池塘面积和可用性保护了伊比利亚最大的受保护湿地中两栖动物的遗传多样性

全世界的湿地生态系统都受到栖息地改变、气候变化和入侵物种引入的威胁，即使在保护区内也是如此。因此，了解敏感的湿地栖息物种（如两栖动物）对栖息地特征的依赖对确定保护目标至关重要。在这里，我们评估了两种强水生两栖动物（Pelophylax perezi 和 Pleurodeles waltl）的遗传多样性分布情况，以及伊比利亚半岛最广阔的受保护湿地的栖息地特征：多纳纳国家公园。尽管 P. perezi 和 P. waltl 栖息在没有人为障碍的保护区内，但它们的遗传多样性并没有均匀地分布在整个湿地，而是集中在核心区域，主要是北部地区。遗传多样性和连通性（相对于遗传分化）都与繁殖地的面积和繁殖地周围的洪泛区在物种扩散潜力（即附近池塘的可用性）范围内呈显著的正相关。与丰富的临时池塘相连的大型水体是维持两栖动物遗传多样性的关键。然而，我们的目标物种具有明显的水生习性，其核心种群却集中在被入侵物种侵占的地区，这可能会影响其长期生存能力。我们的研究结果突出表明，保持不同水文周期的池塘阵列广泛相连，包括没有入侵捕食者和竞争者的大型繁殖地，对于保护地中海湿地的两栖动物至关重要。

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.
