Abstract

In the present study, we identified nine red algal species from the intertidal rocky shore of the Visakhapatnam coast, Bay of Bengal, India, using an integrated taxonomic approach, including morphological, anatomical, and multigene phylogenetic analyses based on SSU rDNA, rbcL, and COI gene markers. Seven of them were the new records to the study area, including Centroceras gasparrinii, Gelidium nayaritense, Pterocladiella bartlettii, Hypnea charoides, Hypnea cf. edeniana, Gracilaria multifurcata, and Gracilaria rangiferina. Of these seven species, P. bartlettii, G. multifurcata, and G. rangiferina were new records to the Bay of Bengal coast, whereas H. cf. edeniana and G. nayaritense were new records to the Indian Ocean. Our result suggested that red algal species cataloging is still under-representation in the study area. In the future, systematic sampling strategies from different tidal zones across different times of the year may report more new records and new species of red algae from this coastline.

印度孟加拉湾维萨卡帕特南海岸潮间带岩岸红藻的新记录

本研究以印度孟加拉湾维萨卡帕特南海岸潮间带岩岸的9种红藻为研究对象，采用基于SSU rDNA、rbcL和COI基因标记的形态学、解剖学和多基因系统发育分析等综合分类学方法对其进行了鉴定。其中7种为研究区新记录，分别为：石竹（centrroceras gasparrinii）、石竹（Gelidium nayaritense）、石竹（Pterocladiella bartlettii）、石竹（Hypnea choides）、石竹（Hypnea cfe.edeniana）、木竹（Gracilaria multifurata）和龙竹（Gracilaria rangiferina）。其中，P. bartlettii、G. multifurata和G. rangiferina是孟加拉湾沿岸的新记录，H. cfedeniana和G. nayaritense是印度洋沿岸的新记录。研究结果表明，研究区红藻物种编目工作仍然不足。在未来，系统的采样策略在不同的潮汐带在一年的不同时间可能会报告更多的新记录和新物种的红藻从这条海岸线。

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
