Book Description
This book is an unpretentious editing venture to fill the gap in our current knowledge on the ecological implications caused by anthropogenic disturbances upon benthic communities in several regions of the world, including the Western Atlantic, the Mediterranean Sea, and the Eastern Pacific Ocean, as well as the pristine environments of the Andes in South America. The common goal of the contributing authors in this book was to unravel the complex processes that make possible the life existence of bottom-living animals in different environmental scenarios. To achieve such a goal, the authors focus their attention on the emerging issues inherent to global climate change or the pollution of aquatic systems. These are all themes that might be of interest to scientists active in a wide range of oceanographic subdisciplines. Well-established researchers would appreciate the innovative approach adopted in each chapter of the book, which extends from the ecosystem level to refined molecular interpretations.

Book Description
Due to its particular characteristics, the Mediterranean Sea is often viewed as a microcosm of the World Ocean. Its proportionally-reduced dimensions and peculiar hydrological circulation render it susceptible to environmental and climatic constraints, which are rapidly evolving. The Mediterranean is therefore an ideal site to examine, in order to better understand a number of key oceanographic phenomena. This is especially true of the Ligurian Sea where, due to its geology, oceanic conditions are found close to the coast. As such, 30 years ago, an offshore time-series site provided a fresh impetus to a long history of marine biology research, which has generated a very important body of data and knowledge. This is the second volume, in a two-volume series, that summarizes this research. Across these two books, the reader will find 13 chapters that examine the geology, physics, chemistry and biology of the Ligurian Sea ? always with the goal of providing key elements of oceanography in a changing world.

Book Description
Marine ecosystems are threatened by CO2-driven global change, such as ocean warming and acidification (OA). The primary objectives of this study were to: 1) assess the response of the coralline red alga, Calliarthron cheilosporioides, to global change; and 2) investigate the responses of California’s kelp forest communities to OA and sea urchin grazing. Results indicated that C. cheilosporioides growth and calcification were reduced under both increased temperatures and increased pCO2 despite increased photosynthetic rates in high pCO2 conditions. Mineralogy did not differ among treatments as a function of warming or acidification. Differences were observed in Mg incorporation into calcified walls of different cell types. Impacts of OA and sea urchin grazing on community structure differed in central and southern CA. In central CA, community structure, calcification and juvenile kelp density showed strong effects of grazing, but no effect of pCO2. Conversely, southern CA showed minor effects of grazing, but strong effects of pCO2 on community structure and calcification, with the strength of response depending on the initial assemblage. These findings suggest that some species of coralline algae may be negatively affected by increased pCO2 and temperature and that the emergent effects of ocean acidification may differ both within a reef as well as across broad spatial scales.

Book Description
This book provides effective statistical analyses in benthic foraminiferal communities patterns and show solutions for sea-land processes and alterations caused by climate changes and other local (and global) environmental concerns. Our goal is to provide, through these chapters, the monitoring and forecasting of environmental impacts with accurate data. We identify global regions most subject to industrial pollution, contamination and sewage, identifying potential sites prone to accumulate organic matter, which effects erosion, deposition, ocean temperature and pH changes (warming, cooling, acidification), climate and sea-level changes. Benthic habitats, specifically foraminiferal (single celled microorganisms found in the water column and sediment) contribute to our understanding of local and global climate change that effect at risk communities. Derived through the accuracy of oceanographic climate science, allow us to predict with the intention to alleviate potential loss in coastal areas, which are, the most vulnerable to ocean warming, cooling, acidification, and sea-level rise impacts. We unravel the mystery of the Environmental Impacts and Climate Change, helping communities prepare, adjust, adapt, and minimize effects or remediate loss. We show how to pinpoint the most vulnerable and specific sites for economic and social damage and loss, using foraminifera, an inexpensive and easily handled proxy valuable for monitoring coastal and marine environmental stressors. The implications of those problems and the ability to forecast patterns on land are primary issues we address by studying marine sediment of beaches, estuaries, bays and deep water worldwide. Ecology, biology, life history, and taxonomy of modern Foraminifera allows us to examine the current and historical record of environmental change effects, and predict implications for future sea-level rise, and ocean patterns. The prediction of responses of interacting systems to these problems, and development of strategies is needed to inform leadership with the knowledge and data to effectively implement policy, making this book a very informative and significant contribution for researchers and decision makers.

Book Description
This volume is an indispensable addition to the multidisciplinary coverage of the science of the Mediterranean Sea. The editors have gathered leading authorities from the fields of Marine Biology, Ecology, paleoclimatology, Chemical and Physical Oceanography, Zoology, Botany, Aquatic Photosynthesis, Socioeconomics, Mariculture, Mediterranean History and Science of Humanity. Beginning with the birth of the Mediterranean Sea and its myths. From coral to fish, an introduction is given to its major inhabitants of plants and animals past and present. The chapters illustrate how organisms interact as part of the structure and function of the Sea's main ecosystems. The rise of the Mediterranean as the cradle of the Western Civilization leads to a discourse on the status of human interaction with the sea. Accelerating global climate change, water warming, ocean acidification and sea level rise, and analyses of their effects on key organisms, entire ecosystems and human socioeconomics are given. Forecasting and predictions are presented taking into account different future scenarios from the IPCC (International Panel on Climate Change). The volume is richly illustrated in color, with an extensive bibliography. A valuable addition to the limited literature in the field, offering up-to-date broad coverage merging science and humanities.​

Book Description
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.
