This book provides a comprehensive monograph of the family Humiraceae. It includes information on economic botany, conservation, phylogenetic relationships, taxonomic history, ecology, cytology, anatomy, and phytochemistry, among other topics. This volume is illustrated with line drawings, black and white photographs, and distribution maps. It was written by the world-leading authority on this plant group and contains a total of eight genera, 65 species, and 15 infraspecific taxa, with two new species described. This work is volume 123 in the Flora Neotropica book series (Lawrence M. Kelly, Editor-in-Chief). Flora Neotropica volumes provide taxonomic treatments of plant groups or families growing in the Americas between the Tropic of Cancer and the Tropic of Capricorn.
This book examines the development needs of protected areas with threatened ecological biodiversity to gain deeper understanding of the local perspective of protected area ecosystems. The study focuses on the case of Nech Sar National Park in Ethiopia, a protected area facing many development challenges due to human over-utilization of its resources and threats to wildlife. The conceptual framework developed by this research makes an academic contribution in the protection and sustainable development of national parks' natural capital, since it is designed to provide a systemic analysis of the problem by showing the extent and magnitude of human induced impacts on the natural capital of protected areas. In line with this, the application of the framework produces new and evidence-based findings which will help to improve the governance of protected areas as the research will provide park authorities with a practical tool in addressing the underlying causes of the degradation of national parks before the state of degradation of these resources reach its irreversible juncture. The book will help academicians and researchers to assess the state of biodiversity resources in protected areas using Nech Sar National Park as a representative example of a threatened area common throughout Africa, and will enable development practitioners and policy makers to devise appropriate strategies such as community participation in the governance of protected areas that could help to halt the degradation of resources in protected areas.
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 book describes and illustrates 300 species of free-living marine nematodes from the East China Sea and includes eighteen new species. Free-living marine nematode is the most dominant and diverse meiofaunal group in marine benthic habitats. It has strong adaptability and wide distribution, and plays a very important role in the material circulation and energy flow of benthic ecosystem. Up to now, about 7,000 species of free-living marine forms (attached to 2 Class, 8 Order, 86 Family, 662 genera) have been recorded around the world. Some 500 species have so far been reported from the sea areas of China. Among them, more than 300 species were identified from the East China Sea. The book will provide basic data and information of free-living marine nematodes for ecosystem management, protection and utilization of marine biological resources in the East China Sea.
The book contains detailed descriptions of the unique desert environment with particular emphasis on vegetation and survival strategies of plants. Nine expeditions through the Southwest of Western Australia over a period of 15 years triggered the interest of the authors to explore also some deserts in the region, which leads to three further excursions into the sandy dunes of the desert. Observations of plant life in the deserts focused not only on identifying plants, but also on gaining some understanding of the aboriginal desert people of centuries past, and their own survival strategies in such extreme conditions. Also part of the Canning Stock Route was followed and explored, but the most rewarding and interesting finds were done criss-crossing the desert away from highways, tracks, and paths. The most remote areas showed species richness and surviving strategies which by far exceeded expectations.
Comprising well over half of all known animal species, insects are the most successful organisms on the planet. Indeed, it is no exaggeration to say that one cannot study agriculture, biology, and the environment, without a basic understanding of entomology. Furthermore, insects are indispensable to advances in molecular biology and genetics, and their ongoing decline in many parts of the world has stimulated much research in the crucial roles they play in global ecosystems. However, the sheer diversity of insects can be a challenge to every newcomer to entomology. Most entomology textbooks tend to focus on insect biology, leaving readers with only a superficial idea of insect diversity and evolution, while others delve into too much detail that will deter the novice. In contrast, Essential Entomology has a clear taxonomic structure that provides readers with the necessary framework to understand the diversity, life history, and taxonomy of insects in a new light. This fully revised edition provides the most up-to-date guide to insects and includes all the major developments in molecular biology and palaeontology of the last 20 years. This textbook is an essential read for undergraduate and graduate students taking courses in entomology, agriculture, and forestry. It will also appeal to a broad academic audience of ecologists, conservationists, natural resource managers, as well as to the far more numerous general readers who are interested in wildlife, nature, and the environment. With these diverse audiences in mind, the straightforward and accessible style of the first edition has been maintained, technical jargon has been kept to a minimum, and sufficient background information is provided to enable the reader to follow the text with ease.
