Far to the south of Arizona’s sprawling metropolises, a rolling savanna of grass, oak, and mesquite rises above the surrounding deserts. The Sonoita Plain is a basin of a thousand square miles bracketed by mountains, a land once the domain of cowboys that is now more and more the focus of exurban development. These southwestern grasslands are both typical of and distinct from those of the Great Plains—similarly shaped by drought, grazing, and fire, but with a different flora and fauna, and the product of a different human history. The Appleton-Whittell Research Ranch is a tract of 8,000 acres on the Sonoita Plain that was established in 1968 by the Appleton family and that is now part of the sanctuary system of the National Audubon Society. To all appearances, it is an ordinary piece of land, but for the last 35 years it has been treated in an extraordinary way—by leaving it alone. No grazing to influence grass production. No dam building to hold back flash floods. No pest control. No fire-fighting. By employing such non-action, might we gain a glimpse of what this land was like hundreds, even thousands, of years ago? Through essays and photographs focusing on the Sanctuary and surrounding area, this book reveals the complex ecology and unique aesthetics of its grasslands and savannas. Carl and Jane Bock and Stephen Strom share a passion for the remarkable beauty found here, and in their book they describe its environment, biodiversity, and human history. People have dominated the world’s grasslands and savannas for so long that today we have no clear idea what these lands might be like without us. By understanding the lessons of the Sonoita Plain, we might gain such insight—and, more important, discover approaches to protecting the very things that attract us to such lands in the first place.
In 1540 Francisco Vasquez de Coronado introduced the first domestic livestock to the American Southwest. Over the subsequent four centuries, cattle, horses, and sheep have created a massive ecological experiment on these arid grasslands, changing them in ways we can never know with certainty. The Appleton-Whittell Research Ranch in the high desert of southeastern Arizona is an 8,000-acre sanctuary where grazing has been banned since 1968. In this spirited account of thirty years of research at the ranch, Carl and Jane Bock summarize the results of their fieldwork, which was aimed at understanding the dynamics of grasslands in the absence of livestock. The View from Bald Hill provides an intimate look at the natural history of this unique site and illuminates many issues pertaining to the protection and restoration of our nation's grasslands.
Forensic botany is the application of plant science to the resolution of legal questions. A plant's anatomy and its ecological requirements are in some cases species specific and require taxonomic verification; correct interpretation of botanical evidence can give vital information about a crime scene or a suspect or victim. The use of botanical evidence in legal investigations in North America is relatively recent. The first botanical testimony to be heard in a North American court concerned the kidnapping and murder of Charles Lindbergh's baby boy and the conviction of Bruno Hauptmann in 1935. Today, forensic botany encompasses numerous subdisciplines of plant science, such as plant anatomy, taxonomy, ecology, palynology, and diatomology, and interfaces with other disciplines, e.g., molecular biology, limnology and oceanography.Forensic Plant Science presents chapters on plant science evidence, plant anatomy, plant taxonomic evidence, plant ecology, case studies for all of the above, as well as the educational pathways for the future of forensic plant science. - Provides techniques, collection methods, and analysis of digested plant materials - Shows how to identify plants of use for crime scene and associated evidence in criminal cases - The book's companion website: http://booksite.elsevier.com/9780128014752, will host a microscopic atlas of common food plants
This book presents a broad view of contemporary research in evolutionary plant ecology. It illustrates the broad spectrum of life history stages which affect plant reproductive success in some fashion.
