This second edition of the book, "Green Web-II: Standards and Perspectives from the IUCN Program / Policy Development in Environment Conservation Domain- with reference to India, Pakistan, Nepal, and Bangladesh" investigates the IUCN's role in global biodiversity conservation policy as well as in national program development in India, Pakistan, Nepal and Bangladesh. It explores how nature protection priorities and approaches are promoted or addressed by IUCN, and how environment conservation policies are created and maintained in states of South Asia with different capacities. It also evaluates IUCN's competency in biodiversity, climate change, nature conservation and environmental policy formulation at the global, regional and country levels. This book adds to our knowledge firstly by contributing to a small but growing body of work on the sociology of international organizations. International Governmental Organizations (IGOs), have previously been mainly the subject of political science. Secondly, it critically explores one of the largest and most active nature conservation organizations in the world. Thirdly, it also explores how IUCN actually goes about building protectoral programs with individual member nations. Finally, the research also shows the historical development of global institutions and IUCN's activities with member nations in helping to define or redefine the concept of global governance. The outcomes of this research will also be beneficial for global collaboration, networking, and for the identification of common concerns among the many environmental and conservational organizations at the international and national level. In this broader sense, the research outcomes might be beneficial to constituencies of the global North as well as global South because of the nature and coverage of IUCN and its role in conservation policy formation. This effort may serve as a model for additional research on international organizations. Technical topics discussed in the book include: The Motivation for Environmental Conservation- How personal efforts make a difference The Role of International Environment Conservation Organizations The Political Economy of Organizations, Network theory, Institutional theory, Stakeholder theory, Governance theory Governance performance and Competitiveness Popularity indices Knowledge creation and diffusion Conservation commons
Outside Russia very little is known about the terrestrial ecology, vegetation, biogeographical patterns, and biodiversity of the enormously extensive ecosystems of Yakutia, Siberia. These systems are very special in that they function on top of huge layers of permafrost and are exposed to very severe and extreme weather conditions, the range between winter and summer temperatures being more than 100 degrees C. The soils are generally poor, and human use of the vegetation is usually extensive. Main vegetation zones are taiga and tundra, but Yakutia also supports a special land and vegetation form, caused by permafrost, the alas: more or less extensive grasslands around roundish lakes in taiga. All these vegetation types will be described and their ecology and ecophysiological characteristics will be dealt with. Because of the size of Yakutia, covering several climatic zones, and its extreme position on ecological gradients, Yakutia contains very interesting biogeographical patterns, which also will be described. Our analyses are drawn from many years of research in Yakutia and from a vast body of ecological and other literature in Russian publications and in unpublished local reports. The anthropogenic influence on the ecosystems will be dealt with. This includes the main activities of human interference with nature: forestry, extensive reindeer herding, cattle and horse grazing, etc. Also fire and other prominent ecological factors are dealt with. A very important point is also the very high degree of naturalness that is still extant in Yakutia's main vegetation zones.
This book brings together a selection of 21 original studies submitted to Biodiversity and Conservation that address aspects of management for the conservation of biodiversity. The topics addressed include: lessons from the Northern spotted owl saga, hidden costs of implementing the EU Habitats Directive, the importance of recently created agricultural wetlands, cutting reeds to create a sustainable habitat, impacts and control of feral cats, selecting areas to complement existing reserve systems, beneficial effects of rabbit warrens, effects of fences on large predator ranges, spatial structure of critical habitats and connectivity, effects of an agro-pasture landscape on biodiversity, community involvement, reserve selection in forests, germ-plasm interventions in agroforestry systems, shade coffee plantations and the protection of tree diversity, reserves and the reduction of deforestation rates in dry tropical forests, reconciling forest conservation actions with usage by and needs of local peoples, weed invasion in understory plant communities in tropical lowland forests, problems of patch area and connectivity in plant conservation, the need not to focus just on hot-spots, and partitioning conservation across elevations. The organisms and communities considered embrace birds, coral reefs, various large and small mammals, reptiles, forest trees, and dune and boreal semi-natural grassland plants. The contributions are taken from situations being confronted in regions including the Andaman Islands, Brazil, Canary Islands, the Caribbean, Finland, Germany, Guinea, India, Italy, Mexico, Myanmar, Poland, South Africa, Spain, and the USA. Collectively, the studies presented here provide a snap-shot of the types of management actions being undertaken for conservation and their efficacy. This makes the volume especially valuable for use in conservation biology courses. Reprinted from Biodiversity and Conservation, volume 18, No 4 (2009)
Biological invasions are a global problem whose local impact can be of great magnitude. The prevention and minimization of the impact of invasive alien species has become a priority because of their negative impact on biodiversity, economy and public health. Effective responses are needed; cooperation and coordination among countries and/or different sectors of society are a must. To combine and share experiences on biological invasions at international, regional and local level it is essential to develop compatible approaches to common problems. With this aim, the GEI (Grupo Especies Invasoras) organised the First National Conference on Invasive Alien Species in Spain in 2003. Scientists coming from different parts of the Iberian Peninsula belonging to universities, public administration, NGOs and environmental enterprises and world-renowned experts on biological invasions from other countries responded to this "call for action" and participated in the conference. Issues in Bioinvasion Science contains key contributions of this conference. The themes included cut across different aspects of non-native species invasions. This volume is essential reading for anyone seeking an understanding of non-native species invasions. Our aim: to go beyond national boundaries in order to tackle these complex biological issues.
