Towards a Thermodynamic Theory for Ecological Systems (Paperback): S.E. Jorgensen, Y.M. Svirezhev Towards a Thermodynamic Theory for Ecological Systems (Paperback)
S.E. Jorgensen, Y.M. Svirezhev
R2,492 Discovery Miles 24 920 Ships in 10 - 15 working days

The book presents a consistent and complete ecosystem theory based on thermodynamic concepts. The first chapters are devoted to an interpretation of the first and second law of thermodynamics in ecosystem context. Then Prigogine's use of far from equilibrium thermodynamic is used on ecosystems to explain their reactions to perturbations. The introduction of the concept exergy makes it possible to give a more profound and comprehensive explanation of the ecosystem's reactions and growth-patterns. A tentative fourth law of thermodynamic is formulated and applied to facilitate these explanations. The trophic chain, the global energy and radiation balance and pattern and the reactions of ecological networks are all explained by the use of exergy. Finally, it is discussed how the presented theory can be applied more widely to explain ecological observations and rules, to assess ecosystem health and to develop ecological models.

Pot-Honey - A legacy of stingless bees (Hardcover, 2013 ed.): Patricia Vit, Silvia R. M. Pedro, David Roubik Pot-Honey - A legacy of stingless bees (Hardcover, 2013 ed.)

R7,086 Discovery Miles 70 860 Ships in 18 - 22 working days

The stingless bees are one of the most diverse, attractive, fascinating, conspicuous and useful of all the insect groups of the tropical world. This is a formidable and contentious claim but I believe it can be backed up. They are fifty times more species rich than the honey bees, the other tribe of highly eusocial bees. They are ubiquitous in the tropics and thrive in tropical cities. In rural areas, they nest in a diversity of sites and are found on the flowers of a broad diversity of crop plants. Their role in natural systems is barely studied but they almost certainly deserve that hallowed title of keystone species. They are popular with the general public and are greatly appreciated in zoos and gardens. The chapters of this book provide abundant further evidence of the ecological and economic importance of stingless bees.

New Zealand Freshwater Fishes - an Historical and Ecological Biogeography (Hardcover, Edition.): R.M. McDowall New Zealand Freshwater Fishes - an Historical and Ecological Biogeography (Hardcover, Edition.)
R.M. McDowall
R5,234 Discovery Miles 52 340 Ships in 18 - 22 working days

This book provides a synthesis of taxonomic and ecological information on New Zealand's freshwater fish fauna. New Zealand has been isolated in the southwestern Pacific Ocean since it separated from Gondwana during the Cretaceous period, some 80 million years ago. This prolonged geological isolation, combined with the islands' very vigorous geological history, impacted by oceanic submergence, tectonic activity, mountain building extreme volcanism, and great climatic variability, create a dynamic scenario within which the New Zealand biota, including its freshwater fishes, have evolved over millions of years. These impacts have contributed to a highly dynamic biological history with undoubted though little understood extinction and vigorous colonisation of the islands' fresh water. One of the key elements for understanding the origins and derivations of this fish fauna is that in all groups some or all of the species are diadromous, customarily spending a significant phase of their lives at sea. This has no doubt contributed in an important way the fauna's origins as well, there has been frequent loss of diadromous behaviours leading, to species that have abandoned their sea-migratory behaviours and which now complete their entire lives in fresh water. The distribution patterns reflect these changing habits, with diadromous species being broadly distributed but tending to be lowland in range, whereas the derived, non-diadromous species have narrower ranges, but are often found further inland and at high elevations. This book provides an ecological and historical synthesis of these divergent patterns across New Zealand's geography and history.

Cyanobacteria for Bioremediation of Wastewaters (Hardcover, 1st ed. 2016): Inga Zinicovscaia, Liliana Cepoi Cyanobacteria for Bioremediation of Wastewaters (Hardcover, 1st ed. 2016)
Inga Zinicovscaia, Liliana Cepoi
R3,172 Discovery Miles 31 720 Ships in 18 - 22 working days

This book reflects the use of cyanobacteria for the bioremediation of wastewater through different mechanisms and pathways of transformation and transfer of hazardous substances from one medium to another. The application of microorganisms for bioremediation is determined by their ubiquity, small size, high rate of reproduction and large surface-to-volume cell ratio. Mechanisms of interaction of cyanobacteria with inorganic pollutants include biosorption, bioaccumulation with an opportunity to obtain metal nanoparticles both on the cell surface and inside the cells as well as chelation and inclusion of metals in the composition of certain organic structures. Data presented in the book provides specialists in the field with useful information for bioremediation technologies as well as for obtaining valuable preparations using cyanobacteria.

