In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.
"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."
Applies Red List data to calculate a Red List Index.

This volume presents over fifteen years (1981-1996) of archaeometallurgy surveys and specifically the excavations of an Early Bronze Age miners' village, Goltepe and its associated tin mine, Kestel. The results of the surface surveys, test pit operations, profile trenches and excavation finds demonstrate that processing of cassiterite-rich ore was the primary function of activities at Goltepe. The variety and density of tin-rich vitrified crucibles as well as ground, powdered tin-rich ore from excavated contexts were only some of the several lines of evidence. Other finds indicated that the site was profoundly associated with metal production. Weighty evidence came in the numbers of multifac...
