Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Book excerpt: Seventeen-year-old Addisyn Parker is used to being different. From an early age, she's had the ability to see otherworldly creatures with shimmering skin and glowing irises that are completely imaginary to everyone else. Her sporadic hallucinations continually haunt her to no end. Addisyn's life takes an unexpected turn when an absurdly handsome stranger, Drake Carpathia, reveals a sudden interest in her. Despite her best efforts in evading him, Drake's unwavering advances are not something that can be ignored. There's something different about him-an entrancing secret that Addisyn finds hard to resist. Unexplainable events start to unfold as Drake submerges her into a world full of possibilities that Addisyn thought only existed in myths and legends. Strange, paranormal events start happening around her, including frequent visits from one of the ethereal beings who seems hell-bent on stalking her. With all of the supernatural chaos, Addisyn literally has no option but to believe the impossible or risk living a life shrouded by insanity.

Available in PDF, EPUB and Kindle. Book excerpt: "The book before you...carries the urgent warning that we are rapidly altering and destroying the environments that have fostered the diversity of life forms for more than a billion years." With those words, Edward O. Wilson opened the landmark volume Biodiversity (National Academy Press, 1988). Despite this and other such alarms, species continue to vanish at a rapid rate, taking with them their genetic legacy and potential benefits. Many disappear before they can even be identified. Biodiversity II is a renewed call for urgency. This volume updates readers on how much we already know and how much remains to be identified scientifically. It explores new strategies for quantifying, understanding, and protecting biodiversity, including: New approaches to the integration of electronic data, including a proposal for a U.S. National Biodiversity Information Center. Application of techniques developed in the human genome project to species identification and classification. The Gap Analysis Program of the National Biological Survey, which uses layered satellite, climatic, and biological data to assess distribution and better manage biodiversity. The significant contribution of museum collections to identifying and categorizing species, which is essential for understanding ecological function and for targeting organisms and regions at risk. The book describes our growing understanding of how megacenters of diversity (e.g., rainforest insects, coral reefs) are formed, maintained, and lost; what can be learned from mounting bird extinctions; and how conservation efforts for neotropical primates have fared. It also explores ecosystem restoration, sustainable development, and agricultural impact. Biodiversity II reinforces the idea that the conservation of our biological resources is within reach as long as we pool resources; better coordinate the efforts of existing institutionsâ€"museums, universities, and government agenciesâ€"already dedicated to this goal; and enhance support for research, collections, and training. This volume will be important to environmentalists, biologists, ecologists, educators, students, and concerned individuals.

Book excerpt: Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.

This book was released on 2021-07-02 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document elaborates the revised International Standard Statistical Classification of Fishing Gear (ISSCFG), as endorsed and adopted for implementation by the FAO Coordinating Working Party on Fishery Statistics (CWP) at its Twenty-fifth Session in February 2016 in Rome, Italy. The classification applies to commercial, subsistence and recreational fisheries in marine and freshwater fisheries. The document provides definitions and illustrations of the configuration and mode of operation of typical fishing gears. The primary purpose is to assist FAO Members, regional fishery bodies, as well as those working on fishery statistics and management, to correctly attribute and report fisheries catches made by different gear types. The document also contributes to the prevention, deterrence and elimination of illegal, unreported and unregulated (IUU) fishing by providing monitoring, control and surveillance personnel with information to identify the type of fishing gear with regard to licence and authorization to carry out fishing operations. Finally, the document also provides context and references for some contemporary conservation issues related to major fishing gear types; it can therefore be used as a reference text for students and researchers in fisheries and marine conservation.

Available in PDF, EPUB and Kindle. Book excerpt: There are many things and services in our everyday life that we take for granted, and telecommunications is one of them. We surf the internet, send emails to friends and colleagues abroad, talk to family members in foreign countries over the phone, book airline seats and make banking transactions without actually realizing and appreciating the sophisticated technology that enables us to do so. This report covers the history and nature of cables, their special status in international law, their interaction with the environment and other ocean users and, finally, the challenges of the future. It is an evidence-based synopsis that aims to improve the quality and availability of information to enhance understanding and cooperation between all stakeholders. UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared this new report to provide an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use.

Available in PDF, EPUB and Kindle. Book excerpt: Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.

Book excerpt: Seamounts are ubiquitous undersea mountains rising from the ocean seafloor that do not reach the surface. There are likely many hundreds of thousands of seamounts, they are usually formed from volcanoes in the deep sea and are defined by oceanographers as independent features that rise to at least 0.5 km above the seafloor, although smaller features may have the same origin. This book follows a logical progression from geological and physical processes, ecology, biology and biogeography, to exploitation, management and conservation concerns. In 21 Chapters written by 57 of the world’s leading seamount experts, the book reviews all aspects of their geology, ecology, biology, exploitation, conservation and management. In Section I of this book, several detection and estimation techniques for tallying seamounts are reviewed, along with a history of seamount research. This book represents a unique and fresh synthesis of knowledge of seamounts and their biota and is an essential reference work on the topic. It is an essential purchase for all fisheries scientists and managers, fish biologists, marine biologists and ecologists, environmental scientists, conservation biologists and oceanographers. It will also be of interest to members of fish and wildlife agencies and government departments covering conservation and management. Supplementary material is available at: www.seamountsbook.info

This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch is the unwanted or non-target part of the catch taken by fishermen. It is either discarded at sea or used for human or animal consumption. The capture of bycatch may pose a threat to species diversity and ecosystem health because this part of the catch is usually unregulated. In tropical shrimp-trawl fisheries, bycatch often consists of juvenile food-fish species and is therefore a threat to food security and sustainable fisheries production. Bycatch is a global problem that must be addressed. This Guide to Bycatch Reduction in Tropical Shrimp-Trawl Fisheries is designed for fishermen, net makers, fishing technologists and others interested in a practical guide to the design, use and operation of effective bycatch reduction devices. Fishery managers, policy-makers and legislators will find this guide useful to help develop specifications governing the design and application of these devices in a shrimptrawl fishery. The issue of bycatch is not going away and scrutiny of fishing activity is increasing. All fishermen are strongly urged to use appropriate bycatch reduction measures to help maintain the productivity of the fishery and the long term prosperity of the fishing industry. By responding appropriately, fishermen can help to protect the marine environment and assist global food security both now and in the future. Also published in French and Spanish.