The 8th International Congress of Ecology was held in Seoul, South Korea in August 2002, and was hosted by the Ecological Society of Korea. The Congress theme was 'Ecological Issues in a Changing World', and this volume includes selected contributions to illustrate some of the important topics which were discussed during the Congress.

Problems of scale have exercised the minds of ecologists for many years, and will continue to do so into the future. This volume deals with this subject and with mathematical approaches to improve our understanding of complex ecological systems. The book also concentrates on monitoring the responses of ecosystems, especially to human impacts upon them. The importance of spatial separation of function at both the landscape and ecosystem level forms an important theme. Finally, this special book focuses on large-scale issues, discussing in particular important applied ecological problems and how these can be managed through a variety of planning processes. Many examples of major ecological problems in the mainstream ecological literature are drawn from Europe and North America. In contrast, many of the most pressing ecological problems are to be found elsewhere in the World.

This volume is composed of four parts according to scale, objectives and application of modern ecological research. Part I covers emerging concepts and models in the ecosystem complex and in the landscape. Part II. Biological responses to environmental changes: pattern and process, Part III. Ecological networking and restoration technology: theory and practice, and finally a summary of 8th INTECOL Congress and possible future directions are covered in Part IV.

Thomas Kvan, Justyna Karakiewicz
R2,653 Discovery Miles 26 530 Ships in 18 - 22 working days

This book addresses the future of urbanisation on the Galapagos Islands from a systems, governance and design perspective with the competing parameters of liveability, economic and ecological, using the Galapagos as a laboratory for the theoretical and postulative understanding of evolving settlement and habitation. The Galapagos islands are one of the world's most examined and reported examples of a series of naturally evolving ecosystems. The biodiversity of these island ecosystems are the focus of tourism and the image across the world yet human settlement are part of the local ecology. While human intervention is limited, the islands are a distinctive context in which to consider the impact of human habitation as a part of our ecosystems. In this book, authors take the framework of complex adaptive systems (CAS) in which to model systems that grow and evolve, the relations between these various sectors change; systems that get more complex as they evolve. Tested and applied discretely in the two realms of natural and urban, for the first time this text will bring the two together in understanding options for the future of urban settlements on the Galapagos Islands and, by extension, consider how the approach can be used globally in other contexts.

Large lakes are important because of their size and ecological distinctiveness as well as their economic and cultural value. Optimal management of them requires a proper understanding of anthropogenic impacts both on the lake ecosystems as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles and food-web structure, are all directly related to their size. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered. These vulnerable ecosystems often suffer from accelerated eutrophication, over-fishing, toxic contamination and invasive species. Large lakes offer socio-economic benefits and can be used in many ways, and are often areas in which economic, cultural and political interests overlap. In this book the problems regarding the present status of European large lakes and the directions of change are discussed. Threats caused by direct human impact and by climate change, protection needs and restoration measures are considered.

Yoque en el campo he nacido dig6 que mis cantos son para los unos sonidos, y para otros intencion. H. Hernandes - Martin Fierro. The period of active influence of the people on desert environments in Central Asia counts more than 2,000 years. It includes several stages of the social and the economic development of human society - from primitive culture of hunters to developed modern society with great changes of envi- ronment and "nature remaking".Heritage of the past is one of the main causes of land degradation in Central Asia.So, only historical analysis of relations between the man and the desertcould give infor- mation for awareness of desertification. What an idea have the people about the desert? In the mind of many people "desert" is identified with a sterile, lifeless and gloom land unsuitable for life. The mass media, specially the cinema sup- ports this idea. Very popular subject of many films is the death of travelers in the desert from thirst. Eventhe names of hot winds (the "gibly" inSahara, the "samum" inArabian desertand the "afganets" inCentral Asia) fill the minds of peoplewith horror. There are many legends about armies buried inthe sand,aboutflourishing oases and towns covered with sand drifts. Inthese legends the truth is mixed with fiction. But as known, "the truth isstronger than fiction".

