When Egypt became a province of the Roman Empire in 30 B.C. after the deaths of Antony and Cleopatra, its vast and mysterious frontier lands had an important impact on the commerce, politics, and culture of the empire. This engrossing book -- part history and part gazetteer -- focuses on Rome's Egyptian frontier, describing the ancient fortresses, temples, settlements, quarries, and aqueducts scattered throughout the region and conveying a vivid sense of what life was like for its inhabitants.

Robert B. Jackson has journeyed, by jeep and on foot, to virtually every known Roman site in the area, from Siwa Oasis, forty-five kilometers from the modern Libyan border, to the Sudan. Drawing on both archaeological and historical information, he discusses these sites, explaining how Rome extracted exotic stone and precious metals from the mountains of the Eastern Desert, channeled the wealth of India and East Africa through the desert via ports on the Red Sea, constructed and manned fortresses in the distant oases of the Western Desert, and facilitated the expansion of agricultural communities in the desert that eventually experienced the earliest large-scale conversions to Christianity in Egypt. Elegantly written and illustrated with many handsome photographs, the book will be a treasured resource for archaeologists, classicists, and travelers to the region.

Ecology at the ecosystem level has both necessitated and benefited from new methods and technologies as well as those adapted from other disciplines. With the ascendancy of ecosystem science and management, the need has arisen for a comprehensive treatment of techniques used in this rapidly-growing field. Methods in Ecosystem Science answers that need by synthesizing the advantages, disadvantages and tradeoffs associated with the most commonly used techniques in both aquatic and terrestrial research.The book is divided into sections addressing carbon and energy dynamics, nutrient and water dynamics, manipulative ecosystem experiements and tools to synthesize our understanding of ecosystems. Detailed information about various methods will help researchers choose the most appropriate methods for their particular studies. Prominent scientists discuss how tools from a variety of disciplines can be used in ecosystem science at different scales.

Human-driven greenhouse emissions are increasing the velocity of climate change and the frequency and intensity of climate extremes far above historical levels. These changes, along with other human-perturbations, are setting the conditions for more rapid and abrupt ecosystem dynamics and collapse. This book presents new evidence on the rapid emergence of ecosystem collapse in response to the progression of anthropogenic climate change dynamics that are expected to intensify as the climate continues to warm. Discussing implications for biodiversity conservation, the chapters provide examples of such dynamics globally covering polar and boreal ecosystems, temperate and semi-arid ecosystems, as well as tropical and temperate coastal ecosystems. Given its scope, the volume appeals to scientists in the fields of general ecology, terrestrial and coastal ecology, climate change impacts, and biodiversity conservation.

In April of 1910, two courageous boys, ages six and ten, left Frederick, Oklahoma, on a 2,500 mile horseback ride to New York. Temple and Louie (Bud) Abernathy were adventurous youngsters who rodeo to New York City with the goal being to see their father and Theodore Roosevelt. Their trip attracted national attention and they were welcomed to New York City as heroes. They even rode in a ticker tape parade, riding on horseback directly behind Roosevelt's automobile.
