This volume presents selected contributions given to the 38th European Marine Biology Symposium, held in Aveiro, Portugal, in September 2003. Understanding the functioning of marine ecosystems is the first step towards measuring and predicting the influence of Man, and to find solutions for the enormous array of problems we face today. This volume is organised according to the four subthemes of the symposium and to issues commonly perceived as relevant by scientists concerned with the study, protection and management of Marine Biodiversity: patterns and processes, assessment, threats and management and conservation. The 32 papers that make up this book represent current research and concerns about Marine Biodiversity in Europe, and will have wide appeal to all those interested in understanding and preserving the marine ecosystems of the world's oceans.

Echinoderms are now considered as a biological and geological model that underlies researches of primary importance. The extent of the contributions made by the International Echinoderm Conferences to various fields of research is attested by the scope covered by presentation at the international conferences. These proceedings contain the complete papers or abstracts of all the presentations and posters presented at the eighth International Echinoderm Conference, held in Dijon, France in September, 1994. Coverage includes: general; extinct classes; crinoids; asteroids; ophiuroids; holothuroids; and echinoids.

This volume provides a refereed selection of the proceedings of the 31st European Marine Biology Symposium, held in St. Petersburg, Russia, in September 1996. State-of-the-art reviews and studies on adaptational processes in marine organisms such as adaptations to fluctuations in salinity, temperature, oxygen and pollutants which are reflected in different types of ecophysiological responses and interactions of marine organisms, including predation, parasitism, intraspecific competition and epibiosys were presented at the symposium proceedings. Research from both eastern and western Europe contributed to this project and during the symposium differences in scientific approaches and views between these two groups became apparent. The contents of this volume reflect these differences. Researchers and students in marine biology as well as those involved in coastal management and environmental studies will find this volume of interest.

Handbook of Methods in Aquatic Microbial Ecology is the first comprehensive compilation of 85 fundamental methods in modern aquatic microbial ecology. Each method is presented in a detailed, step-by-step format that allows readers to adopt new methods with little difficulty. The methods represent the state of the art, and many have become standard procedures in microbial research and environmental assessment. The book also presents practical advice on how to apply the methods. It will be an indispensable reference for marine and freshwater research laboratories, environmental assessment laboratories, and industrial research labs concerned with microbial measurements in water.

Marine biology has always played an important role in biological research, being at the origin of many key advances. To a certain extent, the influence of marine biology on the biological sciences was overshadowed over a period of several years by the remarkable advances that were made using powerful model organisms from terrestrial environments. This situation is now changing again, however, due primarily to spectacular developments in genomic methodologies that have significantly accelerated research in a broad spectrum of marine biology disciplines ranging from biodiversity to developmental biology to biotechnology. The data generated by marine genomics projects have had an impact on questions as diverse as understanding planetary geochemical cycles, the impact of climate change on marine fauna and flora, the functioning of marine ecosystems, the discovery of new organisms and novel biomolecules, and investigation of the evolution of animal developmental complexity. This book represents the first attempt to document how genomic technologies are revolutionising these diverse domains of marine biology. Each chapter of this book looks at how these technologies are being employed in a specific domain of marine research and provides a summary of the major results obtained to date. The book as a whole provides an overview of marine genomics as a discipline and represents an ideal starting point for exploring this rapidly developing domain.

This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders comprising both terrestrial and aquatic taxa. In no case is a taxonomic rev1s10n of any group undertaken, although recommendations for such revisions are included where appropriate, and probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches will be employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Plecoptera and Ephemeroptera or the families Dytiscidae and Culicidae, keys are provided to distinguish all genera and species known to occur in South America. An effort has been made to include every identifiable species so that the user of the key can determine with reasonable certainty whether or not his specimen belongs to a species that has already been described or whether it is one that is not yet known to science. Where feasible, complete keys will be prepared for groups containing both aquatic and terrestrial species that do not encompass an extraordinarily large number of species. This has already been done for the order Collembola.

The Bowhead Whale: Balaena mysticetus: Biology and Human Interactions covers bowhead biology from their anatomy and behavior, to conservation, distribution, ecology and evolution. The book also discusses the biological and physical aspects of the Arctic ecosystem in which these whales live, with careful attention paid to the dramatic changes taking place. A special section of the book describes the interactions of humans with bowheads in past and present, focusing on their importance to Indigenous communities and the challenges regarding entanglement in fishing gear, industrial noise and ship strikes. This volume brings together the knowledge of bowheads in one place for easy reference for scientists that study the species, marine mammal biologists, but, equally important, for everyone who is interested in the Arctic.

This title discusses egg formation, release, and development, variations in life history patterns, population, and fisheries aspects regarding crustaceans.

