دانلود کتاب In quest of Great Lakes Ice Age vertebrates

"In Quest of Great Lakes Ice Age Vertebrates details the Ice Age fishes, amphibians, reptiles, birds, and mammals in the states and province surrounding the Great Lakes. Holman's work begins with definitions of concepts and terms for the general audience and a general discussion of how the last ice age, the Pleistocene Epoch, affected our physical and biological world. Discussed are the methods and tools employed in the collection of vertebrate fossils, as well as the ethics and protocol used in the maintenance of a useful collection. These discussions are combined with details of each animal's structure, habits, habitats, and ecological importance. The heart of the book is a species-by-species account of the Pleistocene vertebrates of the region, followed by an examination of the compelling problems of the Pleistocene relative to faunal interpretations, including overall ecological makeup of the region's fauna, vertebrate range adjustment that occurred in the region, Pleistocene extinction effects on the animals of the region, the aftermath of the Ice Age, and a look at what the future may hold for the region."--Jacket.  Read more...
