Despite their rich fossil history, there are only four surviving species of sirenians or sea cows, the only fully aquatic herbivorous mammals. The three species of manatees and the dugong live in the coastal waters rivers and lakes of more than 80 tropical and subtropical countries and are all on the IUCN Red List of Threatened Species. This book examines sirenian conservation biology through the lens of their behavioral ecology and ethology. Sirenian feeding, diving, movement, social and reproductive behaviors are reviewed by an international team of scientists from eight countries, with an emphasis on data gathered in the past 15 years.

The plant species that humans rely upon have an extended family of wild counterparts that are an important source of genetic diversity used to breed productive crops. These wild and weedy cousins are valuable as a resource for adapting our food, forage, industrial and other crops to climate change. Many wild plant species are also directly used, especially for revegetation, and as medicinal and ornamental plants. North America is rich in these wild plant genetic resources. This book is a valuable reference that describes the important crop wild relatives and wild utilized species found in Canada, the United States and Mexico. The book highlights efforts taken by these countries to conserve and use wild resources and provides essential information on best practices for collecting and conserving them. Numerous maps using up-to-date information and methods illustrate the distribution of important species, and supplement detailed description on the potential value these resources have to agriculture, as well as their conservation statuses and needs. There is broad recognition of the urgent need to conserve plant diversity; however, a small fraction of wild species is distinguished by their potential to support agricultural production. Many of these species are common, even weedy, and are easily overshadowed by rare or endangered plants. Nevertheless, because of their genetic proximity to agriculturally important crops or direct use, they deserve to be recognized, celebrated, conserved, and made available to support food and agricultural security. This comprehensive two-volume reference will be valuable for students and scientists interested in economic botany, and for practitioners at all levels tasked with conserving plant biodiversity.

'Inspiring. [...] Crammed with lively interviews and grounded examples' Ashish Kothari, founder of Kalpavriksh Permaculture is an environmental movement that makes us reevaluate what it means to be sustainable. Through innovative agriculture and settlement design, the movement creates new communities that are harmonious with nature. It has grown from humble origins on a farm in 1970s Australia and flourished into a worldwide movement that confronts industrial capitalism. The Politics of Permaculture is one of the first books to unpack the theory and practice of this social movement that looks to challenge the status quo. Drawing upon the rich seam of publications and online communities from the movement as well as extensive interviews with permaculture practitioners and organisations from around the world, Leahy explains the ways permaculture is understood and practiced in different contexts. In the face of extreme environmental degradation and catastrophic climate change, we urgently need a new way of living.

In the early 1920s, in many a sawmill town across the South, the last quitting-time whistle signaled the cutting of the last log of a company's timber holdings and the end of an era in southern lumbering. It marked the end as well of the great primeval forest that covered most of the South when Europeans first invaded it. Much of the first forest, despite the labors of pioneer loggers, remained intact after the Civil War. But after the restrictions of the Southern Homestead Act were removed in 1876, lumbermen and speculators rushed in to acquire millions of acres of virgin woodland for minimal outlays. The frantic harvest of the South's first forest began; it was not to end until thousands of square miles lay denuded and desolate, their fragile soils -- like those of the abandoned cotton lands -- exposed to rapid destruction by the elements. With the end of the sawmill era and the collapse of the southern farm economy, the emigration routes from the South to the industrial cities of the North and Midwest were thronged with people forced from the land. Yet in the first quarter of this century, even as the destruction of forest and land continued, a day of renewal was dawning. The rise of the conservation movement, the beginnings of the national forests, the development of scientific forestry and establishment of forest schools, the advance of chemical research into the use of wood pulp -- all converged even as the 1930s brought to the South the sweeping reclamation programs of the Civilian Conservation Corps and the Tennessee Valley Authority; in their wake came a new generation of wood-using industries concerned not so much with the immediate exploitation of timber as with the maintenance of a renewable resource. In The Greening of the South, this dramatic story is told by one of the participants in the renewal of the forest. Thomas D. Clark, author of many books about southern history, is also an active timber producer on lands in both Kentucky and South Carolina

This captivating book simply and engagingly captures the vital role forests play in combating the effects of climate change. The reasons for the current and historical demise of the forest are clearly outlined, followed by a fascinating insight into how a forest works to help the local and global environment. There is a solution to global warming which is realistic, attainable and beneficial to the Earth and her inhabitants. Bill Liao and WeForest's laudable goals of making the earth cooler, alleviating poverty and restoring eco-systems are enshrined in the case studies from around the world; vividly demonstrating reasons to be hopeful.

