Tracking Bare Sand Mobilization Arising From Landscape Manipulations In The Grasslands Destabilization Experiment (Gdex) In The Nebraska Sandhills Using Imaging Spectroscopy, Benjamin Helder
The Journal of Undergraduate Research
The Grassland Destabilization Experiment (GDEX) is a landscape scale manipulative experiment initiated in 2004 in the Nebraska Sandhills to evaluate changes in surface properties following the abrupt loss of stabilizing vegetation. The GDEX features five treatments allocated among ten plots of 120 m in diameter (1.13 ha). The Aggressive Bare Sand protocol included chemical defoliation and subsequent shallow disking and raking in 2004 to devegetate the plot with periodic physical disturbance to maintain bare sand. The Long Term Disturbance (Press) protocol includes an initial chemical defoliation in May 2005 and seasonal spring reapplications, but no physical disturbance. Short Term Disturbance …

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …

Access to earth observation data has become critically important for the wellbeing of society. A major impediment to achieving widespread sharing of earth observation data is lack of an operational web-wide system that is transparent and consistent in allowing users to legally access and use the earth observations of others without seeking permission from data contributors or investigating terms of usage on a case-by-case basis. This article explores approaches to supplying a license-based system to overcome this impediment in the context of the Global Earth Observation System of Systems. It discusses the benefits and drawbacks of the explored approaches and …

Terminal Archaic Settlement Pattern And Land Cover Change In The Rio Ilave, Southwestern Lake Titicaca Basin, Perú, Nathan M. Craig, Mark Aldenderfer, Paul Baker, Catherine Rigsby
Nathan M Craig
Researchers have argued the modern Altiplano land cover—one of bunch grasses and few indigenous tree species—is an anthropogenic artifact of land use practices initiated after the arrival of Europeans in the sixteenth century a.d. Recent paleoenvironmental studies of the Lake Titicaca Basin challenge this assertion. Archaeological survey and excavation data from the Rio Ilave drainage indicate that settlement aggregation and reduced residen¬tial mobility began in the Late Archaic Period about 3000 cal b.c. Terminal Archaic occupational intensity increased after 2000 cal b.c. and continued up until about 1300 cal b.c., which marks the beginning of the Formative in the basin. …
