Marine, Freshwater, and Wetlands Biodiversity
Marine, coastal and wetland habitats are threatened, not only through exploitation, but also by the prospect of climate change – as ocean currents change course, sea levels rise, and rainfall patterns change. Even the once-common cod is now under threat from the combined effects of over-fishing and a dramatic change-induced decrease in the plankton that cod larvae feed on. Meanwhile, coral reefs remain especially vulnerable to rapid sea-level changes exacerbated by the effects of tourism and disease. This book gathers together a wide range of papers reporting on key research into the biodiversity conservation of these critical and increasingly threatened habitats. Collectively these papers provide a snap-shot of the types of problems they are experiencing, and offer a wealth of topical examples which render this volume especially valuable to teachers of courses in marine, freshwater and wetlands ecology, biological conservation and ecological restoration.
Marine Biodiversity : Patterns and Processes, Assessment, Threats, Management and Conservation
Understanding the functioning of Marine Ecosystems is the first step to measure and predict the influence of Man, and to find solutions for the enormous array of problems we face today. This volume is organised according to the four subthemes of the symposium and to issues commonly perceived as relevant by scientists concerned with the study, protection and management of Marine Biodiversity: patterns and processes, assessment, threats and management and conservation.
Marine Anthropogenic Litter
This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats.
Manual of intracytoplasmic sperm injection in human assisted reproduction
For around half of the couples who have trouble conceiving the cause of infertility is sperm-related. Intracytoplasmic sperm injection (ICSI) is the most common and successful treatment for male infertility. Here, the pioneers for the technique, along with authorities in the field, describe the underlying science of ICSI and other micromanipulation techniques. Practical advice for performing the techniques is covered in depth, including sperm selection, laser-assisted ICSI, and the use of piezo in ICSI. Examining the safety of ICSI in animal models as well as the impact of ICSI on the health and well-being of the children conceived through the procedure is discussed. This manual is an essential resource for clinical embryologists and laboratory personnel wishing to refine or develop techniques and improve outcomes.
Low-Dose Radiation Effects on Animals and Ecosystems : Long-Term Study on the Fukushima Nuclear Accident
Brings together the works of radiation biologists and ecologists to provide reliable radioecology data and gives insight into future radioprotection. The book examines the environmental pollution and radiation exposure, and contains valuable data from abandoned livestock in the ex-evacuation zone and from wild animals including invertebrates and vertebrates, aqueous and terrestrial animals, and plants that are subjected to long-term exposure in the area still affected by radiation. It also analyzes dose evaluation, and offers new perspectives gained from the accident, as well as an overview for future studies to promote radioprotection of humans and the ecosystem.
Long-Term Ecosystem Changes in Riparian Forests
Presents and analyzes the results of more than 30 years of long-term ecological research in riparian forest ecosystems with the aim of casting light on changes in the dynamics of riparian forests over time.
Living Rivers : Trends and Challenges in Science and Management
All over the world, sustainable river basin management is a leading principle of policy plans and legal instruments for water management (e.g. the European Water Framework Directive). The evidence, however, to underpin the full scope of sustainability is rather scanty. In this book an integrative perspective on trends and challenges in river science and management is demonstrated. The three pillars underneath sustainable water management, ecology, economy and sociology, are elaborated by experts in their fields. A number of papers integrate the current knowledge on the structure, functioning and management of ‘living rivers’. The book includes data and experiences concerning the rivers Allier, Meuse, Rhine, Sava and Tagliamento in Europe and the river Illinois in the USA. Sustainable river basin management asks for un-orthodox rehabilitation programmes and ecosystem based and transboundary management approaches.
Linking Restoration and Ecological Succession
Recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration and argues that restoration within a successional context will best utilize the lessons from each of these disciplines.
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.
Les infections urinaires = Urinary tract infections
Les Infections urinaires provides an update on knowledge concerning the epidemiology of community-based infection, on the mechanisms of bacterial resistance and on certain aspects of the disease useful to urologists as well as infectious diseases, gynecologists, emergency physicians and attending physicians. . Nosocomial urinary tract infection is approached from the perspective of risk factors. Acute and chronic prostatitis was the subject of a consensus conference supported by the World Health Organization within the framework of the International Consensus Conferences in Urology in Paris. The full text and the recommendations are reported with the consent of their authors. This book is an author's book and not an author's book because urinary tract infection is multiple, complex and justifies a multidisciplinary approach.
Lentil : An ancient crop for modern times
Presents the most comprehensive and up to date review of research on lentil production systems, biotic and abiotic stresses management, quality seed production, storage techniques and lentil growing around the world. This book will be of great value to legume breeders, scientists, nutritionists, academic
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.
Le Distilbène trente ans après : Les enfants des 2èmes et 3èmes générations = Distilbene thirty years later : The children of the 2nd and 3rd generations
The various consequences on the anatomy and physiology of the female genitalia, as well as male, of children exposed in utero are reviewed. The impact on girls is greater than on boys: modification of the uterine cervix, reduction in the volume of the uterus with its consequences on fertility and the progress of pregnancies, risk of cancer of the vagina and the cervix. . The potential repercussions on the third generation are analyzed from experimental studies. Finally, the medico-legal implication is studied from the various trials that took place in the United States and from the first French trial that took place in Nanterre in November 2003. This work is the result of the collaboration of several experts recognized for their competence in this field. It will be of interest to all obstetrician gynecologists, urologists, but also public health physicians and midwives.
Le dépistage du cancer du col de lutérus = Cervical cancer screening
Each year, cervical cancer kills approximately 1,000 people in France, making it the fifth leading cause of cancer death and the eighth most common cancer among women. While eradicating cervical cancer is not possible, a national screening campaign should significantly reduce its incidence. This campaign should be based, in particular, on the systematic use of Pap smears. Conventional Pap smears have already reduced the number of invasive cancers by more than 50%. Improving them requires optimizing their sensitivity. This book details the natural history of cervical cancer, its incidence and mortality, and the various aspects of screening: general principles, the French screening program, the different types of Pap smears, the role and contribution of the HPV test, the management of abnormal Pap smears, the role of colposcopy, and the follow-up of treated women. It is intended for all those involved in this screening : specialist interns and gynecologists, pathologists and biologists, public health physicians, but also general practitioners whose role in screening is privileged since they are at the forefront of medical demand.
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.
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 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.
