The Galápagos Islands are one of the world’s premiere nature attractions, home to unique ecosystems widely thought to be untouched and pristine. Historical Ecology and Archaeology in the Galápagos Islands reveals that the archipelago is not as isolated as many imagine, examining how centuries of human occupation have transformed its landscape. This book shows that the island chain has been a part of global networks since its discovery in 1535 and traces the changes caused by human colonization. Central to this history is the sugar plantation Hacienda El Progreso on San Cristóbal Island. Here, zooarchaeological and archaeobotanical evidence documents the introduction of exotic species and landscape transformations, and material evidence attests that inhabitants maintained connections to the outside world for consumer goods. Beyond illuminating the human history of the islands, the authors also look at the impact of visitors to Galápagos National Park today, raising questions about tourism’s role in biological conservation, preservation, and restoration.

Challuabamba (chī-wa-bamba)—now a developing suburb of Cuenca, the principal city in the southern highlands of Ecuador—has been known for a century as an ancient site that produced exceptionally fine pottery in great quantities. Suspecting that Challuabamban ceramics might provide a link between earlier, preceramic culture and later, highly developed Formative period art, Terence Grieder led an archaeological investigation of the site between 1995 and 2001. In this book, he and the team of art historians and archaeologists who excavated at Challuabamba present their findings, which establish the community's importance as a center in a network of trade and artistic influence that extended to the Amazon River basin and the Pacific Coast. Art and Archaeology of Challuabamba, Ecuador presents an extensive analysis of ceramics dating to 2100-1100 BC, along with descriptions of stamps and seals, stone and shell artifacts, burials and their offerings, human remains, and zooarchaeology. Grieder and his coauthors demonstrate that the pottery of Challuabamba fills a gap between early and late Formative styles and also has a definite connection with later highland styles in Peru. They draw on all the material remains to reconstruct the first clear picture of Challuabamba's prehistory, including agriculture and health, interregional contacts and exchange, red-banded incised ware and ceramic production, and shamanism and cosmology. Because southern Ecuador has received relatively little archaeological study, Art and Archaeology of Challuabamba, Ecuador offers important baseline data for what promises to be a key sector of the prehistoric Andean region.
The Fourth Edition of Greene's Protective Groups in Organic Synthesis continues to be an indispensable reference for controlling the reactivity of the most common functional groups during a synthetic sequence. This new edition incorporates the significant developments in the field since publication of the third edition in 1998, including... New protective groups such as the fluorous family and the uniquely removable 2-methoxybenzenesulfonyl group for the protection of amines New techniques for the formation and cleavage of existing protective groups, with examples to illustrate each new technique Expanded coverage of the unexpected side reactions that occur with protective groups New chart covering the selective deprotection of silyl ethers 3,100 new references from the professional literature The content is organized around the functional group to be protected, and ranges from the simplest to the most complex and highly specialized protective groups.
Binary systems of stars are as common as single stars. Stars evolve primarily by nuclear reactions in their interiors, but a star with a binary companion can also have its evolution influenced by the companion. Multiple star systems can exist stably for millions of years, but can ultimately become unstable as one star grows in radius until it engulfs another. This volume, first published in 2006, discusses the statistics of binary stars; the evolution of single stars; and several of the most important kinds of interaction between two (and even three or more) stars. Some of the interactions discussed are Roche-lobe overflow, tidal friction, gravitational radiation, magnetic activity driven by rapid rotation, stellar winds, magnetic braking and the influence of a distant third body on a close binary orbit. A series of mathematical appendices gives a concise but full account of the mathematics of these processes.
This is the second volume of textbooks on atomic, molecular and optical physics, aiming at a comprehensive presentation of this highly productive branch of modern physics as an indispensable basis for many areas in physics and chemistry as well as in state of the art bio- and material-sciences. It primarily addresses advanced students (including PhD students), but in a number of selected subject areas the reader is lead up to the frontiers of present research. Thus even the active scientist is addressed. This volume 2 introduces lasers and quantum optics, while the main focus is on the structure of molecules and their spectroscopy, as well as on collision physics as the continuum counterpart to bound molecular states. The emphasis is always on the experiment and its interpretation, while the necessary theory is introduced from this perspective in a compact and occasionally somewhat heuristic manner, easy to follow even for beginners.
