This book identifies all valid species belonging to the superfamily Mactroidea living in American waters, distributed across fourteen biogeographical provinces. It also provides an updated classification of the widely occurring Mactroidea superfamily, which comprises eight subfamilies grouped into four families: Mactridae (Lamarck, 1809); Anatinellidae (Deshayes, J.Gray 1853); Cardiliidae (Fischer, 1887) and Mesodesmatidae (J. Gray, 1840). The species included in this superfamily are known to have existed in North America since the Early Cretaceous.

Very Short Introductions: Brilliant, Sharp, Inspiring Extinction is a natural process. In geological time there have been several periods of mass extinction. One of these periods is unfolding right now but all the evidence suggests that current extinction rates are between a hundred and a thousand times greater than the background rate. To put this in to context, a quarter of all known mammalian species is at risk. The current extinction crisis is unique, because it is caused by the impact of one species, humans, on all others. This acceleration of species loss, and the much more widespread reductions in the populations of many species, is not merely a tragedy in aesthetics, it is also a threat to the quality of human life, indeed to the entire human enterprise. Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists - it is the lifeline business of everybody. In this Very Short Introduction, David Macdonald introduces the concept of biodiversity and the basic biological processes that it involves - evolutionary, ecological, and behavioral. He considers the various threats to biodiversity, their impacts, and some of the solutions to the problems; concluding by considering the future of biodiversity conservation. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Population genomics has provided unprecedented opportunities to unravel the mysteries of marine organisms in the oceans' depths. The world's oceans, which make up 70% of our planet, encompass diverse habitats and host numerous unexplored populations and species. Population genomics studies of marine organisms are rapidly emerging and have the potential to transform our understanding of marine populations, species, and ecosystems, providing insights into how these organisms are evolving and how they respond to different stimuli and environments. This knowledge is critical for understanding the fundamental aspects of marine life, how marine organisms will respond to environmental changes, and how we can better protect and preserve marine biodiversity and resources. This book brings together leading experts in the field to address critical aspects of fundamental and applied research in marine species and share their research and insights crucial for understanding marine ecosystem diversity and function. It also discusses the challenges, opportunities and future perspectives of marine population genomics.

This volume comprehensively reviews recent advances in our understanding of the diversity of microbes in various types of terrestrial ecosystems, such as caves, deserts and cultivated fields. It is written by leading experts, and highlights the culturable microbes identified using conventional approaches, as well as non-culturable ones unveiled with metagenomic and microbiomic approaches. It discusses the role of microbes in ecosystem sustainability and their potential biotechnological applications. The book further discusses the diversity and utility of ectomycorrhizal and entomopathogenic fungi and yeasts that dwell on grapes, it examines the biotechnological applications of specific microbes such as lichens, xylan- and cellulose-saccharifying bacteria and archaea, chitinolytic bacteria, methanogenic archaea and pathogenic yeasts.

This Open Access volume aims to methodologically improve our understanding of biodiversity by linking disciplines that incorporate remote sensing, and uniting data and perspectives in the fields of biology, landscape ecology, and geography. The book provides a framework for how biodiversity can be detected and evaluated-focusing particularly on plants-using proximal and remotely sensed hyperspectral data and other tools such as LiDAR. The volume, whose chapters bring together a large cross-section of the biodiversity community engaged in these methods, attempts to establish a common language across disciplines for understanding and implementing remote sensing of biodiversity across scales. The first part of the book offers a potential basis for remote detection of biodiversity. An overview of the nature of biodiversity is described, along with ways for determining traits of plant biodiversity through spectral analyses across spatial scales and linking spectral data to the tree of life. The second part details what can be detected spectrally and remotely. Specific instrumentation and technologies are described, as well as the technical challenges of detection and data synthesis, collection and processing. The third part discusses spatial resolution and integration across scales and ends with a vision for developing a global biodiversity monitoring system. Topics include spectral and functional variation across habitats and biomes, biodiversity variables for global scale assessment, and the prospects and pitfalls in remote sensing of biodiversity at the global scale.

