This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

Much of the country's recent population growth is situated in exurban areas. By many accounts exurbanization has become the dominant pattern of land development in the country and there is no indication it will slow in the foreseeable future (Theobald 2005; Brown et al. 2005; Glennon and Kretser 2005). By definition, exurban development takes place beyond the metropolitan fringe, often in rural and remote areas. The development of new exurban communities is a growing trend, especially in the West. In this case, developers and homebuilders seek large tracts of land, up to thousands of acres, in rural areas (typically within 50 miles of a large city) where they plan entire communities consisting of commercial, retail and residential land uses. Recreational amenities such as golf courses and hiking/biking trails are often included in these master-planned developments. Our philosophy is reflected in the book's two objectives. First, we seek to document the extent and impacts of exurban development across the country. At issue is demonstrating why planners and the public-at-large should be concerned about exurbanization. We will demonstrate that even though exurbanization favors amenity rich regions, it affects all areas of the country through the loss of agricultural and grazing lands, impacts to watersheds and land modification. A summary of environmental impacts is presented, including the loss of wildlands and agricultural productivity, land modification, soil erosion, impacts to terrestrial hydrologic systems, the loss of biodiversity, nonnative and endangered species and other topics. Our second aim is to provide readers from diverse (nonscientific) backgrounds with a working knowledge of how and why exurbanization impacts environmental systems. This is accomplished by working closely to ensure contributors follow a specific outline for each chapter. First, contributors will spell out fundamental concepts, principles and processes that apply to their area of expertise (e.g., riparian areas). Contributors will move beyond a cursory understanding of ecological processes without overwhelming readers with the dense material found typically in specialized texts. For this reason, visuals and other support materials will be integral to each chapter. We have chosen contributors carefully based on their record as research scientists and acumen as educators. Second, once the mechanics have been laid out, authors will explain how and why land development in nearby areas influences ecosystems. Issues of interdependency, modification and adaptation, spatial scale and varying time horizons will be featured. Third, contributors will weigh in on the pros and cons of various land-development schemes. Fourth, authors will share their thinking on the merits of conservation devices such as wildlife corridors, open-space requirements and watershed management districts. Finally, each chapter will conclude by identifying pitfalls to avoid and highlighting "best practices" that will mitigate environmental problems or avoid them altogether. In sum, after completing each chapter, readers should have a firm grasp of relevant concepts and processes, an understanding of current research and know how to apply science to land-use decisions.
The book, a study of policymaking for conservation in Latin America, employs comparative analysis to explain the policy process in three countries—Argentina, Chile, and Costa Rica. Case studies and examples of important policy decisions made in the three countries are employed to help illuminate variations in the policy process from country to country. The analysis is set against the constant conflict between demands for economic development and conservation. Hopkins has selected important examples of policy problems in the areas of conservation, national parks, and environmental protection in the three countries and set these against the political system in each country for comparison. The cases range from the controversial issue of Lago Chungara in Chile to Corcovado National Park in Costa Rica to the Yacyreta hydroelectric project in Argentina. The study aims at beginning to fill an important gap in the literature on national parks, conservation, and environmental protection in Latin America. As such, the volume will be of interest to students of contemporary Latin America, policymaking, and environmental studies.
As climate change continues to threaten both our economic and ecological well-being, countries around the world are trying to implement green strategies that will simultaneously curb emissions and spur economic growth. Green Japan critically examines the Japanese effort to combine economic growth with commitments to environmental sustainability. Carin Holroyd explores green growth strategies in various industries including conservation, energy, urban development, and international trade. Holroyd's comprehensive analysis of how innovation strategies connect with environmental priorities combines a detailed study of government policies with insightful assessments of consumer and market responses. The unevenness of Japan's success clearly demonstrates the exceptional technological innovation and creative public policy initiatives that are needed in order to successfully reverse the effects of climate change. Green Japan offers a nuanced and hopeful account of one nation's attempts at linking environmental sustainability and continued prosperity.
This book introduces some emerging functional foods that are natural resources with tremendous promise as nutraceuticals and pharmaceuticals. The author considers biodiversity and bioprospecting as a response to food security issues, drug-resistance, nutrition-poor diets and other problems, exploring the prospects of several under-utilized nutrients and bioactive repositories. Readers will discover biochemical makeups, validated health benefits, explanations of underlying mechanisms, hurdles in the path of popularity and promotion strategies. Chapters explore particular plants, seeds and fruits including the strawberry guava, opuntia fruits, the Carissa genus, grape seeds, quinoa and the milk thistle (Silybum), amongst others. They are considered as food sources where possible and from the perspective of the roles they can play in complementary and alternative medicine, such as in wound healing, antimicrobial activity, gastroprotective activity in treatment of cancers and as natural antioxidant sources. This rich compilation holds plausible solutions to a range of current issues and it endorses the much-needed goal of sustainability in terms of diet and drugs. It paves the path for further research and development on hitherto obscure natural resources. Scientists working in the area of food development, phytochemical and antioxidant analysis, bioprospecting of low-profile foods and in complementary and alternative medicine will find this work particularly valuable. It will also be of interest to the general reader with an interest in food science, food security, phytochemicals and functional food studies.
