The species diversity in various salinity zones was in the order: saline zone- 80 species > estuarine zone- 28 species > freshwater zone- 14 species. The report includes three species new to the west coast of India: <i>Assiminea woodmasoniana</i> G. Nevill, 1880, <i>Rugalucina vietnamica</i> (Zorina, 1978) and <i>Platevindex martensi</i> (Plate, 1893). Species: such as <i>Chiton granoradiatus</i> Leloup, 1937; <i>Clithon sowerbianum</i> (Recluz, 1843); <i>Littoraria pallescens</i> (Philippi, 1846); <i>Acteocina decorate</i> (Pilsbry, 1904); <i>Alaona ala</i> (Hanley, 1845) and <i>Serratina siamensis</i> (E. von Martens, 1860) are new to Kerala. The paper analyses the alpha and beta diversity of molluscs in the Ashtamudi Lake, Kerala.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Diversity and spatial distribution of molluscs along the salinity gradient in Ashtamudi Lake Ramsar site, Kerala, India","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:32:11.255695","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Ashtamudi, Salinity, Estuary, Gastropods, Bivalves, Diversity index","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-09-18","DateCreate":"2023-09-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.26515/rzsi/v123/i1S/2023/172458"},"refs":null,"anarec":{"AnaID":366800,"PubliDate":2023,"Pagination":"359-371","XtraPublOfAnaID":null,"ISBN":null,"Volume":"123","Issue":"iS2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":224295,"SerRR":"Records of the Zoological Survey of India.
