Ecosystems are complex and enigmatic entities that are ultimately our life support systems. Understanding these systems to the point of being able to predict their behaviour in the face of perturbations requires that researchers adopt a number of strategies that vary in both approach and scale. This book, in a sense, is representative of some of the developments that have unfolded when math and physics met ecology. Here, some of the world s leading ecologists examine ecosystems from theoretical, experimental, and empirical viewpoints, from energetics to ecosystems. The book begins with simplifying and synthesizing nature s complex relationships. It then moves on to explore the mapping between food web structure and function and ends with the role of theory in integrating different research areas. From the breadth of systems analyzed to the rigor of approaches taken, this book is not only a useful resource for students and researchers in ecology, but serves as a fitting tribute to the life and work of Peter Yodzis."
Biological Diversity provides an up to date, authoritative review of the methods of measuring and assessing biological diversity, together with their application. The book's emphasis is on quantifying the variety, abundance, and occurrence of taxa, and on providing objective and clear guidance for both scientists and managers. This is a fast-moving field and one that is the focus of intense research interest. However the rapid development of new methods, the inconsistent and sometimes confusing application of old ones, and the lack of consensus in the literature about the best approach, means that there is a real need for a current synthesis. Biological Diversity covers fundamental measurement issues such as sampling, re-examines familiar diversity metrics (including species richness, diversity statistics, and estimates of spatial and temporal turnover), discusses species abundance distributions and how best to fit them, explores species occurrence and the spatial structure of biodiversity, and investigates alternative approaches used to assess trait, phylogenetic, and genetic diversity. The final section of the book turns to a selection of contemporary challenges such as measuring microbial diversity, evaluating the impact of disturbance, assessing biodiversity in managed landscapes, measuring diversity in the imperfect fossil record, and using species density estimates in management and conservation.
Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.
In May 2004, the Alexander Koenig Zoological Research Museum hosted the Fifth International Symposium on Tropical Biology. This series was established at the ZFMK in the early 1980s, and has variably focused on systematics and ecology of tropical organisms, with an emphasis on Africa. Previous volumes are those edited by Schuchmann (1985), Peters and Hutterer (1990), Ulrich (1997), and Rheinwald (2000). The symposium in 2004 was organized by the Entomology Department under the direction of Michael Schmitt. The intention was to focus on Africa rather than on a particular taxon, and to highlight biodiversity at all levels ranging from molecules to ecosystems. This focus was timely partly because of the currently running BIOTA Africa programmes (BIOdiversity Monitoring Transect Analysis in Africa). BIOTA is an interdisciplinary research project focusing on sustainable use and conservation of biodiversity in Africa (http: //www.biote-africa.de). Session titles were Biogeography and Speciation Processes, Phylogenetic Patterns and Systematics, Diversity Declines and Conservation, and Applied Biodiversity Informatics. Each session was opened by an invited speaker, and all together 77 lectures and 59 posters were presented. There were over 200 participants and it was gratifying to us to meet colleagues from 26 nations, including Russia, Ukraine, Japan, USA, and ten African countries. We thank all participants for their valuable contributions
This work synthesizes the current state of knowledge on the biology of polar benthic marine algae and presents an outlook on their responses to changing environmental conditions in polar regions. Topics treated include environment, biodiversity and biogeography of micro- and macroalgae, including an update of the knowledge of the red algal flora of Antarctica. It treats the chemical ecology as well as the primary production and ecophysiology of polar benthic algae with new information on the important contribution of benthic microalgae to the productivity in costal areas.
Increasing evidence suggests that the composition and spatial configuration - the pattern - of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales. This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture. An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.
This issue of Journal of Insect Conservation is the first to be dedicated entirely to beetles. It contains a number of papers to demonstrate the variety and scope of problems and conservation concerns that surround these insects. A short introductory perspective is followed by eight original contributions, in which beetles from many parts of the world are considered, and in which some major threats to their wellbeing are evaluated.
A series of original papers and reviews dealing with the peculiarities of island insects and their conservation in many parts of the world. Contributions to this special issue of Journal of Insect Conservation range from biogeographical analyses and ecological features of island insects and their evolution to the variety of concerns for their wellbeing, and practical conservation through a variety of, sometimes novel, approaches. They provide a valuable and up-to-date resource for entomologists and conservation practitioners.
