Download or read book Butterflies of New Jersey written by Michael Gochfeld and published by Rutgers University Press. This book was released on 1997 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Butterfly watching has begun to gain the popularity that bird watching has enjoyed for half a century. Much as birds served as a flagship of the conservation movement in this country, butterflies are coming to be seen as the rallying point for the protection of invertebrate species--now regarded as increasingly important for the well-being of all members of the ecosystem. Butterflies of New Jersey discusses the behavior, status, distribution, taxonomy, ecology, and conservation of butterflies in New Jersey. It is an innovative companion and complement to any butterfly identification guide of the Northeast. It pays particular attention to the place of butterflies in the ecosystem of New Jersey and neighboring regions and their relationships to other butterflies around the world. Its detailed species accounts of 140-plus kinds of butterflies found in the state and neighboring regions (out of 700 North American species) alert butterfly watchers to changes in populations over time. Where other butterfly guides typically include a section on collecting butterflies, this one includes a detailed chapter on protecting them by creating butterfly gardens and preventing habitat destruction. Butterflies of New Jersey is indispensable for everyone interested in the butterflies and natural history of the Garden State and its neighbor.

Available in PDF, EPUB and Kindle. Book excerpt: Monarch butterflies abound in Canada. We marvel at their beauty and the magic of their metamorphosis. Familiar as they are to us, these tiny creatures nevertheless harbour many secrets. Perhaps the deepest mystery is the monarchs' annual migration. Each autumn, they travel unimaginably long distances, something no other butterflies do. How do they know when to migrate? How, unguided by memory, do they navigate to their destination in the heart of the threatened Mexican jungle? Sue Halpern recounts the mesmerizing story of these mysteries, and the race to solve them. She describes the discoveries of Canadian biologist Fred Urquhart and his wife, who first encouraged amateur lepidopterists to tag butterflies. We follow her to Mexico, where she searches for butterflies. She introduces us to Don Davis, an enthusiast who has tagged an estimated 20,000 monarchs since 1985. And though terrified of flying, she takes us on a flight with University of Toronto biologist David Gibo, as they attempt to predict the flight vectors of butterflies. Astonishing, fascinating, Four Wings and a Prayer, like our encounters with these delicate winged creatures, is a rare gem.

Download or read book Ecological Indicators for the Nation written by National Research Council and published by National Academies Press. This book was released on 2000-04-12 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental indicators, such as global temperatures and pollutant concentrations, attract scientists' attention and often make the headlines. Equally important to policymaking are indicators of the ecological processes and conditions that yield food, fiber, building materials and ecological "services" such as water purification and recreation. This book identifies ecological indicators that can support U.S. policymaking and also be adapted to decisions at the regional and local levels. The committee describes indicators of land cover and productivity, species diversity, and other key ecological processesâ€"explaining why each indicator is useful, what models support the indicator, what the measured values will mean, how the relevant data are gathered, how data collection might be improved, and what effects emerging technologies are likely to have on the measurements. The committee reviews how it arrived at its recommendations and explores how the indicators can contribute to policymaking. Also included are interesting details on paleoecology, satellite imagery, species diversity, and other aspects of ecological assessment. Federal, state, and local decision-makers, as well as environmental scientists and practitioners, will be especially interested in this new book.