Soils have been called the most complex microbial ecosystems on Earth. A single gram of soil can harbor millions of microbial cells and thousands of species. However, certain soil environments, such as those experiencing dramatic change exposing new initial soils or that are limited in precipitation, limit the number of species able to survive in these systems. In this respect, these environments offer unparalleled opportunities to uncover the factors that control the development and maintenance of complex microbial ecosystems. This book collects chapters that discuss the abiotic factors that structure arid and initial soil communities as well as the diversity and structure of the biological communities in these soils from viruses to plants.

In this book the authors have applied research knowledge to the solution of practical problems facing wildlife conservation in freshwater habitats. Subjects covered include: evaluation of the conservation interest of sites; practical protection and management of freshwater habitats; species conservation.

Reflecting a range of different landscapes and their inhabitants, and emphasizing the human voice and condition throughout, The Gulf South brings to light a region whose influence on American commerce and culture reaches far beyond its geographical boundaries. This volume encourages readers to consider how we choose to characterize the environment and its degradation through language, and how these accounts affect our thinking and planning for the future.

State of Disaster: A Historical Geography of Louisiana's Land Loss Crisis explores Louisiana's protracted efforts to restore and protect its coastal marshes, nearly always with minimal regard for the people displaced by those efforts. As Craig E. Colten shows, the state's coastal restoration plan seeks to protect cities and industry but sacrifices the coastal dwellers who have maintained their presence in this perilous place for centuries. This historical geography examines in turn the adaptive capacity of those living through repeated waves of calamity; the numerous disjointed environmental management regimes that contributed to the current crisis; the cartographic visualizations of land loss used to activate public coastal policy; and the phases of public input that nevertheless failed to give voice to the citizens most impacted by various environmental management strategies. In closing, Colten situates Louisiana's experience within broader discussions of climate change and recovery from repeated crises.

Get submerged in the amazing world of sharks! Your expert host, award-winning marine biologist Dr. David Shiffman, will show you how-and why-we should protect these mysterious, misunderstood guardians of the ocean. Sharks are some of the most fascinating, most ecologically important, most threatened, and most misunderstood animals on Earth. More often feared than revered, their role as predators of the deep have earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us-they're in danger from us. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman explains why it's crucial that we overcome our misconceptions and rise above cinematic jump scares to embrace sharks as the imperiled and elegant ocean guardians they really are. Sharing his own fascinating experiences working with sharks, Shiffman tells us * why healthy shark populations are a must for supporting ocean ecosystems-and the coastal economies that depend on them * why we're in danger of losing many shark species forever * what scientists, conservationists, and readers can do to help save these iconic predators * why so much of what you've heard about sharks and how to save them is wrong Exploring the core tenets of shark conservation science and policy, Shiffman synthesizes decades of scientific research and policymaking, weaving it into a narrative full of humor and adventure. Touching on everything from Shark Week to shark fin soup, overfishing to marine sanctuaries, Shiffman reveals why sharks are in trouble, why we should care, and how we can save them. Perfect for shark enthusiasts, Why Sharks Matter is an approachable, informative guide to the world of shark conservation and the passionate, fascinating, brilliant people who work to understand and protect our oceans. This fun read will have you looking at sharks with a fresh perspective and an understanding that the survival of sharks is crucial to the survival of another apex predator-ourselves.

This book brings together the latest information on tropical ungulates in different Latin American countries. These animals are not only important from the point of view of their role in different ecosystems, but also have cultural value for people. The book also discusses topics such as habitat transformation and hunting as these species are an important source of food in many places. Addressing ungulate natural communities in diverse ecosystems and countries, the book provides information on specific aspects of each of the most representative species, and highlights topics to help readers better understand these species and develop effective management and conservation strategies. The information presented also reveals the need for more knowledge and will hopefully provide the incentive for continued studies on this important group of animals. This publication serves as a reference for academic research on ungulate ecology, behavior and dynamics, as well as the basis for conservation strategies.

