Download or read book A Guide to the Thalassinidea Crustacea Malacostraca Decapoda of the South Atlantic Bight written by and published by . This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ghost shrimp and mud shrimp in the decapod infraorder Thalassinidea are ecologically important members of many benthic intertidal and shallow subtidal infaunal communities, largely due to the sediment filtration and mixing that result from their burrowing and feeding behavior. These activities considerably modify their immediate environment and have made these cryptic animals extremely interesting to scientists in terms of their behavior, ecology, and classification. Over 20 years ago, seven species of thalassinideans were known from the South Atlantic Bight (Cape Hatteras, NC to Cape Canaveral, FL). During this study, the examination of extensive collections from the National Museum of Natural History (NMNH), the Southeastern Regional Taxonomic Center (SERTC), and regional institutions, resulted in the identification of 14 species of thalassinideans currently known to occur within this region. The family Axiidae is represented by three species: Axius armatus, Calaxius jenneri, and Paraxiopsis gracilimana; the Callianassidae by six: Biffarius biformis, B. cf. fragilis, Callichirus major, Cheramus marginatus, Gilvossius setimanus, and Necallianassa berylae; the Calocarididae by two: Calocaris templemani and Acanthaxius hirsutimanus; and the families Laomediidae, Thomassiniidae, and Upogebiidae are each represented by one: Naushonia crangonoides, Crosniera wennerae, and Upogebia affinis, respectively. An illustrated key is presented for species level identification and supplemental notes on the ecology, distribution, and taxonomy of the species are provided.

This book was released on 2011-02-18 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present section, Callianassida Dana, 1852, has recently been separated from the Thalassinida Dana, 1852; together these two sections constitute the infraorder Thalassinidea within the Decapoda. The section Thalassinida includes one superfamily, Thalassinoidea Dana, 1852, which is not considered herein. The Callianassida include two superfamilies, Axioidea Huxley, 1879 and Callianassoidea Dana, 1852. Those two superfamilies are reviewed according to the presence or absence of a rostral carina; cardiac sulcus(i); cardiac prominence; dorsal oval of the carapace; linea thalassinica; setal rows on carapace, abdomen, tail-fan, and pereiopods; the posterior whip of the maxilla 2 scaphognathite; a dorsal plate or lateral notch on the uropodal exopod; the male Plp1-2; and a median tooth of the prepyloric ossicle. In the present new classification, the section Callianassida thus comprises two superfamilies, Axioidea and Callianassoidea, 19 families including one new family and two families with a new status, 8 subfamilies including one subfam. nov., 116 genera including 41 gen. nov. and 8 genera sensu nov., and 419 species including 12 spp. nov. and 2 nom. nov.
Download or read book Marine Ecology written by Muhammet Turkoglu and published by BoD – Books on Demand. This book was released on 2018-08-01 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth.

Available in PDF, EPUB and Kindle. Book excerpt: An illustrated guide to the sweeping diversity of crustacean larval forms. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Crustaceans—familiar to the average person as shrimp, lobsters, crabs, krill, barnacles, and their many relatives—are easily one of the most important and diverse groups of marine life. Poorly understood, they are among the most numerous invertebrates on earth. Most crustaceans start life as eggs and move through a variety of morphological phases prior to maturity. In Atlas of Crustacean Larvae, more than 45 of the world's leading crustacean researchers explain and illustrate the beauty and complexity of the many larval life stages. Revealing shapes that are reminiscent of aliens from other worlds—often with bizarre modifications for a planktonic life or for parasitization, including (in some cases) bulging eyes, enormous spines, and aids for flotation and swimming—the abundant illustrations and photographs show the detail of each morphological stage and allow for quick comparisons. The diversity is immediately apparent in the illustrations: spikes that deter predators occur on some larvae, while others bear unique specializations not seen elsewhere, and still others appear as miniature versions of the adults. Small differences in anatomy are shown to be suited to the behaviors and survival mechanisms of each species. Destined to become a key reference for specialists and students and a treasured book for anyone who wishes to understand "the invertebrate backbone of marine ecosystems," Atlas of Crustacean Larvae belongs on the shelf of every serious marine biologist.

