This dataset records the occurrence and inventory of molluscan fauna on Gueishan Island, the only active volcanic island in Taiwan, based on the literature survey and field investigation conducted between 2011 and 2012. The literature review involved seven studies published from 1934 to 2003, which collectively reported 112 species from 61 genera and 37 families of Mollusca on Gueishan Island. ...
هدف از تحقیق حاضر، تشخیص تفاوت بین گونه ای سوهانک در سه گونه از شکم پایان خانواده Neritidae در مناطق بین کشندی جزیره خارگ توسط مطالعه سوهانک توسط میکروسکوپ نوری و الکترونی نگاره بود. نمونه برداری شکم پایان در زمستان 1394 و بهار 1395 (هر فصل یک بار) و از 5 ایستگاه در مناطق بین کشندی جزیره خارگ و عمق کم تر از یک متر انجام شد. نمونه ها بلافاصله فریز ...
Three malacological surveys were conducted in the Takua Pa District of Phang-Nga Province, southern Thailand, before and after the Indian Ocean Tsunami disaster. Twenty-nine species of fresh- and brackish-water snails were found, in which 10 species of freshwater snails were present, including live Pila polita; 8 species were of medical importance. Two brackish-water snails, Nerita articulata a...
The Southwest Indian Ocean (SWIO) is a striking marine biodiversity hotspot. Coral reefs in this region host a high proportion of endemics compared to total species richness and they are particularly threatened by human activities. The island archipelagos with their diverse marine habitats constitute a natural laboratory for studying diversification processes. Rocky shores in the SWIO region ha...
The aim of this research was to identify and isolate the fatty acids composition of Nerita textiles in intertidal area of Chabahar Bay, and also to explore the seasonal changes of fatty acid content in Nerita textiles. GC/MS resulted thirteen fatty acids, that saturated fatty acids (SFA) of palmitic acid (16:0) was the most abundant category of fatty acid obtained in total lipids. There were no...

Comparative study has been done to examine the biodiversity and ecological status of the intertidal region of Tata Institute of Fundamental Research (TIFR), Bandstand and National Centre for Performing Arts (NCPA) rocky beaches in Mumbai, West coast of India. A total of 50 species of intertidal organisms were recorded from these shores. Shannon and Simpson's diversity index, Margalefs richness ...
در این پژوهش شناسایی مولکولی گونههای جنس Nerita، شامل N. lognii، N. albicilla و N. polita، در سواحل شمالی خلیجفارس به همراه بررسی مورفولوژیک آنها انجام شد. این جنس متعلق به خانواده Neritidae بوده و از گونههای غالب شکمپایان سواحل صخرهای میباشد. نمونهبرداری در سالهای 92 و 93 در سواحل صخرهای صورت گرفت. نمونهها مورد شناسایی مورفولوژیک قرار گرفتند و سپس مراحل استخراج DNA (با استفاده از پو...
The mitochondrial DNA (mtDNA) cytochrome oxidase I (COI) gene has been universally and successfully utilized as a barcoding gene, mainly because it can be amplified easily, applied across a wide range of taxa, and results can be obtained cheaply and quickly. However, in rare cases, the gene can fail to distinguish between species, particularly when exposed to highly sensitive methods of data an...