Evolutionary developmental biology or evo-devo is a field of biological research that compares the underlying mechanisms of developmental processes in different organisms to infer the ancestral condition of these processes and elucidate how they have evolved. It addresses questions about the developmental bases of evolutionary changes and evolution of developmental processes. The book's content is divided into three parts, the first of which discusses the theoretical background of evo-devo. The second part highlights new and emerging model organisms in the evo-devo field, while the third and last part explores the evo-devo approach in a broad comparative context. To the best of our knowledge, no other book combines these three evo-devo aspects: theoretical considerations, a comprehensive list of emerging model species, and comparative analyses of developmental processes. Given its scope, the book will offer readers a new perspective on the natural diversity of processes at work in cells and during the development of various animal groups, and expand the horizons of seasoned and young researchers alike.

Meeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases fertility. As such, measures are required to restore the soil health and productivity: organic matter, beneficial microorganisms and nutrient dynamics can all improve the physical, chemical and biological properties of soil. Understanding the role of soil health restoration and management in sustainability and nutritional security calls for a holistic approach to assess soil functions and examine the contributions of a particular management system within a defined timescale. Further, best management practices in cropping systems are important in ensuring sustainability and food and nutritional security without compromising the soil quality and productivity po tential. Rational soil management practices must allow environmentally and economically sustain able yields and restoration of soil health.

This open access book contains 13 contributions on global animal law, preceded by an introduction which explains key concepts and methods. Global Animal Law refers to the sum of legal rules and principles (both state-made and non-state-made) governing the interaction between humans and other animals, on a domestic, local, regional, and international level. Global animal law is the response to the mismatch between almost exclusively national animal-related legislation on the one hand, and the global dimension of the animal issue on the other hand. The chapters lay some historical foundations in the ius naturae et gentium, examine various aspects of how national and international law traditionally deals with animals as commodity; and finally suggest new legal concepts and protective strategies. The book shows numerous entry points for animal issues in international law and at the same time shifts the focus and scope of inquiry.

This book discusses microbial diversity in various habitats and environments, its role in ecosystem maintenance, and its potential applications (e.g. biofertilizers, biocatalysts, antibiotics, other bioactive compounds, exopolysaccharides etc.). The respective chapters, all contributed by renowned experts, offer cutting-edge information in the fields of microbial ecology and biogeography. The book explains the reasons behind the occurrence of various biogeographies and highlights recent tools (e.g. metagenomics) that can aid in biogeography studies by providing information on nucleic acid sequence data, thereby directly identifying microorganisms in various habitats and environments. In turn, the book describes how human intervention results in depletion of biodiversity, and how numerous hotspots are now losing their endemic biodiversity, resulting in the loss of many ecologically important microorganisms. In closing, the book underscores the importance of microbial diversity for sustainable ecosystems.

This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.

Since the first edition of this book published in 2005, there has been an immense amount of new and fascinating work on the history, ecology, and evolution of the Mediterranean flora. During this time, human impacts have continued to increase dramatically, significantly influencing both the ecology and evolution of the region's biota. This timely and comprehensive update of the original text integrates a diverse and scattered literature to produce a synthetic account of Mediterranean plant evolutionary ecology. It maintains the accessible style of its previous version whilst incorporating recent work in a new structural framework. This is not a traditional "plant science" book per se, but a novel integration of history, ecology, biogeography, and evolution, all set in the context of a dramatically increasing human footprint. There is a particular emphasis on the role of human activities as an ecological factor and their subsequent impact on plant evolution. Conversely, it demonstrates how an understanding of the evolutionary ecology of the region's flora can be used to provide insights into its future conservation and management. Plant Evolution in the Mediterranean is aimed at all those who are interested in the biology of the Mediterranean region, whether it is taxonomy, ecology, evolution, conservation policy and management, or the regional history of its biodiversity in general. It will be of relevance and use to all graduate students and researchers of Mediterranean-type ecosystem ecology and geography, as well as professional ecologists, evolutionary biologists, conservation biologists, and environmental practitioners requiring a concise, authoritative overview of the topic.