Marine Animal Forests (MAFs) are spread all over the world. Composed by suspension feeding organisms (e.g. corals, gorgonians, sponges, bryozoans, bivalves, etc.), MAFs constitute a vast number of marine ecosystems such as coral reefs, cold water corals, sponge grounds, bivalve beds, etc. The surface covered by these systems is prominent (at the scale of the oceans of the planet), though poorly known. In a previous book (Marine Animal Forests, the ecology of benthic biodiversity hotspots), several aspects of the MAFs were described and discussed, building the basis for a holistic approach with the aim of putting these shallow and deep sea ecosystems under a common umbrella. The main target of the present book is to identify and address important topics which were not covered in the previous three volumes. Bryozoans or Polychaeta, for example, are treated in this volume, as well as hydrothermal vents ecosystems and submarine caves, the chemical ecology in MAFs or the nursery effect on these ecosystems. The vastity of the MAF concept opens new insights in the biology, physiology, biodiversity of the organisms structuring these highly biodiverse ecosystems and on the dangers threatening them (such as microplastics or the role of invasive species as an impact of their trophic ecology or distribution). In a fast changing world, in which the complexity of MAFs is at risk, we propose an in-depth analysis of many aspects that may be inspirational for future research lines in marine biology and ecology.

Environmental and specific diversity in the Chihuahuan desert in general, and in the Cuatro Cienegas Basin in particular, has long been recognized as outstanding. This book provides a global ecological overview, together with in-depth studies of specific processes. The Chihuahuan desert is the warmest in North America, and has a complex geologic, climatic and biogeographical history, which affects today's distribution of vegetation and plants and generates complex phylogeographic patterns. The high number of endemic species reflects this complex set of traits. The modern distribution of environments, including aquatic and subaquatic systems, riparian environments, gypsum dunes and gypsum-rich soils, low levels of phosphorous and organic matter, and high salinity combined with an extreme climate call for a range of adaptations. Plants are distributed in a patchy pattern based on punctual variations, and many of them respond to different resources and conditions with considerable morphological plasticity. In terms of physiological, morphological and ecological variability, cacti were identified as the most important group in specific environments like bajadas, characterized by high diversity values, while gypsophytes and gypsovagues of different phylogenies, including species with restricted distribution and endemics.

The last few decades have seen a rapid growth of interest in the mangrove ecosystems. This is due, on the one hand, to the perception that mangrove ecosystems are valuable resources, and, on the other hand, due to vested economic interests. There is an accelerated rate of destruction of mangroves worldwide. Almost all nations of the world tropical belt are concerned with the conservation of this natural wealth, but surreptitiously permit the misuse of mangroves for quick monetary returns unabatedly. The scientific community and decision makers of many nations are now in a state of alert, requesting sound directives for the sustainable use of mangroves worldwide. The present publication is an attempt to present in an organized manner the present state of knowledge which could be useful for decision makers and of interest to all those who see the ecological and economical potential of the various types of mangrove ecosystems.

The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.

This book presents the outcomes of the 2017 national workshop and international conference organized by CEENR of ISEC, Bengaluru and Assam University Silchar. Addressing the threats to biodiversity and sustainable development resulting from the impacts of human induced pressures on ecosystems and global-warming-driven climate change is a major challenge. It requires increased knowledge and an enhanced information base in order to devise local policies to improve the adaptive capacity of vulnerable socio-ecological systems in developing countries. In this context, the book presents research that has the potential to benefit the environment and empower communities. It appeals to researchers investigating diverse aspects of socio-ecological-biological systems to create strategies for resource use, conservation and management to ensure sustainability.

This highly topical study of tropical deforestation reports on the first phase of a large, integrated, multi-institutional, and team-based study. Based in Mexico, it is designed to understand and project land changes in a development frontier that pits the rapidly growing needs of smallholder farmers to cut down forests for cultivation against federally sponsored initiatives committed to various international programmes of forest preservation and complementary economic programmes.
