This book has been developed to provide a detailed discussion of probiotics, which have been evaluated for use predominantly in fish and shellfish aquaculture. This book highlights strengths and weaknesses in knowledge and discusses gaps that need to be addressed. There has been a great deal of research concerning the use of probiotics in aquaculture. To date, a wide range of Gram-positive and Gram-negative bacteria and some eukaryotes, i.e. yeasts and unicellular algae, has been reported to be beneficial to aquatic hosts. Following oral uptake, benefit includes improved growth performance and protection against many bacteria and some parasitic diseases. This book will be suitable for scientists, veterinarians, professionals, and senior students involved in aquaculture.

Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category Lesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates that they have been persistently decreasing in number since the Dust Bowl of the 1930s dramatically affected their core range. In May of 2014, the United States Fish and Wildlife Service listed Lesser Prairie-Chickens as a threatened species, granting them federal protection under the Endangered Species Act, which included a special rule recognizing significant conservation planning efforts made by state and federal wildlife agencies within the geographical range of the species. Although the listing was vacated by judicial ruling in September 2015, concern for persistence of the species persists. These actions illustrate the uncertain legal status and future conservation challenges for Lesser Prairie-Chickens. Ecology and Conservation of Lesser Prairie-Chickens provides a compendium of data, analytical results, and synthesis generated among expert wildlife biologists, conservation biologists, and ornithologists. It thoroughly reviews the life history, genetics, and ecology of the species, and is ultimately directed toward developing and establishing appropriate conservation management strategies. It presents a detailed analysis of the issues and risks relative to conservation as well as an overview of potential conservation tools. It also addresses the challenges that natural resource managers continue to face in their current conservation efforts. While dealing with immediate and short-term issues in Lesser Prairie-Chicken conservation, this book is also a useful starting point for guiding future research, management, and conservation of the species. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series provides a definitive reference for researchers, managers, and policy makers as well as those with interests in environmental science, avian biology, game bird management, or Great Plains ecology.

This book demonstrates the social, historical, and environmental framework within which humans have developed a relationship with the forest and its resources. Starting from the biological basis that permits the existence of forests to the use of forest resources in a modern human context, this book summarizes the interaction between humans and forest ecosystems. Designed for readers from a broad range of disciplines and interests including those from environmental sciences, environmental economics, sociology, anthropology, biology, forestry and human ecology and other related disciplines, the book evokes interest in the development of an integrated approach towards forest ecosystems and natural resources in the context of sustainability.

In a world where habitats are constantly changing and the impact of anthropization on the environment is increasingly intense, interactions between human and wildlife are becoming more and more complex. Some species pose problems for human activities while many others need to be helped in order to continue to exist. This book follows the first volume called 'Problematic Wildlife', edited by F.M. Angelici and published by Springer in 2016, which has had considerable success with readers and critics. The volume includes 21 chapters divided into 7 parts devoted specific topics which are approached in a multidisciplinary way. There are both review chapters and specific cases, always bearing in mind the interest for an international audience. The book is useful both for scientists, wildlife specialists, conservationists, zoologists, ecologists, university students, nature managers, and for those who live in contact with wildlife and its problems, such as farmers, shepherds, hunters, urban planners, and staff of parks and nature reserves. Its ultimate goal is to offer scientific and pragmatic approaches to manage each categories of problematic species.

This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

India has 7,500 km of coastline with diverse habitats and rich biota. Coastal ecosystems, unfortunately, are experiencing wide range of pressures due to siltation, eutrophication, coastal development, aquaculture and climate change. Those species that adapt to these pressures will expand their living boundaries while others may fade away. Accordingly, the study of coastal biodiversity is of great concern globally and constitutes an important element of global change research. Gujarat has 1,600 km of coastline, reportedly with rich diversity of seaweeds. Previously published accounts on seaweed biodiversity were mainly in the form of checklists, the earliest among these being the checklist of Krishnamurthy and Joshi prepared in the early 1970s. The more recent checklists are based almost entirely on secondary information. The present book entitled Seaweeds of India - The Diversity and Distribution of Seaweeds of Gujarat Coast is a timely publication based wholly on primary data. Data were collected through extensive and systematic ? eld studies conducted by the authors during different seasons over a three year period. The authors collected nearly 200 species of seaweeds belonging to 100 genera of Chlorophyta, Phaeophyta and Rhodophyta. Twenty-four of the species are new to Gujarat coast and three are new to Indian waters. The book contains high-quality images of the different species in their existing habitats. Brief taxonomical descriptions, together with information on ecology, distribution, seasonality and abundance, are covered for each of the species.