The major subdisciplines of ecology--population ecology, community ecology, ecosystem ecology, and evolutionary ecology--have diverged increasingly in recent decades. What is critically needed today is an integrated, real-world approach to ecology that reflects the interdependency of biodiversity and ecosystem functioning. "From Populations to Ecosystems" proposes an innovative theoretical synthesis that will enable us to advance our fundamental understanding of ecological systems and help us to respond to today's emerging global ecological crisis. Michel Loreau begins by explaining how the principles of population dynamics and ecosystem functioning can be merged. He then addresses key issues in the study of biodiversity and ecosystems, such as functional complementarity, food webs, stability and complexity, material cycling, and metacommunities. Loreau describes the most recent theoretical advances that link the properties of individual populations to the aggregate properties of communities, and the properties of functional groups or trophic levels to the functioning of whole ecosystems, placing special emphasis on the relationship between biodiversity and ecosystem functioning. Finally, he turns his attention to the controversial issue of the evolution of entire ecosystems and their properties, laying the theoretical foundations for a genuine evolutionary ecosystem ecology. "From Populations to Ecosystems" points the way to a much-needed synthesis in ecology, one that offers a fuller understanding of ecosystem processes in the natural world.
Leading paleontologist J. David Archibald explores the rich history of visual metaphors for biological order from ancient times to the present and their influence on humans' perception of their place in nature, offering uncommon insight into how we went from standing on the top rung of the biological ladder to embodying just one tiny twig on the tree of life. He begins with the ancient but still misguided use of ladders to show biological order, moving then to the use of trees to represent seasonal life cycles and genealogies by the Romans. The early Christian Church then appropriated trees to represent biblical genealogies. The late eighteenth century saw the tree reclaimed to visualize relationships in the natural world, sometimes with a creationist view, but in other instances suggesting evolution. Charles Darwin's On the Origin of Species (1859) exorcised the exclusively creationist view of the "tree of life," and his ideas sparked an explosion of trees, mostly by younger acolytes in Europe. Although Darwin's influence waned in the early twentieth century, by midcentury his ideas held sway once again in time for another and even greater explosion of tree building, generated by the development of new theories on how to assemble trees, the birth of powerful computing, and the emergence of molecular technology. Throughout Archibald's far-reaching study, and with the use of many figures, the evolution of "tree of life" iconography becomes entwined with our changing perception of the world and ourselves.
The use of mathematical models is a fundamental aspect of modern science. With computers now allowing previously difficult calculations to be done quickly and easily, an understanding of mathematics and an appreciation for modelling is possible even in fields with traditionally less mathematical content. Modelling Nature introduces basic concepts in mathematical modelling applied to natural systems to tackle real-world problems from fields such as physics, ecology, geology and epidemiology. It shows how using models can help to unravel complex issues such as the melting of the Arctic ice, the spread of infectious disease and the age of the Earth. The text helps students to build steadily upon a basic level of mathematics, to a more advanced understanding of mathematical concepts, for a thorough understanding of a variety of mathematical techniques. Key features include: Worked through calculations, with clear steps that can be followed with just a calculator, pen and paper or popular software packages. Intuitive introduction of advanced mathematical techniques in the context of model building, for an understanding of real-life application. An emphasis on an overall philosophy of building models, drawing repeatedly from the key elements of data, physical processes and mathematical methods to develop and refine models.
Human induced development activities are introduced with insufficient attention to their consequences for our living environment, even in cases where environmental assessments have been carried out. This apparent lack of attention to biodiversity in environmental assessment is rooted in the difficulties we have in adequately addressing biodiversity within the scope, time frame and budget allocated for assessments. This book provides a conceptual background and practical approaches to overcome these difficulties. It integrates the objectives of the Convention on Biological Diversity, its ecosystem approach, and the conceptual framework of the Millennium Ecosystem Assessment into a comprehensive approach to biodiversity in environmental assessment. It highlights the need to consider the value of biodiversity based on its use by each stakeholder, addresses the importance of both social and economic development to reach the Millennium Development Goals, and provides insights into ways to balance present and future needs.
This book addresses the multidisciplinary challenges in biodiversity conservation with a focus on wildlife crime and how forensic tools can be applied to protect species and preserve ecosystems. Illustrated by numerous case studies covering different geographical regions and species the book introduces to the fundamentals of biodiversity conflicts, outlines the unique challenges of wildlife crime scenes and reviews latest techniques in environmental forensics, such as DNA metagenomics. In addition, the volume explores the socio-economic perspective of biodiversity protection and provides an overview of national and international conservation laws. The field of conservation medicine stresses the importance of recognizing that human health, animal health, and ecosystem health are inextricably interdependent and the book serves as important contribution towards achieving the UN Sustainable Developmental Goals, in particular SDG 15, Life on Land. The book addresses graduate students, scientists and veterinary professionals working in wildlife research and conservation biology.
