For ecologists, stable isotopes provide a natural way to directly trace details of element cycling in the environment. This book begins by reviewing fundamental topics of tracer fractionation and mixing.

It emphasizes the role that humans increasingly play in changing our planetary ecosphere. Packed with clearly labeled, full-color drawings on every page, Atlas of Middle Ear Surgery guides readers through the most common and innovative surgical procedures used to manage middle ear pathology.

The authors, experts in this technically demanding field, begin by providing practical background information on surgical anatomy and pathophysiology followed by a brief introduction to anesthesia considerations and operating room etiquette. Full-color drawings then demonstrate the various surgical techniques in a step-by-step formatthat is excellent for learning.

Succinct, easy-to-understand descriptions accompany every drawing in a didactic manner that reinforces fundamental concepts as it teaches. Features- The latest on the surgical management of tympanic membrane abnormalities, chronic otitis media, cholesteatoma, and ossicular chain dysfunction- full-color drawings and schematics display anatomy and important surgical steps- Numerous callout boxes in each chapter highlight key surgical tips, pearls, and pitfallsConcise and practical, this atlas is essential reading for otolaryngology residents, fellows, budding otologic surgeons, or practicing ENTs who need to hone their surgical skills and stay abreast of the latest advances in the field.

An exploration of the production, transmission, and mutation of affective tonality--when sound helps produce a bad vibe. Marine Historical Ecology in Conservation: Provides a blueprint for managing the challenges of ocean conservation using marine historical ecology an interdisciplinary area of study that is helping society to gain a more understanding of past human-environmental interactions in coastal and marine ecosystems and of the ecological and social outcomes associated with these interactions.

Food security and environmental conservation are two of the greatest challenges facing the world today. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources.

The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues.

Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists. New gene-based technologies can now be employed to examine microbial diversity through the use of small sub-unit ribosomal DNA analysis e. These technologies have the potential to revolutionize the understanding of rumen function and will overcome the limitations of classical based techniques, including isolation and taxonomic identification of strains important to efficient rumen function and better understanding of the roles of microorganisms in relation to achieving high productivity and decreasing environmental pollutants.

This book presents a comprehensive up-to-date account of the methodologies and protocols for conventional and modern molecular techniques that are currently in use for studying the gut microbial ecology of ruminants. Each chapter has been contributed by experts in the field and methods have been presented in a recipe-like format designed for direct practical use in the laboratory and also to provide insight into the most appropriate techniques, their applications and the type of information that could be expected.

The techniques and procedures described are also relevant and adaptable to other gastrointestinal ecosystems and the microbiology of anaerobic environments in general. This book attempts to bridge the gap between ecology and natural resource management and in particular, focuses on the discipline of plant ecology as a foundation for vegetation and wildlife management.

It describes how concepts and approaches used by ecologists to study communities and ecosystems can be applied to their management.

McPherson and Stephen DeStefano emphasise the importance of thoughtfully designed and carefully conducted scientific studies to both the advancement of ecological knowledge and the application of techniques for the management of plant and animal populations.

The book is aimed at natural resource managers, as well as graduate and advanced undergraduate students, who are familiar with fundamental ecological principles and who want to use ecological knowledge as a basis for the management of ecosystems. ООО "Логосфера " Тел:
