Available in PDF, EPUB and Kindle. Book excerpt: Based on papers presented at a 1987 symposium, "Fire in North American Grasslands," cosponsored by the Ecological Society of America and the Botanical Society of America, this book represents an important contribution to key unanswered questions concerning the role of fire in grassland ecosystems: How often did fires occur in the past? Were they primarily natural or caused by humans? At what time of year did grasslands normally burn? How should fire be used as a management tool? What constitutes a proper prescribed burning regime both with and without grazing?
Download or read book The Butterflies of Canada written by Ross Layberry and published by University of Toronto Press. This book was released on 1998-12-15 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beautifully illustrated and clearly presented, The Butterflies of Canada is an indispensable guide to all aspects of butterfly study. Butterfly collecting has long been a popular summer activity, and as the growing popularity of butterfly watching and conservatories in Ontario and British Columbia shows, butterflies are a continuing source of delight and interest to Canadians. The Butterflies of Canada is the first comprehensive guide to all the butterflies found in Canada. Based on the national butterfly collection maintained by Agriculture and Agri-Food Canada, it contains descriptive individual accounts for the close to three hundred butterfly species recorded in Canada, including descriptions of early stages, subspecies, and key features that help distinguish similar species. Each species of butterfly has an individual distribution map, generated from a database of more than 90,000 location records. More than just a field guide to identifying Canadian butterflies, however, The Butterflies of Canada includes chapters on Canadian geography and butterfly distribution, conservation, gardening, photography, and the history of butterfly study in Canada. It also contains new and unpublished information on the classification of butterflies, their ranges, larval food plants, abundance, flight seasons, and noteworthy habits. Thirty two colour plates provide diagnostic details for each species, and also feature butterflies in their natural habitats. There is an extensive bibliography.

Now fully updated with new sections addressing current research and new developments, such as the metapopulation concept of understanding butterfly populations and their management, this new edition of Butterfly Conservation provides a broad survey of the science of butterfly conservation. The book introduces butterfly classification and biology, and then goes on to discuss the causes of declining butterfly populations and current attempts to conserve particular species. This book will be important reading for all entomologists, naturalists, and conservationists.
Download or read book The Solitary Bees written by Bryan N. Danforth and published by Princeton University Press. This book was released on 2019-08-27 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most up-to-date and authoritative resource on the biology and evolution of solitary bees While social bees such as honey bees and bumble bees are familiar to most people, they comprise less than 10 percent of all bee species in the world. The vast majority of bees lead solitary lives, surviving without the help of a hive and using their own resources to fend off danger and protect their offspring. This book draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects. The Solitary Bees uses a modern phylogenetic framework to shed new light on the life histories and evolution of solitary bees. It explains the foraging behavior of solitary bees, their development, and competitive mating tactics. The book describes how they construct complex nests using an amazing variety of substrates and materials, and how solitary bees have co-opted beneficial mites, nematodes, and fungi to provide safe environments for their brood. It looks at how they have evolved intimate partnerships with flowering plants and examines their associations with predators, parasites, microbes, and other bees. This up-to-date synthesis of solitary bee biology is an essential resource for students and researchers, one that paves the way for future scholarship on the subject. Beautifully illustrated throughout, The Solitary Bees also documents the critical role solitary bees play as crop pollinators, and raises awareness of the dire threats they face, from habitat loss and climate change to pesticides, pathogens, parasites, and invasive species.

Download or read book Volume 1 Evolution Systematics and Biogeography written by Niels P. Kristensen and published by Walter de Gruyter. This book was released on 1998-12-03 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: The renowned German reference work The Handbuch der Zoologie/Handbook of Zoology was founded in the 1920's by Professor Willi Kükenthal in Berlin and treated the complete animal kingdom from single cell organisms to mammals in eight thematic volumes: Volume I Protozoa, Porifera, Colenteratea, Mesozoa (1925); Volume II Worms (1933/34); Volume III Arthropoda ex. Insecta (1927/1932); Volume IV Arthopoda: Insecta; Volume V Solenogastres, Mollusca, Echinoderma (1925); Volume VI Pisces / Amphibia (1930); Volume VII Reptilia / Aves (1931); Volume VIII Mammalia. The Volumes Insecta (Eds. N.P. Kristensen, R.G. Beutel) and Mammalia (Eds. M.S. Fischer, H. Schliemann) continued publication into the present with the most recent contributions in English language. Covering nearly 100 years of zoological research, the Handbook of Zoology represents a vast store of knowledge. But with the speed of scientific discovery in the past decades, a new edition of the Handbook in a new form is required. Beginning in 2010 the Handbook of Zoology will be restructured and offered additionally as a database (Zoology Online) which can be easily searched and rapidly updated. The eight thematic volumes will be replaced with smaller and more flexible groupings that reflect the current state of phylogenetic knowledge. Faster publication times through online-prepublication, reference linking, forward linking and multimedia presentations will make the Handbook of Zoology highly attractive to both authors and users. Aims and Scope The Handbook of Zoology aims to provide an in depth treatment of the entire animal kingdom from the lower invertebrates to the mammals. It publishes comprehensive overviews on animal systematics
Download or read book Prairie Conservation written by Fred B. Samson and published by Island Press. This book was released on 1996-08 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.

Download or read book Butterflies written by Carol L. Boggs and published by University of Chicago Press. This book was released on 2003-07 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Butterflies: Ecology and Evolution Taking Flight, the world's leading experts synthesize current knowledge of butterflies to show how the study of these fascinating creatures as model systems can lead to deeper understanding of ecological and evolutionary patterns and processes in general. The twenty-six chapters are organized into broad functional areas, covering the uses of butterflies in the study of behavior, ecology, genetics and evolution, systematics, and conservation biology. Especially in the context of the current biodiversity crisis, this book shows how results found with butterflies can help us understand large, rapid changes in the world we share with them—for example, geographic distributions of some butterflies have begun to shift in response to global warming, giving early evidence of climate change that scientists, politicians, and citizens alike should heed. The first international synthesis of butterfly biology in two decades, Butterflies: Ecology and Evolution Taking Flight offers students, scientists, and amateur naturalists a concise overview of the latest developments in the field. Furthermore, it articulates an exciting new perspective of the whole group of approximately 15,000 species of butterflies as a comprehensive model system for all the sciences concerned with biodiversity and its preservation.
