摘要
摘要本研究于2018年至2019年在巴基斯坦白沙瓦山谷进行,首次研究了水质对轮藻空间分布的影响。在白沙瓦山谷的7条河流、16条溪流和两个湿地的41个地点共发现了6个轮藻类群:Chara braunii C.C.Gmelin、C.consulations Salzmann ex A.Braun、C.reversia A.Braun ex Kützing、C.globularis Thuiller、C.vulgaris Linnaeus和Nitellopsis obtusa(Desvaux)J.Groves。夏枯草(Chara vulgaris)是数量最多的物种,其次是球孢夏枯草(C.globularis)和反向夏枯草(C.reveria)。水的pH值、电导率(EC)、总溶解固体(TDS)、盐度和溶解氧(DO)均在巴基斯坦的允许范围内,而水温、氧化还原电位(ORP)和电阻率则出现偏差。典型对应分析(CCA)表明,DO影响夏枯草,pH和电阻率影响布氏锥虫、纵容锥虫和球孢锥虫,温度和ORP影响反向锥虫和钝锥虫。此外,CCA还表明,TDS、EC和盐度对中华绒螯蟹、C.vulgaris和Nitellopsis obtusa的空间分布没有影响。应根据VU(易危)状态(IUCN)及其栖息地进行保护。
Effect of water quality on the spatial distribution of charophytes in the Peshawar Valley, Khyber Pakhtunkhwa, Pakistan
Abstract The presented research was conducted in 2018–2019 in the Peshawar Valley, Pakistan, to study for the first time the effect of water quality on the spatial distribution of charophytes. A total of six taxa of charophytes were found at 41 sites in the Peshawar Valley along the banks of seven rivers, 16 streams and two wetlands: Chara braunii C.C.Gmelin, C. connivens Salzmann ex A. Braun, C. contraria A. Braun ex Kützing, C. globularis Thuiller, C. vulgaris Linnaeus, and Nitellopsis obtusa (Desvaux) J. Groves. Chara vulgaris was the most abundant species, followed by C. globularis, and C. contraria. Water pH, electrical conductivity (EC), total dissolved solids (TDS), salinity and dissolved oxygen (DO) were within the permissible limits for Pakistan, while water temperature, oxidation reduction potential (ORP) and resistivity showed deviations. Canonical Correspondence Analysis (CCA) revealed that DO affected Chara vulgaris, pH and resistivity affected C. braunii, C. connivens and C. globularis, temperature and ORP affected C. contraria and Nitellopsis obtusa. Furthermore, CCA showed that TDS, EC, and salinity had no effect on the spatial distribution of Chara contraria, C. vulgaris and Nitellopsis obtusa. Chara contraria and Nitellopsis obtusa should be protected under VU (Vulnerable) status (IUCN) along with their habitats.
