This book maps extreme temperature increase under dangerous climate change scenarios in Brazil and their impacts on four key sectors: agriculture, health, biodiversity and energy. The book draws on a careful review of the literature and climate projections, including relative risk estimates. This synthesis summarizes the state-of-the-art knowledge and provides decision-makers with risk analysis tools, to be incorporated in public planning policy, in order to understand climate events which may occur and which may have significant consequences.
Chaparral shrubland ecosystems are an iconic feature of the California landscape, and a highly biodiverse yet highly flammable backdrop to some of the fastest growing urban areas in the United States. Chaparral-type ecosystems are a common element of all of the world's Mediterranean-type climate regions - of which California is one - yet there is little public appreciation of the intrinsic value and the ecosystem services that these landscapes provide. Valuing Chaparral is a compendium of contributions from experts in chaparral ecology and management, with a focus on the human relationship with chaparral ecosystems. Chapters cover a wide variety of subjects, ranging from biodiversity to ecosystem services like water provision, erosion control, carbon sequestration and recreation; from the history of human interactions with chaparral to current education and conservation efforts; and from chaparral restoration and management to scenarios of the future under changing climate, land use, and human population. Valuing Chaparral will be of interest to resource managers, the research community, policy makers, and the public who live and work in the chaparral dominated landscapes of California and other Mediterranean-type climate regions.
"Biodiversity" refers to the variety of life. It is now agreed that there is a "biodiversity crisis", corresponding to extinction rates of species that may be 1000 times what is thought to be "normal". Biodiversity science has a higher profile than ever, with the new Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services involving more than 120 countries and 1000s of scientists. At the same time, the discipline is re-evaluating its foundations - including its philosophy and even core definitions. The value of biodiversity is being debated. In this context, the tree of life ("phylogeny") is emerging as an important way to look at biodiversity, with relevance cutting across current areas of concern - from the question of resilience within ecosystems, to conservation priorities for globally threatened species - while capturing the values of biodiversity that have been hard to quantify, including resilience and maintaining options for future generations. This increased appreciation of the importance of conserving "phylogenetic diversity", from microbial communities in the human gut to global threatened species, has inevitably resulted in an explosion of new indices, methods, and case studies. This book recognizes and responds to the timely opportunity for synthesis and sharing experiences in practical applications. The book recognizes that the challenge of finding a synthesis, and building shared concepts and a shared toolbox, requires both an appreciation of the past and a look into the future. Thus, the book is organized as a flow from history, concepts and philosophy, through to methods and tools, and followed by selected case studies. A positive vision and plan of action emerges from these chapters, that includes coping with inevitable uncertainties, effectively communicating the importance of this "evolutionary heritage" to the public and to policy-makers, and ultimately contributing to biodiversity conservation policy from local to global scales.
This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts

Endophytes are commonly known as microorganisms, mainly bacteria and fungi, which live inside plant tissues without inducing symptoms. Considering the long-lived trees, endophytes have a fundamental role in preparing their hosts to face extreme weather conditions, drought, heat, cold, and pathogen and herbivore attacks. The current knowledge clearly demonstrates the importance of endophytes in shaping the plant diversity in a forest. Endophytes have an important capacity for biocontrol of forest diseases. Considering endophyte diversity and the range of various compounds and enzymes they can produce, endophytes can be used for various biotechnological applications.
This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.
This book is the first to explore in detail the systematics and taxonomy of the digenean fauna of fish in Indian marine waters. It includes morphological descriptions of 648 species in 190 genera and 30 families. The figures from the original publications are enhanced and made more attractive. Each description is accompanied by information on hosts and distribution. Digenetic trematodes, usually known as Digeneans, are the most diverse group of metazoan parasites of marine fishes. They are parasitic flatworms (Phylum Platyhelminthes) with a complex life-cycle and as adults inhabit mainly the alimentary system and associated organs, but also occur in the blood, under the scales, in the body cavity and in the gall and urinary bladders. Keys to families, genera and species are provided, except for a few large and controversial genera, where morphological characters are insufficient for identification. Although there is extensive literature on Digeneans, it is scattered and largely in obscure local journals. Bringing together most of the primary literature on the subject, this book provides a primer for further study and a starting point for the use of modern molecular methods for the fauna of this region. Unique in its scope, it is a valuable resource for students, professional parasitologists and ecologists as well as fishery and wildlife biologists.
This book presents valuable and recent lessons learned regarding the links between natural resources management, from a Socio-Ecological perspective, and the biodiversity conservation in Mexico. It address the political and social aspects, as well as the biological and ecological factors, involved in natural resources management and their impacts on biodiversity conservation. It is a useful resource for researchers and professionals around the globe, but especially those in Latin American countries, which are grappling with the same Bio-Cultural heritage conservation issues.
