This book is the final installation in a three-volume series synthesizing 30 years of mercury research in the Florida Everglades. The first part of this book evaluates the occurrence of trends in both biota mercury concentrations and atmospheric mercury deposition. Through both empirical and deterministic analyses, the likely drivers of biota trends are identified. These analyses help lay the predicate for devising an overall strategy to mitigate and manage the Everglades mercury problem. The book concludes with a model analysis of the likely benefits and uncertainty attendant with implementing the leading candidate strategy for best reducing the Everglades mercury problem.
This work examines the waters of marine ports as unique integrated aquatic ecosystems. It regards marine ports as entities comprising components of natural and anthropogenic origin, including pelagic, periphytal and benthal subsystems. Using selected Black and Azov Sea ports as examples, the book discusses the hydrodynamics and water exchange, which are weakened in ports compared with open coastal zones. It reflects consequences of the presence of hydrobionts and the accumulation of organic matter, which are promoted by the variety of hard substrata and the absence of fishery. The book is divided into five main chapters. The first chapter describes the general characteristics of the marine ports at the northern coast of the Black and Azov Seas and their shipping channels. Chapters 2 to 4 discuss the main abiotic and biotic peculiarities of the pelagial, periphytal and benthal subsystems of those marine ports, and chapter 5 deals with tropho-dynamic processes in their ecosystems. A concluding section reflects recommendations how the ecosystems of ports in non-tidal seas may be ameliorated.
Modern industrial agriculture is not sustainable because of its heavy reliance on petroleum, a non-renewable source of the energy used in farming, and because of pollution caused by petroleum products such as fertilizers and pesticides. A systems analysis of farming suggests that agriculture will be more sustainable when services of nature, such as nutrient recycling by soil micro-organisms and natural controls of insects, replace the services now provided by energy from petroleum. Examples are drawn from the Southeastern USA, but lessons learned can be applied worldwide.
This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host's capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host's protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.
This volume summarizes recent advances in environmental microbiology by providing fascinating insights into the diversity of microbial life that exists on our planet. The first two chapters present theoretical perspectives that help to consolidate our understanding of evolution as an adaptive process by which the niche and habitat of each species develop in a manner that interconnects individual components of an ecosystem. This results in communities that function by simultaneously coordinating their metabolic and physiologic actions. The third contribution addresses the fossil record of microorganisms, and the subsequent chapters then introduce the microbial life that currently exists in various terrestrial and aquatic ecosystems. Coverage of the geosphere addresses endolithic organisms, life in caves and the deep continental biosphere, including how subsurface microbial life may impact spent nuclear fuel repositories. The discussion of the hydrosphere includes hypersaline environments and arctic food chains. By better understanding examples from the micro biosphere, we can elucidate the many ways in which the niches of different species, both large and small, interconnect within the overlapping habitats of this world, which is governed by its microorganisms.
The list of challenges facing nonhuman primates in the 21st century is a long one. The expansion of palm oil plantations to feed a growing consumer class is eating away at ape and monkey habitats in Southeast Asia and Central Africa. Lemurs are hunted for food in the poorest parts of Madagascar while monkeys are used as medicine in Brazil. Traditional cultural beliefs are maintaining demand for animal body parts in West African markets while viral YouTube videos of "cute" and "cuddly" lorises have increased their market value as pets and endangered their populations. These and other issues are addressed in this book by leading researchers in the field of ethnoprimatology, the study of human/nonhuman primate interactions that combines traditional primatological methodologies with cultural anthropology in an effort to better understand the nuances of our economic, ritualistic, and ecologic relationships.
This book brings together the latest information on the rapid advances and developments in the field of aquatic ecology. India is very rich in terms of biological diversity due to its wide range of habitats and climatic conditions. It is home to as much as 7 per cent of the world's animal species, although it only accounts for about 2 per cent of the total landmass. The present work on biodiversity, ecology and conservation of aquatic resources represents original research in the field of aquatic biodiversity, wetland ecology and its applications with reference to the country's aquatic resources. There are 19 chapters, each contributed by an expert in his/her particular field and offering novel approaches to various topics in the area of aquatic ecosystems.
This book highlights both the diversity of perspectives and approaches to Arctic research and the inherent interdisciplinary nature of studying and understanding this incomparable region. The chapters are divided into four liberally-defined sections to provide space for dynamic interpretation and dialogue in search of sustainable solutions to the issues facing the Arctic. From governance to technology, scientific research to social systems, human health to economic development, the authors discuss fundamental questions while looking toward the Arctic's future. Whether the reader is well-versed in the history and complexity of Arctic policy or looking for an insightful introduction to the vast world of Arctic research, everyone will find answers that lead to new questions and even more discoveries in these pages, laying the foundation for tomorrow's discussion on the future of the Arctic. The Arctic's unique geographic and political characteristics pose questions for the international community, indigenous peoples, and economic interests not easily answered through traditional concepts. To that end, the Arctic Summer College has been engaging leading professionals, students, scholars, and policy makers from across the globe to exchange ideas and support further investigation into the Arctic. A joint venture between Ecologic Institute US and Ecologic Institute Berlin (Germany), the College participates at the annual Arctic Circle Assembly in Reykjavik, Iceland, and continues to be at the forefront of international collaboration in this critical area of economic, political, environmental, and humanitarian development.