The Amazon is a land of superlatives. The complex ecosystem covers an area about the size of the continental U.S. The Amazon River discharges 57 million gallons of water per second-in two hours, this would be enough to supply all of New York City's 7.5 million residents with water for a year. Its flora and fauna are abundant. Approximately one of every four flowering plant species on earth resides in the Amazon. A single Amazonian river may contain more fish species than all the rivers in Europe combined. It is home to the world's largest anteater, armadillo, freshwater turtle, and spider, as well as the largest rodent (which weighs over 200 lbs.), catfish (250 lbs.), and alligator (more than half a ton). The rainforest, which contains approximately 390 billion trees, plays a vital role in stabilizing the global climate by absorbing massive amounts of carbon dioxide-or releasing it into the atmosphere if the trees are destroyed. Severe droughts in both Brazil and Southeast Asia have been linked to Amazonian deforestation, as have changing rainfall patterns in the U.S., Europe, and China. The Amazon also serves as home to millions of people. Approximately seventy tribes of isolated and uncontacted people are concentrated in the western Amazon, completely dependent on the land and river. These isolated groups have been described as the most marginalized peoples in the western hemisphere, with no voice in the decisions made about their futures and the fate of their forests. In this addition to the What Everyone Needs to Know (R) series, ecologist and conservation expert, Mark J. Plotkin, who has spent 40 years studying Amazonia, its peoples, flora, and fauna. The Amazon offers an engaging overview of this irreplaceable ecosystem and the challenges it faces.

Several textbooks and edited volumes are currently available on general soil fertility but' to date' none have been dedicated to the study of "Sustainable Carbon and Nitrogen Cycling in Soil." Yet this aspect is extremely important, considering the fact that the soil, as the 'epidermis of the Earth' (geodermis)' is a major component of the terrestrial biosphere. This book addresses virtually every aspect of C and N cycling, including: general concepts on the diversity of microorganisms and management practices for soil, the function of soil's structure-function-ecosystem, the evolving role of C and N, cutting-edge methods used in soil microbial ecological studies, rhizosphere microflora, the role of organic matter (OM) in agricultural productivity, C and N transformation in soil, biological nitrogen fixation (BNF) and its genetics, plant-growth-promoting rhizobacteria (PGPRs), PGPRs and their role in sustainable agriculture, organic agriculture, etc. The book's main objectives are: (1) to explain in detail the role of C and N cycling in sustaining agricultural productivity and its importance to sustainable soil management; (2) to show readers how to restore soil health with C and N; and (3) to help them understand the matching of C and N cycling rules from a climatic perspective. Given its scope, the book offers a valuable resource for educators, researchers, and policymakers, as well as undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and the environmental sciences. Gathering cutting-edge contributions from internationally respected researchers, it offers authoritative content on a broad range of topics, which is supplemented by a wealth of data, tables, figures, and photographs. Moreover, it provides a roadmap for sustainable approaches to food and nutritional security, and to soil sustainability in agricultural systems, based on C and N cycling in soil systems.

It includes case studies and reviews on organic agriculture, horticulture and pest management, use of microorganisms, composting, crop rotation, organic milk and meat production, as well as ecological issues. This unique book addresses a wide array of topics from all continents, making it a valuable reference resource for students, researchers and agriculturists who are concerned with biodiversity, agroecology and sustainable development of agricultural resources.

This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

This book examines theories and ethnographies related to the anthropology of power in conservation. Conservation thought and practice is power laden-conservation thought is powerfully shaped by the history of ideas of nature and its relation to people, and conservation interventions govern and affect peoples and ecologies. This book argues that being able to think deeply, particularly about power, improves conservation policy-making and practice. Political ecology is by far the most well-known and well-published approach to thinking about power in conservation. This book analyzes the relatively neglected but robust anthropology of conservation literature on politics and power outside political ecology, especially literature rooted in Foucault. It is intended to make four of Foucault's concepts of power accessible, concepts that are most used in the anthropology of conservation: the power of discourses, discipline and governmentality, subject formation, and neoliberal governmentality. The important ethnographic literature that these concepts have stimulated is also examined. Together, theory and ethnography underpin our emerging understanding of a new, Anthropocene-shaped world. This book will be of great interest to students and scholars of conservation, environmental anthropology, and political ecology, as well as conservation practitioners and policy-makers.

