Life in the Universe : Expectations and Constraints
Energy, chemistry, solvents, and habitats -- the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space. While speculative considerations in this emerging field of science cannot be avoided, the authors have tried to present their study with the breadth and seriousness that a scientific approach to this issue requires. They seek an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter and avoid scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.
Life in Extreme Environments
Investigating life processes under extreme conditions can also bring clues for understanding and predicting ecosystems' responses to global changes. Furthermore, this area of research has a wide application potential in the fields of (bio)technoloty, chemical industry, pharmaceutics, biomedicine or cosmetics.
Life as We Know It
Life As we Know It ["LAKI"] covers several aspects of Life, ranging from the prebiotic level, origin of life, evolution of prokaryotes to eukaryotes and finally to various affairs of human beings. Although it is hard to define Life, one can, however, characterize it and describe its features. Topics treated are categories of bacteria, algae and fungi, conscience, philosophy, theology, aesthetics, appearance of sport and life destiny, life after clinical death, and thoughts of the world to come ("Olam Haba"). The various chapters have been written so that they are accessible to all - from the avid lay reader to the specialist – and make available multidisciplinary sources of information about Life. This volume will interest open minded scholars, students at all levels of general sciences, natural and Life science, researchers of philosophy, theology, history of Life, astrobiology, and those who wish to widen their knowledge about "who are we in the universe".
Lessons Learned : Risk Management Issues in Genetic Counseling
The only book devoted exclusively to this specialty, Lessons Learned details the risk management issues involved in genetic counseling practice, and offers solid strategies for minimizing the risk of costly, career-damaging malpractice suits. Schmerler clearly identifies areas of practitioner liability and demonstrates how they may be averted, so counselors can better manage their practice while lowering the risk of legal action. Examples drawn from relevant court cases illustrate typical issues in malpractice, negligence, and breach of contract suits. With this in-depth knowledge, readers can refine their goals toward increased self-protection as well as client care.

Lemurs : Ecology and Adaptation
In this comprehensive volume, written by experts in the field, information gathered on lemur ecology and adaptation over the past 15 years is presented by both seasoned and newer lemur researchers, and provides us with further knowledge concerning both well-studied and rarely studied extant species, as well as insights into the ecology and adaptation of some of the recently extinct lemurs.
Legionella Pneumophila : Pathogenesis and Immunity
Legionella pneumophila is an emerging human pathogen that resides in natural environments as a parasite of freshwater. The volume brings together all of the lastest research on this pathogen, the interest in which is rapidly growing.
Left-right asymmetry in vertebrate development
A host of studies has unravelled the involvement of many genes in the left right patterning pathway. Based on this knowledge the genetic basis of human laterality defects are beginning to be revealed. It is a major challenge now to understand how all these genes control left right development as well as the complex set of interactions established between them.
Lectins
In the intervening years well over 10,000 articles have appeared with lectins as the main subject, and more than twice as many in which they were touched upon, as well as around 20 books. In particular, great strides have been made in several areas of lectin research, about which little was known until the late 1980s. One prominent example is animal lectins, many of which have been discovered only during the last decade and the functions of several of which have been clarified, especially as to their key role in innate immunity.
Latency Strategies of Herpesviruses
This is the first book dealing with the intricate epigenetic mechanisms (DNA methylation, histone modification, alteration of chromatin structure) that regulate latency-associated transcription. Special attention is given to immune evasion "tricks" blocking immune responses to herpesvirus infected cells and viral RNAs and proteins involved in malignant transformation.
Landscapes, Genomics and Transgenic Conifers
What is the future of genetically modified (or transgenic) conifer plantations? The content of this edited volume Landscapes, Genomics and Transgenic Conifers addresses this question directly - and indirectly - using language drawn from policy, forest history, genomics, metabolism, pollen dispersal and gene flow, landscape ecology, evolution, economics, technology transfer and regulatory oversight. Although the book takes its title from a Nicholas School Leadership forum held November 17-19, 2004 at Duke University, its de novo contents move past the forum’s deliberations. The result is a trans-disciplinary book composed of 14 chapters written by a total of 31 authors working in North America, South America, Europe and Africa.
