Pielou describes the natural history of fresh water--a vital ingredient of the natural world--exploring its sources and destinations, how it moves over and under the earth, and how it ends up in the atmosphere. 81 line drawings.
The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.
This book is a practical, portable guide to all of the Arctic's natural history—sky, atmosphere, terrain, ice, the sea, plants, birds, mammals, fish, and insects—for those who will experience the Arctic firsthand and for armchair travelers who would just as soon read about its splendors and surprises. It is packed with answers to naturalists' questions and with questions—some of them answered—that naturalists may not even have thought of.
A detailed introduction to the methods used by ecologists--classification and ordination--to clarify and interpret large, unwieldy masses of multivariate field data. Permits ecologists to understand, not just mechanically use, pre-packaged programs for multivariate analysis. Demonstrates these techniques using artificial data simple enough for every analytical step to be understood.
Perfect for reminders, calendar notes, homework notes, name tags, and much more! Each pad features 50 acid-free, lignin-free sheets and measures approx. 6" x 7.5". Available in a variety of prints, notepads are an essential addition to any teacher's desk!
Examines the evolution of life on a constantly changing planet and the results of that process. Explores new insights from plate tectonics; from deep ocean life investigations; from island biogeography; from growing knowledge about past geography, climates and ecology; and from development in evolutionary theory will interest `outdoor' biologists of all kinds, ecologists, students of evolution, oceanographers, paleontologists, and geographers. With numerous maps and diagrams and a bibliography of over 300 references.
A full description of computer-based methods of analysis used to define and solve ecological problems. Multivariate techniques permit summary of complex sets of data and allow investigation of many problems which cannot be tackled experimentally because of practical restraints.

This book is a comprehensive guide to the natural history of the North Slope, the only arctic tundra in the United States. The first section provides detailed information on climate, geology, landforms, and ecology. The second provides a guide to the identification and natural history of the common animals and plants and a primer on the human prehistory of the region from the Pleistocene through the mid-twentieth century. The appendix provides the framework for a tour of the natural history features along the Dalton Highway, a road connecting the crest of the Brooks Range with Prudhoe Bay and the Arctic Ocean, and includes mile markers where travelers may safely pull off to view geologic formations, plants, birds, mammals, and fish. Featuring hundreds of illustrations that support the clear, authoritative text, Land of Extremes reveals the arctic tundra as an ecosystem teeming with life.
