The first data on the Lemanea genus in Serbia come from the late 20th century. Only one species, L. fluviatilis , was reported from 10 localities in Serbian riverine ecosystems between 1991 and 2017. Extensive research on this genus was performed in April–November 2017–2019, surveying 150 localities in 97 upland and mountain rivers. During this study period, the Lemanea genus was recorded at 14 localities in 12 rivers, while it disappeared from five previously reported localities. A total of four taxa were identified: Lemanea fucina , L. rigida , Lemanea sp. and L. fluviatilis. Lemanea fucina and L. rigida were recorded in Serbia for the first time. L. fluviatilis was the most common taxon. Our research confirmed that Lemanea species prefer similar specific environmental conditions. These species were found in temperate, soft or moderately hard, well-oxygenated and weakly alkaline waters, with low, moderate or high conductivity, and in waters with low content of inorganic nutrients. Due to their sensitivity to changes in environmental conditions, Lemanea species are exposed to negative anthropogenic impact leading to the degradation of their habitats. Intensive construction of small hydropower plants has threatened most habitats of the Rhodophyta species in the last few years.

塞尔维亚Lemanea属的研究综述

塞尔维亚Lemanea属的第一个数据来自20世纪后期。1991年至2017年间,塞尔维亚河流生态系统的10个地区仅报告了一种L.fluviatilis。2017年4月至11月至2019年11月,对该属进行了广泛的研究,调查了97条山地和山区河流中的150个地区。在本研究期间,Lemanea属被记录在12条河流的14个地方,而先前报告的5个地方则消失了。总共鉴定出四个分类单位:Lemanea fucina,L.僵硬,Lemanea sp。和L. fluviatilis。Lemanea fucina和L.僵硬菌是在塞尔维亚首次记录的。fluviatilis是最常见的分类单位。我们的研究证实,Lemanea物种更喜欢类似的特定环境条件。这些物种存在于温带,软或中硬的地方,氧含量高,电导率低,中等或高的弱碱性水,以及无机养分含量低的水。由于其对环境条件变化的敏感性,Lemanea物种受到人类活动的负面影响,导致其栖息地退化。在过去的几年中,小型水力发电厂的集约化威胁了红藻种类的大多数栖息地。