Francesco M Angelici
R4,180 Discovery Miles 41 800 Ships in 18 - 22 working days

This book provides insight into the instances in which wildlife species can create problems. Some species trigger problems for human activities, but many others need humans to save them and to continue to exist. The text addresses issues faced by economists and politicians dealing with laws involving actions undertaken to resolve the problems of the interaction between humans and wildlife. Here, the words 'problematic species' are used in their broadest sense, as may be appreciated in the short introductions to the various sections. At times, the authors discuss special cases while always extending the discussion into a more general and broad vision. At others, they present real cutting-edge analysis of ecological topics and issues. The book will be of interest to biologists, ecologists and wildlife managers involved in research on wildlife, parks, and environmental management, as well as to government departments and agencies, NGOs and conservation wildlife organizations. Even those in contact with nature, such as hunters, herders, and farmers, will be able to find a great deal of important information. Specific case studies are selected from among the most significant and prevalent cases throughout the world. A total of 26 papers have been selected for this book, written by zoologists, biologists and ecologists. Many have an interdisciplinary approach, with contributions by economists, criminologists, technical specialists, and engineers.

This book presents studies on current vegetation topics, from polar to tropical regions. It is a festschrift to mark the 70th birthday of Prof. Elgene O. Box, who has studied vegetation all over the world, both through fieldwork and modeling. It reflects a number of his interests, including basic ecological plant forms (cf 'plant functional types'), temperate-zone forests, and evergreen versus seasonal patterns. Section 1 discusses the concept of vegetation series, while Section 2 has two global-scale chapters on plant functional traits and whether they are related more to climate or phylogeny. Section 3 has nine chapters focusing on vegetation history, regional vegetation, and how these have influenced current species organizations and distributions. Regions treated include Russia, China, the USA, Mexico and Mediterranean areas. Lastly, Section 4 addresses aspects of vegetation change and plant ecology. Every chapter in this unique book offers original ideas on the topic of vegetation, as the authors are assembled from a world-wide population of leading vegetational ecologists, whose interests range from local communities to global theoretical questions.

R4,121 Discovery Miles 41 210 Ships in 18 - 22 working days

The ten-year research program and the Kapalga fire experiment at CSIRO in Australia has provided a wealth of knowledge about savanna ecosystems and the critical but poorly understood role of fire. The frequent low intensity fires examined in this volume characterize fire in the tropics and are a dominant force in shaping the structure and function of tropical ecosystems. Contributors discuss fire in relation to rainfall, groundwater, and the mammals and plants in the ecology and management of ecosystems. Among the management issues addressed are: habitat management, endangered species, protection of people and property, erosion and nutrient depletion, integration of knowledge from indigenous people and western science, and atmospheric pollution from fire smoke. This book will be valuable to tropical and savanna ecologists, fire ecologists and fire managers throughout the world, whether they are interested in plants, animals, soils or in the landscape as a whole.

The rhizosphere is a very complex environment in which the effects of the plant on soil microorganisms and the effects of the microorganisms on the plant are interacting and are interdependent. Plant root exudates and breakdownproducts attract microbes and feed them and, in turn, the plants often bene't from the microbes. Interactions among microorg- ismsandplantrootsareessentialfornutritionalrequirementsoftheplant. Plant growth, development and productivity are largely dependent on the soil environment in the root region rhizosphere. The new techniques of studying the rhizosphere enables us to get a much better understanding of the dynamics of the rhizosphere population, such rhizosphere studies beingofinteresttoagriculturists, soilbiologists, chemists, microbiologists andmolecularbiologists.