Igapo forests are a common part of the Amazon whose ecosystems are critical to our shared human future. The introduction addresses the structure, function and dynamics of igapo forests in the Amazon basin, focusing on their uniqueness due to their high level of complexity defined as the many ways that different components of igapo forests in the Amazon basin ecosystem interact and also on how those interactions are on a higher-order compared to other tropical forests. The text then breaks down the igapo ecosystem using these sections: (1) Igapo forests over space and time, (2) Water, light and soils, (3) The carbon cycle, (4) Litter, fungi and invertebrates, (5) Vertebrates, (6) Plant population studies, (7) Plant community studies, and (8) Human impacts and management. Experts from around the world serve as chapter authors that review what is known about their specific part of the igapo ecosystem, what research they have done, and also what needs to be done in the future.
The aim of this first book is to introduce the readers of the series to why Cuatro Cienegas Basin (CCB) is so unique, starting with the reason why astrobiologists became interested in this oasis in the first place; namely, the high diversity and abundance of stromatolites and microbial mats in continental waters to be found in the desert oasis. As NASA has long since discovered, the basin may offer the best analog of early Earth. In essence, CCB is a time machine that can take us far back and forth in time. In the respective chapters, the contributing authors explain the extraordinary microbial diversity of Cuatro Cienegas Basin from various perspectives. In order to do so, they explain their journey as well as the different tools used to unravel the basin's mysteries, such as: Why are there so many species in a place without food? How has life there survived the enormity of tectonic shifts through the ages, maintaining its ancient marine heritage?
This volume focuses on the ethnobiology of southern Chile's Archipelago of Chiloe. Chiloe presents a unique perspective on the intersection of society and biology owing to its vast natural resources, historic culture of cooperation, geographic isolation, and external resource exploitation. Contributions to this volume cover knowledge bases in both marine and terrestrial systems, and how specific local knowledge types contributed to a variety of strategies, including subsistence, social-ecological resilience, resource conservation, cultural heritage preservation, economic systems, and mitigating uncertainty. This book addresses the specificities of human-environment interaction on a resource-rich island, and how historic knowledge and practices can help configure adaptation to a changing social-ecological landscape.
This study, based on a literature review and simulations, shows the efficiency of cover crops at catching nitrate in most agriculture situations. It also analyzes both the negative impacts they can have and the ecosystem services they can provide. The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the drainage water. This study allows quantifying the efficiency of cover crops at catching nitrate and optimizing their implantation conditions over a large range of French pedoclimatic conditions. The presence of high nitrate levels in surface and ground waters, due to excessive nitrogen fertilization and natural production of nitrate by soil organic matter mineralization, is a double challenge for public health and environment protection.
This volume focuses on small mammal fossils from extinct Asian faunas of about 1 to 7 million years ago in North China. These played a role in the emergence of vertebrate paleontology as a modern science in that country. This second volume of the sub-series Late Cenozoic Yushe Basin, Shanxi Province, China: Geology and Fossil Mammals in the Vertebrate Paleobiology and Paleoanthropology book series deals with a rich microfauna fossil record; megafauna follow in subsequent volumes. This research on Yushe Basin fossils provides a view of changes in northeast Asian terrestrial faunas during the Late Neogene, and therefore is a key to the biochronology for a vast part of the continent. The faunas recovered by the multinational team working in this region represent changes in small mammal communities of the Yushe Basin, revealed on a finer time scale that has not been achieved previously. Detailed systematic studies on small mammal groups proceeded under the care of specialists are outlined in the chapters of this volume. Paleontologists, ecologists and evolutionary biologists will find this book appealing.
This book offers a unique perspective on Zionism. The author, a geneticist by training, focuses on science, rather than history. He looks at the claims that Jews constitute a people with common biological roots. An argument that helps provide justification for the aspirations of this political movement dedicated to the return of the Jewish people to their homeland. His study explores two issues. The first considers the assertion that there is a biology of the Jews. The second deals with attempts to integrate this idea into a consistent history. Both issues unfolded against the background of a romantic national culture of Western Europe in the 19th century: Jews, primarily from Eastern Europe, began to believe these notions and soon they took the lead in the re-formulation of Jewish and Zionist existence. The author does not intend to present a comprehensive picture of the biological literature of the origins of a people and the blood relations between them. He also recognizes that the subject is emotionally-loaded. The book does, however, present a profound mediation on three overlapping questions: What is special or unique to the Jews? Who were the genuine Jews? And how can one identify Jews? This volume is a revised and edited English version of Tzionut Vehabiologia shel Hayehudim, published in 2006.
This book examines the long-term fate of invasive species by detailing examples of invaders from different zoological and botanical taxa from various places around the world. Readers will discover what happened, after a century or so, to 'classical' invaders like rabbits in Australia, house sparrows in North America, minks in Europe and water hyacinths in Africa and Asia. Chapters presented in the book focus on eighteen species in the form of in-depth case studies including: earthworms, zebra mussels, Canadian water weed, Himalayan balsam, house sparrows, rabbits, crayfish plague, Colorado beetles, water hyacinths, starlings, Argentine ant, Dutch elm disease, American mink, cane toad, raccoons, Canadian beavers, African killer bees and warty comb jelly. Invaded areas described are in Africa, Asia, Australia, Europe, North America, Pacific islands, and South America. Readers will get some ideas about the likely future of current invaders from the fate of old ones. This book is intended for undergraduates studying environmental sciences, researchers and members of environmental NGO's.
