功能特征驱动蝌蚪对沿海地区土地利用的反应

土地使用的变化被认为是全球两栖动物减少的一个重要原因。然而，人们对哪些土地利用具有更普遍的影响以及哪些土地利用有助于补充保护区所保护的生物多样性知之甚少。此外，两栖动物物种会对一系列广泛的地理限制做出反应，这可能会模糊物种对干扰的反应，这取决于物种的自然历史。在此，我们探讨了两栖动物群落的功能多样性模式是否与人类土地利用有关，同时考虑了物种间的空间自相关性和系统发育相关性。我们在巴西南部沿海湿地的 500 公里沿线对蝌蚪进行了调查，并量化了与蝌蚪栖息地利用和避开捕食者有关的四个特征。与土地利用相比，空间成分对功能丰富度的影响更大。池塘周围外来植树造林较多的地方，功能均匀度较高，而作物面积的影响较小。功能差异也与植树造林区域有关。我们的研究结果表明，某些土地利用（外来物种造林和临时作物）对蝌蚪群落的影响更为普遍。即使景观变化程度较低，两栖动物群落也会发生这种变化。我们的研究结果突出表明，人类土地用途的转换需要互补的方法（即蝌蚪和成体的反应）来提供生境改变影响的早期预警信号。

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.