The fragmenting of habitats is endangering animal populations and degrading or destroying many plant populations throughout the world. To address this problem, conservationists have increasingly turned to biological corridors, areas of land set aside to facilitate the movement of species and ecological processes. However, while hundreds of corridor initiatives are under way worldwide, there is little practical information to guide their design, location, and management. "Applying Nature's Design" offers a comprehensive overview of current knowledge on corridors, their design, and their implementation. Anthony B. Anderson and Clinton N. Jenkins examine a variety of conceptual and practical issues associated with corridors and provide detailed case studies from around the world. Their work considers how to manage and govern corridors, how to build support among various interest groups for corridors, and the obstacles to implementation. In addition to assessing various environmental and ecological challenges, the authors are the first to consider the importance of socioeconomic and political issues in creating and maintaining corridors.
This open access book focuses on climate change, Indigenous reindeer husbandry, and the underlying concept of connecting the traditional knowledge of Indigenous reindeer herders in the Arctic with the latest research findings of the world's leading academics. The Arctic and sub-Arctic environment, climate, and biodiversity are changing in ways unprecedented in the long histories of the north, challenging traditional ways of life, well-being, and food security with legitimate concerns for the future of traditional Indigenous livelihoods. The book provides a clear and thorough overview of the potential problems caused by a warming climate on reindeer husbandry and how reindeer herders' knowledge should be brought to action. In particular, the predicted impacts of global warming on winter climate and the resilience of the reindeer herding communities are thoroughly discussed.
This book provides a comprehensive, global exploration of the scale, scope, threats, and drivers of wildlife trafficking from a criminological perspective. Building on the first edition, it takes into account the significant changes in the international context surrounding these issues since 2013. It provides new examples, updated statistics, and discusses the potential changes arising as a result of COVID-19 and the IPBES 2019 report. It also discusses the shift in trafficking 'hotspots' and the recent projects that have challenged responses to wildlife trafficking. It undertakes a distinctive exploration of who the victims and offenders of wildlife trafficking are as well as analysing the stakeholders who are involved in collaborative efforts to end this devastating green crime. It unpacks the security implications of wildlife trade and trafficking and possible responses and ways to combat it. It provides useful and timely information for social and environmental/life scientists, law enforcement, NGOs, and policy makers.
This volume builds on an international workshop held in 2019, inspired by James Lovelock's "The Revenge of Gaia - Why the Earth Is Fighting Back, and How We Can Still Save Humanity". It, therefore, understands the Gaia concept as an umbrella term for the living world that planet Earth is hosting for nearly 4 billion years. Humankind has intervened in this ecosystem since its emergence on the planet about 2.5 million years ago, often with painful consequences for itself. In its reactions, the Earth system follows only the laws of nature. Consequently, humanity needs to develop strategies for a sustainable Earth system. This volume presents a unique trans- and interdisciplinary variety of approaches to this challenge, offering philosophical considerations as well as practical medical research. It addresses a broad knowledgeable and general audience in environmental management, public administration, and higher education alike.
Medicinal plant research is an evergreen subject. There is a tremendous increase in popularity of herbal medicine in traditional medicine, ethnomedicine, modern medicine and as over the counter food supplements. Even after this increased demand, supply is neither uniform nor assured as most of these plants are collected from wild. In developing countries of tropical and subtropical regions where majority of herbal drugs are produced, this is not organised sector making it vulnerable to several malpractices, hence standardization of all aspects required. This has also negative impact on biodiversity and conservation of plants as well as supply of uniform material. This book is aimed to provide up to date information about sustainable use of selected medicinal plants, their active ingredients and efforts made to domesticate them to ensured uniform supply. Development of agrotechnology, biotechnology and cultivation practices using conventional and non-conventional methods are presented. Where these efforts will lead the medicinal plant research and future perspective are discussed. The chapters are written by well recognised group leaders in working in the field. The book contains topics on general biology of medicinal plants, their sustainable use and, cultivation and domestication efforts. A uniform chapter structure has been designed to keep consistency. The book will be useful for academicians, agriculturists, biotechnologists and researcher, and industries involved in manufacturing herbal drugs and supplementary products.
