Terrestrial Mammal Conservation provides a thorough summary of the available scientific evidence of what is known, or not known, about the effectiveness of all of the conservation actions for wild terrestrial mammals across the world (excluding bats and primates, which are covered in separate synopses). Actions are organized into categories based on the International Union for Conservation of Nature classifications of direct threats and conservation actions. Over the course of fifteen chapters, the authors consider interventions as wide ranging as creating uncultivated margins around fields, prescribed burning, setting hunting quotas and removing non-native mammals. This book is written in an accessible style and is designed to be an invaluable resource for anyone concerned with the practical conservation of terrestrial mammals. The authors consulted an international group of terrestrial mammal experts and conservationists to produce this synopsis. Funding was provided by the MAVA Foundation, Arcadia and National Geographic Big Cats Initiative. Terrestrial Mammal Conservation is the seventeenth publication in the Conservation Evidence Series, linked to the online resource www.ConservationEvidence.com. Conservation Evidence Synopses are designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include Bat Conservation, Primate Conservation, Bird Conservation and Forest Conservation and more are in preparation. Expert assessment of the evidence summarised within synopses is provided online and within the annual publication What Works in Conservation.

This book compiles for the first time all the current information on the electronic monitoring of the feeding behavior of phytophagous true bugs. It includes state-of-the-art illustrations of feeding sites on the various plant structures, and examines how the different feeding strategies are related to the variable waveforms generated using the electropenetrography (EPG) technique. Further, the book describes the mouthparts and modes of feeding and discusses the physical and chemical damage resulting from feeding activities. Covering in detail all EPG studies developed and conducted using true bugs published to date, it explores the use of electronic monitoring of feeding coupled with histological analyses to improve strategies to control true bugs, from traditional chemical methods to gene silencing (RNAi).
One of the four main Aztec crops at the time of Columbus’s arrival in the New World, chia is now a forgotten food of the Americas. Chia seed oil offers the highest omega-3 fatty acid content available from plants, but today this species is known only for its use in "chia pets." Yet pre-Columbian civilizations used chia as a raw material for medicines and nutritional compounds, while chia flour could be stored for years as a food reserve and was valued as a source of energy on long journeys. In this book, agronomist Ricardo Ayerza and agricultural engineer Wayne Coates trace the long and fascinating history of chia’s use, then reveal the scientific story of the plant and its modern potential. They compare fatty acid profiles of chia with our other major sources—fish oil, flaxseed, and marine algae—and provide evidence that chia is superior in many ways. Here are just some of the benefits that chia provides: - chia has the highest known percentage of alpha-linolenic acid, and the highest combined alpha-linolenic and linoleic fatty acid percentage of all crops - chia has more protein, lipids, energy, and fiber—but fewer carbs—than rice, barley, oats, wheat, or corn—and its protein is gluten-free - chia is an excellent source of calcium, phosphorus, magnesium, potassium, iron, zinc, and copper - chia is low in sodium: salmon has 78 times as much, tuna 237 times as much - chia exhibits no evidence of allergic response, even in individuals with peanut and tree-nut allergies - chia doesn’t give off a “fishy flavor,” unlike some other sources of omega-3 fatty acid The need to balance the essential fatty acid content of the human diet, combined with the need for a safe, renewable, omega-3 fatty acid source, positions chia to become one of the world’s important crops. As this insightful study shows, current nutritional understanding provides an excellent opportunity to reintroduce this important food to the world.
This comprehensive volume presents indispensable and up-to-date information on viroids and viroid diseases. It provides a single source of information on the properties of viroids, the economic impact of viroid diseases, and methods for their detection and control. It examines the diseases associated with different plant species, the geographic distribution and epidemiology of viroids, diseases of possible viroid etiology, and the future applications of viroids. Viroids examines the biology of viroids, molecular characteristics, localization and movement, replication, pathogenesis, viroids and gene silencing, classification, viroid-like satellite RNAs, detection of viroids using bioamplification hosts, biological indexing, polyacrylamide gel electrophoresis, molecular hybridisation and polymerase chain reaction. The book looks at the geographical distribution and epidemiology of viroids in North America, Australasia, China, Japan, Europe, the Middle East, Africa, South America, and at the global level. It covers the control of viroids including quarantine of imported germplasm, availability of viroid-tested propagation materials, thermotherapy, tissue culture, and other conventional strategies as well as biotechnological control approaches. Special topics such as ribozyme reaction of viroids and economic advantages of viroid infection are also included. Other chapters summarise the current state of knowledge concerning viroid diseases of the crop in question and aspects of the natural history of viroids in horticulture. Among the crops covered are potato, tomato, tobacco, cucumber, pome fruits, stone fruits, avocado, citrus, grapevines, hop, chrysanthemum, coleus, columnea, and coconut palm. The four eminent editors of this watershed volume have assembled an international group of more than 70 scientists who have substantial experience with viroids and viroid diseases. They have produced a cohesive and comprehensive work that can be used by students, researchers, extension agents, and regulators. It may also be of a great value to science managers, policy makers, and industries in formulating policies and products to obtain viroid-free plants and control viroid diseases. The information on plant quarantine and certification programs will help anyone concerned with the safe movement of plant material across international boundaries or within a single country.