Landscapes of a New Cultural Economy of Space
Aims to tie together various perspectives, insights and constructions pertaining to landscapes and landscape representations from different theoretical and methodological positions as well as from diverse geographical and historical contexts in order to elucidate and illustrate processes of cultural transformation inscribed in space.
Landscape Pattern Analysis for Assessing Ecosystem Condition
Landscape Pattern Analysis for Assessing Ecosystem Condition 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).
Landscape Ecological Applications in Man-Influenced Areas : Linking Man and Nature Systems
This book also includes several case studies concerning landscape analysis and evaluation using spatial analysis and landscape modelling for establishing sustainable management strategy in urban and agricultural landscapes. The subtitle of the book suggests the integrative and ubiquitous landscape planning considering harmony of man and nature systems in the socio-economic and cultural background.
Landscape Amenities : Economic Assessment of Agricultural Landscapes
The book mainly tries to formulate an answer to following questions: What is the economic value for society of the farmers' role as stewards of the countryside; and under which conditions are farmers willing to provide these landscape amenities? The challenge of this research is to value the agricultural landscape, as a non-commodity output from agriculture, both from a supply and demand perspective.
Lamto : Structure, Functioning, and Dynamics of a Savanna Ecosystem
Known as "a dream place for scientists," the Lamto savannas, located on the edge of the Cote d'Ivoire rain forests, are one of the only savannas in the world where ongoing ecological research has endured for more than forty years. Drawing from and synthesizing this abundance of research, the book examines the structure, functioning, and dynamics of the Lamto humid savanna. Beginning with the history of the Lamto ecology station and an overview of the major environmental conditions of the site, this exacting work specifically examines the integrative view of energy and nutrient fluxes relative to the dynamics of the savanna's vegetation.
Lake Verevi, Estonia : A highly stratified hypertrophic lake
The present book summarises investigations on Lake Verevi (surface 12.6 ha, mean depth 3.6 m). The seventeen articles in this issue deal with a wide range of questions, starting with a holistic overview of the ecological status, over assessments of long-term changes in biotic and abiotic conditions and finishing with proposed restoration plans. Abiotic chapters provide calculations on water and mass balance, distribution and fractions of phosphorus in the sediment, optical properties and penetration of radiation in the water column, sedimentation rate during the formation of stratification, and nitrogen circulation characteristics.
Lake Taihu, China : Dynamics and Environmental Change
There are many shallow lakes in the world. Many of them play an important socio-economic role as contributors to the drinking water supply, in flood attenuation, fisheries and recreation activities. Because of the current anthropogenic changes in the environment, such lakes rapidly respond to eutrophication and swamping. It is often hard to address these issues because many changes in the ecosystems of shallow lakes are associated with little studied physical processes. This interaction between the aquatic biota and the physical and chemical environment increases the complexity of shallow lake ecosystems. Lake Taihu, located in the delta of Yangtze River, is a typical large, shallow eutrophic lake with area of 2338 km2 and maximum depth of less than 3m . This book provides basic data on various aspects of this lake and summarizes research work on the interaction between its ecology and physical limnology. It will be a reference for teachers and students of freshwater ecology and biology, the aquatic environment in general, and, most strikingly, for all those interested in physical limnology.

Lagomorph Biology : Evolution, Ecology, and Conservation
Lagomorphs are a mammalian order which includes rabbits, hares and pikas. They are distributed throughout the world and are of both scientific and public interest as they are classified between endangered and pest species. In addition, some have a high economic value as important game species. In the last few decades, a huge amount of information was made available to the scientific community and resulted in remarkable advances on all aspects of Lagomorph biology. However, this information is dispersed in multiple scientific and non-scientific journals. This book provides an updated synthesis of the current knowledge on Lagomorph biology.
