This book highlights both the diversity of perspectives and approaches to Arctic research and the inherent interdisciplinary nature of studying and understanding this incomparable region. The chapters are divided into four liberally-defined sections to provide space for dynamic interpretation and dialogue in search of sustainable solutions to the issues facing the Arctic. From governance to technology, scientific research to social systems, human health to economic development, the authors discuss fundamental questions while looking toward the Arctic's future. Whether the reader is well-versed in the history and complexity of Arctic policy or looking for an insightful introduction to the vast world of Arctic research, everyone will find answers that lead to new questions and even more discoveries in these pages, laying the foundation for tomorrow's discussion on the future of the Arctic. The Arctic's unique geographic and political characteristics pose questions for the international community, indigenous peoples, and economic interests not easily answered through traditional concepts. To that end, the Arctic Summer College has been engaging leading professionals, students, scholars, and policy makers from across the globe to exchange ideas and support further investigation into the Arctic. A joint venture between Ecologic Institute US and Ecologic Institute Berlin (Germany), the College participates at the annual Arctic Circle Assembly in Reykjavik, Iceland, and continues to be at the forefront of international collaboration in this critical area of economic, political, environmental, and humanitarian development.
Deep inside caves, at the bottoms of oceans and lakes, beneath the ground: these concealed habitats are absent of sunlight. This strange and fascinating world of complete darkness is not a solitary place-it is inhabited by millions of life forms. Yet most humans-creatures of daylight-have never seen any of them. Until now. In this fascinating-sometimes eerie-book, extreme wildlife photographer and scientist Dante Fenolio brings the denizens of these shadowy haunts into focus. Life in the Dark shows us the many ways in which life forms have adapted to lightless environments, including refinements of senses, evolution of unique body parts, and illumination using "biological flashlights." With more than 200 mesmerizing color photographs, Life in the Dark unveils bizarre creatures like the firefly squid, the giant Amazonian catfish, the Chinese cavefish, and even the human bot fly, which lives in the darkness beneath its host's skin. Fenolio's rich and vibrant images shed new light on the world's fascinating creatures of darkness.
The object of this book is to highlight how the nascent field of sustainability science is addressing a key challenges for scientists; that is, understanding the workings of complex systems especially when humans are involved. A consistent thread in the sustainability science movement is the wide acknowledgement that greater degrees of integration across what are now segmented dimensions of extant Science and Technology systems will be a key factor in matching the most appropriate science and technology solutions to specific sustainability problems in specific places.
This multi-contributor, international volume synthesizes contributions from the world's leading soil scientists and ecologists, describing cutting-edge research that provides a basis for the maintenance of soil health and sustainability. The book covers these advances from a unique perspective of examining the ecosystem services produced by soil biota across different scales - from biotic interactions at microscales to communities functioning at regional and global scales. The book leads the user towards an understanding of how the sustainability of soils, biodiversity, and ecosystem services can be maintained and how humans, other animals, and ecosystems are dependent on living soils and ecosystem services.
The general theme is being based around the ongoing European
Science Foundation SIZEMIC Research Network, which has been running
for several years. The network has focused on the role of body size
in ecosystems and embraces a wide remit that spans all ecosystem
types and a range of disciplines, from theoretical to applied
ecology.
This volume summarizes recent advances in our understanding of the mechanisms that produce successful symbiotic partnerships involving microorganisms. It begins with a basic introduction to the nature of and mechanistic benefits derived from symbiotic associations. Taking that background knowledge as the starting point, the next sections include chapters that examine representative examples of coevolutionary associations that have developed between species of microbes, as well as associations between microbes and plants. The authors conclude with a section covering a broad range of associations between microbes and invertebrate animals, in which they discuss the spectrum of hosts, with examples ranging from bryozoans and corals to nematodes, arthropods, and cephalopods. Join the authors on this journey of understanding!
The focus of this work is the development of models to estimate evapotranspiration (ET), investigating the partitioning between soil evaporation and plant transpiration at field and regional scales, and calculating ET over heterogeneous vegetated surfaces. Different algorithms with varying complexities as well as spatial and temporal resolutions are developed to estimate evapotranspiration from different data inputs. The author proposes a novel approach to estimate ET from remote sensing by exploiting the linkage between water and carbon cycles. At the field scale, a hybrid dual source model (H-D model) is proposed. It is verified with field observations over four different ecosystems and coupled with a soil water and heat transfer model, to simulate water and heat transfer in the soil-plant-atmosphere continuum. At the regional scale, a hybrid dual source scheme and trapezoid framework based ET model (HTEM), using remote sensing images is developed. This model is verified with data from the USA and China and the impact of agricultural water-saving on ET of different land use types is analyzed, in these chapters. The author discusses the potential of using a remote sensing ET model in the real management of water resources in a large irrigation district. This work would be of particular interest to any hydrologist or micro-meteorologist who works on ET estimation and it will also appeal to the ecologist who works on the coupled water and carbon cycles. Land evapotranspiration is an important research topic in hydrology, meteorology, ecology and agricultural sciences. Dr. Yuting Yang works at the CSIRO Land and Water, Canberra, Australia.
