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. Keywords: Marine biodiversity, Indian Ocean, Sri Lanka, Maldives, Western Myanmar, checklist, species, sea fans, octocorals"--Page 7.

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

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 Distribution and Biodiversity of Singapore Gorgonians sub class Octocorallia a Preliminary Survey written by Nigel K. C. Goh and published by . This book was released on 1991 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preliminary surveys of the gorgonian fauna of Singapore show the existence of 6 families, comprising at least 9 genera and 18 species. Studies show that the distribution of this fauna is closely related to the availability of a suitable substrate for settlement and growth. In addition, the greatest number of gorgonians, in terms of abundance and species richness, is found on the lower slopes and bottoms of the reefs in Singapore. Diversity and equitbility values for Singapore reefs indicate a temporally predictable but stressful environment. [Authors' abstract].

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a broad panorama of the current status of research of invertebrate animals considered belonging to the phylum Cnidaria, such as hydra, jellyfish, sea anemone, and coral. In this book the Cnidarians are traced from the Earth’s primordial oceans, to their response to the warming and acidifying oceans. Due to the role of corals in the carbon and calcium cycles, various aspects of cnidarian calcification are discussed. The relation of the Cnidaria with Mankind is approached, in accordance with the Editors’ philosophy of bridging the artificial schism between science, arts and Humanities. Cnidarians' encounters with humans result in a broad spectrum of medical emergencies that are reviewed. The final section of the volume is devoted to the role of Hydra and Medusa in mythology and art.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most serious consequences of global climate change for coral reefs is the increased frequency and severity of mass coral bleaching events and, since the first edition of this volume was published in 2009, there have been additional mass coral bleaching events. This book provides comprehensive information on the causes and consequences of coral bleaching for coral reef ecosystems, from the genes and microbes involved in the bleaching response, to individual coral colonies and whole reef systems. It presents detailed analyses of how coral bleaching can be detected and quantified and reviews future scenarios based on modeling efforts and the potential mechanisms of acclimatisation and adaptation. It also briefly discusses emerging research areas that focus on the development of innovative interventions aiming to increase coral climate resilience and restore reefs.
