Abstract The paper presents the first record of a Chara connivens (Characeae) stand from Fuerteventura (Canary Islands, Spain). The species was previously recorded only on Tenerife and Lanzarote, mostly in marine and artificial habitats. Physicochemical parameters of water and morphological features of the thalli and plant community were analyzed. General habitat requirements of C. connivens populations located in Europe, North Africa, and South-West Asia were reviewed. The newly described stand was located in a natural rock crevice that was part of a riverbed in El Barranco de las Peñitas (Penitas Canyon). This habitat was unshaded and filled with brackish water. C. connivens co-occurred with Cladophora glomerata and Ruppia maritima. Our report on the presence of C. connivens in the Spanish territory of the Atlantic Ocean is the first in almost 40 years. The distribution of C. connivens and its plant associations on the Canary Archipelago are poorly explored, which is why this topic requires further research.

加那利群岛Chara connivens（Charophyta，Characeae）的生态和分布模式——富埃特文图拉岛的第一项记录

摘要 本文介绍了来自富埃特文图拉岛（西班牙加那利群岛）的 Chara connivens（Characeae）林分的第一个记录。该物种以前仅在特内里费岛和兰萨罗特岛被记录，主要在海洋和人工栖息地中。分析了水的理化参数和菌体和植物群落的形态特征。审查了位于欧洲、北非和西南亚的 C. connivens 种群的一般栖息地要求。新描述的展台位于天然岩石裂缝中，该裂缝是 El Barranco de las Peñitas（佩尼塔斯峡谷）河床的一部分。这个栖息地没有阴影，充满了咸水。C. connivens 与 Cladophora glomerata 和 Ruppia maritima 共同发生。我们关于 C 存在的报告。近 40 年来，在大西洋的西班牙领土上举行的会议是第一次。C. connivens 的分布及其在加那利群岛上的植物群落的研究很少，这就是为什么该主题需要进一步研究的原因。
