This textbook provides an introduction to the mathematical models of population dynamics in mathematical biology. The focus of this book is on the biological meaning/translation of mathematical structures in mathematical models, rather than simply explaining mathematical details and literacies to analyze a model. In some recent usages of the mathematical model simply with computer numerical calculations, the model includes some inappropriate mathematical structure concerning the reasonability of modeling for the biological problem under investigation. For students and researchers who study or use mathematical models, it is important and helpful to understand what mathematical setup could be regarded as reasonable for the model with respect to the relation between the biological factors involved in the assumptions and the mathematical structure of the model. Topics covered in this book are; modeling with geometric progression, density effect in population dynamics, deriving continuous time models from discrete time models, basic modeling for birth-death stochastic processes, continuous time models, modeling interspecific reaction for the continuous time population dynamics model, competition and prey-predator dynamics, modeling for population dynamics with a heterogeneous structure of population, qualitative analysis on the discrete time dynamical system, necessary knowledge about fundamental mathematical theories to understand the dynamical nature of continuous time models. The book includes popular topics in ecology and mathematical biology, as well as classic theoretical topics. By understanding the biological meaning of modeling for simple models, readers will be able to derive a specific mathematical model for a biological problem by reasonable modeling. The contents of this book is made accessible for readers without strong Mathematical background.

This book presents some results on selected taxa in the Himalayan region (mainly Nepal), pinpoints the threats to their survival and suggests ways how to avoid their extinction. Most chapters are based on graduate research projects - relatively long-term field studies. The data presented here can be a good source of updated information on the subject and will prove to be a very useful reference in future studies of Himalayan biodiversity. They also tend to pinpoint the existing gaps in our knowledge of this region. All the chapters are based on recent trends of biodiversity and conservation vision, so the book can be a potential alternative to the existing relatively older books with outdated vision and information. Its main goal, however, is to disseminate the information about biodiversity conservation problems in the Himalayan region among the people in the developed world.

This contributory volume is a comprehensive collection on the mangrove forest eco-system and its ecology, the resources and potentials of mangroves, conservation efforts, mangrove eco-system services and threats to conservation. The book is an all-inclusive compilation on the status, conservation and future of mangroves. Mangroves are a unique ecosystem providing several ecosystem services. They are formed in the inter-tidal areas of large rivers and coastal islands. Mangroves thrives due to constant interaction with the terrestrial and marine ecosystem. These are the species dynamics, varying tidal amplitudes, plant succession, changing floral pattern of the channels of the estuary, the varying sediment transportation. There was 20% decline in mangrove forest area in the last 25 years due mainly to conversion and coastal development. Lengthy recovery periods required for the degraded mangrove forests. Hence there is an urgent need to take stock of the updated information on these mangroves at global level. It is of immense value to scientific community involved in teaching, research and extension activities related to mangrove conservation.

This book offers an in-depth description of different groups of microbes (i.e. bacteria, protozoa, fungi and viruses) that exist in the rumen microbial community, and offers an overview of rumen microbiology, the rumen microbial ecosystem of domesticated ruminants, and rumen microbial diversity. It provides the latest concepts on rumen microbiology for scholars, researchers and teachers of animal and veterinary sciences. With this goal in mind, throughout the text we focus on specific areas related to the biology and complex interactions of the microbes in rumen, integrating significant key issues in each respective area. We also discuss rumen manipulation with plant secondary metabolites, microbial feed additives, utilization of organic acids, selective inhibition of harmful rumen microbes, and 'omics' approaches to manipulating rumen microbial functions. A section on the exploration and exploitation of rumen microbes addresses topics including the current state of knowledge on rumen metagenomics, rumen: an underutilized niche for industrially important enzymes and ruminal fermentations to produce fuels. We next turn our attention to commercial applications of rumen microbial enzymes and to the molecular characterization of euryarcheal communities within an anaerobic digester. A section on intestinal disorders and rumen microbes covers acidosis in cattle, urea/ ammonia metabolism in the rumen and nitrate/ nitrite toxicity in ruminant diets. Last, the future prospects of rumen microbiology are examined, based on the latest developments in this area. In summary, the book offers a highly systematic collection of essential content on rumen microbiology.

Although the majority of the world's forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

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.

