This volume contains the papers and abstracts of the posters given at the symposium on Long-term Changes in Coastal Benthic Communities organized by the Commission of the European Communities in Brussels, Belgium from 9 till 12 December 1985. The organization of this symposium came to conclude five years of activities in the COST 647 project on Coastal Benthic Ecology, the rationale of which is explained in the foreword by B. F. Keegan. The importance of this volume is that for the first time special attention is given to long-term data series of relevant biological variables collected in different marine benthic habitats. Many of the data presented here are the result of years of careful data collection by some of the leading scientists in the field of benthic ecology. Some of the series, such as the Macoma balthica data from the Wadden Sea or the macrofauna data from Loch Linnhe, to name just those two, are already classics in the marine biological literature. Other data were collected in the framework of a monitoring programme and are now analyzed for the first time in the different perspective of the COST 647 project. Several papers are from related fields where they represent well known case studies; they were chosen in order to see how problems have been tackled elsewhere.

Against a background of extensive multi-disciplinary oceanographic investigations over a number of years, together with the long-term establishment of a Society and Institute, extensive information is available from studies undertaken in the estuarine and coastal waters of the Basque Country. The present authors gained access to unpublished literature and reports which, together with a synthesis of internationally-refereed papers, provide a series of scientific overviews of particular subject areas. Teams of researchers (from Basque Institutes and Universities) combine to present the present 'state of knowledge', within a global context, of processes ranging from sub-seabed to air-sea interaction - incorporating data on the associated biology (including fisheries) and pollutant sources and levels. The latter are compared with regional, national and European legislation. The volume is divided into various sections: Introduction; Geography and Oceanography; Chemical Oceanography and Water Quality; Sediment Characteristics, Quality and Chemistry; Biomonitoring; Communities and Ecology; and Overall Assessment. The topics covered include: an historical review of marine research; the impact of human activities, during past centuries; geology, geomorphology and sediments; climate and meteorology; marine dynamics; hydrography; water mass characteristics; contaminants in the waters; microbiological quality; sedimentological characteristics; contaminants in sediments; biomonitoring of heavy metals and organic components, at tissue organism level and using cellular and molecular biomarkers; bacterioplankton and phytoplankton communities; zooplankton communities; benthic communities; seabirds; biodiversity and conservation; recovery of benthic communities; the polluted systems; and assessment of human impacts. On the basis of these syntheses, future challenges for marine research in the Basque Country are identified, in terms of a 'Research Agenda'. This comprehensive text, relating to estuarine, coastal and oceanographic processes at wide-ranging spatial and temporal scales in the southern Bay of Biscay, will be of interest to researchers, engineers and legislators - on a regional basis and within a world-wide perspective.

Evaluating Climate Change Impacts discusses assessing and quantifying climate change and its impacts from a multi-faceted perspective of ecosystem, social, and infrastructure resilience, given through a lens of statistics and data science. It provides a multi-disciplinary view on the implications of climate variability and shows how the new data science paradigm can help us to mitigate climate-induced risk and to enhance climate adaptation strategies. This book consists of chapters solicited from leading topical experts and presents their perspectives on climate change effects in two general areas: natural ecosystems and socio-economic impacts. The chapters unveil topics of atmospheric circulation, climate modeling, and long-term prediction; approach the problems of increasing frequency of extreme events, sea level rise, and forest fires, as well as economic losses, analysis of climate impacts for insurance, agriculture, fisheries, and electric and transport infrastructures. The readers will be exposed to the current research using a variety of methods from physical modeling, statistics, and machine learning, including the global circulation models (GCM) and ocean models, statistical generalized additive models (GAM) and generalized linear models (GLM), state space and graphical models, causality networks, Bayesian ensembles, a variety of index methods and statistical tests, and machine learning methods. The reader will learn about data from various sources, including GCM and ocean model outputs, satellite observations, and data collected by different agencies and research units. Many of the chapters provide references to open source software R and Python code that are available for implementing the methods.