This book is concerned with the paradox that humanity depends on biodiversity and landscape systems for its survival, yet, at the same time, the current burden of humanity's use of living resources places the existence of these natural systems at risk. The role of human values, technological society and social and political processes in the creation and solution of the paradox are explored in this volume, whose origins lie in an international discussion meeting held at the PennState Center for BioDiversity Research. Leading contributors to the fields of biodiversity conservation, ecology, economics, entomology, forestry, history, landscape management, philosophy and sociology draw from their unique disciplinary perspectives to consider the origins, bases and possible solutions to this pressing problem.
In 1992, the Convention on Biological Diversity (CBD), signed by over 160 countries and hailed as the key symbol of a common vision for saving Earth's biodiversity, set forth three primary mandates: preserving biodiversity, using biodiversity components sustainably, and enabling economic benefit-sharing. The CBD-which gave signatory countries the ability to claim sovereignty over nonhuman genetic resources native to each nation-defined biodiversity through a politics of nationhood in ways that commodified genetic resources. In Biogenetic Paradoxes of the Nation Sakari Tamminen traces the ways in which the CBD's seemingly compatible yet ultimately paradox-ridden aims became manifest in efforts to create, conserve, and capitalize on distinct animal and plant species. In using Finland as a case study with which to understand the worldwide efforts to convert species into manifestations of national identity, Tamminen shows how the CBD's policies contribute less to biodiversity conservation than to smoothing the way for frictionless operation of biotechnologically assisted circuits of the global bioeconomy. Tamminen demonstrates how an intimate look at the high-level politics and technical processes of defining national genetic resources powerfully illuminates the limits of anthropocentric biopolitical theory.
Conservation genetics focuses on understanding the role and
requirement of genetic variation for population persistence.
However, considerable debate now surrounds the role of genetic
factors (as opposed to non-genetic factors such as habitat
destruction etc.) in population extinction, and a comprehensive
synthesis is now timely. Can extinction be explained by habitat
destruction alone or is lack of genetic variation a part of the
explanation? The book thoroughly reviews the arguments for a role
of genetics in the present biodiversity crisis. It describes the
methods used to study genetic variation in endangered species and
examines the influence of genetic variation in the extinction of
species.
Understanding the mechanisms driving biological diversity remains a central problem in ecology and evolutionary biology. Traditional explanations assume that differences in selection pressures lead to different adaptations in geographically separated locations. This book takes a different approach and explores adaptive diversification--diversification rooted in ecological interactions and frequency-dependent selection. In any ecosystem, birth and death rates of individuals are affected by interactions with other individuals. What is an advantageous phenotype therefore depends on the phenotype of other individuals, and it may often be best to be ecologically different from the majority phenotype. Such rare-type advantage is a hallmark of frequency-dependent selection and opens the scope for processes of diversification that require ecological contact rather than geographical isolation. Michael Doebeli investigates adaptive diversification using the mathematical framework of adaptive dynamics. Evolutionary branching is a paradigmatic feature of adaptive dynamics that serves as a basic metaphor for adaptive diversification, and Doebeli explores the scope of evolutionary branching in many different ecological scenarios, including models of coevolution, cooperation, and cultural evolution. He also uses alternative modeling approaches. Stochastic, individual-based models are particularly useful for studying adaptive speciation in sexual populations, and partial differential equation models confirm the pervasiveness of adaptive diversification. Showing that frequency-dependent interactions are an important driver of biological diversity, "Adaptive Diversification" provides a comprehensive theoretical treatment of adaptive diversification.
In the last decade biodiversity loss and persistent poverty in developing countries have been recognised as major international problems that require urgent attention. However, the nature and scale of the links between these two problems, and between efforts to address them, has been the subject of much heated debate. Understanding the different elements of this debate is critical if we are to move towards constructive solutions. This Reader provides a guide to, and commentary on, the different strands of the current conservation-poverty debate through a selection of key readings from both the conservation and development literature including policy documents, journal articles and reports. The breadth of material will help readers, including both students and professionals, to locate current debates within their wider contexts. Among the areas of debate covered are: ' The lack of attention to biodiversity concerns in international development policy ' The social implications of protectionist conservation policy ' The roles and responsibilities of conservation NGOs towards local communities ' The links between climate change, biodiversity and poverty reduction, and in particular the implication of discussions around reduced emissions from deforestation (REDD) as a climate change mitigation strategy.
Habitat management is commonly used to maintain and enhance the
biological interest of many areas of semi-natural habitat where
natural processes no longer create suitable conditions for desired
species. Habitat restoration and creation is increasingly being
used to increase the extent of ecologically important habitats in
order to mitigate the impacts of human development. The
modification of past management techniques and the introduction of
new ones can provide additional benefits.
