Climatic/edaphic controls on soil carbon/nitrogen response to shrub encroachment in desert grassland.
The proliferation of woody plants in grasslands over the past 100+ years can alter carbon, nitrogen, and water cycles and influence land surface-atmosphere interactions. Although the majority of organic carbon in these ecosystems resides belowground, there is no consensus on how this change in land cover has affected soil organic carbon (SOC) and total nitrogen (TN) pools. The degree to which d...
متن کاملModeling the reflectance anisotropy of Chihuahuan Desert grass-shrub transition canopy-soil complexes
The goal of the research presented here is to understand better the factors controlling the remotely sensed signal returned in the solar wavelengths from Chihuahuan Desert grass-shrub transition canopy-soil complexes. The specific objectives were twofold: to evaluate the importance of the different elements (overstory, understory, soil) in the bi-directional reflectance distribution function (B...
متن کاملInfluence of Late Quaternary Climatic Changes on Geomorphic and Pedogenic Processes on a Desert Piedmont, Eastern Mojave Desert, California
Radiocarbon dating of late Quaternary deposits and shorelines of Lake Mojave and cation-ratio numerical age dating of stone pavements (Dorn. 1984) on the adjacent Soda Mountains piedmont provide age constraints for alluvial and eolian deposits. These deposits are associated with climatically controlled stands of Lake Mojave during the past 15.000 yr. Six alluvial fan units and three eolian stra...
متن کاملRemote sensing of woody shrub cover in desert grasslands using MISR with a geometric-optical canopy reflectance model
A new method is described for the retrieval of fractional cover of large woody plants (shrubs) at the landscape scale using moderate resolution multi-angle remote sensing data from the Multiangle Imaging SpectroRadiometer (MISR) and a hybrid geometric-optical (GO) canopy reflectance model. Remote sensing from space is the only feasible method for regularly mapping woody shrub cover over large a...
متن کاملSeed Mucilage Improves Seedling Emergence of a Sand Desert Shrub
The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed m...