This work assesses the issues facing biodiversity maintenance on tropical islands, and the impacts of biodiversity loss. The emphasis is on the Indo-West Pacific region, which includes many small islands where the biodiversity is under threat as a result of not only climate change and habitat destruction, but invasions by organisms previously absent from an island. The contributors are distinguished biodiversity scientists from inside and outside the region, and cover topics ranging from the state of conservation action in South-East Asia, the role of parks, and the status and threat to endemics, to impacts of oil and gas exploration and forest fragmentation. Issues needing still to be addressed, especially in relation to implications of biodiversity loss or change for the maintenance of ecosystem processes, are highlighted. The conclusions and case studies have lessons for all involved in the conservation of the biotas and ecosystems of islands. Previously published in Biodiversity and Conservation 19:2 2010

R2,774 Discovery Miles 27 740 Ships in 18 - 22 working days

Over the last decades, scientists have been intrigued by the fascinating organisms that inhabit extreme environments. These organisms, known as extremophiles, thrive in habitats which for other terrestrial life-forms are intolerably hostile or even lethal. Based on such technological advances, the study of extremophiles has provided, over the last few years, ground-breaking discoveries that challenge the paradigms of modern biology. In the new bioeconomy, fungi in general, play a very important role in addressing major global challenges, being instrumental for improved resource efficiency, making renewable substitutes for products from fossil resources, upgrading waste streams to valuable food and feed ingredients, counteracting life-style diseases and antibiotic resistance through strengthening the gut biota, making crop plants more robust to survive climate change conditions, and functioning as host organisms for production of new biological drugs. This range of new uses of fungi all stand on the shoulders of the efforts of mycologists over generations. The book is organized in five parts: (I) Biodiversity, Ecology, Genetics and Physiology of Extremophilic Fungi, (II) Biosynthesis of Novel Biomolecules and Extremozymes (III) Bioenergy and Biofuel synthesis, and (IV) Wastewater and biosolids treatment, and (V) Bioremediation.

Steven J. Kennelly
R4,043 Discovery Miles 40 430 Ships in 18 - 22 working days

This book comes after several decades of outstanding and successful research that has helped ameliorate some of the most important and controversial fisheries issues in the world a" those associated with the unwanted wastage of fish from by-catch and discarding.

The 8 chapters encompass contributions from 27 of the worlda (TM)s leading experts in by-catch reduction. They take the reader through most aspects of the field at a variety of scales and viewpoints. They examine the methodologies used to develop by-catch reduction techniques and provide new avenues for assisting and broadening such work. Case studies are provided that encompass most of the worlda (TM)s fishing techniques and regions.

Solutions developed for the most problematic fishing methods in terms of by-catch, selectivity and habitat damage are examined in significant detail in addition to ways to reduce the by-catch of charismatic species like marine mammals and sea-birds. By-catch reduction in less infamous fishing methods is also examined with chapters on recreational fishing and trapping. The book shows how the lessons learned in reducing by-catch can be applied to ameliorate emerging, broader issues concerning the impacts of fishing on entire ecosystems. Finally, the book examines the most vital phase of by-catch reduction work - its uptake and extension into fishing practices.

This book will prove an invaluable tool for any fisheries professional or lay person interested in by-catch reduction or, indeed, anyone trying to resolve a particular by-catch problem in their fishery.

R5,283 Discovery Miles 52 830 Ships in 18 - 22 working days

Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems. Written for: All who are interested in parthenogenesis and evolutionary biology, including undergraduate and graduate students and senior researchers

What exactly is our relationship with insects? Are they more beneficial or harmful? What role do they play in the world? What are the effects of climate change: Will the number of insects continue to increase? This book discusses the beneficial and harmful effects of insects and explains their development and significance for biodiversity. This second, fully reviewed and enlarged, edition provides new insights, especially about the value of specific insect species that are generally seen as pests (e.g. ants and moths), as well as an extended chapter on the development of insects and especially their decline in different regions in the world, the industrialized countries in particular. Numerous info graphics show connections between changes in the environment due to human expansion and the number of insects and species. Studies from the US, Canada, Asia, Africa, Europe and Switzerland are used to point out the dramatic reduction of biodiversity. New tables illustrate these developments. The glossary as well as the insects index is extended, the text, tables, pictures and graphs provide even more well-rounded image. Readers will find the argumentation even more clearly and detailed.
