There is a growing consensus that anthropogenic warming will impact soil organic matter (SOM). Globally, soil contains 2-3 times more carbon (C) than plants, and like plants, temperature induced change of SOM could have significant climate repercussions. Although, the majority of warming experiments have increased day and night temperatures equally,...
There is reasonable expectation that climate warming will accelerate the hydrologic cycle, resulting in greater evapotranspiration (ET) and reduced groundwater recharge (R) (or stream flow). Though qualitatively intuitive, quantifying these potential shifts in water budget partitioning is a contemporary challenge in hydrology, because the linkage between ET and R is...
The purpose of this study was to test, by means of
a controlled classroom experiment, the effectiveness of
an experimental method involving the introduction of
regular dictation of unpracticed material beginning with
Lesson 25 in the Gregg Shorthand Manual Simplified,
Second Edition, by Gregg, Leslie, and Zoubek.
The study involved...
The potential impact of projected climate warming on the terrestrial hydrologic cycle is
uncertain. This problem has evaded experimentalists due to the overwhelming challenge of measuring the
entire water budget and introducing experimental warming treatments in open environmental systems. We
present new data from a mesocosm experiment that examined the...

Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...
As GIS becomes more prominent in academic classrooms at all levels of education, the subject of geography and its related disciplines can be approached with a geospatial technology perspective, using new tools and lesson plans. The implementation of Google Earth in classrooms is just one example of this. Research was...
