Различные книги в жанре БиологияThe Great Alaska Nature Factbook
This guidebook is organized into three easy-to-read sections: animals, plants, and the natural features of Alaska which is the largest and most varied of all the states in America. Entries in each section are listed alphabetically. This book contains fascinating factoids, line art drawings, and a state map along with entertainingly written entries. Whether you live in Alaska or are just passing through, you’ll discover a gold mine of nuggets, facts, and information that will give you a deeper understanding about everything you may encounter from reindeer, puffins, and Dall sheep to taiga, pingos, and fjords.
Alaska's Wilderness Medicines
This guide to Alaskan wild plants, native and introduced, can be used to promote health and healing, use for emergency first-aid care, or to maintain wellness. More than fifty plant species are described with information on habitat and distribution as well as general information on how each one can be used as medicine. This natural history of some of Alaska’s medicinal plants is not intended to serve the purpose of a self-care manual of medicine. Dr. Eleanor G. Viereck presents useful and fascinating information about trees, flowers, and shrubs accompanied by accurately rendered line drawing of the vegetation.
Life Rules
Corporate capitalism has ravaged the planet the same way HIV ravages the human body, triggering a critical mass of cascading environmental, economic, social, and political crises. Economic and climate instability, collapsing ecosystems, peak fossil fuels, and devastating resource wars—if the Earth were a patient, her condition would be critical. Life Rules offers a comprehensive analysis of our present circumstances, combined with a holistic treatment protocol for restoring health to vulnerable human and natural communities. Predicting that Life will last, but if we don't make some fundamental changes, life as we know it—and a lot of us—won't, Life Rules identifies natural laws that have allowed non-human communities to thrive and prosper for several billion years, including: Local self-reliance Mutual interdependence Reliance on non-fossil sources of energy Resource conservation, sharing, and recycling Radically democratic self-organization and governance This sobering yet essentially optimistic manifesto is required reading for anyone concerned about our ability to live within Earth's means. A powerful tool for community transition and cultural transformation, Life Rules offers a solution to our global challenges that is at once authentically hopeful, deeply inspiring, and profoundly liberating. Ellen LaConte is acting director of the EarthWalk Alliance, a contributing editor to Green Horizon Magazine and The Ecozoic, a frequent talk show guest, and publisher of the Starting Point online newsletter. She has written two books about Helen and Scott Nearing, homesteaders and best-selling authors of Living the Good Life, and she is the author of the upcoming environmental novel Afton.

Potato
Potatoes are a staple crop around the world. Covering all aspects of botany, production and uses, this book presents a comprehensive discussion of the most important topics for potato researchers and professionals. It assesses the latest research on plant growth such as tuber development, water use and seed production, covers all aspects of pest management and reviews postharvest issues such as storage, global markets, and of course, nutritional value and flavour.
Genetics of Cattle, The
Since the time of domestication more than 10,000 years ago, cattle have played an increasingly crucial role in the development of human civilizations. Progress has been quite remarkable since the turn of the century; the sequencing of the bovine genome in 2009 launched new avenues for furthering our understanding of theoretical and practical aspects of cattle genetics.
Covering a vast array of questions, this book reviews major topics from molecular and developmental genetics, disease resistance and immunogenetics to genetic improvement of dairy and beef breeds, addressing all current problems in the field. This second edition includes a new team of authors and completely new chapters on the genetics of fat production, nutrition, feed intake and efficiency, growth and body composition. Fully updated throughout, it provides a valuable resource on cattle genetics for researchers, breeders, veterinarians and postgraduate students.
Global Forest Fragmentation
Forest fragmentation will inevitably continue over the coming years, especially in developing economies. This book provides a cutting edge review of the multi-disciplinary sciences related to studies of global forest fragmentation. It specifically addresses cross-cutting themes from both an ecological and a social sciences perspective. The ultimate goal of Global Forest Fragmentation is to provide a detailed scientific base to support future forest landscape management and planning to meet global environmental and societal needs.
Invasive Species and Global Climate Change
This book examines what will happen to global invasive species, including plants, animals and pathogens with current and expected man-made climate change. The effects on distribution, success, spread and impact of invasive species are considered for a series of case studies from a number of countries. This book will be of great value to researchers, policymakers and industry in responding to changing management needs.
Livestock Handling and Transport
Edited by world-renowned animal scientist Dr. Temple Grandin, this practical book integrates scientific research and industry literature on cattle, pigs, poultry, sheep, goats, deer, and horses, in both the developed and developing world, to provide a practical guide to humane handling and minimizing animal stress. Reviewing the latest research on transport systems, restraint methods and facilities for farms and slaughterhouses, this fully updated fourth edition of Livestock Handling and Transport includes new coverage of animal handling in South America, and reviews extensive new research on pig transportation in North America.
Fruit Ripening
Fruit ripening is an important aspect of fruit production. The timing of it affects supply chains and buying behaviour, and for consumers ripeness not only affects perceptions of health but has nutritional effects too. Ripeness is closely related to spoilage which has a major financial impact on agricultural industries. Currently there are fast moving developments in knowledge of the factors affecting fruit ripeness, and this up-to-date monograph seeks to draw together the disparate research in this area. The aim of the book is to produce a comprehensive account covering almost every area related to fruit ripening including the latest molecular mechanisms regulating fruit ripening, its impact on human nutrition and emerging research and technologies.
