Book Marine Biodiversity of Costa Rica  Central America

Download or read book Marine Biodiversity of Costa Rica Central America written by Ingo S. Wehrtmann and published by Springer Science & Business Media. This book was released on 2008-12-28 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Book Treatise on Zoology   Anatomy  Taxonomy  Biology  The Crustacea  Volume 9 Part B

Download or read book Treatise on Zoology Anatomy Taxonomy Biology The Crustacea Volume 9 Part B written by Frederick Schram and published by BRILL. This book was released on 2012-03-20 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, 9B, covers the infraorders of the Astacidea that were not covered in volume 9A (Enoplometopoidea, Nephropoidea and Glypheidea) as well as the Axiidea, Gebiidea and Anomura. With the publication of this ninth volume in the Treatise on Zoology: The Crustacea, we depart from the sequence one would normally expect. Some crustacean groups never had a French version produced, namely, the orders Stomatopoda, Euphausiacea, Amphionidacea, and Decapoda; the largest contingent of these involved Decapoda – a group of tremendous diversity and for which we have great depth of knowledge. The organization and production of these “new” chapters began independently from the other chapters and volumes. Originally envisioned by the editorial team to encompass volume 9 of the series, it quickly became evident that the depth of material for such a volume must involve the printing of separate fascicles. These new chapters are now nearing completion, and the decision was made to begin publication of volume 9 immediately rather than wait until after volumes 3 through 8 would appear.

Book Deep Sea Pycnogonids and Crustaceans of the Americas

Download or read book Deep Sea Pycnogonids and Crustaceans of the Americas written by Michel E. Hendrickx and published by Springer Nature. 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.

Book Callianassoidea of the World

Download or read book Callianassoidea of the World written by Katsushi Sakai and published by BRILL. This book was released on 2005-11-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the composition of the superfamily Callianassoidea is reassessed and the classification of its included taxa is critically reviewed. The material examined mainly originates from the collections of the Zoological Museum of the University of Copenhagen, and comprises samples from the Galathea Expedition 1950-1952, Dr. Th. Mortensen’s expeditions, including the Java-South African Expedition 1929-1930, and Dr. G. Thorson’s Persian expedition. In all, three of the possibly five families currently incorporated in the Callianassoidea, i.e., Callianassidae, Gourretiidae, and Ctenochelidae, with a total of 12 subfamilies, 20 genera, and 219 species, are represented in this comprehensive revision. The status of the various taxa recognized is placed in the broader context of a re-evaluation of the contents of the infraorder Thalassinidea, in which characters derived from the anatomy of the gastric mill may play a pivotal role. The contents of the book are not only of interest for systematists but also for ecologists and environmental biologists focusing on neritic and benthic biocoenoses, as these mud shrimps are important agents in bioturbation processes of the sea floor.

Available in PDF, EPUB and Kindle. Book excerpt: Decapod crustaceans, shrimps, crabs, prawns and their allies are highly visible and important members of marine environments. They are among the most charismatic of marine animals, inhabiting beaches, rocky shores and the deep sea, hiding under stones, burrowing in the sediment and nestling in among algae and many other microhabitats. However, most are difficult to identify by the specialist and amateur naturalist alike. Marine Decapod Crustacea explains the anatomical features necessary for differentiating taxa and includes diagnoses and identification keys to all 189 families and 2121 genera of marine Decapoda. Many decapods have vivid colours, which are showcased in a selection of spectacular photographs of many representative species. This volume provides an entry to the literature for taxonomists, naturalists, consultants, ecologists, teachers and students wanting to identify local faunas and understand this diverse group

Book Ecology and Conservation of Southeast Asian Marine and Freshwater Environments including Wetlands

Download or read book Ecology and Conservation of Southeast Asian Marine and Freshwater Environments including Wetlands written by A. Sasekumar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major concern among ecologists in and outside the ASEAN region is the degradation of the environment, and the overexploitation of freshwater and marine resources. There is as yet no indication that freshwater and marine resources are being managed on a sustainable basis, and loss of wetlands, whether freshwater swamps or mangrove swamps, is a major problem in the ASEAN region. Reclamation of mangrove swamps for aquaculture and agriculture seems to be a continuous activity here and the status of marine parks should also be examined in the light of recent resort development acitivities on small islands. This volume contains numerous recommendations for the promotion of ecological studies and regional cooperation in marine, freshwater ecology and conservation, with special emphasis on the common water masses like the Strait of Malacca, Gulf of Thailand and the South China Sea.
