Book excerpt: "Abstract: The descriptive taxonomic records of a total of 226 gorgonian species (Octocorallia: Alcyonacea) from Indian seas and neighbouring areas were surveyed and critically reviewed with the main aim of providing a more reliable checklist. The published accounts comprise: species originally described from within the region: subsequent descriptive records of the taxa originally described from within the region; and subsequent descriptive records of species originally described from outside of the region. The reviews include an attempt to assess the validity of all subsequent descriptive records, although in numerous cases the species have been assessed as unrecognisable from their type descriptions. Numerous new binomial combinations, some tentative, have been proposed. The assessment of the validity of a species record is expressed as an "Opinion" with supporting justification. Of the 226 species, there are 111 that were originally described from locations outside of Indian waters and have subsequently been described and recorded as occurring in the region. Of these, there are 9 species where we were unable to decide if the records are valid or not, 94 were assessed as invalid, 5 as possibly valid and 3 were considered valid. The survey highlights four major problems regarding the reliability of some more recently published taxonomic records for the region: the use of 'predatory journals'; plagiarism; the use of manipulated imagery in more than one description; and taxonomic decision apparently based on expediency.

Available in PDF, EPUB and Kindle. Book excerpt: More than 70% of the earth’s surface is covered by water, making it an ideal and abundant resource for studying species diversity, faunal communities, and ecosystems. India’s massive coastline (5,044 miles) means it plays a major role in housing these faunal communities. Of the 32 animal phyla, 15 are represented in India’s marine ecosystem, covering more than 15,000 species. Marine and coastal ecosystems of India provide supporting services in the form of wide range of habitats. Major ecosystems such as estuaries, mangroves, coral reefs, lagoons, seaweeds and sea grasses serve as nurseries for both inshore and offshore fishes and others, many of which are supposed to be commercially exploited. Marine Faunal Diversity in India describes different marine faunal group ranges from sponges, corals, mollusks, crabs, fishes, reptiles, birds, marine mammals, mangrove fauna and tsunami impact on marine faunal diversity. The chapters, written by reputed experts in their respective fields, illustrate diversity and distribution of marine faunal communities. Key aspects of the ecology and conservation of this important ecosystem are also discussed. Marine Faunal Diversity in India provides marine biologists and related researchers with access to the latest research and field studies from this major region. Provides the latest field research on marine faunal diversity throughout the vast and species-rich Indian region Brings together expertise from top marine biology researchers in the country Covers a diverse array of aquatic environments, including coastal and island areas Discusses conservation ecology of marine faunal groups
Download or read book Treatise on Zoology Anatomy Taxonomy Biology The Crustacea Volume 9 Part C 2 vols written by Peter Castro and published by BRILL. This book was released on 2015-11-24 with total page 1233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, 9C, in two parts, covers the Brachyura. With the publication of the ninth volume in the Treatise on Zoology: The Crustacea, we departed from the sequence one would normally expect. Some crustacean groups, mainly comprising the Decapoda, never had a French version produced, and the organization and production of these “new” chapters began independently from the preparation of the other chapters and volumes. Originally envisioned to encompass volume 9 of the series, it quickly became evident that the depth of material for such a volume must involve the printing of separate fascicles. The new chapters have now been completed, and the production of volume 9 was started while volumes 3 through 8 were (and in part still are) in preparation; with this vol. 9C-I & II this volume 9 is now concluded; vols. 1-5 have also been published and vols. 6-8 are being prepared.

Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: Members of Chrysogorgia Duchassaing & Michelotti, 1864, known as golden corals, are distributed in the deep sea worldwide. Based on specimens obtained from the tropical western Pacific and an integrated morphological-molecular approach, we established a new genus Parachrysogorgia, which includes 13 species separated from Chrysogorgia, and described nine species of Chrysogorgia including three new species C. arboriformis sp. nov., C. cylindrata sp. nov. and C. tenuis sp. nov., and two new combinations of Parachrysogorgia. The genus differs from Chrysogorgia by possessing a bare, sclerite-free area at the base of each tentacle and eight distinct projections beneath tentacles. Chrysogorgia cylindrata sp. nov. is distinguished by a slender bottlebrush-shaped colony in adults, elongate and lobed scales in coenenchyme, and warty and thick sclerites near the polyp mouth area. Chrysogorgia arboriformis sp. nov. is characterized by a tree-shaped colony with a long unbranched stem, slender and thin scales usually with large warts in coenenchyme. Chrysogorgia tenuis sp. nov. can be separated by a broad bottlebrush-shaped colony, long interbranch distance, elongate scales with broad lobes in polyp body wall. In contrast to the intraspecific variation of colony form, branch internodes, branching sequence and polyps, the sclerite forms and arrangement in different parts can be viewed as the most important character to separate Chrysogorgia species. For convenient identification, we divided the Chrysogorgia species into 12 morphological groups and divided Parachrysogorgia into three groups based on their sclerite forms and arrangement. Keywords: Deep sea, morphology, phylogeny, seamount, taxonomy"--Page 3.

Download or read book The Marine Flora and Fauna of Hong Kong and Southern China IV written by Brian Morton and published by Hong Kong University Press. This book was released on 1997-07-01 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following a three-year cycle, an International Workshop on the Marine Flora and Fauna of Hong Kong and Southern China was convened at the Swire Institute of Marine Science of the University of Hong Kong from 2-20 April 1995. Sixteen scientists from six countries and fifteen scientists and students from Hong Kong investigated aspects of the marine flora and fauna of the Cape d'Aguilar proposed marine reserve and the southeastern waters of Hong Kong. The marine flora and fauna of this area of Hong Kong is poorly known and, like others locally, is threatened by pollution. Such broad-based studies of this area of Hong Kong's waters are needed urgently. The Proceedings of the workshop contain thirty-one original research papers dealing with aspects of the taxonomy and ecology of Hong Kong's marine life with particular reference to the Cape d'Aguilar Marine Reserve and the benthic fauna of its territorial waters. The workshop was sponsored by the University of Hong Kong to bring scientists and students together to study the shores and seas around its infant institute of marine science. The success of the workshop is self-evident in the contents and scope of these proceedings. This venture, like the first workshop, convened in 1977, on the shores of the now disastrously polluted Tolo Harbour, is a landmark publication. It is a significant compilation of wide-ranging research papers on an area of Hong Kong that has been, hitherto, little-studied but which will, one day, be of vital conservation interest to local people, if any of the territory's now threatened marine life is to survive.
