This book was released on 2009 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Primnoidae consists of 36 genera, 7 subgenera, and 233 valid species, making it the fourth largest octocorallian family. Species occur in all ocean basins, especially the Antarctic, at depths of 8-5850 m, making primnoids the deepest-living gorgonacean octocorals. Primnoids are common and characteristic of seamounts and deepwater coral banks, often providing habitat for other marine life and serving as proxies for isotopic analyses to determine paleotemperatures. Diagnoses of the primnoid genera and subgenera are based primarily on their type species, and specimens are illustrated by means of scanning electron microscopy, often using stereo images to allow better appreciation of the topology and interconnection of the calycular sclerites. A history of the higher classification of the family is given. Each genus is briefly discussed, and also included are a synonymy of pertinent references, a summary of the geographic and bathymetric ranges, and the deposition of the type specimens of the type species. Four new genera, two new subgenera, one new species, and seven new combinations are proposed. A list of the 233 valid species and the 14 infraspecific taxa is provided along with the purported junior synonyms. An indented dichotomous key is provided for identification of the genera and subgenera. Phylogenetic analysis of the genera and subgenera was performed using 27 morphological characters comprising 94 character states. The cladogram does not consistently support the conventional arrangement of genera into five subfamilies, thus this classification is not followed herein. The origin of the primnoids is inferred to be from an ancestor living in the Antarctic."--Publisher's website.
Download or read book A Revision of the Primnoidae Octocorallia Acyonacea from the Aleutian Islands and Bering Sea written by Stephen Douglas Cairns and published by . This book was released on 2011 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nineteen of the 31 octocoral species (61%) known from the Aleutian Islands belong to family Primnoidae, which form large deep-water (9-2,514 m) colonies providing habitat for one of the most productive fisheries in the North Pacific. These 19 species are described or redescribed and figured unless recent descriptions have been published. Eight new species are described, two in the genus Thouarella and six in the genus Plumarella. These two genera are redefined and differentiated by emphasizing the nature (keeled or not) of the inner side of their marginal scales and the inner side's articulation or lack thereof with the outer surface of the underlying opercular scales. Dicholaphis is proposed as a new subgeneric rank of the genus Plumarella, characterized by having polyps arranged on all sides of its branchlets, not on alternate opposite sides. A key is provided for the eight species of Aleutian Plumarella, and all 35 valid species in the genus are listed, including three new combinations: P. superba, P. abietina, and P. recta. A history of the Aleutian primnoids is recounted. Six primnoid species are reported from the Bering Sea, all of which also occur in the Aleutian Islands. Two-thirds of the Aleutian-Bering Sea primnoids are endemic to this region.
Download or read book An Annotated Checklist of the Marine Macroinvertebrates of Alaska written by David Thomas Drumm and published by . This book was released on 2016 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: A current and comprehensive species list of marine invertebrates of Alaska is essential for effective management of living marine resources, sustainable fisheries, conservation of vulnerable ecosystems, and advancement of our knowledge of biodiversity and ecosystem function. Furthermore, the most current checklist available to resource managers and scientists is quite dated and limited in that it only includes the marine invertebrates of the southern coast of Alaska to California. Since that checklist was published, many new species have been described, many range extensions have been discovered, and considerable changes in higher-level systematics have been made. The checklist that we have compiled lists 3708 species and presents for each species the currently accepted scientific name and its significant synonyms, common names, type localities, geographic and depth distributions, a general statement of abundance in Alaska when known (e.g., rare, uncommon, common, abundant), and general remarks. It includes species recorded in the marine waters of Alaska from the intertidal zone, continental shelf, and upper continental slope to abyssal depths, from the Beaufort Sea at the Arctic border with Yukon, Canada; the eastern Chukchi Sea, the eastern Bering Sea, the Aleutian Islands to the western border with Russia; and the Gulf of Alaska to Dixon Entrance at the southern border with British Columbia. Sound and reliable taxonomic identifications are necessary to monitor and predict changes in the distribution and abundance of marine species. The current status and future direction of the study of Alaskan marine invertebrate biodiversity are briefly discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Marine ecosystems, a very wide topic, includes many different processes, groups of organisms and geographical peculiarities. The objective of this book is to present various topics of great importance for understanding the marine ecosystems, what they are, how they work and how we can model them in order to forecast their behaviour under changing conditions.

Available in PDF, EPUB and Kindle. Book excerpt: What do we know about Mediterranean Cold (Deep)-Water coral ecosystems? In this book, specialists offer answers and insights with a series of chapters and short papers about the paleoecology, biology, physiology and ecology of the corals and other organisms that comprise these ecosystems. Structured on a temporal axis—Past, Present and Future—the reviews and selected study cases cover the cold and deep coral habitats known to date in the Mediterranean Basin. This book illustrates and explains the deep Mediterranean coral habitats that might have originated similar thriving ecosystems in today’s Atlantic Ocean.

This book was released on 2019-08-09 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document has been prepared by the Food and Agriculture Organization of the United Nations (FAO), in accordance with a request from CITES (CoP Decision 17.191 on Precious corals, for consideration at the 30th meeting of the Animals Committee). The report concerns precious (red, pink, white and black) coral species within the hexacoral order Antipatharia, and the octocoral family Coralliidae. According to the requirements of CITES Decision 17.191, the study considers all available data and information on the biology, population status, use and trade in each species, including the identification of gaps in such data and information. It contains information on the management and harvest regulation schemes for these coral species, with the aim of considering the effectiveness of their management and conservation. The report intends to inform the CITES parties of the status of the management and trade of precious corals, in order to provide guidance on the actions needed to enhance the conservation and sustainable use of precious corals.
