The present study sought to define a possible role of phosphorus-stimulated
ammoniagenesis, previously observed in vitro and in
experimental animals, in the hypocalciuric effect of phosphorus in young
men. It was hypothesized that titrating some of the hydrogen ions
destined for excretion with ammonia would be beneficial to kidney
calcium...
Object Watershed Link Simulation (OWLS) is a physically based watershed model. In the OWLS
model, a watershed is defined as a three-dimensional object with linkages between cells and their
attributes (e.g., area, slope, soil type, etc.). A cell is defined as the linkages of edges and their attributes
(e.g., length,...
Forest spatial pattern is a primary interest of landscape ecology due to the relationships between spatial configuration of biotic components and ecological processes. The spatial pattern must be measured in meaningful ways so that relationships between forests and their environment can be analyzed. Aerial and satellite imageries provide ecologists a...
Post-settlement juniper expansion in the western states has been reported for decades,
including western juniper (Juniperus occidentalis Hook ssp. occidentalis) woodlands in the northwestern states. A 15 km2 study area in the Sheep Rock Unit of John Day Fossil Beds National Monument in eastern Oregon was selected to study spatial...