During the Neogene - covering the last 23 Million years - the evolution of the environmental setting in Africa was subject to considerable changes. Natural shifts, slow and rapid, evidenced by modifications in palaeogeography, geodynamics, climate, and vegetation have caused repeated and strong changes of ecosystems in the lower latitudes. Using a variety of proxy data - researched and applied by many authors from numerous disciplines - an attempt is made to reconstruct African landscapes over space and time. Besides such spatio-temporal oscillations in recently humid, semi-humid, and dry areas of Africa, this volume of Palaeoecology of Africa (PoA) focuses on long term interrelationships between ecosystem dynamics and climate change, not ignoring the ever growing and ongoing influence of humans on natural ecosystems since the Quaternary. Regionally, this volume lays a strong focus on Nigeria (Niger Delta). Facing the omnipresent challenges of Global Change, an increasing number of African scientists is involved in palaeoenvironmental and palaeoclimatic research, both theoretical and applied. PoA systematically supports established as well as junior African scientists in the field of sustainable cooperation and academic capacity building. This book will be of interest to all concerned with or interested in up-to-date research on Neogene to Quaternary low latitudes ecosystem changes and their respective interpretation in the framework of natural climate and vegetation change evidenced by a variety of methods that allow to read and learn from the past by following the motto, "The geologic foretime as the key to the present, and possibly to the future." Palynologists, Geologists, Geographers, Archaeologists, and Geomorphologists will find this edition equally useful for their work.
This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasizing the conservation of biodiversity. Sahota Sarkar criticizes previous attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and prediction in traditional ecology and how individual-based models and Geographic Information Systems (GIS) technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyzes the new consensus framework for conservation planning through adaptive management. He concludes with a discussion of the future directions for theoretical research in conservation biology and environmental philosophy.
In the past thirty years biodiversity has become one of the central organizing principles through which we understand the nonhuman environment. Its deceptively simple definition as the variation among living organisms masks its status as a hotly contested term both within the sciences and more broadly. In Eden's Endemics, Elizabeth Callaway looks to cultural objects-novels, memoirs, databases, visualizations, and poetry- that depict many species at once to consider the question of how we narrate organisms in their multiplicity. Touching on topics ranging from seed banks to science fiction to bird-watching, Callaway argues that there is no set, generally accepted way to measure biodiversity. Westerners tend to conceptualize it according to one or more of an array of tropes rooted in colonial history such as the Lost Eden, Noah's Ark, and Tree-of-Life imagery. These conceptualizations affect what kinds of biodiversities are prioritized for protection. While using biodiversity as a way to talk about the world aims to highlight what is most valued in nature, it can produce narratives that reinforce certain power differentials-with real-life consequences for conservation projects. Thus the choices made when portraying biodiversity impact what is visible, what is visceral, and what is unquestioned common sense about the patterns of life on Earth.
With the continual growth of the world's urban population, biodiversity in towns and cities will play a critical role in global biodiversity. This is the first book to provide an overview of international developments in urban biodiversity and sustainable design. It brings together the views, experiences and expertise of leading scientists and designers from the industrialised and pre-industrialised countries from around the world. The contributors explore the biological, cultural and social values of urban biodiversity, including methods for assessing and evaluating urban biodiversity, social and educational issues, and practical measures for restoring and maintaining biodiversity in urban areas. Contributions come from presenters at an international scientific conference held in Erfurt, Germany 2008 during the 9th Conference of the Parties of the Convention on Biodiversity. This is also Part of our Conservation Science and Practice book series (with Zoological Society of London).
Biosphere reserves serve in some ways as "living laboratories" for testing and demonstrating integrated management of land, water and biodiversity. With this publication the national MAB-committee of Germany gives a detailed presentation and description of the Biosphere Reserves of Germany.
This book was published in 2007. Protected areas have emerged as major arenas of dispute concerning both indigenous and environmental protection. In the Malay Archipelago, which contains two of the twenty-five biodiversity hotspots identified globally, rampant commercial exploitation is jeopardizing species and rural livelihoods. While protected areas remain the only hope for the imperiled biota of the Malay Archipelago, this protection requires consideration of the sustenance needs and economic aspirations of the local people. Putting forward the views of all the stakeholders of protected areas - conservation practitioners and planners, local community members, NGO activists, government administrators, biologists, lawyers, policy and management analysts and anthropologists - this book fills a niche in the area of biodiversity, and is a highly valuable and original reference book for graduate students, scientists and managers, as well as government officials and transnational NGOs. |
