A richly illustrated guide to the astonishing variety of beetles around the world Beetles make up about a quarter of known animal species and are arguably the most diverse group of organisms on Earth: almost 400,000 species have been formally described so far, and it is likely that this number merely scratches the surface. In Beetles of the World, Maxwell Barclay and Patrice Bouchard—two of the world’s foremost beetle experts—celebrate these remarkable creatures in all their variety, from their size and appearance to their ecological importance. Providing concise accounts of all the major families and subfamilies of Coleoptera, Beetles of the World explores beetle anatomy, life cycle, fossil history, feeding habits, role in the food web, habitats, relationship with humans, and classification—as well as the essential part that beetles play in the global ecosystem, and the ways humans can help protect them. Features 300 stunning color photographs Presents family profiles with a distribution map, table of information, and commentary Includes a comprehensive introduction that provides insight into the astonishing diversity of beetles and their histories

This book comprehensively reviews current pest management practices and explores novel integrated pest management strategies in Brassica oilseed crops. It is essential reading for pest management practitioners and researchers working on pest management in canola and other Brassica crops worldwide. Canola, mustard, camelina and crambe are the most important oilseed crops in the world. Canola is the second largest oilseed crop in the world providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals with 35 to 40% protein. However, its production has declined significantly in recent years due to insect pest problems. The canola pest complexes are responsible for high insecticide applications on canola. Many growers rely on calendar-based spraying schedules for insecticide applications. The diamondback moth Plutella xylostella and flea beetles Phyllotreta spp. (P. cruciferae and P. striolata)cause serious damage to canola. In the Northern Great Plains, USA, for instance, P. xylostella is now recorded everywhere that canola is grown. Severe damage to canola plants can be caused by overwintering populations of flea beetles feeding on newly emerged seedlings. Cabbage seed pod weevil (Ceutorhynchus obstrictus), swede midge (Contarinia nasturtii), and tarnished plant bug (Lygus lineolaris) are also severe pests on canola. Minor pests include aphids (cabbage aphid, Brevicoryne brassicae and turnip aphid, Hyadaphis erysimi) and grasshopper, Melanoplus sanguinipes.

With perhaps 8,000 different species, beetles are easily the largest group of animals in California and can be found virtually everywhere in the state. They grapple over flower heads, lurk in pantries, paddle through pristine mountain streams, amble over dunes, and buzz about porch lights on warm evenings. But until now, there was no single resource for identifying the most commonly encountered beetles in California’s mountains, valleys, and deserts. This valuable field guide, a companion volume to Introduction to California Beetles published in 2004, identifies more than 500 of the state’s more conspicuous and colorful species, with the majority presented in stunning color photographs. Written and designed for amateur naturalists, students, and field biologists, it is chock-full of what every beetle watcher wants to know, including suggestions for finding beetles, starting a beetle collection, and keeping beetles in captivity. The informative, accessibly written species accounts include information on beetle identification, natural history, and distribution. * Features 300 color photographs, 110 drawings, and 2 maps * Covers 569 species in 56 families * Lists California’s sensitive, threatened, and endangered species * Provides resources and web sites for further study of California beetles

The Ancient Human Occupation of Britain Project (AHOB) funded by the Leverhulme Trust began in 2001 and brought together researchers from a range of disciplines with the aim of investigating the record of human presence in Britain from the earliest occupation until the end of the last Ice Age, about 12,000 years ago. Study of changes in climate, landscape and biota over the last million years provides the environmental backdrop to understanding human presence and absence together with the development of new technologies. This book brings together the multidisciplinary work of the project. The chapters present the results of new fieldwork and research on old sites from museum collections using an array of new analytical techniques. Features an up-to-date treatment of the record of human presence in the British Isles during the Palaeolithic period (700,000 - 10,000 years before present) Takes multidisciplinary approach that includes archaeology, geochemistry, geochronology, stratigraphy and sedimentology Coincides with the culmination of the AHOB project in 2010, providing a benchmark statement on the record of human occupation in Britain that can be utilized and tested by future research

Offering a complete accounting of the insects of North America, this handbook is an up-dated edition of the first handbook ever compiled in the history of American entomology. By using American Insects, A Handbook of the Insects of America North of Mexico, Second Edition, readers can quickly determine the taxonomic position of any species, genus, or higher taxon of insect known to occur in America and Canada. Every order, family, and genus is conveniently numbered and indexed, making this volume the only complete single source for all of the names of orders, families, and genera currently available. This book fills the need for an accurate way to identify, with the several hundred drawings and photos, the common insects of all orders. Now there is a tool available to those working without a major collection and library; and those who would like to have a general knowledge of insect life without becoming overwhelmed by the vast number of minute insect species. This usable guide provides sizes, shapes, color patterns and salient features of some species of each major family by pointing out those groups most likely to be encountered, including all North America pests. What's New in this Edition? Researchers in many orders use the results of cladistics, a new tool for determining the relationship of orders, families, genera, and species of organisms, including plants as well as animals Specialists have provided lengthy lists of generic changes Many of the identification keys have been revised by adding more illustrations and making sure all description terms are in the Glossary The bibliographies of each Order section have been updated to include all important works that have appeared since the original edition

Pollination and Floral Ecology is the most comprehensive single-volume reference to all aspects of pollination biology--and the first fully up-to-date resource of its kind to appear in decades. This beautifully illustrated book describes how flowers use colors, shapes, and scents to advertise themselves; how they offer pollen and nectar as rewards; and how they share complex interactions with beetles, birds, bats, bees, and other creatures. The ecology of these interactions is covered in depth, including the timing and patterning of flowering, competition among flowering plants to attract certain visitors and deter others, and the many ways plants and animals can cheat each other. Pollination and Floral Ecology pays special attention to the prevalence of specialization and generalization in animal-flower interactions, and examines how a lack of distinction between casual visitors and true pollinators can produce misleading conclusions about flower evolution and animal-flower mutualism. This one-of-a-kind reference also gives insights into the vital pollination services that animals provide to crops and native flora, and sets these issues in the context of today's global pollination crisis. Provides the most up-to-date resource on pollination and floral ecology Describes flower advertising features and rewards, foraging and learning by flower-visiting animals, behaviors of generalist and specialist pollinators--and more Examines the ecology and evolution of animal-flower interactions, from the molecular to macroevolutionary scale Features hundreds of color and black-and-white illustrations
