It includes regular re?lling of their aquatic habitat with a source macroalgae of the divisions Chlorophyta (green of fresh to brackish water. algae), Xanthophyta (yellow-green algae) and Rho- The freshwater macroalgae are primarily rep- dophyta (red algae) and the "blue-green algae" (more sented by the green algae, especially the Charales, correctly known as Cyanobacteria), Bryophyta commonly known as the stoneworts or brittleworts (mosses and liverworts), Pteridophyta (ferns) and (e.g., Chara and Nitella spp.). 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).
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.
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.
Original studies address key aspects of the conservation and biodiversity of plants. Articles are all peer-reviewed primary research papers, contributed by leading biodiversity researchers from around the world. Collectively, these articles provide a snapshot of the major issues and activities in global plant conservation. Many of the articles can serve as excellent case studies for courses in ecology, restoration, biodiversity, and conservation.
The goal of this transdisciplinary book is to identify the problems and challenges facing implementation of the Convention on Biological Diversity (CBD) - from the global, regional and local points of view. The valuation and conservation of biodiversity are critical first steps necessary for the adequate protection of the environment. The authors give insights into the the influences the CBD exerts, and current trends in the field.
Capitalizing on forty years of intensive ecological studies, this anthology presents a collection of widely dispersed major publications on theoretical and practical Mediterranean, global environmental and landscape issues. Each chapter features a comprehensive study of ecological and landscape issues, synthesized in the introduction, and woven with autobiographical experiences. The concluding chapter calls for a transdisciplinary shift in all environmental scientific fields and particularly in landscape and restoration ecology, to cope with the complex, closely interwoven ecological, socio-economical, political and cultural crises facing human society during the present crucial transition from the industrial to the post-industrial, global information age. Updating and broadening the scope of the groundbreaking Springer book on Landscape Theory and Applications by the author and Lieberman (1994), this is a unique transdisciplinary attempt based on advanced systems complexity theories, which link the natural and human sciences.
This volume contains a complete systematic treatment of the flowering plant order Asterales. This comprises 12 families with approx. 1,720 genera and about 26,300 species. Identification keys are provided for all genera, and likely phylogenetic relationships are discussed extensively. The wealth of information contained in this volume makes it an indispensable source for all working in the fields of pure and applied plant sciences.
The current, unprecedented loss of global biodiversity resulting from anthropogenic interference in the world's ecosystems is affecting human well-being across the globe with increasing severity. This book examines two issues that are at the center of the public discussion on biodiversity. It examines whether genetic information derived from biodiversity can be used to create incentives to preserve biodiversity. Then, it examines whether establishing protected areas can be accomplished on an international level by using transfer payments.
Invasive species have come to dominate 3% of the Earth s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.
The Goodwin-Niering Center for Conservation Biology and Environmental Studies at Connecticut College is a comprehensive, interdisciplinary program that builds on one of the nation's leading undergraduate environmental studies programs. The C- ter fosters research, education, and curriculum development aimed at understanding contemporary ecological challenges. One of the major goals of the Goodwin-Niering Center is to enhance the understanding of both the College community and the general public with respect to ecological, political, social, and economic factors that affect natural resource use and preservation of natural ecosystems. To this end, the C- ter has offered six conferences at which academicians, representatives of federal and state government, people who depend on natural resources for their living, and in- viduals from non-government environmental organizations were brought together for an in-depth, interdisciplinary evaluation of important environmental issues. On April 6 and 7, 2007, the Center presented the Elizabeth Babbott Conant interdisciplinary conference on Saving Biological Diversity: Weighing the Protection of Endangered Species vs. Entire Ecosystems. The Beaver Brook Foundation; Audubon Connecticut, the state of?ce of the National Audubon Society; the Connecticut Chapter of The Nature Conservancy; Connecticut Forest and Park Association and the Connecticut Sea Grant College Program joined the Center as conference sponsors. During this two-day conference we learned about conservation and endangered species fromawiderange ofperspectives. Likeallof theconferences sponsored bythe Goodwin-Niering Center, this conference was broadly interdisciplinary, with pres- tations by economists, political scientists, and conservation biologists.
This book provides the first synthesis of the remarkable diversity, evolutionary complexity, and conservation importance of the flora and fauna in the Mediterranean region, with emphasis on the three major peninsular refugia. The book highlights biodiversity importance in Southern Europe for European biota conservation, and includes chapters from authorities in phylogeography: John Avise, Remy Petit, Ettore Randi.
Johannes Klumpers Biotechnologies, such as genetic engineering, cloning and biodiversity, raise many legal and ethical concerns, so it is important that people understand these issues and feel able to express their opinions. This is why the European Commission has been, for a number of years, supporting actions to improve communication among scientists in these diverse areas. The project 'Women in Biotechnology' (WONBIT), financed under the 6th Framework programme of the European Commission, is an excellent example of what can be done to target opinion-formers such as scientists, economists and lawyers in bottom-up activities, and to encourage a debate on gender issues triggered by developments in the life sciences. WONBIT gave rise to a successful international conference highlighting the importance of adopting good practices and ethical considerations in parallel with the rapid pace of progress in biotechnology - from a woman's point of view. In particular, the conference addressed women in decision-making positions in b- technology with specific reference to scientific excellence, social competencies and management qualities as well as issues relating to environment, society and the younger generation. But it did not stop there: a key part of the conference was dedicated to stimulating public debate among non-specialists, which has led to a number of recommen- tions to policy-makers on better communication in biotechnology, on taking better account of the gender aspects of research, and on involving more women in the decision-making process that surrounds developments in biotechnology.
