Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Life-Histories of Northern Animals, Vol. 1: An Account of the Mammals of Manitoba, Grass Eaters This aims to be a book of popular Natural History on a strictly scientific basis. In it are treated some 60 quadrupeds that I have known and studied for many years. Although I have limited the scope to the 60 species that are found in Manitoba, this takes in all the large land mammals of the United States, except about a dozen, including five of the big game. Having followed these 60 into all parts of their ranges, I have virtually included the Continent from Labrador to California. A glance at the map will show that I have had unusual opportunities for gathering material, having visited nearly every State in the Union, on trips to collect specimens or information.

Book excerpt: Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.

Download or read book Hibernation and the Hypothalamus written by Nicholas Mrosovsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammalian hibernation is commonly thought of as something completely out of the ordinary, a "unique and unorthodox state." The present book takes the opposite view. It argues that the physiological achievements of hibernators do not deEend on special mechanisms but on special use of ordinary mechanisms. It is precisely this that makes the hibernators important. If the hibernators de pend on some unique physiological principle their study is that of a biological curio. But if they are using basic mammalian systems in a quantitatively extreme way, then they are a naturally occurring preparation of enormous potential. Hibernation involves every aspect of the animal's biology from fat metabo lism to behavior, from thermoregulation to dental caries; every system in the body is affected in some way or other by hibernation. A comprehensive account of hibernation would be almost coextensive with an account of the whole of mammalian biology. The present book does not attempt to describe everything that has been discovered about hibernation. Excellent coverage for that already exists in the proceedings of three recent symposia and in the other major source materials listed on page 233. There is in fact an enormous amount of information already available. But there is a difference between information and understanding. Despite the increasing volume of research and growing interest in mammalian hibernation, there is little appreciation of the essential characteristics of the phenomena. The pieces of the puzzle lie scattered.
