Available in PDF, EPUB and Kindle. Book excerpt: The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels are unknown. The preservation of these ecosystemic services needs a clear understanding of their complexity. The role of research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for the local populations that use it but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems need innovative and diverse methods. For all these reasons, the aim of this book is to bring out a general view on the function of ecosystems, modelling, sampling strategies, invading species, the response of organisms to modifications, the carbon dynamics, the mathematical models and theories that can be applied in diverse conditions.

Download or read book The living marine resources of the Eastern Central Atlantic Volume 4 Bony fishes part 2 Perciformes written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-15 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume field guide covers the species of interest to fisheries of the major marine resource groups exploited in the Eastern Central Atlantic. The area of coverage includes FAO fishing area 34 and part of 47. The marine resource groups included are bivalves, gastropods, chitons, cephalopods, stomatopods, shrimps, lobsters, crabs, hagfishes, sharks, batoid fishes, chimaeras, bony fishes and sea turtles. The introductory chapter outlines the environmental, ecological, and biogeographical factors influencing the marine biota, and the basic components of the fisheries in the Eastern Central Atlantic. Within the field guide, the sections on the re source groups are arranged phylogenetically according to higher taxonomic levels such as class, order, and family. Each resource group is introduced by general re marks on the group, an illustrated section on technical terms and measurements, and a key or guide to orders or families. Each family generally has an account summarizing family diagnostic characters, bi o logical and fisheries in formation, notes on similar families occur ring in the area, a key to species, a check list of species, and a short list of relevant literature. Families that are less important to fisheries include an abbreviated family account and no de tailed species in formation. Species in the important families are treated in detail (arranged alphabetically by genus and species) and include the species name, frequent synonyms and names of similar specie s, an illustration, FAO common name(s), diagnostic characters, biology and fisheries in formation, notes on geo graphical distribution, and a distribution map. For less important species, abbreviated accounts are used. Generally, this includes the species name, FAO common name(s), an illustration, a distribution map, and notes on biology, fisheries, and distribution. Each volume concludes with its own index of scientific and common names.

Available in PDF, EPUB and Kindle. Book excerpt: The Early Life History (ELH) of marine fishes in Fishing Area 31, which includes the western central North Atlantic, Caribbean Sea, and the Gulf of Mexico, has remained incomplete over the years. This certainly wasn't because of any lack of interest, but rather a lack of a comprehensive merging of studies that would provide a broad understandi

Download or read book Inshore Fishes of Britain and Ireland written by Lin Baldock and published by Princeton University Press. This book was released on 2023-04-25 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: A beautifully illustrated photographic identification guide to the common marine fish found around Britain and Ireland—ideal for divers, snorkellers, and natural history enthusiasts Fish are a colourful and important part of inshore marine life, much admired by divers and snorkellers. But it can be difficult to accurately identify and record these quick-moving animals underwater. This authoritative, beautifully illustrated photographic guide offers a practical, easy-to-use approach for identifying the fish species commonly seen in the waters around Britain and Ireland, as well as a few vagrant and interesting rare species. The book’s concise text explains how fish can be identified underwater, and is accompanied by numerous photographs of each species in its natural environment and diagrams illustrating key features. The book also clearly indicates the cases when underwater species identification is more difficult. Published in association with the UK’s Marine Conservation Society, the book makes an invaluable addition to the series of marine photographic titles of Seasearch, a species recording project for volunteer sports divers. Features individual descriptions of more than 150 species, with information on size, depth range, habitat and distribution in the Seasearch guide icon format Illustrates every species in its natural underwater environment Emphasises key identification features and possible confusion species Includes a “confidence guide” distinguishing between easily recognisable species and those requiring closer examination Features longer sections highlighting interesting species, behaviours and other topics Provides information on protected species, taxonomy, shifting distributions and conservation status

Download or read book The Larvae of Indo Pacific Coastal Fishes written by Jeffrey Leis and published by BRILL. This book was released on 2021-10-01 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume in the Fauna Malesiana book series gives an extensive overview of the larval development of 124 families of fishes, many of them of importance for both fishery and from ecological perspectives. The families that are described originate from the center of global marine biodiversity: the tropical Indo-Pacific Oceans, a region rich in coral reefs, as well as mangrove, estuarine, and coastal shelf habitats. The identification guide not only documents the ontogeny of these fishes but also provides the means to identify these extraordinarily diverse larvae to the level of family. The book offers a wealth of instructive and detailed figures and illustrations (219 plates, each consisting of approximately 4 figures) for enabling the identification of these families and their larval specialization.

Available in PDF, EPUB and Kindle. Book excerpt: Plans for an International Symposium on the Early Life History of Fish were first discussed in 1967 at the F. A. O. Advisory Committee on Marine Resources Research {A. C. M. R. R. }. It was considered that studies on fish eggs and larvae were of value in estimating the size of fish stocks, in appraising the stock-recruitment relationship, and in helping to answer questions on the systematics and taxonomy of fish. An A. C. M. R. R. Working Party recommended in 1969 that a Symposium should be held and after discussion with the International Associa tion of Biological Oceanography {I. A. B. O. } Dr. J. H. S. Blaxter of the Scottish Marine Biological Association {S. M. B. A. } agreed to con vene the meeting with the help of a steering committee. Various in ternational agencies were interested in the meeting and agreed to sponsor it in various ways. These agencies included F. A. O. , I. A. B. O. , the International Council for the Exploration of the Sea {I. C. E. S. } and the Scientific Committee for Oceanic Research {S. C. O. R. }. In the final event F. A. O. supported the meeting by publishing the abstracts beforehand, providing travel funds for participants and publishing a report after the meeting. I. A. B. O. and S. C. O. R. provided travel funds and the Royal Society of London and S. M. B. A.

This book was released on 1972 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish larvae belonging to 24 families and the suborder Blennioidea were collected from Puget Sound and the Pacific Ocean off British Columbia, Washington, and Oregon during April and May 1967. All families and the Blennioidea were present in oceanic waters, but only 13 families and the Blennioidea were present in Puget Sound. The most abundant families in the oceanic area were Scorpaenidae, Myctophidae, and Pleuronectidae, whereas in Puget Sound the most abundant families were Gadidae, Pleuronectidae, and Scorpaenidae. Variations in composition and numbers of larvae in the catch were associated with area, water depth, and water temperature, and time of day at which the collections were made.

Download or read book Fish atlas of the Celtic Sea North Sea and Baltic Sea written by Henk J.L. Heessen and published by BRILL. This book was released on 2023-09-14 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atlas presents a unique set of abundance data to describe the spatial, depth, size, and temporal distribution of demersal and pelagic fish species over an extensive marine area, together with accounts of their biology. A large number of pictures, graphs and distribution maps illustrate the text. By largely avoiding - or at least explaining - scientific terms and providing extensive references, the book should be useful for both laymen and scientists. The quantitative information on some 200 fish taxa is derived from 72,000 stations fished by research vessels during the period 1977-2013. The area covers the northwest European shelf from west of Ireland to the central Baltic Sea and from Brittany to the Shetlands. Although the surveys extend beyond the shelf edge, only taxa reported at least once in waters less than 200 m are included. Typical deep-water species and typical fresh-water species are excluded. We hope this publication will contribute to gaining a better understanding of the ocean ecosystems.