This book addresses the multidisciplinary challenges in biodiversity conservation with a focus on wildlife crime and how forensic tools can be applied to protect species and preserve ecosystems. Illustrated by numerous case studies covering different geographical regions and species the book introduces to the fundamentals of biodiversity conflicts, outlines the unique challenges of wildlife crime scenes and reviews latest techniques in environmental forensics, such as DNA metagenomics. In addition, the volume explores the socio-economic perspective of biodiversity protection and provides an overview of national and international conservation laws. The field of conservation medicine stresses the importance of recognizing that human health, animal health, and ecosystem health are inextricably interdependent and the book serves as important contribution towards achieving the UN Sustainable Developmental Goals, in particular SDG 15, Life on Land. The book addresses graduate students, scientists and veterinary professionals working in wildlife research and conservation biology.
Stream Ecology: Structure and Function of Running Waters is designed to serve as a textbook for advanced undergraduate and graduate students, and as a reference source for specialists in stream ecology and related fields. This Third Edition is thoroughly updated and expanded to incorporate significant advances in our understanding of environmental factors, biological interactions, and ecosystem processes, and how these vary with hydrological, geomorphological, and landscape setting. The broad diversity of running waters - from torrential mountain brooks, to large, lowland rivers, to great river systems whose basins occupy sub-continents - makes river ecosystems appear overwhelming complex. A central theme of this book is that although the settings are often unique, the processes at work in running waters are general and increasingly well understood. Even as our scientific understanding of stream ecosystems rapidly advances, the pressures arising from diverse human activities continue to threaten the health of rivers worldwide. This book presents vital new findings concerning human impacts, and the advances in pollution control, flow management, restoration, and conservation planning that point to practical solutions. Reviews of the first edition: ".. an unusually lucid and judicious reassessment of the state of stream ecology" Science Magazine "..provides an excellent introduction to the area for advanced undergraduates and graduate students..." Limnology & Oceanography "... a valuable reference for all those interested in the ecology of running waters." Transactions of the American Fisheries Society Reviews of the second edition: "Overall, a must for the field centre and a good starter text in stream ecology." (TEN News, October, 2007) "Highly recommended. Upper-division undergraduates through faculty." (P. R. Pinet, CHOICE, Vol. 45 (7), 2008) "... a very good, fluidly readable book which contains the latest key scientific knowledge of the ecology of running waters." (Daniel Graeber, International Review of Hydrobiology, Vol. 94 (2), 2009)
How to decelerate loss of global biodiversity is one of the greatest challenges of our generation. Reproductive technologies have enormous potential to assist the recovery of species by enhancing reproductive output, facilitating genetic management, and supporting reintroduction of threatened species. Of particular value are cryopreservation technologies coupled with the establishment of global gene banks to conserve, in perpetuity, the remaining extant genetic diversity of threatened amphibians. Reproductive Technologies and Biobanking for the Conservation of Amphibians brings together leading experts in the field to provide a comprehensive overview of current best practices, summarise technological advancements, and present a framework for facilitating the integration of reproductive technologies and biobanking into conservation breeding programs for threatened amphibians. It is an invaluable reference for the next generation of conservation practitioners: captive breeding facilities, researchers, and policy-makers involved with biodiversity conservation
This book, as a part of a series of CERES publications, provides a multi-regional and cross-sectoral analysis of food and water security, especially in the era of climate risks, biodiversity loss, pressure on scarce resources, especially land and water, increasing global population, and changing dietary preferences. It includes both conceptual research and empirically-based studies, which provides context-specific analyses and recommendations based on a variety of case studies from Africa, Middle East, and Asia regarding the fostering of long-term resilience of food and water security. The core approach of the volume consists of: assessing the structural drivers affecting the vulnerability of food and water security, under the persistence of current trends; identifying the best solutions and practices to enhance the climate resilience for food and water security; and fostering climate adaptation and biodiversity protection for food and water security.
