Book Description
Established in 1872, Yellowstone National Park is the oldest and one of the largest national parks in the world. In this remarkable book, scientists Mary Meagher and Douglas B. Houston present 100 sets of photographs that compare the Yellowstone of old with the park of today. Most of the photo sets include three pictures-not the usual two-with many of the original views dating back to the 1870s and 1880s. From the same photo points used by early photographers, Meagher and Houston rephotographed the scenes in the 1970s, and then, following the great fires of 1988, again in the 1990s. The result is an illuminating record of Yellowstone's dynamic ecosystem and its changes over time. Through close analysis of the photos and reference to the vast amount of available data, Meagher and Houston describe changes in vegetation, growth of wildlife populations, the effect of beaver occupancy on wetland areas, and geothermal and elevational shifts. At the same time they point out the extent to which many sites have not changed-despite important switches in park policy and an increase in human activity. Yellowstone National Park has long been the focus of major ecological debates. Should managers allow wildfires to burn? Should the elk and bison populations be controlled? Are too many people visiting the park? Yellowstone And The Biology Of Time offers a wealth of information to help us answer these questions. A visual treasure, this book will be of value to scientists from various disciplines as well as to the many people who care about Yellowstone and other protected wilderness areas around the world.

Book Description
Americans currently choose their president through the electoral college, an extraordinarily complex mechanism that may elect a candidate who does not receive the most votes. In this provocative book, George Edwards III argues that, contrary to what supporters of the electoral college claim, there is no real justification for a system that might violate majority rule. Drawing on systematic data, Edwards finds that the electoral college does not protect the interests of small states or racial minorities, does not provide presidents with effective coalitions for governing, and does little to protect the American polity from the alleged harms of direct election of the president. In fact, the electoral college distorts the presidential campaign so that candidates ignore most small states and some large ones and pay little attention to minorities, and it encourages third parties to run presidential candidates and discourages party competition in many states. Edwards demonstrates effectively that direct election of the president without a runoff maximizes political equality and eliminates the distortions in the political system caused by the electoral college.