"Diagnostics in Plant Breeding" is systematically organizing cutting-edge research reviews on the development and application of molecular tools for the prediction of plant performance. Given its significance for mankind and the available research resources, medical sciences are leading the area of molecular diagnostics, where DNA-based risk assessments for various diseases and biomarkers to determine their onset become increasingly available. So far, most research in plant genomics has been directed towards understanding the molecular basis of biological processes or phenotypic traits. From a plant breeding perspective, however, the main interest is in predicting optimal genotypes based on molecular information for more time- and cost-efficient breeding schemes. It is anticipated that progress in plant genomics and in particular sequence technology made recently will shift the focus from "explanatory" to "predictive" in crop science. This book assembles chapters on all areas relevant to development and application of predictive molecular tools in plant breeding by leading authorties in the respective areas.

This book provides the first contemporary assessment of area-based conservation and its implications for nature and society. Now covering 15 per cent of the land surface and a growing area of ocean, the creation of protected areas is one of the fastest conscious changes in land management in history. But this has come at a cost, including a backlash from human rights organisations about the social impacts of protected areas. At the same time, a range of new types of area-based conservation has emerged, based on indigenous people's territories, local community lands and a new designation of "other effective area-based conservation measures". This book provides a concise overview of the status and possible futures of area-based conservation. With many people calling for half the earth's land surface to remain in a natural condition, this book taps into the urgent debate about the feasibility of such an aim and the ways in which such land might be managed. It provides a timely contribution by people who have been at the centre of the debate for the last twenty years. Building on the authors' large personal knowledge, the book draws on global case studies where the authors have firsthand experience, including Yosemite National Park (USA), Blue Mountains National Park (Australia), Bwindi National Park (Uganda), Chingaza National Park (Colombia), Ustyart Plateau (Kazakhstan), Snowdonia National Park (Wales) and many more. This book is essential reading for students, academics and practitioners interested in conservation and its impact on society.

Natural resource management by rural citizens in tropical regions is crucial both to the conservation of biodiversity and ecosystem processes, but also to the the well-being and food security of the people that live there. This situation is especially acute in Africa where conflicts between habitat destruction and utilization can arise in areas which are important not only for biodiversity but for the long-term maintenance of ecosystems on which the people ultimately rely. There can also be conflicts between outside specialists and the indigenous knowledge of local communities. A holistic approach involving local peoples in management of their natural resources is therefore essential. A range of approaches to the problem is explored here in relation to natural resource management to local development and livelihoods, and the multi-functional nature of land-use. Major topics debated are the dichotomy between strictly protected areas and ones including human activity, people-centred rather than legally enforced conservation, market forces, and the interrelationships between agriculture and conservation. The book has 12 chapters, prepared by researchers actively involved in community aspects of natural resource management in Africa, and is based on an international workshop held in Niamey, Niger, in 2008. It will be of interest to all involved in the community approach to biodiversity conservation in less developed countries generally and not only in Africa as many of the issues addressed are pertinent globally. Reprinted from Biodiversity and Conservation 18: 10 (2009).

The habitats of most species have been fragmented by human actions, isolating small populations that consequently develop genetic problems. Millions of small, isolated, fragmented populations are likely suffering from inbreeding depression and loss of genetic diversity, greatly increasing their risk of extinction. Crossing between populations is required to reverse these effects, but managers rarely do so. A key reason for such inaction is that managers are often advised to manage populations in isolation whenever molecular genetic methods indicate genetic differences among them. Following this advice will often doom small populations to extinction when the habitat fragmentation and genetic differences were caused by human activities. A paradigm shift is required whereby evidence of genetic differentiation among populations is a trigger to ask whether any populations are suffering genetic problems, and if so, whether they can be rescued by augmenting gene flow. Consequently, there is now an urgent need for an authoritative practical guide to facilitate this paradigm shift in genetic management of fragmented populations.

Based on graph theory studies this book seeks to understand how tropical species interact with each other and how these interactions are affected by perturbations in some of the most species-rich habitats on earth. Due to the great diversity of species and interactions in the tropics, this book addresses a wide range of current and future issues with empirical examples and complete revisions on different types of ecological networks: from mutualisms to antagonisms. The goal of this publication is not to be only for researchers but also for undergraduates in different areas of knowledge, and also to serve as a reference text for graduate-level courses mainly in the life sciences.
