Book excerpt: The hard clam, Mercenaria mercenaria, is an important commercial, recreational and ecological inhabitant of coastal bays along the east and gulf coasts of the United States. This title represents the first state of the art summary of existing knowledge of the hard clam by experts in various disciplines.Containing a compendium of literature on the hard clam, comprehensive chapters on various aspects of its biology as well as summaries of knowledge including the gray literature on this economically important species, this volume represents a comprehensive source of biological information for managers and researchers interested in shallow marine and estuarine ecosystems. Research students and managers charged with maintaining coastal ecosystems will also find a wealth of background material.The first synthesis of available information on the mercenaria mercenaria, this title is a response to the needs of individuals involved in hard clam aquaculture and scientists interested in molluscan biology, coastal ocean ecology and similar fields. Over 2300 documents have been synthesized, and chapter authors have added unpublished information as well as new material.

Available in PDF, EPUB and Kindle. Book excerpt: Fifteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical reviews, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that no facet of evolutionary biology-classical or modern-is slighted. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061; Ghillean T.

Download or read book The Evolutionary Biology of the Bivalvia written by Elizabeth Harper and published by Geological Society of London. This book was released on 2000 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bivalves are key components of recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution.

Download or read book Southern Hemisphere Palaeobiogeography of Triassic Jurassic Marine Bivalves written by Susana E. Damborenea and published by Springer Science & Business Media. This book was released on 2012-09-27 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeobiogeography is a complex subject which processes information provided by both Biology and Earth Sciences. It is conceptually and philosophically equivalent to neobiogeography. Nevertheless, its methods are somewhat different, since it is limited by the incompleteness of the fossil record. On the other hand, it has direct access to the time dimension, a key ingredient of organic evolution. Mesozoic benthonic mollusks, and especially bivalves, have a great potential for palaeobiogeographical analysis due to their commonly good preservation, abundance, diversity and high dispersion potential at the larval stage. From a merely descriptive point of view, the analysis of their distribution shows latitudinal gradients and distributional patterns, both at regional and global scales, which are the basis for the recognition of biochoremas or palaeobiogeographical units of different ranks. Moving forward towards a causal palaeobiogeography, these organisms also provide interesting insight into particular biogeographical questions, such as bipolarity and its origin. The evolution in time of the recognized biochoremas can be discussed in relation to palaeoclimas and extinction events. Finally, some of the results obtained from the analysis of the distribution of past bivalve biotas were even used to propose and discuss the development of marine corridors and argue about the distribution of continents in the past.

Download or read book Sea level research a manual for the collection and evaluation of data written by O. van de Plassche and published by Springer. This book was released on 2013-12-20 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: An editorial by Wanless (1982), entitled "Sea level is rising - so what?", tells the case of an executive editor of a major city newspaper, who, when confronted with evi dence for a recent sea-level rise, replied: "That just means the ocean is six inches deeper, doesn't it?". Whether his "so what?" attitude was real or put on to dike a threat of sensation, there is at present a wide and deepening interest in ongoing and future global sea-level change. This interest has grown along with the concern over global warming due to increasing levels of C02 and trace gases. A stage has been reached where investigators of climat- sea-level relationships call for long-term measurement programmes for ice-volume changes (using satellite altimetry) and changes in temperature and salinity of the oceans (ther mal expansion). This manual, however, is primarily concerned with sea level changes in the past, mainly since the end of the last glaciation. Its major objective is to help answer the ques tion: "how?", which, of course, is little else but to assist in the gathering of fuel for the burning question: "why?" Good fuel, hopefully, for the less smoke and ashes, and the more heat and light produced by that fire, the better scientists are enabled to develop a quantitative under standing of past, and hence of future, sea-level changes on different spatial and temporal scales.