This book provides information about microbial mats, from early fossils to modern mats located in marine and terrestrial environments. Microbial mats layered biofilms containing different types of cells are most complex systems in which representatives of various groups of organisms are found together. Among them are cyanobacteria and eukaryotic phototrophs, aerobic heterotrophic and chemoautotrophic bacteria, protozoa, anoxygenic photosynthetic bacteria, and other types of microorganisms. These mats are perfect models for biogeochemical processes, such as the cycles of chemical elements, in which a variety of microorganisms cooperate and interact in complex ways. They are often found under extreme conditions and their study contributes to our understanding of extremophilic life. Moreover, microbial mats are models for Precambrian stromatolites; the study of modern microbial mats may provide information on the processes that may have occurred on Earth when prokaryotic life began to spread."
New Zealand, with its long isolation from other lands and latitudes extending from subtropical to sub Antarctic, has a unique flora and highly diverse vegetation. This book is a comprehensive description of that vegetation, ranging from its origins to the major communities within which the plants exist. The text, supported by over 300 photographs, maps and diagrams, has made an outstanding contribution to the understanding of the biology of these islands. This is a reprint of the volume originally published in 1991. Chapters 1 - 4 describe the New Zealand environment, flora and fauna. They discuss the origin, relationships, life forms and reproductive aspects of the indigenous vegetation. Chapter 5 is a synopsis of vegetation types, habitat classes and environmental processes; it also serves to define the terms that are described in the book. Chapter 6 contains an outline of the geographic divisions of the country. Chapters 7 - 9 offer expanded descriptions of plant communities, preceded, where appropriate, by information on their structure and characteristic species and genera. The concluding chapters discuss ecologic functions and processes. Vegetation of New Zealand is an essential book for botanists, ecologists, conservationists and others who love New Zealand's plants, animals and landscapes. There will also be a large audience outside New Zealand. Its natural vegetation is unique; because of this and the longevity of its evolutionary history, it has always attracted considerable global interest. "The breadth of scholarship displayed by Peter Wardle is impressive. The book as a whole is remarkably readable; testimony to that comes from this reviewer who read all 672 pages in one day and was still captivated at the end " Annals of Botany "A simple title and a great achievement. This is a great book and a major achievement by the author. It will be a source book for many years to come." Vegetation "This book is a magnificent successor to Cockayne's original Vegetation in New Zealand." Biological Conservation
Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.
The global nitrogen cycle is the one most impacted by mankind.
The past decade has changed our view on many aspects of the
microbial biogeochemical cycles, including the global nitrogen
cycle, which is mainly due to tremendous advances in methods,
techniques and approaches. Many novel processes and the molecular
inventory and organisms that facilitate them have been discovered
only within the last 5 to 10 years, and the process is in progress.
This volume provides state-of-the-art updates on methods and
protocols dealing with the detection, isolation and
characterization of macromolecules and their hosting organisms that
facilitate nitrification and related processes in the nitrogen
cycle as well as the challenges of doing so in very diverse
environments. Provides state-of-the-art update on methods and protocols Deals with the detection, isolation and characterization of macromolecules and their hosting organisms deals with the challenges ofvery diverse environments."
Habitat fragmentation and global climate change are the two major environmental threats to the persistence of species and ecosystems. The probability of a species surviving such changes is strongly dependent on its ability to track shifts in the environmental, either by moving between patches of habitat or by rapidly adapting to local condition. These 'solutions' to problems posed by environmental change depend on dispersal propensity, motivating our desire to better understand this important behavior. This book is a comprehensive overview of the new developments in the study of dispersal and the state-of-the-art research on the evolution of this trait. The causes, mechanisms, and consequences of dispersal at the individual, population, and species levels are considered. The promise of new techniques and models for studying dispersal, drawn from molecular biology and demography is explored. Perspectives on the study of dispersal are offered from evolution, conservation biology, and genetics. Throughout the book, theoretical approaches are combined with empirical data, and examples are included from as wide a range of species as possible.
