摘要

喀拉拉邦西部高止山脉(生物多样性热点)蓝藻物种多样性丰富。蓝藻属Nostoc栖息在天然岩石表面，通过在新的和未确定的生态位中定殖，在陆地生态系统中发挥重要作用。温度、pH、湿度、微观和宏观营养物质等非生物因素对Nostoc在岩石表面的丰度有重要影响。Nostoc是生态友好和可持续农业的潜在候选者。尽管如此，它们对环境的重要意义，大多数Nostoc物种尚未被探索，特别是在喀拉拉邦的西高止山脉地区。因此，本研究调查了喀拉拉邦西部高止山区的石柱类念珠菌的多样性。本研究共鉴定出25种附石念珠菌属。25种中，Nostoc tibetum和N. indeindem为印度新记录种。

Diversity of Epilithic Nostoc spp. from Western Ghats Regions of Kerala, India

Western ghats (Biodiversity hotspot) of Kerala is abundant in cyanobacterial species diversity. The cyanobacterial genus Nostoc inhabits on natural rock surfaces, thus play an important role in terrestrial ecosystems by colonizing in new and unsettled ecological niches. The abiotic factors like temperature, pH, humidity, micro and macro nutrients contribute to the abundance of Nostoc spp. on the rock surface. Nostoc spp. act as a potential candidates for eco-friendly and sustainable agriculture. Even though, their substantial importance to the environment most of the Nostoc spp. are unexplored, especially from Western ghats region of Kerala. Hence, the present study investigated the diversity of epilithic Nostoc spp. from Western ghats regions of Kerala. A total of 25 epilithic Nostoc spp. were identified in this study. Among the 25 species, Nostoc tibeticum and N. indistinguindem are new records from India.

期刊介绍： The algae are heterogeneous assemblage of phytosynthetic organisms, one of the most vast and diverse groups of ancient photoautotrophic pro- and eukaryotic organisms (about 30 000 known species). They are micro- and macroscopic, unicellular, colonial, or multicellular, mobile and immobile, attached and free-living. Algae are widespread in water and soil habitats, at different geographic latitudes, and on all continents. They occur in waters with different degrees of salinity, trophicity, organic matter, and hydrogen ions, and at various temperatures. They include planktonic, periphytonic and benthic organisms. Algae are unique model organisms in evolutionary biology and also are used in various genetic, physiological, biochemical, cytological, and other investigations.