San Francisco Bay is a shallow estuary surrounded by a large population center. The forces that built it began with plate tectonics and involved the collision of the Pacific and North American plates and the subduction of the Juan de Fuka plate. Changes in the climate resulting from the last ice age yielded lower and then higher sea levels. Human activity influenced the Bay. Gold mining during the California gold rush sent masses of slit into the Bay. Humans have also built several major cities and filled significant parts of the Bay. This book describes the natural history and evolution of the SF Bay Area over the last 50 million years through the present and into the future. Key selling features: Summarizes a complex geological, geographical and ecological history Reviews how the San Francisco Bay has changed and will likely change in the future Examines the different roles and various drivers of Bay ecosystem function Includes the role of humans - both first peoples and modern populations - on the Bay Explores San Francisco Bay as an example of general bay ecolgical and environmental issues

Phocid (or earless or true) seals are ecologically diverse, occupying habitats from the tropics to the poles in marine and freshwater and feeding on anything from tiny zooplankton to other marine mammals. There are 18 species of phocid seals, the smallest species (ringed seal) is more than 20 times smaller than the largest (southern elephant seal), with marked sexual dimorphism present in some species. This book examines the behavior, ecology, and physiology that allow phocid seals to inhabit such a wide range of habitats. The book is composed of 16 chapters written by 37 authors from 8 countries. The book first describes the general patterns of phocid behavior, followed by descriptions of what is known about well-studied species. We have taken a holistic approach, focusing not only on the behaviors themselves but also on the factors that constrain the expression of behavior and the proximate mechanisms driving behavior. In many cases, the chapters represent collaborations between well-established researchers and early-mid career individuals who bring new perspectives to help carry the field of phocid behavioral ecology well into the future.

This volume explores the diversity of distributed eyes and other unusual visual systems in nature.  It compares the unique themes of optics, neural processing, and behavioral control that emerge from these visual systems with more-canonical eyes. This volume attempts to answer a number of questions about distributed visual systems. What are distributed visual systems good for, how do they function, and why have they arisen independently in so many phyla? Why are eye designs and visual system arrangements much more diverse in invertebrates? Each chapter includes an overview of the visual systems that exist in their group of animals, relates vision to ecology, and takes a comparative approach. 

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.

Tidal freshwater forested wetlands are unique wetland systems. Occupying low relief coastal areas which are subject to both upland runoff and tidal flooding, these systems are especially vulnerable to pressure from human development and to climate change impacts of sea-level rise and increased drought/flood frequency. Yet to date the ecological dynamics, distribution, and conservation status of these communities is poorly understood.This book draws together the latest findings from investigators focusing on the hydrological processes, community organization, and stress physiology of freshwater, tidally influenced land-margin forests of the southeastern United States. It describes the land use history that led to the restricted distribution of these wetlands, and provides descriptions of the hydrology, soils, biogeochemistry, and physiological ecology of these systems, highlighting the similarities shared among tidal freshwater forested wetlands.

There is more to biological rhythms than circadian clocks. This book aims at promoting the exciting potential of a deeper understanding of circannual, circatidal, and circalunar clocks. It highlights new developments, summarizes existing knowledge, and integrates different perspectives with the tools and ideas of diverse fields of current biology. For predominantly pragmatic reasons, research in recent decades was mostly concerned with circadian clocks. Clocks on other timescales, however, have been largely neglected and therefore still appear "enigmatic". Thanks to the rapid development of methods in molecular biology as well as in ecology, we are now able to re-approach these clocks. Laboratories around the world are showing fresh interest and substantial progress is being made in many independent projects. The book's two sections address the moon-derived circatidal, circasemilunar, and lunar cycles on the one hand (10 chapters), and the sun-derived circannual cycles on the other (6 chapters). This work brings together authors with an expansive array of expertise and study systems, ranging from tidal cycles of marine invertebrates to annual cycles of birds and mammals, and from behavioral to genetic and epigenetic backgrounds. While great challenges remain to be mastered, the book aims at conveying the excitement of unraveling, broadly, the rhythms of life.