Drylands in East Asia (DEA) are home to more than one billion people with an environment vulnerable to natural and anthropogenic changes. One of the critical needs in the region is to fully understand how dryland ecosystems respond to the changing climate and human activities in order to develop strategies to cope with continued climate change. This book provides state-of-the-art knowledge and information on drylands ecosystem dynamics, changing climate, society, and land use in the region. In addition to the synthesis of the existing research and knowledge of DEA, the book provides a role model for regional ecological assessment. With a wide spectrum of contributions from experts around the globe, the book should be of interest to researchers and students both internationally and in East Asia. Lessons learned from this synthesis effort in DEA should be useful for developing climate adaptation strategies for other similar regions around the globe.

The book is divided into 15 chapters that cover various aspects of microorganism-based biotechnology, including recent methodologies such as advanced molecular techniques, as well developments in classical microbiological techniques. The authors also explain how the latest and classical techniques are being used in modern-day microbial biotechnology. All chapters were written by experts from prominent universities, research laboratories, and institutes around the globe. Above all, they focus on recent advances in microbial technology that promote the welfare of living beings and the environment.
Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.
Deep inside caves, at the bottoms of oceans and lakes, beneath the ground: these concealed habitats are absent of sunlight. This strange and fascinating world of complete darkness is not a solitary place-it is inhabited by millions of life forms. Yet most humans-creatures of daylight-have never seen any of them. Until now. In this fascinating-sometimes eerie-book, extreme wildlife photographer and scientist Dante Fenolio brings the denizens of these shadowy haunts into focus. Life in the Dark shows us the many ways in which life forms have adapted to lightless environments, including refinements of senses, evolution of unique body parts, and illumination using "biological flashlights." With more than 200 mesmerizing color photographs, Life in the Dark unveils bizarre creatures like the firefly squid, the giant Amazonian catfish, the Chinese cavefish, and even the human bot fly, which lives in the darkness beneath its host's skin. Fenolio's rich and vibrant images shed new light on the world's fascinating creatures of darkness.
Large terrestrial mammalian herbivores play critical roles in ecosystems by acting as regulators of energy and nutrient cycles, modulators of plant community composition and grassland-woodland transitions, agents of seed dispersal, and as prey for large carnivores. Though large herbivores represent a prominent component of mammalian assemblages throughout South and Southeast Asia, little is known about their roles in ecosystems in the region. This volume presents, for the first time, a collection of studies on the ecology of the rich and diverse large herbivore assemblages of South and Southeast Asia. Prepared by experts on herbivores of the region, it covers a comprehensive range of topics, including their evolutionary history, behavioural, nutritional, and population ecology, patterns of diversity across environmental gradients, roles as seed dispersers and regulators of plant growth, community compositions, and their conservation in the face of hunting and global change.
How can cultivated plant biodiversity contribute to the transformation and the "ecologization" of agriculture in Southern countries? Based on extensive field work in the Southern countries, a great deal of scientific progress is presented in all areas affecting agriculture (agronomy, plant breeding and crop protection, cultivation systems, etc.) in order to intensify the ecological processes in cultivated plots and at the scale of rural landscapes.
Found in every plant species, the diversity of endophytic micro-organisms can be extremely high within different plant organs and tissue types. In trees, their ecological roles with respect to host tree can vary from latent pathogens or saprophytes to neutral commensalists and mutualists. Given their high diversity, and their bio-active nature, endophytes are currently being associated with a role in tree health against insect herbivores and fungal pathogens, as well as improving tree properties in phytoremediation. Meanwhile there is increasing interest in the potential of some tree endophytes as new sources of drug compounds. The first book on tree endophytes in several years, and containing contributions from leading authors in the field, this book provides an important reference text for professional researchers and advanced students.

It begins with a basic introduction to the nature of and mechanistic benefits derived from symbiotic associations. Taking that background knowledge as the starting point, the next sections include chapters that examine representative examples of coevolutionary associations that have developed between species of microbes, as well as associations between microbes and plants. The authors conclude with a section covering a broad range of associations between microbes and invertebrate animals, in which they discuss the spectrum of hosts, with examples ranging from bryozoans and corals to nematodes, arthropods, and cephalopods. Join the authors on this journey of understanding!
This book provides excellent techniques for detecting and evaluating biofilms: sticky films on materials that are formed by bacterial activity and produce a range of industrial and medical problems such as corrosion, sanitary problems, and infections. Accordingly, it is essential to control biofilms and to establish appropriate countermeasures, from both industrial and medical viewpoints. This book offers valuable, detailed information on these countermeasures. It also discusses the fundamentals of biofilms, relates various substrates to biofilms, and presents a variety of biofilm reactors. However, the most important feature of this book (unlike others on the market) is its clear focus on addressing the practical aspects from an engineering viewpoint. Therefore, it offers an excellent practical guide for engineers and researchers in various fields, and can also be used as a great academic textbook.
Arising from a scientific conference marking the 100th anniversary of her birth, this book honors the life and work of the social scientist and diplomat Ester Boserup, who blazed new trails in her interdisciplinary approach to development and sustainability.
Feeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio-economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro-ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support. We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.
