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.

Download or read book Additions to a Revision of the Shark Genus Carcharhinus written by J. A. F. Garrick and published by . This book was released on 1985 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Features of the valid nominal species of Aprionodon Gill (isodon Valenciennes) and Hypoprion Müller and Henle (hemiodon Valenciennes, macloti Müller and Henle, and signatus Poey), plus those of a previously unrecognized species here described as Carcharhinus leiodon n.sp., are examined and compared with those of Carcharhinus Blainville. Features studied include morphometrics, vertebral numbers and other vertebral characteristics, tooth numbers, color pattern, and some other aspects of external morphology. It is concluded that on these features C. Leiodon n.sp. is entirely encompassed within the parameters of Carcharhinus, and that, although A. isodon, H. hemiodon, H. macloti, and H. signatus each extend the range of diversity of Carcharhinus in one or more features, A. isodon is not uniquely different from Carcharhinus, and there is no common pattern of difference between the three species of Hypoprion and Carcharhinus. Accordingly, and because the nature of the teeth of Aprionodon and Hypoprion has been found insufficient to warrant generic distinction from Carcharhinus, the genera Aprionodon and Hypoprion are synonymised with Carcharhinus. A diagnosis and description are given for each of the above species. The descriptions include measurements, counts, and line illustrations that show the whole shark in lateral view, underside of head, nostril, and teeth. The geographic distribution is summarized, as are also the meager biological data available on number of embryos, size at birth, size at sexual maturity, and maximum size.

Download or read book Shrimps written by Raymond T. Bauer and published by Springer Nature. This book was released on 2023-04-08 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the biology of decapod shrimps, a group of animals known to most people as a nutritious and tasty food item. Shrimps are amazingly diverse in size, shape, coloration, behavior and natural history. Shrimp fisheries and aquaculture are a vital part of the USA and world economies. These crustaceans are key ecological and food-web components of marine and freshwater habitats. The book synthesizes information on the taxonomic and ecological diversity of shrimps, the structure and function of shrimp anatomy, antifouling adaptations, coloration and camouflage, reproductive biology, sexual systems, mating systems and behavior, life history strategies, symbioses between shrimps and other organisms, shrimp fisheries and aquaculture, as well as the evolution and phylogeny of shrimps. All chapters are written within an adaptational and evolutionary perspective. Important questions about shrimp biology are asked, and hypotheses for testing in future research are proposed. The book is spiced up with personal anecdotes and observations from the author’s research experiences. This book is intended as a comprehensive reference, a “go to” book about the biology of shrimps. The text is scientifically rigorous but written in a style intended for a varied readership. Thus, the book is a valuable resource for budding or working research scientists such as zoologists, aquatic biologists, fisheries and aquaculture professionals, as well as amateur naturalists, aquarium hobbyists and interested laypersons. As the saying goes, “a picture is worth a thousand words,” so that the book is amply illustrated with figures and diagrams.The numerous color plates, composed of photos contributed by expert colleagues, make the world of shrimps come alive.