The Pacific Arctic region is experiencing rapid sea ice retreat, seawater warming, ocean acidification and biological response. Physical and biogeochemical modeling indicates the potential for step-function changes to the overall marine ecosystem. This synthesis book was coordinated within the Pacific Arctic Group, a network of international partners working in the Pacific Arctic. Chapter topics range from atmospheric and physical sciences to chemical processing and biological response to changing environmental conditions. Physical and biogeochemical modeling results highlight the need for data collection and interdisciplinary modeling activities to track and forecast the changing ecosystem of the Pacific Arctic with climate change.

It presents case studies from the most important mountainous areas like the Himalayas, Caucasus and South America covering the countries like Malaysia, Sri Lanka, India, Nepal, Pakistan, Kirghizia, Georgia, Russia,Turkey, Indonesia, Malaysia and the Americas. The book will serve as an invaluable resource source undergraduates, graduate students, and researchers.

This book will provide a comprehensive discussion of groundwater sustainability, including what it is, how its definition has changed over time, why traditional assessments of it are wrong, how assessments of it are ideally multidisciplinary efforts recognizing that policy is more controlling of outcomes than science, and why achieving it is difficult once pumping exceeds sustainable levels of pumping. The book will provide a nontechnical background of hydrogeology relevant to groundwater sustainability and present several case studies from around the United States and the world. The book has been designed to appeal to academics, students, and practitioners. Academics, particularly those just getting into the subject, will find the book a useful entry in terms of management concepts and political realities of attempting to achieve groundwater sustainability. It will also be useful to academics in that the book will include discussions on the history and development of groundwater sustainability and the practical aspects of aspiring to and achieving sustainable production. Although not a textbook, the book could be used as the basis for teaching a course or as a supplement to a hydrogeology or groundwater management class. Accordingly, the book will include questions and additional reading materials at the end of each chapter. This book will also be useful to practitioners through non-technical explanations of the sciences, discussions of the nuances of defining sustainability in aquifers, and the presentation of case studies where sustainable management has failed and succeeded.

This book focuses on the use of molecular tools to study small populations of rare and endangered mammals, and presents case studies that apply an evolutionary framework to address innovative questions in the emerging field of mammalian conservation genomics using a highly diverse set of novel molecular tools. Novel and more precise molecular technologies now allow experts in the field of mammology to interpret data in a more contextual and empirical fashion and to better describe the evolutionary and ecological processes that are responsible for the patterns they observe. The book also demonstrates how recent advances in genetic/genomic technologies have been applied to assess the impact of environmental/anthropogenic changes on the health of small populations of mammals. It examines a range of issues in the field of mammalian conservation genomics, such as the role that the genetic diversity of the immune system plays in disease protection and local adaptation; the use of noninvasive techniques and genomic banks as a resource for monitoring and restoring populations; the structuring of population by physical barriers; and genetic diversity. Further, by integrating research from a variety of areas - including population genetics, molecular ecology, systematics, and evolutionary and conservation biology - it enables readers to gain a deeper understanding of the conservation biology of mammals that are at increasing risk of extinction at local, regional and global scales. As such, it offers a unique resource for a broad readership interested in the conservation biology of mammals and conservation management strategies to better preserve biodiversity.

