Geoarchaeology in semi-arid landscapes
… the potential of open-air sites in the semi-arid interior. Research at open-air sites poses analytical difficulties, such as poor preservation of organic materials, which has led to an oversight of the archaeological potential of open-air sites. This creates a knowledge gap regarding human …

Protected areas and management agencies in arid landscapes.
… with the management of public protected areas in arid landscapes are analyzed for their ability to successfully execute their missions. First, the characteristics of arid landscapes are explored. Abiotic, biotic, and cultural--including perceptual--aspects of arid landscapes are considered and …

Advancing UAV-Based Remote Sensing and Machine Learning for Ecological Monitoring, Habitat Disturbance Detection, and Forensic Science in Arid Landscapes
… and camera systems at study sites within the arid deserts of the western United States to demonstrate low-cost, user-defined, scientific, and civil applications. In chapter one we use a UAV-based multispectral camera to classify vegetation with a goal of detecting individual plants of the …

SOIL MOISTURE VARIABILITY: IMPLICATIONS FOR THE HYDROLOGY, EROSION AND MANAGEMENT OF GULLIED CATCHMENTS IN CENTRAL SPAIN
In semi-arid environments, the combination of a non-uniform distribution of vegetation, an often highly irregular terrain and complex geological, pedological and management histories have frequently given rise to considerable spatial variability in the physical and hydrological properties of soils. …

Development of resource-rich patches by soil-disturbing animals in arid environments
In arid landscapes limited resources are concentrated into fertile patches that allow greater productivity than would otherwise be expected. Fertile patches are created and maintained by processes that modify soil topography and interrupt the flow of resources across the landscape. These processes …

Characterising the Namaqualand Mudbelt: Chronology, Palynology and Palaeoenvironments
… H7, from the Namaqualand Mudbelt representing an arid and highly variable landscape. As bulk organic radiocarbon ages previously proved problematic, with anomalous reversals, the primary objective was to improve chronology and palaeoenvironmental reconstructions through high resolution 813C, 81SN …

A multi-scale study on the movement ecology of Afrotropical waterbirds
… informed conservation plans. Waterbirds in semiarid southern Africa are an ideal study group for understanding interactions between movement and environmental factors because they exhibit a wide range of movement strategies and are located within a landscape in which resources are characterised …

Soil Heterogeneity in Arid Shrublands: Biotic and Abiotic Processes
… the evolution of soil heterogeneity on arid alluvial fans. Soil formation begins when depositional or erosional processes cease and a geomorphic surface becomes stable. The transformation of sediment to soil (pedogenesis) affects a multitude of hydrologic processes operating across a …
