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.
Download or read book A Guide to and Checklist for the Decapoda of Namibia South Africa and Mozambique Volume 3 written by W. D. Emmerson and published by Cambridge Scholars Publishing. This book was released on 2017-06-20 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decapods are a culmination of nearly 600 million years of Crustacean evolution, during which time they have radiated into a variety of superfamilies, families, genera and species which occupy a variety of niches from fresh mountain streams to the abysses of the oceans. This book will fill a gap in the current literature on southern African decapods. Since Barnard published his Descriptive Catalogue of South African Decapod Crustacea in 1950, there have been numerous additions and name changes. This publication updates the taxonomy, and includes ecological and fisheries information. In addition, Kensley’s (1981) distributional checklist for the region has been updated and includes large numbers of new species and records for the region, bringing the total number of decapod to over 1000 species. Although not exhaustive, 262 species are featured, some of which are beautiful, some have commercial or artisinal value, both for consumption and the aquarium, and some have important ecological functions, while others are rare or interesting. For each species there is a photograph, synonymies, common names, a description, ecological information and name derivation (etymology). All the decapod families found in South Africa are described, some new, along with chapters on decapod research history in southern Africa, commercial and artisinal food value of decapods, biodiversity and future research direction. The book is arranged systematically, as taxonomy is based on phylogeny, starting with the earliest forms and progressing to the most derived and advanced forms, and will serve to stimulate interest and future research into southern Africa’s rich decapod biodiversity, especially at a time when biodiversity itself is threatened by global warming, coral bleaching and habitat loss. It will appeal to people interested in Decapoda, including academics, scholars, students, fishermen, aquarists, aquaculturists, recreational snorkel and SCUBA divers, as well as those interested in conservation, biodiversity, management and governance.
Download or read book Systema Porifera written by John N.A. Hooper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1779 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.

Download or read book Phosphate Deposits of the World Volume 3 Neogene to Modern Phosphorites written by P. J. Cook and published by Cambridge University Press. This book was released on 1986 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine phosphorites, the principal raw material for phosphatic fertilizers, do not occur uniformly through time and space. The origin of these unusual sedimentary rocks appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene, one of the major and most recent phosphogenic periods throughout the geologic record. In addition, an oceanographic perspective is given by investigations of modern oceanic environments where phosphorites are presently forming. Together, the geologic and marine approaches provide a complete outlook on this important mineral resource. This book is the third of four reference volumes which together cover the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the project's existence.
