摘要

《北美水禽管理计划》强调了提高水禽栖息地的生产力和适应力的重要性。在湿地进行多种形式的土地管理,以支持水禽和其他物种的多样化群落。原生穴居小龙虾在这些环境中也很丰富和重要,但很少有研究评估水禽土地管理对原生穴居小龙虾的影响。在密苏里州东南部的水禽保护区,我们研究了挖掘小龙虾(Creaserinus fodiens)对割草和圆盘等常见植被管理措施的反应。结果表明,在小尺度上,小龙虾密度仅受林冠覆盖度的影响。我们还强调了景观水平环境变量的分布效应,并认为生境通用性对植被管理的容忍度更高,对植被组成和更广泛的景观效应有更大的响应。我们讨论了湿地的保护措施,并建议将穴居小龙虾的管理与现有的水禽管理策略相结合。

Integrating burrowing crayfish and waterfowl conservation management on moist-soil wetlands
Summary The North American Waterfowl Management Plan highlights the importance of enhancing waterfowl habitat for productivity and resilience. Many forms of land management are conducted in wetlands to support the diverse communities of waterfowl and other species. Primary burrowing crayfish are also abundant and important in these environments, but little research is available assessing the effects of waterfowl land management on primary burrowers. We examined the response of the digger crayfish, Creaserinus fodiens, to the common vegetation management practices of mowing and disking at waterfowl conservation areas in south-eastern Missouri. Our results demonstrated that at a fine scale, crayfish density was affected by only canopy cover. We also highlighted distributional effects of landscape-level environmental variables and suggested that habitat generalists were tolerant of vegetation management, responding more to vegetation composition and broader landscape effects. We discuss wetlands conservation practices and suggest that burrowing crayfish management would integrate well with some current management strategies for waterfowl.

期刊介绍: Environmental Conservation is one of the longest-standing, most highly-cited of the interdisciplinary environmental science journals. It includes research papers, reports, comments, subject reviews, and book reviews addressing environmental policy, practice, and natural and social science of environmental concern at the global level, informed by rigorous local level case studies. The journal"s scope is very broad, including issues in human institutions, ecosystem change, resource utilisation, terrestrial biomes, aquatic systems, and coastal and land use management. Environmental Conservation is essential reading for all environmentalists, managers, consultants, agency workers and scientists wishing to keep abreast of current developments in environmental science.