This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. " This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action ." Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. ""This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world."" Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK "
On the eve of the World Summit for Sustainable Development (WSSD), held in autumn 2002 in Johannesburg, South Africa, United Nations Secretary General Kofi Annan recommended five specific areas as focal points of discussion for the global forum: Water, energy, health, agriculture and biodiversity. In his address, "Towards a Sustainable Future," delivered just four months before the WSSD, Secretary General Annan contended that concrete progress in each of these areas, often referred to by their acronym WEHAB, would be key to improving the quality of life not only in the developing world but across the globe. For most people, I think it is fair to say that the inclusion of biodiversity in a list that focuses on basic human needs may not be self-evident. Water, energy, health and agriculture, yes. But why biodiversity? The truth is that biodiversity is just as critical to global well-being as water, energy, agriculture and health. This is because biodiversity both drives and shapes nature's intricate and dynamic structure in an enduring form and force that enables both current and future generations to enjoy its bounty.
Many attack pop culture as a crude 'sexual' and 'celebrity-based' culture that is purportedly bringing about the end of moral values. Renowned semiotician Marcel Danesi adds his signature insight to the debate by delving deep into pop culture through a consideration of symbols. Danesi's treatment of letters, such as the X in 'X-Rated,' the 'i' in 'iPod,' and other such symbols, reveals an ancient mythic structure that blends the sacred and profane dimensions of human psychic life. Danesi takes the reader on a remarkable exploration of the radical turns in American society, a society in which the search for pleasure and sexual expression often reign supreme. X-Rated! is a fascinating trip through what gives pop culture its secret appeal.
The Goodwin-Niering Center for Conservation Biology and Environmental Studies at Connecticut College is a comprehensive, interdisciplinary program that builds on one of the nation's leading undergraduate environmental studies programs. The C- ter fosters research, education, and curriculum development aimed at understanding contemporary ecological challenges. One of the major goals of the Goodwin-Niering Center is to enhance the understanding of both the College community and the general public with respect to ecological, political, social, and economic factors that affect natural resource use and preservation of natural ecosystems. To this end, the C- ter has offered six conferences at which academicians, representatives of federal and state government, people who depend on natural resources for their living, and in- viduals from non-government environmental organizations were brought together for an in-depth, interdisciplinary evaluation of important environmental issues. On April 6 and 7, 2007, the Center presented the Elizabeth Babbott Conant interdisciplinary conference on Saving Biological Diversity: Weighing the Protection of Endangered Species vs. Entire Ecosystems. The Beaver Brook Foundation; Audubon Connecticut, the state of?ce of the National Audubon Society; the Connecticut Chapter of The Nature Conservancy; Connecticut Forest and Park Association and the Connecticut Sea Grant College Program joined the Center as conference sponsors. During this two-day conference we learned about conservation and endangered species fromawiderange ofperspectives. Likeallof theconferences sponsored bythe Goodwin-Niering Center, this conference was broadly interdisciplinary, with pres- tations by economists, political scientists, and conservation biologists.
Consumers are not usually incorporated into the sociological concept of 'division of labour', but using the case of household recycling, this book shows why this foundational concept needs to be revised.
By their adoption of Agenda 21, most of the world's governments have acknowledged the need for sustainable development. This implies that new policies are needed, focusing on economic, social, cultural and ecological goals. At the same time, we also need to solve existing environmental and social problems, and prevent the occurrence of new ones. This volume presents, tests and illustrates a theoretically well-founded procedure for discovering regional opportunities for sustainable development, based on a systems approach to decision making. The procedure takes as its starting point the needs of the people involved, relating these to the measurement of available resources in order to find opportunities for multiple resource use and sustainable development. The needs of future generations and broader communities are taken into account throughout. The book studies regional planning and the implementation of plans, offering guidance and support to parties involved in debates on sustainable development, and improving the quality of their decision making.
"Legitimacy in International Society" addresses collective
legitimization of emergent norms at international meetings and its
effect on state behavior. Drawing mainly on constructivist
approaches in International Relations and social psychology, Isao
Miyaoka discusses the international and domestic sources of
legitimacy and the basic conditions under which collective
legitimization matters for norm adoption. Three case studies
examine Japan's responses to wildlife preservationist norms against
high seas driftnet fishing, scientific whaling and international
trade in African elephant ivory.
The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.