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
Marine hard bottoms feature some of the most spectacular and diverse biological communities on this planet. These not only contain a rich treasure of genetic, taxonomic and functional information but also deliver irreplaceable ecosystem services. At the same time, they are highly vulnerable and increasingly threatened by anthropogenic pressures. This volume has collected contributions by 50 scientists from numerous biogeographic regions, dealing with characteristics of hard bottom communities. Distributional patterns in space and time are described, followed by analyses of the intrinsic and extrinsic dynamics producing these patterns. A strong emphasis is placed on the ongoing changes occurring in the structure and diversity of these communities in response to spiralling environmental impacts, and on state-of-the-art countermeasures aiming to preserve these ecological treasures. Finally, various values of diversity are assessed, hopefully as an incentive for enhanced conservation efforts.
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.
With millions of different bacterial species living in soil, the microbial community is extremely complex, varying at very small scales. Microbe-driven functions are essential for most processes in soil. Thus, a better understanding of this microbial diversity will be invaluable for the management of the various soil functions. Nucleic Acids and Proteins in Soil combines traditional approaches in soil microbiology and biochemistry with the latest techniques in molecular microbial ecology. Included are methods to analyse the presence and importance of nucleic acids and proteins both inside and outside microbial cells, the horizontal gene transfer which drives bacterial diversity, as well as soil proteomes. Further chapters describe techniques such as PCR, fingerprinting, the challenging use of gene arrays for structural and functional analysis, stable isotope probing to identify in situ metabolic functions, and the use of marker and reporter genes in soil microbial ecology.
In the last few decades more and more yeast habitats have been explored, spanning cold climates to tropical regions and dry deserts to rainforests. As a result, a large body of ecological data has been accumulated and the number of known yeast species has increased rapidly. This book provides an overview of the biodiversity of yeasts in different habitats. Recent advances achieved by the application of molecular biological methods in the field of yeast taxonomy and ecology are also incorporated in the book. Wherever possible, the interaction between yeasts and the surrounding environment is discussed.
Natural resource governance is central to the outcomes of biodiversity conservation efforts and to patterns of economic development, particularly in resource-dependent rural communities. The institutional arrangements that define natural resource governance are outcomes of political processes, whereby numerous groups with often-divergent interests negotiate for access to and control over resources. These political processes determine the outcomes of resource governance reform efforts, such as widespread attempts to decentralize or devolve greater tenure over land and resources to local communities. This volume examines the political dynamics of natural resource governance processes through a range of comparative case studies across east and southern Africa. These cases include both local and national settings, and examine issues such as land rights, tourism development, wildlife conservation, participatory forest management, and the impacts of climate change, and are drawn from both academics and field practitioners working across the region.

Balkan Biodiversity is the first attempt to synthesise our current understanding of biodiversity in the great European hot spot. The conservation of biodiversity is one of today s great ecological challenges but Balkan biodiversity is still poorly understood, in a region with complex physical geography and a long history of political conflict. The Balkans exhibit outstanding levels of endemism, particularly in caves and ancient lakes such as Ohrid; lying at the crossroads of Europe and Asia they are also renowned as a focus of Pleistocene glacial refugia. This volume unites a diverse group of international researchers for the first time. Its interdisciplinary approach gives a broad perspective on biodiversity at the level of the gene, species and ecosystem, including contributions on temporal change. Biological groups include plants, mammals, spiders and humans, cave-dwelling organisms, fish, aquatic invertebrates and algae. The book should be read by zoologists, botanists, speleobiologists, palaeoecologists, palaeolimnologists and environmental scientists."
This book presents a wide range of contributions addressing diverse aspects of biodiversity exploitation and conservation. These collectively provide a snapshot of ongoing action and state-of-the-art research, rather than a series of necessarily more superficial overviews. Examples presented here derive from studies in 17 countries including Africa, Asia, Europe, and North and South America. These reports will stimulate future work toward attaining a sustainable balance between the conservation and exploitation of biodiversity.
This book examines one of the most important and complex of the world's tropical rainforest regions: the greater Panama Canal Watershed. The Rio Chagres is the primary water source for operating the Canal, and supplies potable water for municipal use and electricity generation, but science has left this important national resource largely unstudied. The text promotes understanding of the physical and ecological components of an isolated and largely pristine tropical rainforest.
The Middle Paran river is one of the largest in the world. Exceptionally rich in fauna and flora, it provides researchers with a glimpse into an ecosystem yet undisturbed by human civilization. This fascinating book covers all the key aspects of the Paran 's fluvial limnology and ecology, arranged in discrete and easily navigable sections. First, the physical and chemical environment is explained, then the river 's plant life, followed by its invertebrate life, and finally the vertebrates that inhabit the river.
Fred Van Dyke 's new textbook, Conservation Biology: Foundations, Concepts, Applications, 2nd Edition, represents a major new text for anyone interested in conservation. Drawing on his vast experience, Van Dyke 's organizational clarity and readable style make this book an invaluable resource for students in conservation around the globe. Presenting key information and well-selected examples, this student-friendly volume carefully integrates the science of conservation biology with its implications for ethics, law, policy and economics.
This book offers a thorough and up-to-date treatment of the use of morphometric procedures in a wide variety of contexts. As one of the most dynamic and popular fields on the contemporary biological scene, morphometrics is gaining notice among researchers and students as a necessary complement to molecular studies in the understanding and maintenance of biodiversity. This is the first reference to meet that growing need.
The main themes of the Symposium were biodiversity in enclosed and semi-enclosed seas and artificial habitats, and the restoration of degraded systems. These themes are highly relevant today. The papers dealing with the first theme represent current research and concerns about marine biodiversity in enclosed seas. The papers in the second theme represent a synthesis of up-to-date knowledge on artificial habitats. |
