摘要

在美国西部干旱地区，河岸生态系统只占不到 2% 的面积，但却为一半以上的干旱地区野生动物提供了栖息地和资源，其中包括种类繁多的无尾类动物（青蛙和蟾蜍）。尽管如此，描述西南部河岸底栖动物群落的研究相对较少，偏远荒野地区的调查尤其不足。我们采用了被动声学监测技术来捕捉美国亚利桑那州佛得河荒野地区支流中的无尾类广告叫声。在 2021 年和 2022 年的春季和夏季，我们沿常年、间歇和短暂的支流河段部署了 13-29 个自主记录单元（ARUs）。我们根据每个自动记录单元 100 米范围内的水池、涟漪、流水和边沟栖息地的百分比来确定地点的特征，并对基质、湿润河道宽度和树冠覆盖率进行量化。为了将无尾类动物的栖息地与环境和水文变量联系起来，我们使用单物种、单季节栖息地模型对声学探测数据进行了评估。本研究检测到了四种物种：峡谷树蛙（Hyla arenicolor）、红点蟾蜍（Anaxyrus punctatus）、伍德豪斯蟾蜍（Anaxyrus woodhousii）和非本地美洲牛蛙（Lithobates catesbeianus），其中峡谷树蛙是观察到的最普遍的物种。峡谷树蛙在多年生和间歇性水域的发声活动比在短暂水域的发声活动要高，水池的存在与峡谷树蛙的栖息地关系最为密切。持续、缓慢流动的水最能预示峡谷树蛙繁殖的存在。值得注意的是，本研究未在佛得河中游流域发现几个有历史记录的物种，包括亚利桑那蟾蜍（Anaxyrus microscaphus）和北方豹蛙（Lithobates pipiens）。鉴于气候变化导致的流量减少以及全球干旱地区对水的需求不断增加，保持溪流流量，为无尾类动物的繁殖和幼体发育提供稳定、适宜的水文条件变得越来越重要。确定支持无尾类种群所需的栖息地使用情况和水流机制有助于确定与水管理相关的保护行动的优先次序，并预测水供应的变化可能会如何影响溪流繁殖的无尾类。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
