Book excerpt: This textbook presents a comprehensive overview of the environmental impacts of various types of adventure tourism and how these can be best managed. This volume follows on from the authors previous textbook – ‘Outdoor Recreation: Environmental Impacts and Management’ and continues the aim of developing a deeper understanding of how tourist numbers impact the environment and to provide practical solutions to these problems. Combining their own first-hand experience and research with extensive literature review the authors' present several popular adventure tourism destinations from across the globe, including the Arctic, the Himalayas, Africa, Australia and Scotland as case studies. Chapters cover the particular challenges faced by each region: including impacts on animals and birds; the spread of invasive plant species and diseases; trail impacts on vegetation; impacts on geological, historical and archaeological sites and pollution and waste issues. A discussion and evaluation of the possible management actions for minimising these impacts and how outdoor recreation tourists can be regulated concludes each chapter. This practical and engaging textbook will be invaluable to students and scholars of adventure tourism and outdoor recreation as well as practitioners and managers working in the field.

Download or read book Handbook of Chemical Risk Assessment written by Ronald Eisler and published by CRC Press. This book was released on 2000-04-12 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written over a period of 17 years, the Handbook of Chemical Risk Assessment exhaustively examines and analyzes the world literature on chemicals entering the environment from human activities. The three volumes cover chemicals recommended by environmental specialists of the U.S. Fish and Wildlife Service and other resource managers. The choices were based on the real or potential impact of each contaminant and on the knowledge available about their mitigation. The information for each chemical includes source and use; physical, chemical, and metabolic properties; concentrations in field collections of abiotic materials and living organisms; deficiency effects; lethal and sublethal effects; and proposed regulatory criteria for the protection of human health and sensitive natural resources. Each chapter selectively reviews and synthesizes the technical literature on a specific priority contaminant and its effects on the environment. Successful risk assessment relies heavily on extensive and well-documented databases. They often include too much - or too little - information about too many chemicals. Of the hundreds of thousands of chemicals discharged into the environment, only a small number have sufficient information to attempt preliminary risk assessment. Sold only as a three volume set, the Handbook of Chemical Risk Assessment provides you with the exact amount of information you need in a single resource.
Download or read book Algal Toxins Nature Occurrence Effect and Detection written by Valtere Evangelista and published by Springer Science & Business Media. This book was released on 2008-06-27 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures and seminars given at the NATO Advanced Study Institute on “Sensor Systems for Biological Threads: The Algal Toxins Case”, held in Pisa, Italy in October, 2007. The Institute was sponsored and funded by the Scientific Affairs Division of NATO. It is my pleasant duty to thank this institution. This ASI offered updated information on how far the research on algal toxins has gone in the exploration of structures, biosynthesis and regulation of toxins, and the development of technology for bio-monitoring these c- pounds. Algae can form heavy growths in ponds, lakes, reservoirs and sl- moving rivers throughout the world; algae can house toxins which are - ually released into water when the cells rupture or die. Hundreds of toxins have been identified so far. Detection methods, including rapid screening, have been developed to help us learning more about them, especially to find out which toxins are a real threat for people and what conditions encourage their production and accumulation. Early detection of algal toxins is an - portant aspect for public safety and natural environment, and significant efforts are underway to develop effective and reliable tools that can be used for this purpose.
Download or read book Salmon written by P. T. K. Woo and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a good mix of both basic and applied topics in the hope that it will be useful and of interest to scientists working on finfish. It has 15 chapters written by 27 contributors and many of them are highly respected scientists. Given the global importance of salmon, contributors are from many countries including 11 from Japan and Russia. These authors bring slightly different and important perspectives to the book, and their expertise and research may not be known to many young scientists in Europe and in the Americas. The volume starts with an overview of salmon, their economic and social importance, and their impacts on the environment. Subsequent topics include morphological, physiological and behavioural differences between wild and farmed salmon; growth, food utilisation and water flow requirements of wild and hatchery salmon; the real and potential ecological impacts of sea cages and hatcheries; the potential use of waste product (gelatine) from the salmon industry; salmon behaviour and genetics including their broad applications that contribute to our understanding of fish biology, and nutritional and anti-nutritional factors in salmon culture. There are also chapters on environmental impacts and the economic importance of the commercial fishery and salmon farming industry; these are very important components of the industry, especially to the seafood sector.
Download or read book The Economics of Salmon Aquaculture written by Frank Asche and published by John Wiley & Sons. This book was released on 2011-05-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1990, The Economics of Salmon Aquaculture was the first book to systematically analyse the salmon aquaculture industry, from both a market and production perspective. Since publication of the first edition of this book, the salmon aquaculture industry has grown at a phenomenal rate, with salmon now being consumed in more than 100 countries worldwide. This second edition of a very popular and successful book brings the reader right up to date with all the major current issues pertaining to salmon aquaculture. Commencing with an overview of the production process in aquaculture, the following chapters provide in-depth coverage of the sources of the world’s supply of salmon, the growth in productivity, technological changes, environmental issues, markets, market structure and competitiveness, lessons that can be learnt from the culture of other species, optimal harvesting techniques, production planning, and investment in salmon farms. Written by Frank Ashe and Trond Bjørndal, two of the world's leading experts in the economics of aquaculture, this second edition of The Economics of Salmon Aquaculture provides the salmon aquaculture industry with an essential reference work, including a wealth of commercially important information. This book is also a valuable resource for upper level students and professionals in aquaculture and economics, and libraries in all universities and research establishments where these subjects are studied and taught should have copies of this important book on their shelves.