In 1543, Nicolaus Copernicus fomented a revolution when he debunked the geocentric view of the universe, proving instead that our planet wasn't central to the universe. Almost five hundred years later, the revolution he set in motion is nearly complete. Just as earth is not the center of things, the life on it, it appears, is not unique to the planet. Or is it? "The Life of Super-Earths" is a breathtaking tour of current efforts to answer the age-old question: Are we alone in the universe? Astronomer Dimitar Sasselov, the founding director of Harvard University's Origins of Life Initiative, takes us on a fast-paced hunt for habitable planets and alien life forms. He shows how the search for "super-Earths"--rocky planets like our own that orbit other stars--may provide the key to answering essential questions about the origins of life here and elsewhere. That is, if we don't find the answers to those questions here first. As Sasselov and other astronomers have uncovered planets with mixes of elements different from our own, chemists have begun working out the heretofore unseen biochemistries that those planets could support. That knowledge is feeding directly into synthetic biology--the effort to build wholly novel forms of life--making it likely that we will first discover truly "alien" life forms in an earthly lab, rather than on a remote planet thousands of light years away. Sasselov tells the gripping story of a moment of unprecedented potential--a convergence of pioneering efforts in astronomy and biology to peer into the unknown. "The Life of Super-Earths" offers nothing short of a transformation in our understanding of life and its place in the cosmos.
Water is Life. Freshwater is one of the most valuable commodities on our planet, and this resource should be managed in a sustainable way. Yet, we are less than careful in the way we use water and many of our non-marine, aquatic habitats are threatened by anthropogenic impacts. Eutrophication, for example, could well turn into one of the major social as well as economic problems of the 21st century. Reduction of water quality also has a profound effect on the biota that depend on these water bodies, such as micro-organisms, plants and animals. Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book deals with all of these aspects of Aquatic Biodiversity. It comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.
Protection of the environment has nowadays become a major challenge and a condi tion for survival of future human generations and life on Earth in general. Yet it is still far too much of a dream or hope rather than a reality in the policy of our societies. Presently we are experiencing an unprecedented exponential growth of demography combined with a race for profit, resulting in excessive consumption particularly of en ergy, and a serious impact on the world ecosystems. Various types of pollutants and emerging new diseases not only disrupt the normal course of life, but also above this some of the atmospheric pollutants are most likely involved in the changing climate. We fear and literally shiver at the thought that the "changing climate" would ultimately disrupt the fragile thermodynamic equilibrium between the atmosphere and the oceans. Are we insensitive to these facts to the point of pushing our descendants, some genera tions ahead, into a new glacial period after a first period of warming up, at least, in northern Europe, like the one that took place 13 to 14 millennia ago? Surely the planet's nature is not prepared to be dominated by man and will go its way, whether humanity will be alive or dead."
In this book, numerous prominent aquaculture researchers contribute 27 chapters that provide overviews of aquaculture effects on the environment. They comprise a comprehensive synthesis of many ecological and genetic problems implicated in the practice of aquaculture and of many proven, attempted, or postulated solutions to those problems. This is an outstanding source of reference for all types of aquaculture activities.
