Climate and Vegetation Change, Hillslope Soil Erosion, and the Complex Nature of Late Quaternary Environmental Transitions, Eastern Mojave Desert, USA

Autor: Joseph R. McAuliffe, Leslie D. McFadden, Lyman P. Persico, Tammy M. Rittenour

Publikováno v: Quaternary, Vol 5, Iss 4, p 43 (2022)

In what are now the warm deserts of the American Southwest, direct effects of changing climate on plant distributions are typically viewed as the principal driver of vegetation changes that followed the late Pleistocene–Holocene transition (LPH). H

Role of Aeolian Dust in Shaping Landscapes and Soils of Arid and Semi-Arid South Africa

Autor: Joseph R. McAuliffe, Leslie D. McFadden, M. Timm Hoffman

Publikováno v: Geosciences, Vol 8, Iss 5, p 171 (2018)

The deposition of fine aeolian sediment profoundly influences the morphology of several different landscapes of the arid and semi-arid western portion of South Africa. Such landscapes and features include: (1) regularly-spaced mounds known as heuwelt

Late Quaternary Soil Development Enhances Aeolian Landform Stability, Moenkopi Plateau, Southern Colorado Plateau, USA

Autor: Amy L. Ellwein, Leslie D. McFadden, Joseph A. McAuliffe, Shannon A. Mahan

Publikováno v: Geosciences, Vol 8, Iss 5, p 146 (2018)

The Moenkopi dune field in northeastern Arizona covers roughly 1250 km2, but most of the field is inactive. Dune deposits on the Moenkopi Plateau (MP) have remained inactive throughout the Holocene despite periods of elevated aridity or historical re

Whether or not heuweltjies: Context-dependent ecosystem engineering by the southern harvester termite, Microhodotermes viator

Autor: Joseph R. McAuliffe, Matthew P. King, Wesley Bell, Leslie D. McFadden, Sam Jack, M. Timm Hoffman

Publikováno v: Journal of Arid Environments. 163:26-33

Regularly spaced earthen mounds called heuweltjies dot landscapes of the succulent Karoo of western South Africa. Colonies of the western harvester termite, Microhodotermes viator typically occupy the mounds, but there is substantial, unresolved deba

Landscape patterning created by the southern harvester termite, Microhodotermes viator: Spatial dispersion of colonies and alteration of soils

Autor: Veronica Nixon, Sam Jack, Matthew P. King, Leslie D. McFadden, M. Timm Hoffman, Wesley Bell, Joseph R. McAuliffe

Publikováno v: Journal of Arid Environments. 162:26-34

The southern harvester termite (Microhodotermes viator) is often associated with large, regularly spaced earthen mounds called heuweltjies in western South Africa. However, there is considerable debate regarding whether or not the termites play any r