This book shows how the biological transport, bioaccumulation, disposition, and toxicity of polycyclic aromatic hydrocarbons (PAH) in the aquatic environment are influenced by the ability or inability of organisms to metabolize these environmental pollutants. Written by leading scientists in the fields of PAH metabolism and toxicity in both aquatic and mammalian systems, this book discusses recent advances in the areas of PAH biogeochemistry and bioaccumulation, microbial degradation, enzymes of activation, and detoxication, metabolism of PAH, and laboratory and field studies on carcinogenic/toxic effects. Additionally, important similarities and differences in metabolism of PAH by aquatic and terrestrial organisms are featured. The discussion of bioavailability, metabolism, and subsequent toxic effects should aid in the assessment of the ecological consequences of PAH in the aquatic environment.

This updated and expanded second edition reviews numerous aspects of the marine microbiome and its possible industrial applications. The marine microbiome is the total of microorganisms and viruses in the ocean and seas and in any connected environment, including the seafloor and marine animals and plants. In the first part of the book, diversity, origin and evolution of the marine microorganisms and viruses are discussed. The microbes presented originate from all three domains of life: Bacteria, Archaea, and Eukarya. The second part sheds some light on the different communities: it describes marine habitats and how their inhabitants control biogeochemical cycles. The third part finally examines the microbial ocean as a global system and evaluates methods of utilizing marine microbial resources. Adopting a translational approach, the book connects academic research with industrial applications, making it a fascinating read and valuable resource for microbiologists from both domains.

Ecology and Morphology of Copepods is organized under the following general topics: Behavior, Feeding, Genetics, Horizontal Variations, Morphology, Phylogeny, Reproduction, Seasonal Changes, Vertical Distribution, plus two special sessions on copepods of the genus Acartia and cyclopid/mosquito interactions. The Maxilliped Lecture, given by Dr. Arthur G. Humes of Boston University, clearly established the importance of copepods to the earth's organic diversity. The book consists of selected research articles from the different sections. The articles published here reflect the diverse research interests of copepodologists today, and are distinguished by their high quality. Their impact will ensure that this volume is consulted by a wide range of research biologists.

The world's oceans cover 70% of the earth's surface and are home to a myriad of amazing and beautiful creatures. However, the biodiversity of the oceans is incre- ingly coming under serious threat from many human activities including overfi- ing, use of destructive fishing methods, pollution and commercial aquaculture. In addition, climate change is already having an impact on some marine ecosystems. This book discusses some of the major threats facing marine ecosystems by cons- ering a range of topics, under chapters discussing biodiversity (Chapter 1), fisheries (Chapter 2), aquaculture (Chapter 3), pollution (Chapter 4) and the impacts of increasing greenhouse gas emissions (Chapter 5). It goes on to explore solutions to the problems by discussing equitable and sustainable management of the oceans (Chapter 6) and protecting marine ecosystems using marine reserves (Chapter 7). Presently, 76% of the oceans are fully or over-exploited with respect to fishing, and many species have been severely depleted. It is abundantly clear that, in general, current fisheries management regimes are to blame for much of the widespread degradation of the oceans. Many policy-makers and scientists now agree that we must adopt a radical new approach to managing the seas - one that is precautionary in nature and has protection of the whole marine ecosystem as its primary objective. This 'ecosystem-based approach' is vital if we are to ensure the health of our oceans for future generations.

Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers. The importance of nutrient cycling and retention is discussed from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air--water interfaces, and patch/ecotone structures in watersheds.

Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.

Tidal salt marshes are viewed as critical habitats for the production of fish and shellfish. As a result, considerable legislation has been promulgated to conserve and protect these habitats, and much of it is in effect today. The relatively young science of ecological engineering has also emerged, and there are now attempts to reverse centuries-old losses by encouraging sound wetland restoration practices. Today, tens of thousands of hectares of degraded or isolated coastal wetlands are being restored worldwide. Whether restored wetlands reach functional equivalency to natural' systems is a subject of heated debate. Equally debatable is the paradigm that depicts tidal salt marshes as the great engine' that drives much of the secondary production in coastal waters. This view was questioned in the early 1980s by investigators who noted that total carbon export, on the order of 100 to 200 g m-2 y-1 was of much lower magnitude than originally thought. These authors also recognized that some marshes were either net importers of carbon, or showed no net exchange. Thus, the notion of outwelling' has become but a single element in an evolving view of marsh function and the link between primary and secondary production. The revisionist' movement was launched in 1979 when stable isotopic ratios of macrophytes and animal tissues were found to be mismatched'. Some eighteen years later, the view of marsh function is still undergoing additional modification, and we are slowly unraveling the complexities of biogeochemical cycles, nutrient exchange, and the links between primary producers and the marsh/estuary fauna. Yet, since Teal's seminal paper nearly forty years ago, we are not much closer tounderstanding how marshes work. If anything, we have learned that the story is far more complicated than originally thought. Despite more than four decades of intense research, we do not yet know how salt marshes function as essential habitat, nor do we know the relative contributions to secondary production, both in situ or in the open waters of the estuary. The theme of this Symposium was to review the status of salt marsh research and revisit the existing paradigm(s) for salt marsh function. Challenge questions were designed to meet the controversy head on: Do marshes support the production of marine transient species? If so, how? Are any of these species marsh obligates? How much of the production takes place in situ versus in open waters of the estuary/coastal zone? Sessions were devoted to reviews of landmark studies, or current findings that advance our knowledge of salt marsh function. A day was also devoted to ecological engineering and wetland restoration papers addressing state-of-the-art methodology and specific case histories. Several challenge papers arguing for and against our ability to restore functional salt marshes led off each session. This volume is intended to serve as a synthesis of our current understanding of the ecological role of salt marshes, and will, it is hoped, pave the way for a new generation of research.

