Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Worldwide review of bottom fisheries in the high seas in 2016 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-02-28 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Worldwide review of bottom fisheries in the high seas in 2016 is an update to the first Worldwide review of bottom fisheries in the high seas, published in 2009 based on information from 2003 to 2006. It provides states and other interested parties with a summary of the current status of high seas bottom fisheries worldwide. The present, updated review begins with a description of the demersal finfish and shellfish resources, before offering a global perspective on fisheries and management; it then provides specific, regional information over eleven chapters covering the high seas of the world’s oceans, by region. Drawing on data up to and including 2016, it provides a survey of the current state of bottom fisheries since the original Worldwide review, considering these fisheries in the context of their historical evolution.
Download or read book Fundamentals of Tree Ring Research written by James H. Speer and published by University of Arizona Press. This book was released on 2021-11-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.
Download or read book Handbook of Fish Biology and Fisheries written by Paul J. B. Hart and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed strong declines in fish stocks aroundthe globe, amid growing concerns about the impact of fisheries onmarine and freshwater biodiversity. Fisheries biologists andmanagers are therefore increasingly asking about aspects ofecology, behaviour, evolution and biodiversity that weretraditionally studied by people working in very separate fields.This has highlighted the need to work more closely together, inorder to help ensure future success both in management andconservation. The Handbook of Fish Biology and Fisheries has beenwritten by an international team of scientists and practitioners,to provide an overview of the biology of freshwater and marine fishspecies together with the science that supports fisheriesmanagement and conservation. This volume, subtitled Fish Biology, reviews a broadvariety of topics from evolutionary relationships and globalbiogeography to physiology, recruitment, life histories, genetics,foraging behaviour, reproductive behaviour and community ecology.The second volume, subtitled Fisheries, uses much of thisinformation in a wide-ranging review of fisheries biology,including methods of capture, marketing, economics, stockassessment, forecasting, ecosystem impacts and conservation. Together, these books present the state of the art in ourunderstanding of fish biology and fisheries and will serve asvaluable references for undergraduates and graduates looking for acomprehensive source on a wide variety of topics in fisheriesscience. They will also be useful to researchers who needup-to-date reviews of topics that impinge on their fields, anddecision makers who need to appreciate the scientific backgroundfor management and conservation of aquatic ecosystems.

Download or read book Discards in the World s Marine Fisheries written by Kieran Kelleher and published by Food & Agriculture Org.. This book was released on 2005 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.
Download or read book Review of the State of World Marine Fishery Resources written by Food and Agriculture Organization of the United Nations. Marine Resources Service and published by Food & Agriculture Org.. This book was released on 1994 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.
Download or read book Natural Resources Sustainability and Humanity written by Angela Mendonca and published by Springer Science & Business Media. This book was released on 2012-04-17 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shortly, this book is the written up-graded version of the topics discussed during the Small Meeting of the 2nd International School Congress: Natural Resources, Sustainability and Humanity, held in Braga, Portugal, 5-8 May 2010 with the diverse participation of scientists, educators and governmental representatives. The Earth hosts an immense ecosystem, colonized by millions of species for billions of years but only for a few tens of thousands of years by humans. Environmental history tells though that it was humankind that shaped the environment as no other species. History, geography, religion and politics among other reasons have differentiated populations with respect to access to safe food and water, education, health, and to space and natural resource utilization. The globalization era of trade, information and communication is shortening distances and increasing overall wealth, but, as is pointed out in this book, it is also contributing to the propagation of diseases, and to the modification or even destruction of native ecosystems by exotic invasive species. Man is the only species that has the perception of its history, evolution, of the consequences of its decisions, and that there is a future ahead. It is also the only species that has the potential to change it. This awareness can be a source of anxiety and contradictory behaviours, but it is also the key to changing attitudes towards the construction of a common sustainable home, by committed education, interdisciplinary approaches, mobilization and empowerment of people and political consonant actions.
Download or read book Slow Violence and the Environmentalism of the Poor written by Rob Nixon and published by Harvard University Press. This book was released on 2011-06-01 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: The violence wrought by climate change, toxic drift, deforestation, oil spills, and the environmental aftermath of war takes place gradually and often invisibly. Using the innovative concept of "slow violence" to describe these threats, Rob Nixon focuses on the inattention we have paid to the attritional lethality of many environmental crises, in contrast with the sensational, spectacle-driven messaging that impels public activism today. Slow violence, because it is so readily ignored by a hard-charging capitalism, exacerbates the vulnerability of ecosystems and of people who are poor, disempowered, and often involuntarily displaced, while fueling social conflicts that arise from desperation as life-sustaining conditions erode. In a book of extraordinary scope, Nixon examines a cluster of writer-activists affiliated with the environmentalism of the poor in the global South. By approaching environmental justice literature from this transnational perspective, he exposes the limitations of the national and local frames that dominate environmental writing. And by skillfully illuminating the strategies these writer-activists deploy to give dramatic visibility to environmental emergencies, Nixon invites his readers to engage with some of the most pressing challenges of our time.

Download or read book Haunted written by Chuck Palahniuk and published by Anchor. This book was released on 2005-05-03 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Haunted is a novel made up of twenty-three horrifying, hilarious, and stomach-churning stories. They’re told by people who have answered an ad for a writer’s retreat and unwittingly joined a “Survivor”-like scenario where the host withholds heat, power, and food. As the storytellers grow more desperate, their tales become more extreme, and they ruthlessly plot to make themselves the hero of the reality show that will surely be made from their plight. This is one of the most disturbing and outrageous books you’ll ever read, one that could only come from the mind of Chuck Palahniuk.
Download or read book Conserving the Oceans written by Justin Alger and published by Oxford University Press. This book was released on 2021 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Conserving the Oceans: The Politics of Large Marine Protected Areas documents the efforts of activists and states to increase the pace and scale of global ocean protections, leading to a new global norm in ocean conservation of large marine protected areas exceeding 200,000 km2. Through an analysis of domestic political economies, the book explains how states have protected millions of square kilometers of ocean space while remaining highly responsive to the interests of businesses. It argues that states design environmental policies above all around two key features of a given space: (1) the composition of extractive versus non-extractive industry interests; and (2) the salience of various industry interests, defined as the degree to which businesses would suffer tangible and significant costs in response to new environmental regulations. Through an analysis of large marine protected area advocacy campaigns in Australia, Palau, and the United States, this book demonstrates how the political economy of a given marine space shapes how governments align their environmental and economic goals, sometimes strengthening conservation but more often than not undermining it. While recognizing important global progress and growing ambition to conserve ocean ecosystems, Conserving the Oceans demonstrates that even ambitious large marine protected areas have so far not fundamentally challenged a neoliberal paradigm of environmentalism that has caused considerable ecological harm"--
Download or read book Free Market Environmentalism written by T. Anderson and published by Springer. This book was released on 2001-02-02 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original edition of this seminal book, published in 1991, introduced the concept of using markets and property rights to protect and improve environmental quality. Since publication, the ideas in this book have been adopted not only by conservative circles but by a wide range of environmental groups. To mention a few examples, Defenders of Wildlife applies the tenets of free market environmentalism to its wolf compensation program; World Wildlife Federation has successfully launched the CAMPFIRE program in southern Africa to reward native villagers who conserve elephants; and the Oregon Water Trust uses water markets to purchase or lease water for salmon and steelhead habitats. This revised edition updates the successful applications of free market environmentalism and adds two new chapters.
