Principles and Practices in Plant Ecology: Allelochemical Interactions provides insights and details recent progress about allelochemical research from the ecosystem standpoint. Research on chemical ecology of allelochemicals in the last three decades has established this field as a mature science that interrelates the research of biologists, weed and crop scientists, agronomists, natural product chemists, microbiologists, ecologists, soil scientists, and plant physiologists and pathologists. This book demonstrates how the influence of allelochemicals on the various components of an ecosystem-including soil microbial ecology, soil nutrients, and physical, chemical, and biological soil factors-may affect growth, distribution, and survival of plant species. Internationally renowned exper†s discuss how a better understanding of allelochemical phenomena can lead to true sustainable agriculture.

A daring rescue in the middle of a snowstorm in this compelling Red Fox Road companion survival story for ages 10 to 14, for fans of Hatchet and The Skeleton Tree. After a family trip turned disastrous when their truck broke down in the middle of an old logging road in Oregon, Francie is now back in British Columbia. People try to make things as "normal" as possible for her, but they don't understand that trying to be normal in your old life that's exploded is the worst feeling in the world. Luckily for Francie, the wilderness is still soothing, and an opportunity to attend the Green Mountain Academy, a tiny boarding school perched on the side of a mountain, seems perfect. It's a new start, with new friends and a chance at a new family. But when a winter storm hits, knocking out all the power, news that a small plane has gone missing unsettles Francie. Knowing that the chance of survival in the middle of a wild nighttime snowstorm diminishes over time, Francie is compelled to leave the cozy school and set out into the icy cold, swirling snowstorm . . .

This book is about desertification. The author describes vegetation degradation as a part of the integral process of desert ecosystem degradation in Central Asia under the impact of human activities. A connection is made between political and social factors and degradation of desert environments in historical perspective. Fragile desert ecosystems suffer first of all from the loss of vegetation. Wildlife is reduced, productivity of desert rangelands fall and the people also suffer from a shortage of food. The after-effect of this process is catastrophic, not only for the desert itself but also for the people living in the desert. Several measures are also discussed in the book for conservation of desert vegetation and rehabilitation of desert lands.