Available in PDF, EPUB and Kindle. Book excerpt: This beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri. North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon. How this came to be, how they are related, and what makes them unique -- and so breathtaking -- is the story of Trout and Salmon of North America. The more than 100 illustrations of trout and salmon by Joseph Tomelleri showcased here exhibit a genius for detail, coloration, and proportion. Each portrait is made from field notes, streamside observations, photographs, and specimens collected by the artist. The result is a set of the most accurate and stunning illustrations of fish ever created. Robert Behnke has distilled 50 years of his research and writing about trout and salmon in completing this book. No one understands better than Behnke the diversity and conservation issues concerning these fishes or communicates so lucidly the biological wonders and complexities of their particular beauty. Also included are more than 40 richly detailed maps that clearly show the ranges of populations of trout and salmon throughout North America. An irresistible delight for anyone who appreciates natural history, Trout and Salmon of North America is a master guide to the natural elegance of our native fishes.
Download or read book A Wild Promise written by Debbie S. Miller and published by Mountaineers Books. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2018 Foreword INDIES Book of the Year Awards Finalist in Nature The 2.1 million acres (equivalent to Yellowstone National Park) of the wilderness study area are coming under increasing threat by resource development Essays of personal explorations of the region by an award-winning writer are accompanied by dramatic images from an award-winning photographer The wilderness study area is home to the largest concentration of tidewater glaciers in America and hosts a vast diversity of terrestrial and aquatic mammals, birds, and fish It's been said that "a picture is worth a thousand words," and nowhere is that more true than on the pages ofA Wild Promise: Prince William Sound. The images of photographer Hugh Rose show you what this region holds--and what will be lost without protection from future resource development. Alongside Hugh's images are eloquent essays covering the natural and cultural history, people, and fragility of this region by noted Alaskan writer Debbie Miller. Alaska's famed Prince William Sound includes more than 3,000 shore land miles of bays, coves, and deep fjords topped by the ice-capped peaks of the Chugach Mountains. More than 1 million tourists visit the region annually, and small family-owned fishing boats, ecotourism, oyster farms, and guide services provide sustainable livelihoods for year-round Alaskan residents. Many Americans first came to know of Prince William Sound through the Exxon Valdez oil spill of 1989--a catastrophe with lingering long-term effects, such the collapse of the once abundant herring population, a critical fish in the marine food chain. InA Wild Promise, readers travel alongside Hugh and Debbie as they hike and kayak from Columbia Glacier to College Fiord, exploring the Nellie Juan-College Fjord Wilderness Study Area, a region set aside for study in 1980, to be followed--it was hoped--by permanent protection from Congress. After almost four decades of being in limbo as a designated wilderness study area, the fate of this spectacular, wild place is now in our hands. Its protection is a gift we can offer generations to come--a promiseof wilderness, beauty, and natural diversity that we can, indeed, keep.
Download or read book Dear Chairwoman written by Syvliane Grant and published by . This book was released on 2021-04-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: DEDICATED TO THE NEXT GENERATION OF WOMEN BOARD LEADERSIn 2018, California passed a senate bill (SB 826) to require publicly held companies headquartered in CA to have at least one woman on their board by 2020. In 2020, Nasdaq proposed a mandate that would require listed companies to have at least two diverse board members with one member who identifies as female. Initiatives like these are helping advance gender parity on boards in many regions, not just the U.S. In late 2020, women held 22.6% of the board seats on the Russell 3000 for the first time, a 6.5 point jump over the past 4 years.Zooming out to the global scale, the picture is similarly improving. In 2020, about 23% of board seats globally were held by women, compared to 20% in 2018. Yet...at the time of this writing, 10% of large global companies do not have a single woman on their board. And the percent of women who chair boards is dramatically smaller. Among the largest 500 public U.S. companies by revenue the share of women who chaired boards remained stagnant at 7.4%. Notably, of those women who chair boards, few of them use the term Chairwoman in their bios or LinkedIn profiles-opting for monikers Chairman, or Board Chair, or occasionally Chairperson. This book features the extraordinary voices and stories of women leaders from around the world who have trailblazed to the board room, as letters to the next generation of women in business and government. With the salutation "Dear Chairwoman," these letters are infused with the energy to inspire young women to both pursue board governance early, and to claim the 'Chairwoman' title in taking the senior-most seat in the Board Room.
