Book Description
Excerpt from Shenandoah National Park Long-Term Ecological Monitoring System: Section III., Aquatic Component User Manual Geological formations were selected as the sec ond level of classification because the snp has a uniquely diverse geology and resulting water chemis try, particularly alkalinity. There are great differences among watersheds, and often between adjacent watersheds. Alkalinity and related water chemistry are probably significant factors affecting the distribu tion of the aquatic biota. Information on geological formations and alkalinity can be obtained from Gathright (1976) and Dise respectively. Streams in the snp seldom have their watersheds entirely within a single geological formation. An effort should be made to establish stream sites in watersheds which have at least 75% of their area within one of the geological formation categories. Elevation affects the distribution of aquatic biota indirectly because of factors such as stream width, depth, current velocity, valley shading and tempera ture. The snp is located entirely within the northern section of the Blue Ridge physiographic province, which is the narrow (about 8 km) mountainous area between the low-lying Piedmont province to the east and the Ridge and Valley province to the west (hoffman 1969, Gathright Because of the narrow moun tainous, characteristics of the Blue Ridge, drainage basins in this province typically have a steep gradient. Drainage basins on the west slope follow -a trellis pattern, in which the small streams flowing down the mountains are parallel and join the main stream in the valley (shenandoah River) at right angles (reid and Wood Those on the east slope follow a den dritic pattern, so-called because of the resemblance to tree roots (reid and Wood The criterion of m (1800 ft) for distinguishing upper and lower sites was selected because field observations indi cated that streams in the snp tended to become very narrow and shallow (several m wide and less than knee deep) approximately above that elevation. This delimitation is somewhat arbitrary and can be varied within reason when it is desirable to have both an upper and lower site on the same stream. Elevation is best determined from the Potomac Appalachian Trail Club maps (scale The usgs min topographic maps are not as useful because they are not as accurate regarding trails, fire roads, and stream permanency.

Book Description
During the 1906 San Francisco earthquake, the Point Reyes Peninsula, forty miles farther north along the San Andreas Fault, shook loose from its temporary moorings to the California coastline and lurched to the northwest by some twenty feet. The powerful quake that terrorized the city also tore through the land and jarred the rural inhabitants of Point Reyes. It was another abrupt step in the peninsula's slow creep from southern to northern California, yielding a piece of land quite divergent from the California mainland to which it is now affixed. Although pressure along the San Andreas Fault continued to build for the remainder of the century, there were no other geologic events of a magnitude that could so drastically alter the land's surface. By contrast, human events since 1906 have significantly altered the peninsula's landscape. In the century following the earthquake, economic, cultural, and political forces gradually reshaped Point Reyes. Possibly the biggest tremor took place in 1962, when Congress created, and President John F. Kennedy signed into law, the Point Reyes National Seashore. At that juncture, the political geography of the land, as a new unit of the National Park Service (NPS), was about to change dramatically. This volume, Managing a Land in Motion: An Administrative History of Point Reyes National Seashore, traces, explains, and analyzes the ideas and events that produced the national seashore and transpired in the forty years that followed.

Book Description
In the face of so many unprecedented changes in our environment, the pressure is on scientists to lead the way toward a more sustainable future. Written by a team of ecologists, Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide provides a framework that natural resource managers and researchers can use to design monitoring programs that will benefit future generations by distilling the information needed to make informed decisions. In addition, this text is valuable for undergraduate- and graduate-level courses that are focused on monitoring animal populations. With the aid of more than 90 illustrations and a four-page color insert, this book offers practical guidance for the entire monitoring process, from incorporating stakeholder input and data collection, to data management, analysis, and reporting. It establishes the basis for why, what, how, where, and when monitoring should be conducted; describes how to analyze and interpret the data; explains how to budget for monitoring efforts; and discusses how to assemble reports of use in decision-making. The book takes a multi-scaled and multi-taxa approach, focusing on monitoring vertebrate populations and upland habitats, but the recommendations and suggestions presented are applicable to a variety of monitoring programs. Lastly, the book explores the future of monitoring techniques, enabling researchers to better plan for the future of wildlife populations and their habitats. Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide furthers the goal of achieving a world in which biodiversity is allowed to evolve and flourish in the face of such uncertainties as climate change, invasive species proliferation, land use expansion, and population growth.

Book Description
Use of and trade in wildlife is a fact of life for human society around the globe. Article IV of the CITES Convention requires that exporting countries restrict trade in Appendix II species to levels that are not detrimental either to species? survival, or to their role within the ecosystems in which they occur (known as the ?non-detriment finding?). Based on two workshops convened by IUCN to develop some pragmatic assistance for Scientific Authorities, this publication presents the background to the development of the non-detriment finding checklist and explains how the checklist itself is designed to work, in the hope that Scientific Authority staff will take and develop the parts of the approach that they find useful.

Book Description
Exploring Earth Science by Reynolds/Johnson is an innovative textbook intended for an introductory college geology course, such as Earth Science. This ground-breaking, visually spectacular book was designed from cognitive and educational research on how students think, learn, and study. Nearly all information in the book is built around 2,600 photographs and stunning illustrations, rather than being in long blocks of text that are not articulated with figures. These annotated illustrations help students visualize geologic processes and concepts, and are suited to the way most instructors already teach. To alleviate cognitive load and help students focus on one important geologic process or concept at a time, the book consists entirely of two-page spreads organized into 20 chapters. Each two-page spread is a self-contained block of information about a specific topic, emphasizing geologic concepts, processes, features, and approaches. These spreads help students learn and organize geologic knowledge in a new and exciting way. Inquiry is embedded throughout the book, modeling how scientists investigate problems. The title of each two-page spread and topic heading is a question intended to get readers to think about the topic and become interested and motivated to explore the two-page spread for answers. Each chapter is a learning cycle, which begins with a visually engaging two-page spread about a compelling geologic issue. Each chapter ends with an Investigation that challenges students with a problem associated with a virtual place. The world-class media, spectacular presentations, and assessments are all tightly articulated with the textbook. This book is designed to encourage students to observe, interpret, think critically, and engage in authentic inquiry, and is highly acclaimed by reviewers, instructors, and students.