This book places lion conservation and the relationship between people and lions both in historical context and in the context of the contemporary politics of conservation in Africa. The killing of Cecil the Lion in July 2015 brought such issues to the public's attention. Were lions threatened in the wild and what was the best form of conservation? How best can lions be saved from extinction in the wild in Africa amid rural poverty, precarious livelihoods for local communities and an expanding human population? This book traces man's relationship with lions through history, from hominids, to the Romans, through colonial occupation and independence, to the present day. It concludes with an examination of the current crisis of conservation and the conflict between Western animal welfare concepts and sustainable development, thrown into sharp focus by the killing of Cecil the lion. Through this historical account, Keith Somerville provides a coherent, evidence-based assessment of current human-lion relations, providing context to the present situation. This book will be of interest to students and scholars of environmental and African history, wildlife conservation, environmental management and political ecology, as well as the general reader.
Divided into three sections, this book explores the three main pillars of sustainable development, namely economy, environment and society, and their interlinkages at the regional level. The first section, Access and Benefit Sharing (ABS) for sustainable development, focuses on international agreements and national legislation, as well as the challenges in implementing ABS in e.g. India. In turn, the second section examines the process of forming Biodiversity Management Committees (BMCs) at the Local Self Government (LSG) level to promote environmental sustainability, highlighting local and community-level conservation initiatives that have led to the conservation of habitats and species. The third section addresses poverty eradication and food security. The case studies included demonstrate how the combination of traditional knowledge and modern techniques can enhance the productivity of traditional crop varieties, yielding greater benefits for communities. The aim of this volume is to disseminate the lessons learned from these case studies, as well as the findings from projects already in place, which can offer recommendations that can be applied to similar problems elsewhere in an attempt to find environmental solutions for sustainable development. Further, it introduces readers to new approaches to inclusive development, demonstrating that participation and grass root empowerment are key drivers of equitable and sustainable development.
With one volume each year, this series keeps scientists and advanced students informed of the latest developments and results in all areas of the plant sciences. The present volume includes reviews on plant physiology, biochemistry, ecology, and ecosystems.
This book discusses several recent theoretic advancements in interdisciplinary and transdisciplinary integration in the field of evolution. While exploring novel views, the text maintains a close link with one of the most broadly held views on evolution, namely that of "Darwinian evolution." This work puts forth a new point of view which allows researchers to define in detail the concept of evolution. To create this conceptual definition, the text applies a stringent object-based focus. With this focus, the editor has been able to develop an object-based pattern of evolution at the smallest scale. Subsequently, this smallest scale pattern is used as an innovative basis for generalizations. These generalizations create links between biological Darwinism and generalized Darwinism. The object-based approach that was used to suggest innovations in the field of Darwinian evolution also allowed for contributions to other topics, such as major evolutionary transitions theory, the definition of life and the relationships between evolution, self-organization and thermodynamics. Together, the chapters of this book and the multidisciplinary reflections and comments of various specialists on these chapters offer an exciting palette of innovative ideas.
This book critically reviews advances in our understanding of the biology of vascular epiphytes since Andreas Schimper's 1888 seminal work. It addresses all aspects of their biology, from anatomy and physiology to ecology and evolution, in the context of general biological principles. By comparing epiphytes with non-epiphytes throughout, it offers a valuable resource for researchers in plant sciences and related disciplines. A particular strength is the identification of research areas that have not received the attention they deserve, with conservation being a case in point. Scientists have tended to study pristine systems, but global developments call for information on epiphytes in human-disturbed systems and the response of epiphytes to global climate change.

Pflanzen und ihre Lebensraume - Wie konnen Pflanzen unter speziellen Lebensbedingungen gedeihen, wachsen und sich vermehren? Organismen interagieren mit ihrer Umwelt auf verschiedenen Ebenen. Die fundamentale Einheit geobotanischer Untersuchungen ist der individuelle pflanzliche und mikrobielle Organismus. Seine evolutive Entwicklung ist das Ergebnis eines selektiven Prozesses und seiner Einnischung in spezifische Lebensraume auf einem hoheren Organisationsniveau, den Populationen, den Pflanzengesellschaften und den von ihnen aufgebauten Okosystemen. Die Beziehungsgeflechte von Klima, Boden und biotischen Interaktionen werden dargestellt. Zahlreiche Beispiele erlautern die Gesetzmassigkeiten. Die Autoren zeigen, wie naturliche Prozesse, beispielsweise Verlandungen von Gewassern, funktionieren, Sukzessionen sich auswirken oder auch wie sich Storungen nach Sturmen, Branden oder Klimaanderungen zeigen. Eine Einfuhrung in komplexe Okosysteme."
Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem. |