The Atlantic Forest is one of the 36 hotspots for biodiversity conservation worldwide. It is a unique, large biome (more than 3000 km in latitude; 2500 in longitude), marked by high biodiversity, high degree of endemic species and, at the same time, extremely threatened. Approximately 70% of the Brazilian population lives in the area of this biome, which makes the conflict between biodiversity conservation and the sustainability of the human population a relevant issue. This book aims to cover: 1) the historical characterization and geographic variation of the biome; 2) the distribution of the diversity of some relevant taxa; 3) the main threats to biodiversity, and 4) possible opportunities to ensure the biodiversity conservation, and the economic and social sustainability. Also, it is hoped that this book can be useful for those involved in the development of public policies aimed at the conservation of this important global biome.
Comparative Evaluations of Innovative Fisheries Management begins with a look at four places outside the European Union known for innovative management: New Zealand, Nova Scotia, Alaska and Iceland. Then the focus shifts to the success criteria related to specific disciplines including biological and social robustness, economic efficiency and impacts on management costs. Hypotheses are tested using data capable of generating useful results. The main conclusions include a retrospective of how key concepts defined and represented the various perspectives, skills and backgrounds that made up the multidisciplinary CEVIS project.
With an annual growth rate of over 35%, wind is the fastest growing energy source in the world today. As a result of intensive research and developmental efforts, the technology of generating energy from wind has significantly changed during the past five years. The book brings together all the latest aspects of wind energy conversion technology - right from the wind resource analysis to grid integration of the wind generated electricity. The chapters are contributed by academic and industrial experts having vast experience in these areas. Each chapter begins with an introduction explaining the current status of the technology and proceeds further to the advanced lever to cater for the needs of readers from different subject backgrounds. Extensive bibliography/references appended to each chapter give further guidance to the interested readers.
This book dealt with a number of issues under the broad subject matter of protected area focusing on the policy of collaborative management as a means to augment the forest conservation activities and enhance community development in Bangladesh. Studies covered in the book emerged with the success stories of protected area co-management, both in terms of community development and biodiversity conservation. Significant level of development was noticed in the socio-economic conditions of the surrounding communities. Empowerment and improved social dignity of women participants signifies the initiation of co-management approach. The principles of participatory governance were found reasonably well reflected in legal and policy frameworks. Based on the lessons from the studies, a general metaphysical model, namely Spider-web model of protected area co-management has been developed that can be potentially applicable in countries where local communities rely heavily on protected areas."
Her first night in a Tanzanian tent began with a prowling lion’s roar. Will the savage terrors open her eyes to an unseen world? Sue Tidwell lived in awe of Africa’s extraordinary wildlife. After years spent appreciating the animals in her imagination, the tenderhearted American hated the idea of joining her husband on a big game hunt. And getting attacked by blood-sucking tsetse flies the moment she stepped off the plane gave no hint of the mind-blowing change of perspective in her future… With her initial animosity turning into curiosity as they breathlessly tracked dangerous beasts, Sue formed a surprising bond with their young, government-assigned game scout. And as she became entranced by the tales and wisdom from the Masimba Camp crew, she was humbled by the mystery of the vilified safari and the people who relied on it for survival. Supplementing her own experiences on the elephant-rutted roads with local insights and scientific research into conservation efforts, Tidwell explores how her preconceived beliefs sluiced away under the deluge of reality. And with an evocative narrative peppered with self-deprecating humor, vivid imagery, and over ninety photos and illustrations, you’ll emerge forever changed by the truths this greenhorn found buried in a rugged and romantic landscape.
More than two third of the surface area of our planet is covered by oceans and assessment of the marine biodiversity is a challenging task. With the increasing global population, there is a tendency to exploit marine recourses for food, energy and other requirements. This puts pressure on the fragile marine environment and needs sustainable conservation efforts. Marine species identification using traditional taxonomical methods are often burdened with taxonomic controversies. Here in this book we will discuss the comparatively new concept of DNA barcoding and its significance in marine perspective. This molecular technique can be helpful in the assessment of cryptic species which are widespread in marine environment, and can also be used to link the different life cycle stages to the adult which is difficult to accomplish in marine ecosystems. Other advantages of DNA barcoding include authentication and safety assessment of seafood, wildlife forensics, conservation genetics and detection of invasive alien species (IAS). Global DNA barcoding efforts in the marine habitat include MarBOL, CeDAMar, CMarZ, SHARK-BOL, etc. DNA barcoding of different marine groups ranging from the microbes to mammals is to be revealed. In conjugation with newer and faster techniques like high throughput sequencing, DNA barcoding is serving as an effective modern tool in marine biodiversity assessment and conservation.
"Empire forestry"-the broadly shared forest management practice that emerged in the West in the nineteenth century-may have originated in Europe, but it would eventually reshape the landscapes of colonies around the world. Melding the approaches of environmental history and political ecology, Colonial Seeds in African Soil unravels the complex ways this dynamic played out in twentieth-century colonial Sierra Leone. While giving careful attention to topics such as forest reservation and exploitation, the volume moves beyond conservation practices and discourses, attending to the overlapping social, economic, and political contexts that have shaped approaches to forest management over time. |
