diel time are limited. Development of such models is critical when considering rapidly changing habitats where species are forced to adapt to anthropogenic change, often by shifting their diel activity across space. We use an occupancy modeling framework to specify the multi-state diel occupancy model (MSDOM), which can evaluate species diel activity against continuous response variables which may impact diel activity within and across seasons or years. We used two case studies, fosa in Madagascar and coyote in Chicago, USA, to conceptualize the application of this model and to quantify the impacts of human activity on species spatial use in diel time. We found support that both species varied their habitat use by diel states—in and across years, and by human disturbance. Our results exemplify the importance of understanding animal diel activity patterns and how human disturbance can lead to temporal habitat loss. The MSDOM ...

当前用于模拟物种在空间与昼夜时段内栖息地利用模式的方法仍存在局限。在栖息地快速变化、物种往往需通过调整空间分布的昼夜活动以适应人为干扰的背景下，此类模型的开发至关重要。我们采用占用模型（occupancy modeling）框架构建了多状态昼夜占用模型（multi-state diel occupancy model, MSDOM），该模型可针对可能影响季内、季间或年内昼夜活动的连续响应变量，评估物种的昼夜活动模式。我们以马达加斯加的马岛獴（fosa）与美国芝加哥的郊狼（coyote）为双案例研究，阐释该模型的应用路径，并量化人类活动对物种在昼夜时段内空间利用模式的影响。研究结果证实，两种物种均会依据昼夜时段（涵盖年内及年际变化）与人类干扰程度调整其栖息地利用策略。本研究结果凸显了明晰动物昼夜活动模式，以及人类干扰如何引发暂时性栖息地丧失的重要意义。The MSDOM ...
