We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African ...countries. Mean AGB is 395.7 Mg dry mass ha⁻¹ (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region attaining AGB values (429 Mg ha⁻¹) similar to those of Bornean forests, and significantly greater than East or West African forests. AGB therefore appears generally higher in palaeo-compared with neotropical forests. However, mean stem density is low (426 ± 11 stems ha⁻¹ greater than or equal to 100 mm diameter) compared with both Amazonian and Bornean forests (cf. approx. 600) and is the signature structural feature of African tropical forests. While spatial autocorrelation complicates analyses, AGB shows a positive relationship with rainfall in the driest nine months of the year, and an opposite association with the wettest three months of the year; a negative relationship with temperature; positive relationship with clay-rich soils; and negative relationships with C : N ratio (suggesting a positive soil phosphorus-AGB relationship), and soil fertility computed as the sum of base cations. The results indicate that AGB is mediated by both climate and soils, and suggest that the AGB of African closed-canopy tropical forests may be particularly sensitive to future precipitation and temperature changes.
Organized by the theme of place and place-making in the Southwest, Contemporary Archaeologies of the Southwest emphasizes the method and theory for the study of radical changes in religion, ...settlement patterns, and material culture associated with population migration, colonialism, and climate change during the last 1,000 years. Chapters address place-making in Chaco Canyon, recent trends in landscape archaeology, the formation of identities, landscape boundaries, and the movement associated with these aspects of place-making. They address how interaction of peoples with objects brings landscapes to life. Representing a diverse cross section of Southwestern archaeologists, the authors of this volume push the boundaries of archaeological method and theory, building a strong foundation for future Southwest studies. This book will be of interest to professional and academic archaeologists, as well as students working in the American Southwest.

Examines how the proposed Yucca Mountain nuclear waste repository system will impact ...tourism in southern Nevada and other visitor-oriented rural counties bisected by planned waste transportation corridors.

Anthropological archaeologists have long attempted to develop models that will let them better understand the evolution of human social organization. In our search to understand how chiefdoms and ...states evolve, and how those societies differ from egalitarian 'bands', we have neglected to develop models that will aid the understanding of the wide range of variability that exists between them. This volume attempts to fill this gap by exploring social organization in tribal - or 'autonomous village' - societies from several different ethnographic, ethnohistoric, and archaeological contexts - from the Pre-Pottery Neolithic Period in the Near East to the contemporary Jivaro of Amazonia.
Hinterlands and Regional Dynamics in the Ancient Southwest is the first volume dedicated to understanding the nature of and changes in regional social autonomy, political hegemony, and organizational ...complexity across the entire prehistoric American Southwest. With geographic coverage extending from the Great Plains to the Colorado River, and from Mesa Verde to the international border, the volume's ten case studies synthesize research that enhances our understanding of the ancient Southwest's highly variable demographic, land use, and economic histories. For this volume, "hinterlands" are those areas whose archaeological records do not disclose the ceramic, architectural, and network evidence that initially led to the establishment of the Hohokam, Chaco, and Casas Grandes regional systems. Employing a variety of perspectives, such as the cultural landscapes approach, heterarchy, and the common-pool resource model, as well as technical methods, such as petrographic and stylistic-attribute analyses, the volume's contributors explore variation in hinterland identities, subsistence ecology, and sociopolitical organization as regional systems expanded and contracted between the 9th and 14th centuries AD. The hinterlands of the prehistoric Southwest were home to a substantial number of people and were often used as resource catchments by the inhabitants of regional systems. Importantly, hinterlands also influenced developments of nearby regional systems, under whose footprint they managed to retain considerable autonomy. By considering the dynamics between hinterlands and regional systems, the volume reveals unappreciated aspects of the ancient Southwest's peoples and their lives, thereby deepening our awareness of the region's rich and complicated cultural past.
Southwestern archaeologists have long recognized that platform mounds required a considerable amount of labor and organizational skill to build. Attempts to specify these behavioral dimensions have ...generally met with failure, however, either due to a lack of data or because researchers have been unable to place mound construction within a larger social context. Recent excavations at the Meddler Point site in central Arizona provide important new data for addressing these issues. In this article, the material and labor costs involved in building the Meddler Point platform mound are considered. The implications of these figures for understanding Classic period social organization at the site are then examined.
Recent archaeological research in the Southwest has led to a reassessment of migration in explaining social change. Ethnohistoric data from Southwestern Pueblos may provide better analogues for ...prehistoric migrations in the region than models derived from contemporary urban contexts. Documentary evidence and climatic data from the early Historic period inform on demographic, environmental, economic, and social "pushes" that motivate groups to move, and the "pulls" that influence where they resettle. Scale, structure, and distance of the movement itself are examined, as these factors affect the mechanisms by which immigrants are integrated into local settlements.
