This book was released on 2012-12-06 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction This book contains papers given at a NATO Advanced Research Institute (A.R.I.) held at Caiscais, Portugal, in November, 1981. The subject of the A.R.I. was marine heterotrophy; this is defined as the process by which the carbon autotrophically fixed into organic compounds by photosynthesis is transformed and respired. Obviously all animals and many microbes are heterotrophs but here we will deal only with the microbes. Also, we restricted the A.R.I. primarily to microbial heterotrophy in the water column even though we recognize that a great deal occurs in sediments. Most of the recent advances have, in fact, been made in the water column because it is easier to work in a fluid, apparently uniform medium. The reason for the A.R.I. was the rapid development of this subject over the past few years. Methods and arguments have flourished so it is now time for a review and for a sorting out. We wish to thank the NATO Marine Science Committee for sharing this view, F. Azam, A.-L. Meyer-Reil, L. Pomeroy, C. Lee, and B. Hargrave for organizational help, and H. Lang and S. Semino for valuable editing aid.

Download or read book Protozoa and Their Role in Marine Processes written by P.C. Reid and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the summer of 1988, under NATO sponsorship, approximately 80 scientists lived and worked together in Plymouth for two weeks to evaluate the ecological role of protozoa in the sea. Through the convivial surroundings, close working conditions and special facilities that had been brought together for NATO ASI 604/87 a 'melting pot' of ideas was formed, which stimulated the multidisciplinary creativity which is expressed in this book and in a second series of papers which will be published in Marine Microbial Food Webs under the title - "Protozoa and their Role in Marine Microbial Food Webs". Discussions of the role of protozoa in the microbial food web, in the cycling of carbon and nitrogen and the extent to which this web acts as a link or sink to metazoa in the water column were major themes of the ASI. Structured sessions covering oral and poster presentations, field work, model 1 ing, laboratory practicals and demonstrations of techniques such as image analysis and flow cytometry, formed the core of the meeting. Participants took part enthusiastically in the practical sessions developing new concepts and obtaining new insights into their work. The practicals included a 'protozoo' and some beautiful films and videos. Field excursions were made to a range of sites including a unique marine sewage farm at Looe in Cornwall, (Jones this volume). Interactive workshops allowed scientists with no modelling experience to input their results to three simulation models and a flow analysis package.

Download or read book Ecological Studies in the Coastal Waters of Mauritania written by W.J. Wolff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on the ecology of Mauritanian coastal waters and in particular the Banc d'Arguin, allows us to understand the functioning of this remarkable coastal wetland. Major questions concern the interaction between the Banc d'Arguin ecosystem on the one hand and the adjoining systems of the open ocean with its intensive upwelling phenomena and the Sahara desert on the other. Is the Banc d'Arguin ecosystem relatively isolated from its surroundings and does it function as a tropical pocket in a more temperate surrounding, as suggested by Sevrin-Reyssac (1983); or does it interact with both the Sahara and the Atlantic Ocean? At the Banc d'Arguin, the area between the estuarine parts and the open ocean is extremely shallow and largely uncharted. Large research vessels cannot penetrate the shallows, whereas small vessels are often unable to negotiate the outer part of the shallow area due to rough weather conditions. Hence, separate teams report on work at the seaward side of this shallow sill and at the landward side. In addition, other teams address different questions, such as the productivity of the seagrass beds and the benthic fauna, the number of birds spending the summer at the Banc d'Arguin, and the distribution of several taxonomic groups of flora and fauna.
Download or read book Biogeochemical Processes at the Land Sea Boundary written by P. Lasserre and published by Elsevier. This book was released on 1986-09-01 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an intuitive belief among scientists that each estuary or lagoon is unique and different. Similarities do exist, however, and this book attempts to highlight some common properties and perhaps some innovative views on biogeochemical processes, and biological fluxes which are of central concern in the understanding of the land-sea boundary. The contents are based upon lectures given at a Seminar organised as the scientific component of the 17th General Meeting of SCOR, held at the Station Biologique de Roscoff, France, on 22-24 October 1984. The original lectures have been substantially extended and revised in order to give a fuller treatment of the subject. The contributions identify important processes influencing (I) Behaviour of chemical species, (II) Nutrient cycling and mechanisms of organic transformations and (III) Uptake of trace elements by living systems. The connection between terrestrial and oceanic systems is a functional one and the consequences of this linkage on the very large variety of coastal systems are profound. It is widely recognized that many of the major processes which influence the biological properties and chemical forms of elements, and their biogeochemical cycles in the ocean occur at the land-sea boundary, especially in estuaries, coastal lagoons, the coastline and the shelf. Over 80% of living systems and their fisheries take place in near shore waters and the consequential production of organic matter produced triggers off the high level of activity. Over the last fifteen years, there has been considerable stimulus to provide framework to evaluate the interactions and effects of human activities. The rich assemblage of tables and figures and of literature citations contained in the chapters provides an excellent basis for in-depth investigations. Oceanographers, limnologists, aquatic chemists, marine biologists, and environmental specialists will find this book highly valuable reading for advanced research and training purposes.