This book gives basic facts about litter decomposition studies, which are of guidance for scientists who start studies. Since the publication of the third edition, there has been quite a development not only in the field of litter decomposition but also in supporting branches of science, which are important for fruitful work on and understanding of decomposition of plant litter and sequestration of carbon. A consequence is that 'old established truths' are becoming outdated. New knowledge in the fields of phytochemistry and microbial ecology has given a new baseline for discussing the concepts 'litter decomposition' and 'carbon sequestration'. We can also see a rich literature on litter decomposition studies using roots and wood as substrates. These have given new insights in factors that regulate the decomposition rate and as regards roots their contribution to sequestered carbon in humus. Additional facts on the role of temperature vs the litters' chemical composition may in part change our view on effects of climate change. Further information on applications of the new analytical technique (13C-NMR) for determining organic-chemical compounds has allowed us to develop these parts. Focus is laid on needle litter of Scots pine as a model substrate as this species has been considerably more studied than other litter species. Also the boreal/northern temperate coniferous forest has in part been given this role. Still, new information may allow us to develop information about litter from further tree species.

This book focuses on the robustness analysis of high accuracy surface modeling method (HASM) to yield good performance of it. Understanding the sensitivity and uncertainty is important in model applications. The book aims to advance an integral framework for assessing model error that can demonstrate robustness across sets of possible controls, variable definitions, standard error, algorithm structure, and functional forms. It is an essential reference to the most promising numerical models. In areas where there is less certainty about models, but also high expectations of transparency, robustness analysis should aspire to be as broad as possible. This book also contains a chapter at the end featuring applications in climate simulation illustrating different implementations of HASM in surface modeling. The book is helpful for people involved in geographical information science, ecological informatics, geography, earth observation, and planetary surface modeling.

The book is oriented towards undergraduates science and engineering students; postgraduates and researchers pursuing the field of microbiology, biotechnology, chemical - biochemical engineering and pharmacy. Various applications of microorganisms have been covered broadly and have been appropriately reflected in depth in 12 different chapters. The book begins with an insight to the diverse niche of microorganisms which have been explored and exploited in development of various biotechnological products and green processes. Further, how these microorganisms have been genetically modified to improve the desired traits for achieving optimal production of microbially derived products is discussed in the second chapter. Major route of production of microbially derived products and processes is through fermentation technology and therefore due emphasis on different aspects of fermentation technology has been given in the subsequent chapter. The development and deployment of biopesticides and biofertilizers which find tremendous application have been separately discussed under agricultural applications. Application of microbes for the removal of pollutants, recovery of metals and oils has also been discussed under environmental applications. The role of microbial systems in development of fermented foods and beverages have also been discussed in Chapter 6. The application of microbes in production of commodity chemicals and fine chemicals has also been discussed in separate chapters. A chapter has been dedicated to the tremendous applications of microbially produced enzymes in different industrial sectors. Another unique facet of this book is explaining the different methods by which desired traits of microorganisms have been improved for their efficacious and economical exploitation in the industry. A chapter is dedicated to exploitation of microorganisms in development of vaccines for human and veterinary use. Finally, the last chapter discusses the role of immobilization in optimization of industrial processes and development of microbial biosensors for industrial applications. Thus, this book is a holistic approach providing information on the present applications of microorganisms.

Biology of Termites, a Modern Synthesis brings together the major advances in termite biology, phylogenetics, social evolution and biogeography. In this new volume, David Bignell, Yves Roisin and Nathan Lo have brought together leading experts on termite taxonomy, behaviour, genetics, caste differentiation, physiology, microbiology, mound architecture, biogeography and control. Very strong evolutionary and developmental themes run through the individual chapters, fed by new data streams from molecular sequencing, and for the first time it is possible to compare the social organisation of termites with that of the social Hymenoptera, focusing on caste determination, population genetics, cooperative behaviour, nest hygiene and symbioses with microorganisms. New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species.

This book highlights studies of differentiation problems of natural geosystems because of anthropogenic impact. The systematic methodology of comprehensive ecological assessment of anthropogenic impact on natural geosystems and their differentiations on the level of technogenic conditionality for ensuring rational environmental management and environmental protection are discussed. The practical importance of this book lies in the evidence-based recommendations and actions for conservation and quality management of the environment in order to decrease the degree of anthropogenic impact and in prevention of degradation processes. The book is useful to the researchers, industrial, scientific, and other organizations in establishing the purpose of the problem and solution to environmental protection and rational environmental management.

More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.
