In the fourteenth century, a culture arose in and around the Edwards Plateau of Central Texas that represents the last prehistoric peoples before the cultural upheaval introduced by European explorers. This culture has been labeled the Toyah phase, characterized by a distinctive tool kit and a bone-tempered pottery tradition. ?Spanish documents, some translated decades ago, offer glimpses of these mobile people. Archaeological excavations, some quite recent, offer other views of this culture, whose homeland covered much of Central and South Texas. For the first time in a single volume, this book brings together a number of perspectives and interpretations of these hunter-gatherers and how they interacted with each other, the pueblos in southeastern New Mexico, the mobile groups in northern Mexico, and newcomers from the northern plains such as the Apache and Comanche.? Assembling eight studies and interpretive essays to look at social boundaries from the perspective of migration, hunter-farmer interactions, subsistence, and other issues significant to anthropologists and archaeologists, The Toyah Phase of Central Texas: Late Prehistoric Economic and Social Processes demonstrates that these prehistoric societies were never isolated from the world around them. Rather, these societies were keenly aware of changes happening on the plains to their north, among the Caddoan groups east of them, in the Puebloan groups in what is now New Mexico, and among their neighbors to the south in Mexico.

Soil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.

This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.