This book was released on 2021-03-01 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.

Available in PDF, EPUB and Kindle. Book excerpt: In Remarkable Shrimps, Raymond T. Bauer explores the evolution, natural history, biological diversity, and commercial importance of caridean shrimps--a fascinating and colorful group of aquatic organisms that inhabit freshwater and marine environments from the tropics to the poles. The biological diversity of carideans encompasses a remarkable array of adaptations in body form and function, coloration, breeding biology, and mating behavior. Carideans’ important grooming and antifouling adaptations are examined in detail, and Bauer discusses the structural basis of their coloration, the role of color change in concealment, and other forms of camouflage. Reproductive biology and sexual systems, including hermaphroditism and sex change, are reviewed, and Bauer provides evidence for sex pheromones in the attraction of males to females. Seasonal, latitudinal, and depth variation in life history patterns are also analyzed. The symbiotic relationships of shrimps with invertebrates such as corals, sea anemones, and sea urchins and also with fishes are fascinating phenomena of marine ecosystems. Different views on the ancestry and evolutionary history of carideans are evaluated as a stimulus for further work. The status of caridean fisheries and aquaculture is appraised, and shrimp productivity is explained in terms of life history adaptations. Profiling each of the nearly thirty families of caridean shrimps, Bauer writes in an informal style that is nevertheless rich with precise and useful references. Over one hundred figures and 11 plates with 70 color and half-tone photographs accompany the text. Extensive fieldwork is showcased in life history studies on shrimps, employing both behavioral observations using time-lapse video and experimental work to test hypotheses on mating strategies.
Download or read book The Biology of Decapod Crustacean Larvae written by Klaus Anger and published by CRC Press. This book was released on 2001-06-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.

Download or read book Environmental Adaptations written by F. John Vernberg and published by Elsevier. This book was released on 2014-04-24 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Adaptations examines the dynamic interaction between an organism and its external environment in order to emphasize the adaptive significance of its responses. Focusing on the adaptations of crustaceans, it bridges the gap between other volumes in the series which deal in detail with the functional machinery of crustaceans and those dealing with ecological, taxonomic, behavioral, and applied subjects. This book is divided into seven chapters. The first two chapters highlight the range of respiratory responses exhibited by crustaceans when subjected to various environmental factors. Chapter 3 summarizes the mechanisms by which crustaceans take up energy and food from the environment under fluctuating conditions. It also reviews the assimilation efficiencies of crustaceans and the predator-prey interaction. Chapter 4 deals with ionic and osmoregulation from the view of its interaction with the environment. It emphasizes the adaptive nature of chemical regulation that enables various crustaceans to inhabit waters ranging from hypersaline ponds to fresh water. Chapter 5 discusses how the various species are reproductively adapted to generate offspring in the tremendous diversity of habitats occupied by crustaceans. The last two chapters report on the specific adaptations of crustaceans to terrestrial and freshwater habitats. This book is a valuable source for zoologists, paleontologists, ecologists, physiologists, endocrinologists, morphologists, pathologists, and fisheries biologists, and an essential reference work for institutional libraries.
Download or read book Detecting Ecological Impacts written by Russell J. Schmitt and published by Academic Press. This book was released on 1996-01-17 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detecting Ecological Impacts: Concepts and Applications in Coastal Habitats focuses on crucial aspects of detecting local and regional impacts that result from human activities. Detection and characterization of ecological impacts require scientific approaches that can reliably separate the effects of a specific anthropogenic activity from those of other processes. This fundamental goal is both technically and operationally challenging. Detecting Ecological Impacts is devoted to the conceptual and technical underpinnings that allow for reliable estimates of ecological effects caused by human activities. An international team of scientists focuses on the development and application of scientific tools appropriate for estimating the magnitude and spatial extent of ecological impacts. The contributors also evaluate our current ability to forecast impacts. Some of the scientific, legal, and administrative constraints that impede these critical tasks also are highlighted. Coastal marine habitats are emphasized, but the lessons and insights have general application to all ecological systems.
