Abstract

Ruppia drepanensis Tineo ex Guss. is an important habitat-forming aquatic plant in saline and brackish Mediterranean wetlands. The species is declining in several parts of its range due to hydrological changes and habitat degradation. R. drepanensis was considered Critically Endangered, possibly Regionally Extinct in Portugal, due to not being observed since 1986 despite extensive surveys of suitable habitat. We report on a new population, the westernmost known record for the species in Europe, identified with morphological and molecular data. Despite being inside a protected area, this population occupies a single small pond adjacent to a road, making it vulnerable to habitat changes. Ex situ conservation is recommended, including seed banking and/or the establishment of new populations.

未区域性灭绝：在欧洲最西端边缘的葡萄牙重新发现Ruppia drepanensis

芦笋（Ruppia drepanensis）。是地中海咸水和半咸水湿地重要的成生境水生植物。由于水文变化和栖息地退化，该物种在其分布范围的几个部分正在减少。尽管对其适宜的栖息地进行了广泛的调查，但自1986年以来一直未被观察到，因此在葡萄牙，drepanensis被认为是极度濒危的，可能是区域性灭绝的。我们报告了一个新的种群，这是欧洲最西端已知的物种记录，通过形态学和分子数据进行了鉴定。尽管在一个保护区内，这个种群占据了一个毗邻道路的小池塘，这使得它很容易受到栖息地变化的影响。建议迁地保护，包括种子库和/或建立新的种群。

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
