Book Description
r-------------{ Environment (Disease) Fig. 1. A schematic presentation of the interplay between the external environment, pathogen and animal, which influences resistance to infectious disease. Disturbance in equilibrium results in infection and disease skin and the mucous membranes of the respiratory tract. These tissues are in contact with the environment, and direct injury to them facilitate entry of pathogenic microorganisms through these important natural barriers. Sunburn and frostbite are examples of such adverse effects. Climatic factors such as heat and cold may also act as physiological stress factors which affect the specific and non-specific responses of the body to infection. 1.1.2 Pathogen Survival Climatic factors may affect dispersal, spread and survival of pathogenic micro organisms in the environment. This is also true for arthropod vectors such as mosquitos and ticks (Smith 1970; Ferguson and Branagan 1972). The density of the animal population is an important factor determining the concentration of patho gens in the environment. Population density can be influenced by weather condi tions, as animals respond to heat and cold by typical changes in behaviour. For example, in cold weather they tend to huddle together. This behaviour results in increased population density, which in turn involves an increased risk of the spread of airborne infections.

Book Description
Atmospheric carbon dioxide concentration has increased globally from about 280 ppm before the Industrial Revolution (Pearman 1988) to about 353 ppm in 1990. That increase, and the continuing increase at a rate of about 1.5 ppm per annum, owing mainly to fossil fuel burning, is likely to cause change in climate, in primary productivity of terrestrial vegetation (managed and unmanaged), and in the degree of net sequestration of atmospheric CO into organic form. The quantitative role 2 of the latter in attenuating the increase in atmospheric CO concentration itself is 2 an important but uncertain element of the global carbon-cycle models that are required to predict future increases of atmospheric CO concentration. 2 In my experience in workshops and other multidisciplinary gatherings, argument arises in discussion of this topic among different groups of scientists such as bioclimatologists, plant physiologists, biogeochemists and ecologists. Plant concentration physiologists are often impressed by the positive effect of higher CO 2 on plant growth under experimental controlled environments and argue that this would be at least partly expressed in the field for many species and communities.

Book Description
Presenting the latest research on the effects of cold and sub-zero temperatures on plant distribution, growth and yield, this comprehensive volume contains 28 chapters by international experts covering basic molecular science to broad ecological studies on the impact of global warming, and an industry perspective on transgenic approaches to abiotic stress tolerance. With a focus on integrating molecular studies in the laboratory with field research and physiological studies of whole plants in their natural environments, this book covers plant physiology, production, development, agronomy, ecology, breeding and genetics, and their applications in agriculture and horticulture.

Book Description
This book focuses on various psycho-social and socio-physical aspects of climate change and includes a wide range of case studies. Included topics are notable climate-related social thinking; climate vulnerability; transformation in socio-ecological subsystems; bioclimatological, urban bioclimatological and socio-bioclimatic ideas; disasters; policy instruments; climate justice; human rights; and sustainability. The book distinguishes itself from similar works by including a wide variety of topics and assists policy management in the current and upcoming climate crisis era. This book also addresses the Sustainable Development Goals 13 (Take Urgent Action to Combat Climate Change and Its Impacts), highlighting resilience, recovery potential and adaptive capacity, climate change measures integrated into policies and planning, and knowledge and capacity to mitigate climate change. The ideas covered in this book evolved in response to the current climate crisis, ideas that the authors believe will aid in societal management and development in the present and future. The book is a useful source for planners, geographers, professionals, academics, government officials, laypeople, and others interested in climate change.
