Kalahari vegetation: veld condition trends and ecological status of species

Koedoe: African Protected Area Conservation and Science, 1991
Grazing intensity gradients were determined in the duneveld, river terrace and river bed habitats of the Kalahari Gemsbok National Park. Under increased grazing, a species composition characterised mostly by annual forbs and grasses results. In all three

Caddo Ceramic Vessels from the T. M. Sanders Site (41LR2) on the Red River in Lamar County, Texas [PDF]

, 2016
The T. M. Sanders site (41LR2) is one of the more important ancestral Caddo sites known in East Texas, primarily because of its two earthen mounds and the well-preserved mortuary features of Caddo elite persons buried in Mound No. 1 (the East Mound). The

Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada

Journal of Quaternary Science, EarlyView.
Abstract We document the early decay of the Late‐Pleistocene Cordilleran Ice Sheet in the central portion of the Rocky and Cariboo Mountains and the Rocky Mountain Trench in east‐central British Columbia. Glacial lakes impounded at the eastern margin of the ice sheet occupied watersheds on the west flank of the central Rocky Mountains, leaving ...

Geometry, kinematics and rates of deformation in a normal fault segment boundary, central Greece [PDF]

, 2004
The geometry, kinematics and rates of deformation within a fault segment boundary between the ends of two major active normal fault segments have been investigated through examination of a faulted 126 ka marine terrace.

River Terraces along the Upper Mabechi River

Annals of The Tohoku Geographycal Asocciation, 1987
Formation of river terraces along the upper Mabechi River in northeast Japan is investigated tephrochronologically and its relation to piedmont gentle slope is discussed.Four terraces, that is, the Higher Terrace, Terrace I, Terrace II and Terrace III, are recognized in the study area.

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

Journal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Age of Ohakea Terrace, Rangitikei River [PDF]

New Zealand Journal of Geology and Geophysics, 1962
Abstract Gravel with logs of wood at Rangitawa Stream, Wellington land district, that has been radiocarbon-dated at 3,000 years before present was previously correlated with the gravel of the Ohakea Terrace. Loess is absent above the gravel with logs, but about a foot of loess overlies typical Ohakea Gravel.

Recreation Service Supply–Demand Relationship and Driving Mechanism Analysis in the Three Gorges Reservoir Area, China

Land Degradation &Development, EarlyView.
ABSTRACT Clarifying the relationship between the supply and demand of recreation service not only enhances our comprehension of how cultural ecosystem services impact human well‐being, but also offers a theoretical foundation and scientific basis for developing regional landscape management strategies.

Evaluation of Sediment Connectivity Indices to Improve the Prediction of the Spatiotemporal Variability of Sediment Yield for a Large River Basin (Wei River, China)

Land Degradation &Development, EarlyView.
ABSTRACT Sediment connectivity between source areas and the main streams or local sinks is a complex and dynamic process, especially in large basins due to multiple heterogeneities and interactions between connectivity components. Sediment connectivity indices are promising tools to investigate sediment transport, especially in data‐scarce or large ...
