摘要

保护野生动物的活动走廊对物种保护至关重要。城市规划通常旨在通过保护措施为动物创造活动走廊。然而,有关城市野生动物连通性的研究十分有限。在这里,我们利用加拿大多伦多市 27 只全球定位系统(GPS)领标郊狼的栖息地选择参数,跨时间尺度和人口特征动态评估了郊狼(Canis latrans)的连通性。栖息地选择模型考虑了人口密度、不透水面积、植被密度以及与不同线性特征的距离。结果表明:(1) 植被密集区是城市地区连通性的关键;(2) 河岸、铁路和电线下方区域被预测为移动走廊;(3) 商业和工业集群严重破坏了连通性。连通性的时空差异与一天中的时间和郊狼的社会地位有关,但与气候、生物季节性或郊狼的年龄和性别无关。居住区道路在连通性的时间动态变化中起着关键作用。在管理城市中的连通性走廊时,应考虑维护和提高主要基础设施(如公路、水道和停车场)沿线植物结构的复杂性。

Dynamic connectivity assessment for a terrestrial predator in a metropolitan region
Protecting wildlife movement corridors is critical for species conservation. Urban planning often aims to create corridors for animal movement through conservation initiatives. However, research on connectivity for urban wildlife is limited. Here, we assessed connectivity for coyotes (Canis latrans) dynamically across temporal scales and demographic traits, parametrized using the habitat selection of 27 global positioning system (GPS)‐collared coyotes in the city of Toronto, Canada. The habitat selection models accounted for human population density, impervious area, vegetation density, and distance to different linear features. Results indicated that (1) vegetation‐dense areas were key for connectivity in urban areas; (2) riverbanks, railways, and areas below power lines were predicted as movement corridors; and (3) commercial and industrial clusters strongly disrupted connectivity. Spatiotemporal differences in connectivity were associated with time of day and coyote social status but not with climate and biological seasonality or coyote age and sex. Residential roads were pivotal in the temporal dynamism of connectivity. The maintenance and enhancement of plant structural complexity along key infrastructure (for example, highways, waterways, and parking lots) should be considered when managing connectivity corridors in cities.

期刊介绍: Frontiers in Ecology and the Environment is a publication by the Ecological Society of America that focuses on the significance of ecology and environmental science in various aspects of research and problem-solving. The journal covers topics such as biodiversity conservation, ecosystem preservation, natural resource management, public policy, and other related areas. The publication features a range of content, including peer-reviewed articles, editorials, commentaries, letters, and occasional special issues and topical series. It releases ten issues per year, excluding January and July. ESA members receive both print and electronic copies of the journal, while institutional subscriptions are also available. Frontiers in Ecology and the Environment is highly regarded in the field, as indicated by its ranking in the 2021 Journal Citation Reports by Clarivate Analytics. The journal is ranked 4th out of 174 in ecology journals and 11th out of 279 in environmental sciences journals. Its impact factor for 2021 is reported as 13.789, which further demonstrates its influence and importance in the scientific community.