Download or read book Deep Subsurface Microbiology written by Andreas Teske and published by Frontiers Media SA. This book was released on 2015-07-01 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep subsurface microbiology is a highly active and rapidly advancing research field at the interface of microbiology and the geosciences; it focuses on the detection, identification, quantification, cultivation and activity measurements of bacteria, archaea and eukaryotes that permeate the subsurface biosphere of deep marine sediments and the basaltic ocean and continental crust. The deep subsurface biosphere abounds with uncultured, only recently discovered and – at best - incompletely understood microbial populations. In spatial extent and volume, Earth's subsurface biosphere is only rivaled by the deep sea water column. So far, no deep subsurface sediment has been found that is entirely devoid of microbial life; microbial cells and DNA remain detectable at sediment depths of more than 1 km; microbial life permeates deeply buried hydrocarbon reservoirs, and is also found several kilometers down in continental crust aquifers. Severe energy limitation, either as electron acceptor or donor shortage, and scarcity of microbially degradable organic carbon sources are among the evolutionary pressures that have shaped the genomic and physiological repertoire of the deep subsurface biosphere. Its biogeochemical role as long-term organic carbon repository, inorganic electron and energy source, and subduction recycling engine continues to be explored by current research at the interface of microbiology, geochemistry and biosphere/geosphere evolution. This Research Topic addresses some of the central research questions about deep subsurface microbiology and biogeochemistry: phylogenetic and physiological microbial diversity in the deep subsurface; microbial activity and survival strategies in severely energy-limited subsurface habitats; microbial activity as reflected in process rates and gene expression patterns; biogeographic isolation and connectivity in deep subsurface microbial communities; the ecological standing of subsurface biospheres in comparison to the surface biosphere – an independently flourishing biosphere, or mere survivors that tolerate burial (along with organic carbon compounds), or a combination of both? Advancing these questions on Earth’s deep subsurface biosphere redefines the habitat range, environmental tolerance, activity and diversity of microbial life.

Download or read book Aquatic Microbial Ecology and Biogeochemistry A Dual Perspective written by Patricia M. Glibert and published by Springer. This book was released on 2016-07-25 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights perspectives, insights, and data in the coupled fields of aquatic microbial ecology and biogeochemistry when viewed through the lens of collaborative duos – dual career couples. Their synergy and collaborative interactions have contributed substantially to our contemporary understanding of pattern, process and dynamics. This is thus a book by dual career couples about dual scientific processes. The papers herein represent wide-ranging topics, from the processes that structure microbial diversity to nitrogen and photosynthesis metabolism, to dynamics of changing ecosystems and processes and dynamics in individual ecosystems. In all, these papers take us from the Arctic to Africa, from the Arabian Sea to Australia, from small lakes in Maine and Yellowstone hot vents to the Sargasso Sea, and in the process provide analyses that make us think about the structure and function of all of these systems in the aquatic realm. This book is useful not only for the depth and breadth of knowledge conveyed in its chapters, but serves to guide dual career couples faced with the great challenges only they face. Great teams do make great science.
Download or read book Physiological Responses of Marine Biota to Pollutants written by John F Vernberg and published by Elsevier. This book was released on 2012-12-02 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological Responses of Marine Biota to Pollutants contains the proceedings of a symposium entitled ""Pollution and Physiology of Marine Organisms"" held in Connecticut in November 1975. It explores the influence of pesticides, polychlorinated biphenyls (PCBs), petroleum products, and heavy metals on the physiology of marine species, such as fish, crabs, shrimps, lobsters, and mussels. More specifically, it looks at the functional mechanisms underlying the response of marine organisms to pollutants that act either alone or in combination with other pollutants and/or ""normal"" environmental factors. Comprised of five parts encompassing 27 chapters, this volume begins with an overview of pesticides and PCBs and their effects on marine organisms, including those of malathion on the development of crabs and of PCBs on feral fish. It proceeds with a discussion of heavy metals, such as methylmercury, selenium, cadmium and cadmium chloride, and chromium; and an explanation of how petroleum hydrocarbons affect estuarine fish embryos, pink salmon fry, marine fish, Mytilus californianus, Mya arenaria, Mytilus edulis, and plankton. The reader is also introduced to the synergistic effects of exposure to temperature and chlorine on young-of-the-year estuarine fishes, the effects of DDT and mirex singly and in concert on Adinia xenica, the role of temperature in the physiology of bivalves, physiological responses of crustacean larvae to temperature, use of the heterotrophic potential assay as an indicator of environmental quality, and how the mud crab (Rhithropanopeus harrisii) is affected by juvenile hormone mimics. Marine scientists, ecologists, and students will find this book extremely useful.