Plastic Pollution and Marine Conservation: Approaches to Protect Biodiversity and Marine Life provides comprehensive knowledge on the consequences of plastic waste in marine environments at different levels, ranging from ecological and biological, to social, economic and political. The book synthesizes historical information, gaps in current knowledge, and recent discoveries by illustrating the main stages that made plastics a global issue for ocean ecosystems and their wildlife. Written by international experts on marine pollution, marine biology, and management of environmental resources, this book explores the main topics of marine plastic pollution such as input quantification, polluting sources, ultimate fate, ecological consequences, and more. This an important resource for a wide audience, including marine conservationists, environmental managers, decision-makers, NGOs, private companies, and activists working to combat plastics in our seas and oceans.

The Second International Conference on the Effects of Noise on Aquatic Life will take place in Ireland August 15-20, 2010. The main emphasis of the conference will be on defining the current state of knowledge. However, we will also assess progress in the three years since the First conference. The Second conference will place strong emphasis on recent research results, the sharing of ideas, discussion of experimental approaches, and analysis of regulatory issues.

The 5th International Symposium on Inland Saline Lakes was held at Hotel Titikaka on the shores of that lake, 22-29 March 1991 with participants from 16 countries. 23 papers presented by the participants, plus an additional one reporting a microcosm study on salinity effects, constitute the present volume. The papers cover the wide array of subject matters and scales characteristic of our "interdiscipline" and represent the symposium.

Elements of Marine Ecology, Fifth Edition focuses on marine ecology as a coherent science, providing undergraduate students with an essential foundation of knowledge in the structure and functioning of marine ecosystems. The text reflects ecological groupings such as the pelagic lifestyle vs. the benthic lifestyle. In addition, background oceanographic material, previously in various chapters, is consolidated in the first chapter. The broad definition of ecology is the study of organisms in relation to their surroundings. This book presents marine ecology as a coherent science, providing undergraduate students with an essential foundation of knowledge in the structure and functioning of marine ecosystems. This new edition has been thoroughly revised and updated to meet the needs of today's courses and now includes worldwide examples, all thoroughly updated with brand new chapters.

The effects of disturbed ecosystems, from devastating algal blooms to the loss of whale populations, have demonstrated the vulnerability of the oceans¿ biodiversity. Conservation of marine systems requires knowledge from many different fields in order to understand the complex interactions that threaten those systems. Dynamic Modeling for Marine Conservation provides a method of learning how these systems function, determining how natural and human actions have put them in peril and how we can best influence the marine world in order to maintain biodiversity. The difficulties of research and experimentation in the oceans make computer modeling particularly helpful for marine conservation. Modeling also enables scientists to communicate their findings with managers and others concerned with putting their ideas into practice. The book will demonstrate dynamic modeling through the use of the STELLA modeling program and case studies from marine conservation. After a section devoted to the concepts and tools needed to model marine systems, each chapter introduces background information about a key topic in marine conservation, presents an appropriate model, and discusses the results and implications. Contributors bring a wide range of expertise and experience to a selection of models relevant to real-world conservation problems. All models and a run-time version of the STELLA software are included with the book on a CD-ROM, which is compatible with both Macintosh and Window platforms.

Celebrating its 60th volume (and thus 60 years of publication), this series remains one of the most cited sources in marine science and oceanography. This anniversary volume includes an Editorial discussing the UN Decade of Ocean Science as well as appreciation notes on the work of previous Editor-in-Chiefs. Chapters are authored by leading experts from around the world, including Greece, Chile, Australia, Canada and Australia, while an international Editorial Board ensures continued high quality and rigorous peer review of published articles. The ever increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative reviews summarizing the results of recent research. Supplementary online videos as well as additional Tables and Appendices are available on the Support Tab of the book's Routledge webpage. This volume is available Open Access.