Arctic and Subarctic North America is particularly affected by climate change, where average temperatures are rising three times faster than the global average. Documenting the changing climate/environment of the north requires a structured knowledge of indicator taxa that reflect the effects of climate changes.Aleocharine beetles are a dominant group of forest insects, which are being used in many projects as indicators of environmental change. Many species are forest specialists restricted to certain microhabitats, some are generalists and others are open habitat specialists. They represent many ecological niches and, as such, are good indicators for many other species as well. The majority of Canadian aleocharine beetle species (about 600 spp.) has been studied and published by Jan Klimaszewski et al. (2018, 2020), mainly from southern, central, and western Canada, while the northern taxa remain poorly known and documented. The aim of the present book is to summarize the knowledge on this insect group in the Arctic and Subarctic North America and to provide a diagnostic and ecological tool for scientists studying and monitoring insects in northern Canada and Alaska. The book includes a review of the literature, information on 238 species and their habitats, taxonomic review, images, and identification tools.
The Bahia Blanca Estuary is one of the largest coastal systems in Atlantic South America. This mesotidal estuary, situated in a sharp transition between humid subtropical and semiarid climates, has a unique combination of large interannual climatic variations. The estuarine area encompasses roughly 2300 square kilometers and is composed of wide expanses of intertidal flats, salt marshes, and emerged islands, which create intricate landscape patterns. Natural environments in the estuary sustain a high concentration of marine and terrestrial species, including endemic, threatened, and endangered fish and shorebirds. Puerto Cuatreros, in the inner zone of the estuary, hosts a permanent marine research station, whose records span more than 30 years of biophysical variables, and represent one of the largest time series of ecological data in South America. Beyond its ecological relevance, the Bahia Blanca Estuary is under increasing anthropogenic pressure from large urban settlements, industrial developments and harbors, raising the question of how to balance conservation and development. The Bahia Blanca Estuary: Ecology and Biodiversity offers a comprehensive review of life in the ecosystems of the estuary. The book is divided into five major sections, the first of which provides a description of the regional setting and covers key aspects of estuarine dynamics. The three following sections are dedicated to different habitat types and, within each section, the chapters are organized around major functional groups from pelagic and benthic environments. The fifth and final section covers issues related to management and conservation. Overall, the book provides essential and up-to-date reference material on the biodiversity and ecosystem processes of the Bahia Blanca Estuary, and will appeal to a broad international audience.
The book discusses the ways in which high hydrostatic pressure (i.e. water pressure) affects all grades of life which thrive at pressures much greater those in our normal environment. The deep sea is the best known high pressure environment, where pressures reach a thousand times greater than those at the surface, yet it is populated by a variety of animals and microorganisms. The earth's crust supports microorganisms which live in water filled pores at high pressure. In addition, the load bearing joints of animals like ourselves experience pulses of hydrostatic pressure of a magnitude similar to the pressure at mid ocean depths. These pressures affect molecular structures and biochemical reactions. Basic cellular processes are drastically affected - the growth and division of cells, the way nerves conduct impulses and the chemical reactions which provide energy. Adaptation to high pressure also occurs in complex physiological systems such as those which provide buoyancy. Probably the greatest challenge to our understanding of adaptation to high pressure is the stabilisation of the nervous system of deep sea animals to avoid convulsions which pressure causes in shallow water animals. Additionally the book provides insight into the engineering required to study life at high pressure: equipment which can trap small deep sea animals and retrieve them at their high pressure, equivalent equipment for microorganisms, laboratory microscopes which can focus on living cells under high pressure, incubators for bacteria which require high pressure to grow, high pressure aquaria for marine animals and lastly and briefly, manned and unmanned submersible vessels, Landers and deep drill hole sampling. Rather like the organisms studied many laboratory instruments have been adapted to function at high pressure.
Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.
