Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Phil Lester's first book, The Vulgar Wasp, was about one of the world's most hated insects. His second is about just the opposite &– the honey bee, arguably one of our best-loved six-legged creatures. People have revered honey bees for centuries. Today we celebrate them with toys, postage stamps and campaigns to raise awareness; we dress up in large bee suits to protest the use of pesticides; we've even sent bees into space and watched as they adjusted to microgravity.Bees are one of the world's most efficient pollinators. Their work is vital to the success of many food crops, and hence to the world's economy. So we need to take seriously any threats to their health &– including parasites, pathogens, predators and pesticides &– and, guided by evidence at every turn, find a way to minimise harm and keep bees thriving. As Healthy Bee, Sick Bee shows, this is no small task.In this book, entomologist Phil Lester explores the wonderfully complex and sometimes brutally efficient life history of honey bees, and the problems they face in New Zealand and around the globe. What causes a beehive to collapse? Are pesticides as big a problem as they appear? What can we do to improve the health

This book presents comprehensive coverage on the importance of good nutrition in the treatment and management of obesity, cancer and diabetes. Naturally occurring bioactive compounds are ubiquitous in most dietary plants available to humans and provide opportunities for the management of diseases. The text provides information about the major causes of these diseases and their association with nutrition. The text also covers the role of dietary phytochemicals in drug development and their pathways. Later chapters emphasize novel bioactive compounds as anti-diabetic, anti-cancer and anti-obesity agents and describe their mechanisms to regulate cell metabolism. Written by global team of experts, Dietary Phytochemicals: A Source of Novel Bioactive Compounds for the Treatment of Obesity, Cancer and Diabetes describes the potentials of novel phytochemicals, their sources, and underlying mechanism of action. The chapters were drawn systematically and incorporated sequentially to facilitate proper understanding. This book is intended for nutritionists, physicians, medicinal chemists, drug developers in research and development, postgraduate students and scientists in area of nutrition and life sciences.

Honey Bees: Estimating the Environmental Impact of Chemicals is an updated account of the different strategies for assessing the ecotoxicity of xenobiotics against these social insects, which play a key role in both ecology and agriculture. In addition to the classical acute laboratory test, semi-field cage tests and full field funnel tests, new te

The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.
