稻田作为各种依赖湿地的物种的替代生境发挥着重要作用。然而，稻田的农业集约化对这些物种构成严重威胁。在这里，我们研究了环境因素，包括那些与现代农业实践，影响分布的佐渡皱蛙（Glandirana susurra）在稻田佐渡岛，日本。我们在2014年6月上旬和下旬在42个地点记录了大量的青蛙，并调查了该物种对几个当地和生态尺度变量的反应。我们发现，六月中旬稻田排水后，青蛙的丰度急剧下降，并且与稻田周围的深混凝土灌溉沟呈负相关。然而，在稻田中修建保护沟可以减轻排水的影响。我们的研究结果表明，保护沟作为避难所forG。susurra。我们建议，减少灌溉沟渠的深度或提供结构的青蛙使用和穿越沟渠可能是有用的方法，帮助conserveG。susurra。我们还建议增加保护沟渠的使用和在周围景观中实施水生群落生境可能有助于该物种的长期保护。
Paddy fields play an important role as alternative habitats for various wetland-dependent species. Agricultural intensification in paddy fields, however, presents serious threats to these species. Here, we examined the environmental factors, including those related to modern farming practices, affecting the distribution of the Sado wrinkled frog (Glandirana susurra) in paddy fields on Sado Island, Japan. We recorded the abundance of frogs at 42 sites in early and late June 2014 and investigated the species’ responses to several local and landscape-scale variables. We found that frog abundances decreased sharply following the drainage of paddy fields in mid-June and were negatively associated with deep concrete irrigation ditches that surrounded the paddies. The addition of conservation ditches built into rice paddy fields, however, was shown to mitigate against the effects of the drainage. Our results suggest that conservation ditches serve as refuges forG. susurra. We propose that decreasing the depth of irrigation ditches or providing structures for frogs to use and traverse the ditches could be useful approaches that help conserveG. susurra. We also suggest the increased use of conservation ditches and implementation of aquatic biotopes in the surrounding landscape might serve to aid this species’ long-term conservation.