In the present volume - the sixth of this series - 48 flowering plant families comprising a total of 712 genera are treated. They represent the newly designed eurosid orders Celastrales, Oxalidales and Rosales and the asterid orders Cornales and Ericales. The recognition of these ordinal concepts is the result of numerous recent gene sequence analyses which, for the first time in angiosperm systematics, have provided a reliable higher order classification. The concept of Ericales is largely expanded beyond its conventional limits to make it monophyletic and now includes parts of the erstwhile Ebenales, Lecythidales, Primulales and other orders. The revised circumscription of families such as Ericaceae, Celastraceae and Cunoniaceae owes much to the application of recent molecular studies, and for the same reason in the primulalean families, a complete remodeling of family limits is proposed.
Building forth upon recent developments in democracy theory that have identified multiple forms of legitimacy, this volume observes a EU-wide shift from output legitimacy to input and throughput legitimacy. Top down policy making is increasingly meeting local resistance. As a result, the importance for policy makers of enhancing the democratic legitimacy of their policy plans has increased. In this volume, nine case studies are presented, seven case studies of protected areas in different countries (Belgium, Germany, Poland, Spain, Finland, France and the UK), and two case studies of protected species (the geese in the Netherlands, and the great Cormorant in Denmark and Italy). These case studies are followed by extensive comments. The volume opens with an introductory chapter on the problematic production of legitimacy in current European nature policy. It concludes with a chapter that situates the case studies within the wider EU environmental policy and political context.
Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.
The book reflects the work in progress regarding the analysis of the costs of crop genetic resources conservation that has been conducted at various research insti tutes over the last couple of years, including research conducted at ZEF and asso ciated institutes. In addition, contributions in this publication were presented at a special session during the "Global Dialogue: The Role of the Village in the 2]'1 Century: Crops, Jobs and Livelihood" in Hannover, Germany, at the World Exposition in Au gust 2000. The purpose of the publication is to make a general contribution to the ongoing discussion about the conservation of crop genetic resources as part of the global strategy to secure increasing food production in a sustainable way. Specifically, it discusses the costs of the worldwide efforts to conserve crop genetic resources on the basis of theoretical and applied studies. It aims to serve decision-makers at dif ferent levels with information on the costs involved in the conservation of genetic resources and hence to increase the awareness of the importance of improving the cost effectiveness of different conservation methods in order to optimize the sus tainability of conservation. The quoted Leipzig Declaration, which was adopted at the Fourth International Technical Conference on Plant Genetic Resources in Leipzig in June 1996, dem onstrates the close linkage of the contributions to the ongoing discussion about the implementation of the Global Plan of Actionfor the Conservation and Sustainable Utili zation of Plant Genetic Resources for Food and Agriculture."
In 2002, sixty international specialists met to discuss problems of high P-unavailability as a soil nutrient for crops, and the hazards of increased phosphate input to aquatic habitats from industrial and mining activities, sewage disposal, detergents, and other sources. Among the presentations were updated solutions to enhance P-uptake by plants, bioremediation potential in the rehabilitation of ecosystems, taxonomic characterization interactions with mycorrizae, the physiological and molecular basis of PSM, and more.
Ancient lakes are exceptional freshwater environments that have continued to exist for hundreds of thousands of years. They have long been recognized as centres of biodiversity and hotspots of evolution. During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology. The contributions in this volume deal with patterns and processes of biological diversification in three prominent ancient lake systems. Of these, the famous East African Great Lakes already have a strong tradition of evolutionary studies, but the two other systems have so far received much less attention. The exceptional biodiversity of the European sister lakes Ohrid and Prespa of the Balkans has long been known, but has largely been neglected in the international literature until recently. The rich biota and problems of its evolution in the two central lake systems on the Indonesian island of Sulawesi, in turn, have only lately started to draw scientific attention. This volume aims at deepening the awareness of the unusual biological diversity in ancient lakes in general, and of the role of these lakes as natural laboratories for the study of speciation and diversification in particular. It should stimulate further research that will lead to a better understanding of key evolutionary processes in these lakes, and to knowledge that might help in mitigating the deterioration of their diversity in the future.
