Book Synopsis Yellowstone Wildlife by : Paul A. Johnsgard
Download or read book Yellowstone Wildlife written by Paul A. Johnsgard and published by University Press of Colorado. This book was released on 2013-06-15 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone Wildlife is a natural history of the wildlife species that call Yellowstone National Park and the Greater Yellowstone Ecosystem their home. Illustrated with stunning images by renowned wildlife photographer Thomas Mangelsen, Yellowstone Wildlife describes the lives of species in the park, exploring their habitats from the Grand Tetons to Jackson Hole. From charismatic megafauna like elk, bison, wolves, bighorn sheep, and grizzly bears, to smaller mammals like bats, pikas, beavers, and otters, to some of the 279 species of birds, Johnsgard describes the behavior of animals throughout the seasons, with sections on what summer and autumn mean to the wildlife of the park, especially with the intrusion of millions of tourists each year. Enhanced by Mangelsen’s wildlife photography, Yellowstone Wildlife reveals the beauty and complexity of these species’ intertwined lives and that of Yellowstone’s greater ecosystem.
Book Synopsis Chasing Monarchs by : Robert Michael Pyle
Download or read book Chasing Monarchs written by Robert Michael Pyle and published by Yale University Press. This book was released on 2014-04-29 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although no one had ever followed North American monarch butterflies on their annual southward journey to Mexico and California, in the 1990s there were well-accepted assumptions about the nature and form of the migration. But to Robert Michael Pyle, a naturalist with long experience in monarch conservation, the received wisdom about the butterflies’ long journey just didn’t make sense. In the autumn of 1996 he set out to uncover the facts, to pursue the tide of “cinnamon sailors” on their long, mysterious flight. Chasing Monarchs chronicles Pyle’s 9,000-mile journey to discover firsthand the secrets of the monarchs’ annual migration. Part road trip, part outdoor adventure, and part natural history study, Pyle’s book overturns old theories and provides insights both large and small regarding monarch butterflies, their biology, and their spectacular migratory travels. Since the book’s first publication, its controversial conclusions have been fully confirmed, and monarchs are better understood than ever before. The Afterword for this volume includes not only updated information on the myriad threats to monarch butterflies, but also various efforts under way to ensure the future of the world’s most amazing butterfly migration.

Book Synopsis Biology of Blood-Sucking Insects by : Mike Lehane
Download or read book Biology of Blood-Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
Book Synopsis Freshwater key biodiversity areas in the Mediterranean basin hotspot by : V. Barrios
Download or read book Freshwater key biodiversity areas in the Mediterranean basin hotspot written by V. Barrios and published by IUCN. This book was released on 2014-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the Mediterranean basin biodiversity hotspot is well known for its globally important biodiversity, its freshwater biodiversity has not been as widely recognized for its importance. Through this project, freshwater key biodiversity areas (KBAs) have now been identified, mapped and validated throughout much of the Mediterranean hotspot. It is now important to raise awareness of their status as validated freshwater KBAs and to develop plans for appropriate conservation actions at these sites, as this biodiversity is highly threatened largely due to the conflicting demands upon a diminishing supply of fresh water which is further exacerbated by the increased severity of drought across the region.
