Описание: Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.
Описание: The first volume of the Integrated Management of Plant Pests and Diseases book series presents general concepts on integrated pest and disease management, organized in three sections. Section one (modeling, management, environment) includes chapters on infection models, resurgence and replacement, plant disease epidemiology and effects of climate change in tropical environments. Followed by two reviews on IPM in post-harvest and carrot crops. The second section (emerging technologies) includes remote sensing and information technology, integrated by reviews on Bacillus thuringiensis and the role of mycorrhizae in IPM. In the third section (molecular aspects) the management of insect-borne viruses with transmission interference, some novel products for biological control and advances in molecular detection, are discussed.
Описание: This book integrates and systematically assesses China`s ecological restoration programs. It covers a range of topics from land use change, carbon/erosion dynamics to income/employment effects.

Описание: To demonstrate the connection between academic neuroanatomy and the practice of clinical neurology, this innovative textbook presents carefully chosen clinical cases that illustrate how the nervous system is constructed and how it functions under normal circumstances. Providing the foundation needed to encounter neurological diseases, it teaches students and residents how to integrate a patient?s clinical history and examination with neuroanatomy. In addition to color illustrations throughout, the book adds an invaluable DVD for further exploration and access to a state-of-the-art website with additional materials that are updated periodically.

Описание: The Long-Term Ecological Research (LTER) Program is, in a sense, an experiment to transform the nature of science, and represents one of the most effective mechanisms for catalyzing comprehensive site-based research that is collaborative, multidisciplinary, and long-term in nature. The scientific contributions of the Program are prodigious, but the broader impacts of participation have not been examined in a formal way. This book captures the consequences of participation in the Program on the perspectives, attitudes, and practices of environmental scientists. The edited volume comprises three sections. The first section includes two chapters that provide an overview of the history, goals, mission, and inner workings of the LTER network of sites. The second section comprises three dozen retrospective essays by scientists, data managers or educators who represent a broad spectrum of LTER sites from deserts to tropical forests and from arctic to marine ecosystems. Each essay addresses the same series of probing questions to uncover the extent to which participation has affected the ways that scientists conduct research, educate students, or provide outreach to the public. The final section encompasses 5 chapters, whose authors are biophysical scientists, historians, behavioral scientists, or social scientists. This section analyzes, integrates, or synthesizes the content of the previous chapters from multiple perspectives and uncovers emergent themes and future directions.
Описание: Presents 20 years of work at the North Temperate Lakes Long-Term Research Site. This site-synthesis volume provides the information base for the ecology of temperate lakes, and a general assessment of the role of lakes within their landscapes. It is of interest to American limonologists and general ecologists.
