摘要

道路和高速公路是影响野生动物迁徙的最重要障碍之一,因为它们破坏了栖息地,改变了野生动物的迁徙和栖息地的使用,同时也因野生动物与车辆的相互作用而对野生动物和人类构成危险。为了降低公路路段的野生动物死亡率,并最大限度地减少对驾车者的伤亡,道路生态学家提出了适合野生动物安全通过道路的结构。在这项研究中,使用踪迹相机进行了摄影采样,以量化野生动物活动以及墨西哥联邦2号公路2个单独路段内现有涵洞、桥梁和排水沟的使用情况,之前的实地评估发现这些路段的活动水平很高。这些区域是保护野生动物的重要区域,众所周知,它们是美洲豹、黑熊和豹子等稀有物种的生物走廊。跟踪摄像机运行了1 记录该地区野生动物迁徙的年度周期。根据获得的照片,创建了一个数据库,其中包含每个野生动物涵洞互动的信息。在取样之前,对现有涵洞进行了清查,测量了高度、宽度、体积和周围栖息地,以确定假设的使用质量指数。在测试了涵洞之间使用指数的显著差异后,我们认识到所有涵洞对野生动物的迁移都同样重要,并且根据质量指数,涵洞的使用没有显著差异。

Wildlife Use of Drainage Structures Under 2 Sections of Federal Highway 2 in the Sky Island Region of Northeastern Sonora, Mexico
Roads and highways are 1 of the most significant obstacles affecting wildlife movement by fragmenting habitat, altering wildlife migration and use of habitat, while also being a danger to wildlife and humans caused by wildlife-vehicle interactions. To mitigate wildlife mortality on highway sections and to minimize death and injury to motorists as well, road ecologists have proposed structures adapted for the safe passage of wildlife across roads. In this study, photographic sampling was conducted using trail cameras to quantify wildlife activity and use of existing culverts, bridges, and drainages within 2 separate sections of Mexico Federal Highway 2 where previous field assessment had observed high levels of activity. These sections are important areas for the conservation of wildlife, and they are known to be biological corridors for rare species of concern such as jaguar, black bear, and ocelot. The trail cameras were operated for 1 year to document the annual cycle of wildlife movement through the area. With the photographs obtained, a database was created containing the information from each wildlife-culvert interaction. Prior to sampling, an inventory of existing culverts was conducted that measured height, width, volume, and surrounding habitat to assign a hypothesized use quality index. After testing for significant differences in use index among culverts, we recognized that all culverts were equally important for moving wildlife, and that there were no significant differences in the use of culverts by the quality index.

期刊介绍: Air, Soil & Water Research is an open access, peer reviewed international journal covering all areas of research into soil, air and water. The journal looks at each aspect individually, as well as how they interact, with each other and different components of the environment. This includes properties (including physical, chemical, biochemical and biological), analysis, microbiology, chemicals and pollution, consequences for plants and crops, soil hydrology, changes and consequences of change, social issues, and more. The journal welcomes readerships from all fields, but hopes to be particularly profitable to analytical and water chemists and geologists as well as chemical, environmental, petrochemical, water treatment, geophysics and geological engineers. The journal has a multi-disciplinary approach and includes research, results, theory, models, analysis, applications and reviews. Work in lab or field is applicable. Of particular interest are manuscripts relating to environmental concerns. Other possible topics include, but are not limited to: Properties and analysis covering all areas of research into soil, air and water individually as well as how they interact with each other and different components of the environment Soil hydrology and microbiology Changes and consequences of environmental change, chemicals and pollution.