Our interest in the microbial biodegradation of xenobiotics has increased many folds in recent years to find out sustainable ways for environmental cleanup. Bioremediation and biotransformation processes harness the naturally occurring ability of microbes to degrade, transform or accumulate a wide range of organic pollutants. Major methodological breakthroughs in recent years through detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms have provided us unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions. The degradation of a wide spectrum of organic pollutants and wastes discharged into the environment by anthropogenic activities is an emerging need today to promote sustainable development of our society with low environmental impact. Microbial processes play a major role in the removal of recalcitrant compounds taking advantage of the astonishing catabolic versatility of microorganisms to degrade or transform such compounds. New breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are generating vital information which opens a new era providing new insights of metabolic and regulatory networks, as well as clues to the evolution of degradation pathways and to the molecular adaptation strategies to changing environmental conditions. Functional genomic and metagenomic approaches are increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds. New approaches will certainly accelerate the development of bioremediation technologies and biotransformation processes in coming years for natural attenuation of contaminated environments
This book describes various aspects of modern microbiology including microbial enzymes, secondary metabolites, next-generation sequencing, microbial-based biopesticides, microbial-based cancer therapies, biodiesel, and microbial products from fermentation, biodegradation, bioremediation and wastewater treatment. Further, it explains how and why microbes play an important role in preserving the welfare of living beings and the environment. Many bacteria play a significant part in cleaning our environment by detoxifying various xenobiotic compounds, while several microbes produce secondary metabolites that are useful to human beings. The book is divided into 15 chapters that cover various aspects of microorganism-based biotechnology, including recent methodologies such as advanced molecular techniques, as well developments in classical microbiological techniques. The authors also explain how the latest and classical techniques are being used in modern-day microbial biotechnology. All chapters were written by experts from prominent universities, research laboratories, and institutes around the globe. Above all, they focus on recent advances in microbial technology that promote the welfare of living beings and the environment.
The Baltic Sea is an area extensively explored by the oceanographers. Hence it is one of the most often described marine areas in the scientific literature. However, there are still several fields which are poorly investigated and reported by scientists. One of them is the carbon cycle of the Baltic Sea. Although it is believed the shelf seas are responsible for about 20% of all marine carbon dioxide uptake, while they constitute only 7% of the whole sea surface, still a scientific debate exists on the role of the Baltic Sea in the global carbon cycle. "Carbon cycle of the Baltic Sea" is intended to be a comprehensive presentation and discussion of state of the art research by biogeochemists involved in the Baltic Sea carbon cycle research. This work presents both qualitative and quantitative descriptions of the main carbon flows in the Baltic Sea as well as their possible shifts induced by climatic and global change.
In Advances in Entomopathogenic Nematode Taxonomy and Phylogeny the numerous species of Steinernema and Heterorhabditis described since the previous volume, published in 2007, are evaluated and discussed. Valid species proposed from 2007-2015 are covered in detail, each taxon having an illustrated diagnostic description and additional data on molecular characterisation, distribution and biology, etc. An addendum gives brief details of species proposed during 2016. An overview of the taxonomy of the two families provides an up-to-date list of species for both genera, including new synonyms and detailed commentary on specific status where appropriate. Tabular keys to all valid species of Steinernema and Heterorhabditis assist in diagnostics. A chapter on phylogeny and phylogeography completes the book.

1. 1 Nautilus and Allonautilus: Two Decades of Progress W. Bruce Saunders Department of Geology Bryn Mawr College Bryn Mawr PA 19010 wsaunder@brynmawr. edu Neil H. Landman Division of Paleontology American Museum of Natural History New York, New York 10024 landman@amnh. org When Nautilus: Biology and Paleobiology of a Living Fossil was published in 1987, it marked a milestone in cross-disciplinary collaboration. More than half of the contributing authors (36/65) were paleontologists, many of whom were collaborating with neontological counterparts. Their interest in studying this reclusive, poorly known animal was being driven by a search for clues to the mode of life and natural history of the once dominant shelled cephalopods, through study of the sole surviving genus. At the same time, Nautilus offered an opportunity for neontologists to look at a fundamentally different, phylogenetically basal member of the extant Cephalopoda. It was a w- win situation, combining paleontological deep-time perspectives, old fashioned expeditionary zeal, traditional biological approaches and new techniques. The results were cross-fertilized investigations in such disparate fields as ecology, functional morphology, taphonomy, genetics, phylogeny, locomotive dynamics, etc. As one reviewer of the xxxvi Introduction xxxvii book noted, Nautilus had gone from being one of the least known to one of the best understood of living cephalopods.
This book represents a rather complicated history of encounters, changes in research interest and some very interesting results. Initially it is the very fruitful interaction of Ecology and Geology. The point of view of ecologists is extremely refreshing for hard science people. Interaction and inter-relationships are the focus of Ecology whereas the traditional sciences, such as Geology, have tried to isolate the natural phenomena so that thye could be studied in a more rigorous manner. The traditional sciences were of course natural science - based since the world to be observed was at the door step of everyone, mountains, weather patterns, plants and so forth. Chemistry and Physics were de ned after Mathematics in order to establish more precise and viable principles of the behavior of the materials that formed the world around mankind. It became quite clear that the observation of the natural world was too complicated to consider all of the possible variables which could affect an observed process or situation. The systems were simpli ed and taken into the laboratory in order to better master the phenomena observed. Physics c- cerned itself with non-reacting materials, subjected to essentially mechanical forces.