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

This book is about relevant recent research topics in understanding aquaculture for practical approaches; aquatic science, engineering, feed and nutrition, immunology and health are reviewed. The book includes information on why certain fish strains differ in disease resistance, all the current data on fish cell populations, the regulation of the response by factors, and the major histocompatibility complex are explained in detail. The book contains the chapters on nutrition, feed and feed additives, ecology, immunology, microbiology, toxicology, biochemistry, nanotechnology, pharmacology, and biotechnology, among other fields of basic and applied research. Over the past era, scientists have recognized the importance of nutrition in maintaining the health of humans and other animal species, including fish. Humans and other terrestrial animals were the focus of previous research on the links between nutrition, immune response, and disease resistance. However, attempts to conduct similar studies using fish have met with limited success in the last two decades due to a lack of understanding of the immune response in fish. In most facilities, the animals are kept at relatively high densities, causing stress and disease problems are the challenges that we face today and this book opens up the exciting new area of research to truly understand the relationship between fish genetics and immune reactivity. The aquatic immune system turns out to be a crucial reference as aquatic products are increasingly used as model systems for vertebrate immune systems. This book provides that the research students and scientists with a useful text on the latest knowledge of the aquatic feed and nutrition, immune system, cutting-edge technologies, draws everyone's attention to the practice of small-scale aquaculture and provides a guide on how to responsibly use the water ecosystem and the steps needed to develop, test and market fish vaccines. The chapters will serve as introductions to these fields and up-to-date reviews of recent research advances. This book is intended for a wide range of readers, including nutritionists, disease specialists, feed formulators, students, extension specialists, and farmers, as well as university teachers, graduates and doctoral students in zoology, physiology, aquaculture, and biology in general.

Ground vibration consideration is gaining significance with people's decreasing tolerance of vibration, introduction of new environmental legislations, increasing use of equipment sensitive to vibration, ageing of existing buildings and expanding construction sites to/near collapsible/liquefiable/thixotropic soil.
This volume bridges the gap that exists between rather limited provisions of engineering codes/standards and complex numerical analyses/small-scale tests.
The book contains descriptions of ground vibration measurements, predictions and control for engineers. Effects of most frequent sources of ground vibration arising from construction/demolition, traffic and machinery, ground wave amplification and attenuation as well as foundation kinematic and inertial interaction have been considered by simplified analyses aimed at ease and speed of use for major problems in ground vibration engineering. Comments on assumptions, limitations, and factors affecting the results are given. Case studies and examples worldwide are included to illustrate the accuracy and usefulness of simplified methods. A list of references is provided for further consideration, if desired.

Audience This work is of interest to geotechnical engineers, engineering geologists, earthquake engineers and students.

Extra material Microsoft Excel spreadsheets with the input data and results for the case studies and examples considered in this book are available at http: //extras.springer.com

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.

At a time of societal urgency surrounding ecological crises from depleted fisheries to mineral extraction and potential pathways towards environmental and ecological justice, this book re-examines ecologically unequal exchange (EUE) from a historical and comparative perspective. The theory of ecologically unequal exchange posits that core or northern consumption and capital accumulation is based on peripheral or southern environmental degradation and extraction. In other words, structures of social and environmental inequality between the Global North and Global South are founded in the extraction of materials from, as well as displacement of waste to, the South. This volume represents a set of tightly interlinked papers with the aim to assess ecologically unequal exchange and to move it forward. Chapters are organised into three main sections: theoretical foundations and critical reflections on ecologically unequal exchange; empirical research on mining, deforestation, fisheries, and the like; and strategies for responding to the adverse consequences associated with unequal ecological exchange. Scholars as well as advanced undergraduate and graduate students will benefit from the spirited re-evaluation and extension of ecologically unequal exchange theory, research, and praxis.

This edited collection explores the relationships between humans and nature at a time when the traditional sense of separation between human cultures and a natural wilderness is being eroded. The 'Anthropocene,' whose literal translation is the 'Age of Man,' is one way of marking these planetary changes to the Earth system. Global climate change and rising sea levels are two prominent examples of how nature can no longer be simply thought of as something outside and removed from humans (and vice versa). This collection applies the concepts of ecology and entanglement to address pressing political, social, and cultural issues surrounding human relationships with the nonhuman world in terms of 'working with nature.' It asks, are there more or less preferable ways of working with nature? What forms and practices might this work take and how do we distinguish between them? Is the idea of 'nature' even sufficient to approach such questions, or do we need to reconsider using the term nature in favour of terms such as environments, ecologies or the broad notion of the non-human world? How might we forge perspectives and enact practices which build resilience and community across species and spaces, constructing relationships with nonhumans which go beyond discourses of pollution, degradation and destruction? Bringing together a range of contributors from across multiple academic disciplines, activists and artists, this book examines how these questions might help us understand and assess the different ways in which humans transform, engage and interact with the nonhuman world.