Marine, coastal and wetland habitats are threatened, not only through exploitation, but also by the prospect of climate change as ocean currents change course, sea levels rise, and rainfall patterns change. Even the once-common cod is now under threat from the combined effects of over-fishing and a dramatic change-induced decrease in the plankton that cod larvae feed on. Meanwhile, coral reefs remain especially vulnerable to rapid sea-level changes exacerbated by the effects of tourism and disease. This book gathers together a wide range of papers reporting on key research into the biodiversity conservation of these critical and increasingly threatened habitats. Collectively these papers provide a snap-shot of the types of problems they are experiencing, and offer a wealth of topical examples which render this volume especially valuable to teachers of courses in marine, freshwater and wetlands ecology, biological conservation and ecological restoration."
This book draws together a wide range of papers from researchers around the world that address the conservation and biodiversity of vertebrates, particularly those in terrestrial habitats. Collectively, the papers provide a snap-shot of the types of studies and actions being taken in vertebrate conservation and provide topical examples that will make the volume especially valuable for use in conservation biology courses.
This book offers exchanges between the fields of paleontology and zoology as patterns of biodiversity have long attracted the attention of both biologists and paleontologists. It covers the development of isolated island faunas, paleogeography and zoomorphology. The book shows that patterns are not always what they seem if looked at without a spatial or temporal reference.
This book brings together a selection of original studies that address biodiversity and conservation in Europe. The contributions are drawn from a wide range of countries and discuss diverse organism and habitat types. They collectively provide a snap-shot of the sorts of studies and actions being taken in Europe to address issues in biodiversity and conservation topical examples that make the volume especially valuable for use in conservation biology courses."
A fascinating work that provides a wealth of information on one of the world 's most biodiverse ecosystems. This is the result of investigations by almost 30 groups of researchers from various disciplines. They performed ecosystem analyses following two gradients: an altitudinal gradient and a gradient of land use intensity and ecosystem regeneration following human use. Based on these analyses, this volume discusses these findings in a huge variety of subject areas.
The monitoring of benthic diatoms, macrophytes, macroinvertebrates and fish will be the backbone of future water management in Europe. This book describes and compares the relevant methodologies and tools, based on a large data set covering rivers in most parts of Europe. The 36 articles presented will provide scientists and water managers with a unique insight into background and application of state-of-the-art monitoring tools and techniques.

The Charales are often Spermatophyta (seed-bearing plants), the vegetative mistaken for higher plants because they have erect parts of which actively grow either permanently or central stalks that are divided into short nodes and periodically (for at least several weeks each year) long internodes of elongated multinucleate cells, with submerged below, ?oating on, or growing up through a whorl of "branchlets" at each node (Fig. 1).
One of the central research themes in ecology is evaluating the extent to which biological richness is necessary to sustain the Earth's system and the functioning of individual ecosystems. In this volume, for the first time, the relationship between biodiversity and ecosystem processes in forests is thoroughly explored. The text examines the multiple effects of tree diversity on productivity and growth, biogeochemical cycles, animals, pests, and disturbances. Further, the importance of diversity at different scales, ranging from stand management to global issues, is considered. The authors provide both extensive reviews of the existing literature and own datasets. The volume is ideally suited for researchers and practitioners involved in ecosystem management and the sustainable use of forest resources.
The Thar Desert, also known as the Great Indian Desert, is a large, arid region in the 2 northwesternpartoftheIndiansubcontinent.Withanextentof280,000km, itisthe 17th largest desert in the world. It lies mostly in the Indian state of Rajasthan, and extends into the southern portion of Haryana and Punjab and into northern Gujarat. The Thar Desert is bounded in the northwest by the Sutlej River, in the east by the Aravalli Range, in the south by a salt marsh known as the Rann of Kutch, and in the west by the Indus River. In spite of the fact that climatic conditions are very harsh, this extremely hot region of the country exhibits a vivid and spectacular biodiversity. It is an important area biologically, at the con?uence of very different habitats, namely grassland, sand dunes and rocky expanses as well as forested domains. Due to the diversi?ed ha- tats, the vegetation and animal life in this arid region are very rich. Some wildlife species, fast disappearing from other parts of India, are found in large numbers in this desert, such as the Great Indian Bustard, Blackbuck, Indian Gazelle and Indian Wild Ass in the Rann of Kutch. The Desert National Park is an excellent example of theThar Desertecosystem, anditsdiverse fauna.The region isahaven formigratory and resident desert birds.
Fluctuations in the environmental conditions impacting life are ubiquitous. This book brings together contributions to provide readers with a comprehensive look at the challenges for ecological systems and ecological research alike. It offers a comprehensive range of topics, from environmental variability itself to its ecosystem-level impact. |
