Download or read book Birds of Prey of the East written by Brian K. Wheeler and published by Princeton University Press. This book was released on 2018-06-19 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds of Prey of the East and its companion volume, Birds of Prey of the West, are the most comprehensive and authoritative field guides to North American birds of prey ever published. Written and lavishly illustrated with stunning, lifelike paintings by leading field-guide illustrator, photographer, and author Brian Wheeler, the guides depict an enormous range of variations of age, sex, color, and plumage, and feature a significant amount of plumage data that has never been published before. The painted figures illustrate plumage and species comparisons in a classic field-guide layout. Each species is shown in the same posture and from the same viewpoint, which further assists comparisons. Facing-page text includes quick-reference identification points and brief natural history accounts that incorporate the latest information. The range maps are exceptionally accurate and much larger than those in other guides. They plot the most up-to-date distribution information for each species and include the location of cities for more accurate reference. Finally, the guides feature color habitat photographs next to the maps. The result sets a new standard for guides to North America's birds of prey.

Download or read book Permafrost in Canada written by Roger J.E. Brown and published by University of Toronto Press. This book was released on 1970-12-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permafrost is the thermal condition of the earth’s crust when its temperature has been below 32°F continuously for a number of years. Half of Canada’s land surface lies in the permafrost region—either in the continuous zone where the ground is frozen to a depth of hundreds of feet, or in the discontinuous zone where permafrost is thinner, and there are areas of unfrozen ground. The existence of permafrost causes problems for the development of the northern regions of all countries extending into the Arctic. Mining operations are hindered by frozen ore which resists blasting and is difficult to thaw. Agriculture is restricted by the presence of permafrost near the ground surface which limits the soil available for plant growth. Engineering structures are also affected by the low temperatures. Ice layers give soil a rock-like structure with high strength. However heat transmitted by buildings often causes the ice to melt, and the resulting slurry is unable to support the structure. Many settlements in northern Canada have examples of structural damage or failure caused by permafrost. In the construction and maintenance of railways, buildings, water and sewage lines, dams, roads, bridges, and airfields, normal techniques must often be modified at additional cost because of permafrost. For the last twenty-five years scientific investigations and engineering projects have increased steadily in Canada’s permafrost region, and it is now technically possible to build any structure or conduct any activity on the worst soils and under permafrost conditions. This comprehensive analysis of permafrost—its origin, definition, and occurrence, and the effect it has on industry and agriculture—will be invaluable to the growing number of people working in the north and to those interested in its development.
