Ecological Systems of the Geobiosphere

3 Temperate and Polar Zonobiomes of Northern Eurasia

By: Heinrich Walter,Siegmar-W. Breckle

By the end of the last century, the only region in all of Europe where the natural vegetation remained untouched over large expanses was Eastern Europe. Information on the vegetation of this region however, remained mostly unavailable to western scientists although the ecological approach to botanical research originated in Eastern Europe. Heinrich Walter was born in Russia, studied Natural Sciences - with emphasis on botany - in Odessa and is familiar with all relevant Russian literature on ecology. This volume thus offers scientists worldwide a unique and comprehensive survey of all relevant research, including the mostly unknown literature published in Russian.

Forestry Camp: Guide and Practical

By: Affendy Hassan,Andy Russel Mojiol,Walter J. Lintangah,Wilter Azwal

Universiti Malaysia Sabah (UMS) through the Faculty of Tropical Forestry (formerly known as School of InternationalTropical Forestry) have conducted forestry camp in the Forestry education curriculum since it was introduced in 2000. Every year, we bring the students sometimes two troops in a year to train them as a forester. At the same time, the lecturers and staff prepare the teaching materials and equipment needed for the camp, and of course, we teach them relatively similar content every year by the respective lecturer or expert with staff assistance. Indeed, writing this book is not an easy job when we have so many ideas but quite challenging to transform in a book due to time constraints and other commitments by the lecturers for many years. However, we got the motivation that we want the best for our students and we have experience in coordinating forest camps for many years. Therefore, we wrote this book to provide a guide and practical to the students about forestry camp for learning, forest mentoring, both theoretical and practical as a compliment in achieving forester values in the related forestry discipline, hard skills as well as soft skills. More than that, this book is also intended to reach a broad audience on basic knowledge about how to survive in the forest, introduction on some wild edible plant and non-forest resources, birds, wildlife, forest recreation as well as camping hazard management for those people who are intended for organizing camping in the forest. We hope that this publication provides invaluable insights that may help not only forestry students but also the people who love and enjoy the forest.

Principles of Plant Physiology

By: Walter Stiles

The book principles of plant physiology will be found particularly useful to University students reading for pass or honours degrees. For the benefit of the latter and of others who desire to read further on the subjects dealt with, references to monographs on the respective subjects are given at the ends of some of the chapters. In addition a bibliography is appended of works cited in the text. It is hoped this will be found useful to those students who wish to obtain detailed information from the original sources.

Molecular Physiology and Evolution of Insect Digestive Systems

By: Walter R. Terra,Clelia Ferreira,Carlos P. Silva

This book provides a unique blend of data on insect life spans, physiology, enzymology and other molecular features associated with digestion and nutrient absorption to enrich the knowledge on insects and to disclose putative molecular targets for the development of new insect control technologies and for improving insect raising procedures to be used as food and feed. With this aim, the book overviews the types of diets consumed by insects, describing their chemical components demanding digestion and discusses the evolutionary selective pressures on insects associated with feeding. Digestive enzymes are classified and detailed according to their activity on substrates and their evolutionary protein families. The technical details on how to obtain reliable enzymological parameters are discussed. The book reviews the structural changes in enzymes associated with the adaptation of insects to new diets and in avoiding natural plant inhibitors. Midgut features that enhance digestive and nutrient absorption efficiency and their underlying molecular mechanisms are described regarding insects pertaining to key points in evolution. Evolutionary trends of the mechanisms of digestion and nutrient absorption are discussed.

Mites: Ecology, Evolution & Behaviour

Life at a Microscale

By: David Evans Walter,Heather C. Proctor

More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.
