This text asserts that a stroke should be thought of as a syndrome, or collection of disease processes, rather than a single disease. Strokes are characterized by restriction of blood flow to the brain and are responsible for imposing a very significant burden on healthcare systems, accounting for more than four million deaths per year. They can be directly linked to the majority of adult neurological disability and they contribute to vascular dementia, the second most common cause of dementia after Alzheimer's Disease. Despite its importance on a population basis, research into the genetics of strokes has lagged behind many other disorders; however, the situation is changing and there is now growing evidence that genetic factors are important in the stroke risk, often acting via interactions with conventional risk factors.

Are humans too good at adapting to the earth’s natural environment? Every day, there is a net gain of more than 200,000 people on the planet—that’s 146 a minute. Has our explosive population growth led to the mass extinction of countless species in the earth’s plant and animal communities? Jeffrey K. McKee contends yes. The more people there are, the more we push aside wild plants and animals. In Sparing Nature, he explores the cause-and-effect relationship between these two trends, demonstrating that nature is too sparing to accommodate both a richly diverse living world and a rapidly expanding number of people. The author probes the past to find that humans and their ancestors have had negative impacts on species biodiversity for nearly two million years, and that extinction rates have accelerated since the origins of agriculture. Today entire ecosystems are in peril due to the relentless growth of the human population. McKee gives a guided tour of the interconnections within the living world to reveal the meaning and value of biodiversity, making the maze of technical research and scientific debates accessible to the general reader. Because it is clear that conservation cannot be left to the whims of changing human priorities, McKee takes the unabashedly neo-Malthusian position that the most effective measure to save earth’s biodiversity is to slow the growth of human populations. By conscientiously becoming more responsible about our reproductive habits and our impact on other living beings, we can ensure that nature’s services will make our lives not only supportable, but also sustainable for this century and beyond.

Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty.Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.

The book “Biodiversity of Wetlands and Forests: A Nature Trail” focuses on biodiversity of wetlands and forests with special emphasis on field observations of plants, reptiles, birds and mammals recorded by the author in various geographical provinces of Gujarat, India. It highlights the need of biodiversity conservation, causes and concerns, exploitation of biodiversity, habitat destruction, interaction of man and technology with biodiversity, policy framework for biodiversity conservation, and wilderness and forests. Moreover, it summarizes a review on birds with special emphasis on geographical and ecological distribution of avifauna of north-western India, birds in ancient times with myths and motifs, an integral association of trees and birds, birds migration, magnetic orientation of birds, and mythological beliefs about birds. The present book covers exhaustive information on wetlands for tourism, important wetlands of national importance, wise use, characteristics and prime importance of wetlands as enduring habitats, and threats to viable wetlands. It emphasizes significant wetlands as abode for avifauna, wetlands as bird habitats, significant factors for survival of wetland birds, importance of wetlands for birds’ population, influence of wetlands on waterfowl population, wetland loss and decline of bird diversity, threats to avian habitats, and conservation and management strategies for potential avian ecosystems and legal policy framework for sustainability of waterbirds. The book is written in articulate manner citing notable sightings of some unique floral and faunal elements in the forested pockets. It encompasses archetypal records of plants, animals and birds along with their distinctive occurrence, feeding patterns, conservation, and management of threatened biodiversity, and many more. It describes some remarkable, noteworthy and astonishing sightings of species inhabiting in potential niches, habitats and ecosystems of Western India. Here, the author has shared his incidental as well as subsisting experiences in amazing habitats amidst the nature trails of forested patches and thickets. This book will undoubtedly enrich and enhance the knowledge and awareness of naturalists in the field. This book is a blend of two previously published books by the same author (Hiren B. Soni, Ph.D.) viz. ‘Biodiversity, Birds and Wetlands’, and ‘Biodiversity and Birds: A Field Journey’. This book is published to be handy and helpful to every reader and amateur of the world. Author believes that it would surely be a ready-reference for every researcher as well as nature lover in each and every corner of the world.

Natural resources management has two principal dimensions : Science-illuminated (earth, space, hydrological, pedological, information, etc. sciences) management of local resources (waters, soils, bioresources, minerals, rocks, sediments, etc.) in an ecologically-sustainable manner, and Value-addition through processing of natural products, through the application of technology is most marked in the case of some mineral products. The wellness of a community is dependent upon the security of food, water, environment and energy. Such a security is best realised through science-illuminated (earth, space, hydrological, pedological, information) management of local resources (waters, soils, bioresources, minerals, rocks, sediments, etc.) in an ecologically-sustainable and people-participatory manner, plus value-addition through processing of natural products. Moreover, the addition of value may increase a community’s wealth by advanced technologies, trading, exchange of knowledge, etc. Moreover, activities, employment and many other things come along with the availability of natural resources, which will require and affect policy. This volume provides guidelines for the implementation of technological, economical and policy advances in dealing with various aspects of natural resources. It is intended for researchers, professionals and students in environmental and earth sciences, mining, geography, sociology, economics and for policy makers and investors searching for potential in the natural resources industry. Ideal for consultation in combination with the editor's related publications Green Energy: Technology, Economics and Policy, Energy Portfolios and Food and Water Security.
