This updated monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further chapters discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other "methanogenic" mammals contribute significantly to the global methane budget; especially the rumen hosts an impressive diversity of methanogens. This makes this updated volume an interesting read for scientists and students in Microbiology and Physiology.

This book discusses the role of salt in current agricultural approaches, including the low salt tolerance of agricultural crops and trees, impact of saline soils, and salt-resistant plants. Halophytes are extremely salt tolerant plants, which are able to grow and survive under salt at concentrations as high as 5 g/l by maintaining negative water potential. The salt-tolerant microbes inhabiting the rhizospheres of halophytes may contribute to their salt tolerance, and the rhizospheres of halophytic plants provide an ideal opportunity for isolating various groups of salt-tolerant microbes that could enhance the growth of different crops under salinity stress. The book offers an overview of salt-tolerant microbes' ability to increase plant tolerance to salt to facilitate plant growth, the potential of the halophytes' rhizospheres as a reservoir of beneficial salt-tolerant microbes, their future application as bio-inoculants in agriculture and a valuable resource for an alternative way of improving crop tolerance to salinity and promoting saline soil-based agriculture. This special collection of reviews highlights some of the recent advances in applied aspects of plant (halophytes)-microbe interactions and their contribution towards eco-friendly approaches saline soil-based agriculture.

This book shares the latest insights into the genetic basis of molecular communication between plants and their microbial consortia. Further, the book highlights the capabilities of the rhizosphere and endosphere, which help manage ecosystem responses to climate change, nutrient cycling and sequestration of carbon; and discusses their application to the development and management of renewable energy sources. In their natural environments, plants are surrounded by a tremendous number of microorganisms. Some microbes directly interact with plants in a mutually beneficial fashion, while others colonize plants solely for their own advantage. In addition, microbes can indirectly affect plants by drastically altering their environments. Understanding the complex nature of the plant-microbe interface (PMI) can pave the way for novel strategies to improve plant productivity in an eco-friendly manner. The PMI approach focuses on understanding the physical, molecular, and chemical interactions between organisms in order to determine their functional roles in biological, physical, chemical and environmental systems. Although several metabolites from plants and microbes have now been fully characterized, their roles in chemical interactions between these associates remain poorly understood, and require further investigation.

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.

The image of Antarctica as a symbol of the last great wilderness and pristine environment has changed considerably in the last two decades. Environmental problems such as the ozone hole and the break-up of ice-shelves have shown that Antarctica is inextricably linked to global processes and exposed to the impact of human activities in the rest of the world. This volume provides an overview of climate change data, its effects on the structure and functioning of Antarctic ecosystems, and the occurrence and cycling of persistent contaminants. It discusses the unique physico-chemical characteristics of the Antarctic environment, ecophysiological adaptations of terrestrial and marine organisms, the transfer of contaminants in pelagic and neritic food chains and the possible consequences for animals at higher trophic levels. The text concludes with possible future scenarios of climate change and atmospheric contamination and the role of Antarctic organisms in the early detection of environmental perturbations.

This text formally appraises the innovative ways new media artists engage urban ecology. Highlighting the role of artists as agents of technological change, the work reviews new modes of seeing, representing and connecting within the urban setting. The book describes how technology can be exploited in order to create artworks that transcend the technology's original purpose, thus expanding the language of environmental engagement whilst also demonstrating a clear understanding of the societal issues and values being addressed. Features: assesses how data from smart cities may be used to create artworks that can recast residents' understanding of urban space; examines transformations of urban space through the reimagining of urban information; discusses the engagement of urban residents with street art, including collaborative community art projects and public digital media installations; presents perspectives from a diverse range of practicing artists, architects, urban planners and critical theorists.

This book presents a new method for assessing spatial pattern in raster land cover maps based on satellite imagery in a way that incorporates multiple pixel resolutions. This is combined with more conventional single-resolution measurements of spatial pattern and simple non-spatial land cover proportions to assess predictability of both surface water quality and ecological integrity within watersheds of the state of Pennsylvania (USA).

Physical Oceanography of the Dying Aral Sea describes the background, present crisis state, and possible future of this peculiar inland water body from the physical oceanographic standpoint. Based on a wide range of material, a large part of which was published in Russian and has not been previously available to the international reader, the book first provides an historical overview of this unique system, which possesses both lake and sea properties.

Next, the current physical state of the lake is described, partly based on original field research and model experiments, along with the remote sensing data, model results and analyses extracted from recent literature. Next, book attempts to forecast the forthcoming state of the Aral Sea and identify plausible future scenarios. Finally, the book discusses the Aral Sea dessication viewd as a part of the global perspective.

Oases of life around black smokers and hydrocarbon seeps in the deep-sea were among the most surprising scientific discoveries of the past three decades. These ecosystems are dominated by animals having symbiotic relationships with chemoautotrophic bacteria. Their study developed into an international, interdisciplinary venture where scientists develop new technologies to work in some of the most extreme places on Earth. This book highlights discoveries, developments, and advances made during the past 10 years, including remarkable cases of host-symbiont coevolution, worms living on frozen methane, and a fossil record providing insights into the dynamic history of these ecosystems since the Paleozoic.

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.

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.

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.

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.

Pollution doesn't make for easy sonnets or flowing, romantic narratives. And that's what this title is about - pollution. Not the everyday sort of pollution that we recognise so easily, the type which piles up into stinking heaps of litter or that clogs the sky with filthy smoke. No, this is a form of pollution which is so subtle and insidious that many people do not realise it is there. Invaded is about biological pollution, the kind that comes in dense hedges of lush greenery, blooming fields of heady petals or gracefully draped creepers. It may spread incognito on the wings of a bird, tug on the end of an angler's line or scurry unnoticed through the undergrowth. These pages explore plants and animals that have traversed the borders and boundaries of their natural habitats and made their way into South Africa over the past 300 years and more. Unhindered by the predators and diseases which once kept their populations in check, many have come to outnumber and out-compete the species they encounter in their adopted homes. Invaded provides an overview of the different species that have arrived in our country during the past three centuries, and the threats they pose (or have the potential to become). Ultimately, the book attempts to quantify how these species have changed systems, disrupted the natural environment and threatened the future of the country's many unique plants, animals and habitats.

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".
