This introduction to basic concepts of biodiversity-sampling outlines standardized field methods for macroalgae and seagrass communities developed by NaGISA (Natural Geography in Shore Areas), a project operating under the international Census of Marine Life. NaGISA promotes simple standardized protocols and focuses on widespread nearshore habitats. This book, written by premier coastal ecologists and taxonomists, provides a text for field courses, a manual for coastal managers, and a reference guide for researchers studying biodiversity or preparing species inventories.
Those of us who live in California know that it is an amazing place, and one of the reasons our state is so unique is the incredible diversity of life throughout its length and breadth. This atlas shows what the diversity of life in California is and where such resources are located.
Reflecting the increasing interest in the field and its relevance in global environmental issues, Oceanography and Marine Biology: An Annual Review provides authoritative reviews that summarize results of recent research in basic areas of marine research, exploring topics of special and topical importance while adding to new areas as they arise. This volume, part of a series that regards the all marine sciences as a complete unit, features contributions from experts involved in biological, chemical, geological, and physical aspects of marine science. Including a full color insert and an extensive reference list, the text is an essential reference for researchers and students in all fields of marine science.
The diversity of marine life is being affected dramatically by fishery operations, chemical pollution and eutrophication, alteration of physical habitat, exotic species invasion, and effects of other human activities. Effective solutions will require an expanded understanding of the patterns and processes that control the diversity of life in the sea. Understanding Marine Biodiversity outlines the current state of our knowledge, and propose research agenda on marine biological diversity. This agenda represents a fundamental change in studying the oceanâ€"emphasizing regional research across a range of space and time scales, enhancing the interface between taxonomy and ecology, and linking oceanographic and ecological approaches. Highlighted with examples and brief case studies, this volume illustrates the depth and breadth of undescribed marine biodiversity, explores critical environmental issues, advocates the use of regionally defined model systems, and identifies a series of key biodiversity research questions. The authors examine the utility of various research approachesâ€"theory and modeling, retrospective analysis, integration of biotic and oceanographic surveysâ€"and review recent advances in molecular genetics, instrumentation, and sampling techniques applicable to the research agenda. Throughout the book the critical role of taxonomy is emphasized. Informative to the scientist and accessible to the policymaker, Understanding Marine Biodiversity will be of specific interest to marine biologists, ecologists, oceanographers, and research administrators, and to government agencies responsible for utilizing, managing, and protecting the oceans.
Large amounts of pollutants and natural disasters have been released into coastal and marine waters, wreaking havoc on the ecosystem and ecology. Pollution and habitat loss caused by humans have had and continue to have a significant impact on worldwide coastal and estuarine ecosystems. More than 80% of all marine pollution originates on land, with the majority of it coming from industrial, agricultural, and urban sources. Coastal and marine pollution is caused by human activities such as offshore oil and gas extraction and maritime oil transportation. Many of the world's estuaries and coastal zones are experiencing eutrophication, hypoxia, and other negative consequences as a result of anthropogenic activities. As a result, it's vital to avoid and regulate coastal and marine pollution, as well as build improved monitoring protocols and systems to aid in the understanding of spatial and temporal changes in coastal water quality. Recent technological advancements in coastal and marine seawater quality monitoring, such as real-time data collecting via data buoys, large-scale remote sensing intervention, automated data collection, and so on, are critical for comprehending real-time data and its influence on the environment.
Ecosystems of the benthic environment are a sensitive index toecological change, and as such demand long-term and effectivemonitoring. Methods for the Study of Marine Benthos providescomprehensive information on the tools and techniques available tothose working in areas where the declining health of the sea,depletion of marine resources and the biodiversity of marine lifeare major concerns. In response to the need for increasingly detailed information onbottom-living communities, this fully revised new editionoffers: Contributions from a broad range of internationally recognisedexperts New information for those compiling environmental impactstatements, pollution assessments and working with eco-systemmanagement Two separate chapters on Imaging Techniques and DivingSystems A vital tool for all marine and environmental scientists,ecologists, fisheries workers and oceanographers, libraries in alluniversities and research establishments where these subjects arestudied and taught will find this book a valuable addition to theirshelves.
This accessible and timely book provides a comprehensive overview of how to measure biodiversity. The book highlights new developments, including innovative approaches to measuring taxonomic distinctness and estimating species richness, and evaluates these alongside traditional methods such as species abundance distributions, and diversity and evenness statistics. Helps the reader quantify and interpret patterns of ecological diversity, focusing on the measurement and estimation of species richness and abundance. Explores the concept of ecological diversity, bringing new perspectives to a field beset by contradictory views and advice. Discussion spans issues such as the meaning of community in the context of ecological diversity, scales of diversity and distribution of diversity among taxa Highlights advances in measurement paying particular attention to new techniques such as species richness estimation, application of measures of diversity to conservation and environmental management and addressing sampling issues Includes worked examples of key methods in helping people to understand the techniques and use available computer packages more effectively
This is a detailed assessment of the state of biodiversity in the Atlantic Forest. Separate sections examine each of the three countries that are home to the forest, beginning with a brief overview that explores the dynamics of biodiversity loss in that country and outlining the topics to be addressed.