Forests cover thirty-one percent of the world's land surface, provide habitats for animals, livelihoods for humans, and generate household income in rural areas of developing countries. They also supply other essential amenities, for instance, they filter water, control water runoff, protect soil erosion, regulate climate, store nutrients, and facilitate countless non-timber forest products (NTFPs). The main NTFPs comprise herbs, grasses, climbers, shrubs, and trees used for food, fodder, fuel, beverages, medicine, animals, birds and fish for food, fur, and feathers, as well as their products, like honey, lac, silk, and paper. At present, these products play an important role in the daily life and well-being of millions of people worldwide. Hence the forest and its products are very valuable and often NTFPs are considered as the 'potential pillars of sustainable forestry'. NTFPs items like food, herbal drugs, forage, fuel-wood, fountain, fibre, bamboo, rattans, leaves, barks, resins, and gums have been continuously used and exploited by humans. Wild edible foods are rich in terms of vitamins, protein, fat, sugars, and minerals. Additionally, some NTFPs are used as important raw materials for pharmaceutical industries. Numerous industry-based NTFPs are now being exported in considerable quantities by developing countries. Accordingly, this sector facilitates employment opportunities in remote rural areas. So, these developments also highlight the role of NTFPs in poverty alleviation in different regions of the world. This book provides a wide spectrum of information on NTFPs, including important references. We hope that the compendium of chapters in this book will be very useful as a reference book for graduate and postgraduate students and researchers in various disciplines of forestry, botany, medical botany, economic botany, ecology, agroforestry, and biology. Additionally, this book should be useful for scientists, experts, and consultants associated with the forestry sector.
There has been growing academic interest in local food plants. This is a subject that lies at the frontiers of knowledge of various areas, such as environmental sciences, nutrition, public health, and humanities. To date, however, we do not have a book bringing these multi-disciplinary perspectives to bear on this complex field. This book presents the current state of knowledge on local Brazilian food plants through a multidisciplinary approach, including an overview of food plants in Brazil, as well as comprehensive nutritional data. It compiles basic theories on the interrelationship between biodiversity and food and nutrition security, as well as ethnobotanical knowledge of local Brazilian food plants. Additionally, this title provides various methods of learning and teaching the subject, including through social media, artificial intelligence, and through workshops, among others.
This book is focused on the marine mammalian groups the Otariidae and the Odobenidae, otherwise known as fur seals, sea lions and the walrus. In 30 chapters, more than 60 authors from 30 institutions and 13 nationalities, discuss a broad suite of topics from maternal care and mating behavior, through play, cognition and personality, to adaptation to life in the Anthropocene. The authors explore the behaviors that have allowed these semi-aquatic mammals to thrive in the marine realm. Many populations have recovered following historical decimation, with interesting evolutionary consequences which are explored. Detailed, selected, individual species descriptions are also provided, showcasing the behavioral diversity of this engaging, adaptive and highly successful group of marine mammals.
This book owes a great deal to the outstanding universal value of the natural heritage of Hubei Shennongjia, which offers an outstanding example of the ongoing ecological processes occurring in the development of intact subtropical mixed broad-leaved evergreen and deciduous forests in the northern hemisphere. The book demonstrates the value from the typical example of mountain altitudinal biological zones in the Oriental Deciduous Forest Biogeographical Province, and the vital origin location for global temperate flora, harboring the highest concentration of global temperate genera. Moreover, the heritage value in exceptional biodiversity and key habitat for numerous relic, rare, endangered, endemic, and type specimen species are presented. The richness of deciduous woody species in Shennongjia is the highest in the world.
Published in three other languages and growing, "Managing Biodiversity in Agricultural Ecosystems" takes a look at how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. The volume includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels. Chapters cover the assessment and farmer management practices for crop, livestock, aquatic, and associated diversity (such as pollinators and soil microorganisms) in agricultural ecosystems; examine the potential role of diversity in minimizing pest and disease pressures; and present studies that exemplify the potential nutritional, ecosystem service, and financial values of this diversity under changing economic and environmental conditions. The volume contains perspectives that combine the thinking of social and biological scientists. Inappropriate or excessive use of inputs can cause damage to biodiversity within agricultural ecosystems and compromise future productivity. This book features numerous case studies that show how farmers have used alternative approaches to manage biodiversity to enhance the stability, resilience, and productivity of their farms, pointing the way toward improved biodiversity on a global scale. As custodians of the world's agricultural biodiversity, farmers are fully invested in ways to create, sustain, and assist in the evolution and adaptation of a variety of plant and animal species. Thus this text is mandatory reading for conservationists, environmentalists, botanists, zoologists, geneticists, and anyone interested in the health of our ecosystem. |