“Intertidal ecologists have been struggling with how to adequately monitor the tremendous diversity and heterogeneity of rocky shores for decades. Finally three of the most experienced and established people in the field have done it. Monitoring Rocky Shores will serve as THE central reference guide for scientists intent on understanding the complexities of intertidal ecology.”—John Pearse, coauthor of Animals Without Backbones “The incredibly high taxic, morphological, ecological, as well as biotic diversity of rocky shores makes them ideal sites for ecological studies; however this same diversity also presents innumerable challenges. Monitoring Rocky Shores is long overdue in helping investigators tackle these innumerable challenges. This book provides a broad and important introduction to the habitat, the animals, the methods, and the analyses required constructing informed hypotheses and scenarios for life on rocky shores.”—David R. Lindberg, Museum of Paleontology, co-editor of Phylogeny and Evolution of the Mollusca

Pollution of estuaries and coastal marine waters is of profound ecological and societal importance. These coastal environments serve as critical habitat for a multitude of organisms and are of great commercial and recreational value to humans. Designed to meet the research, monitoring, and assessment needs of scientists, administrators, planners, and managers, Pollution Impacts on Marine Biotic Communities is a uniquely comprehensive reference covering pollution in coastal marine and estuarine waters. The book provides a detailed look at the short- and long-term impacts of pollutants on these ecologically important regions. Case studies that reflect a broad range of pollution problems are analyzed, outlining the real-life issues and providing solutions to common problems. Despite being highly sensitive systems, estuarine and coastal marine environments have served as repositories for dredge spoils, sewage sludge, and industrial and municipal effluents for many decades. The adverse effects of these pollutants are only now being fully realized and understood. Pollution Impacts on Marine Biotic Communities includes a basic introduction to the subject of pollution in estuarine and marine environments and also a detailed examination of specific marine pollutants. Both the coverage and the format - which includes abundant illustrations and tables - make this book a valuable reference for scientists, administrators, and students engaged in coastal research and planning.

This research level text focuses on the influence of climate variability on the marine ecosystems of the North Atlantic. The ecological impact of climate variability on population dynamics is addressed at the full range of trophic levels, from phytoplankton through zooplankton and fish to marine birds. Climate effects on biodiversity and community structure are also examined. 40 scientists from around the world synthesise what is currently known about how climate affects the ecological systems of the North Atlantic and then place these insights within a broader ecological perspective. Many of the general features of the North Atlantic region are also seen in other marine ecosystems as well as terrestrial and freshwater systems. The final section of the book makes these generalities more explicit, so as to stimulate communication and promote co-operation amongst researchers who may previously have worked in semi-isolation. The book comprises 5 main sections: background (general introduction, atmospheric and ocean climate of the North Atlantic, and modelling methodology), plankton populations (phytoplankton and zooplankton), fish and seabird populations, community ecology (phytoplankton, benthos and fish), and the final section consisting of six commentaries from scientists working in areas outside the North Atlantic marine sector. In order to enhance integration, a series of introductions link chapters and sections. Throughout the book, numerous examples highlight different aspects of ecology-climate interactions. They document recent progress and illustrate the challenges of trying to understand ecological processes and patterns in the light of climate variations.

Marine sediments dominate the global seabed, creating the largest ecosystem on earth. Seafloor biodiversity is a key mediator of ecosystem functioning, yet critical processes are often excluded from global biogeochemical budgets or simplified to black boxes in ecosystem models. This accessible textbook provides an ideal point of entry into the field, providing basic information on the nature of soft-sediment ecosystems, examples of how and why we research them, the new questions these studies inspire, and the applications that ultimately benefit society. While focussing on coastal habitats (

Marine management requires approaches which bring together the best research from the natural and social sciences. It requires stakeholders to be well-informed by science and to work across administrative and geographical boundaries, a feature especially important in the inter-connected marine environment. Marine management must ensure that the natural structure and functioning of ecosystems is maintained to provide ecosystem services. Once those marine ecosystem services have been created, they deliver societal goods as long as society inputs its skills, time, money and energy to gather those benefits. However, if societal goods and benefits are to be limitless, society requires appropriate administrative, legal and management mechanisms to ensure that the use of such benefits do not impact on environmental quality, but instead support its sustainable use.
