Mediterranean wetlands are severely affected by habitat degradation and related loss of biodiversity. In this scenario, the wide number of artificial farm ponds can play a significant role in the biodiversity conservation of aquatic flora. In the present contribution we show the preliminary results of a study on Mediterranean farm ponds of north-western Sicily (Italy), aimed to investigating the environmental factors linked to the occurrence of submerged macrophytes (vascular plants and charophytes). We studied the aquatic flora of 30 ponds and determined the chemical and isotopic composition of their water bodies on a subset of the most representative 10 sites. Results show that (1) farm ponds host few but interesting species, such as considered threatened at regional level; (2) and behave as disturbance-tolerant species, occurring both in nitrates-poor and nitrates-rich waters, whereas and occur only in nitrates-poor waters. Although farm ponds are artificial and relatively poor habitats, these environments seem to be important for the aquatic flora and for the conservation of the local biodiversity, and can give useful information for the use of macrophytes as bioindicators in the Mediterranean area.
地中海湿地受到栖息地退化及相关生物多样性丧失的严重影响。在这种情况下，大量的人工养殖池塘可在水生植物生物多样性保护中发挥重要作用。在本论文中，我们展示了一项针对意大利西西里岛西北部地中海养殖池塘的研究初步结果，旨在调查与沉水植物（维管植物和轮藻）出现相关的环境因素。我们研究了30个池塘的水生植物，并在最具代表性的10个地点的子集中测定了其水体的化学和同位素组成。结果表明：（1）养殖池塘中物种数量不多但很有趣，例如 被认为在区域层面受到威胁；（2） 和 表现为耐干扰物种，在硝酸盐含量低和高的水域均有出现，而 和 仅出现在硝酸盐含量低的水域。尽管养殖池塘是人工的且相对贫瘠的栖息地，但这些环境似乎对水生植物和当地生物多样性保护很重要，并且可为在地中海地区将大型植物用作生物指示物提供有用信息。
