Environmental crime around the world, such as trafficking in illegal timber, is directly related to political instability. Traffickers exploit weak, fragile, and chaotic political circumstances to illegally extract high-value commodities, challenging the extent to which conservation goals are achievable in resource rich developing countries. Rosewood is the largest traded endangered...
Methane derived authigenic carbonate (MDAC) precipitation occurs within marine sediments as a byproduct of the microbial anaerobic oxidation of methane (AOM). While these carbonates form in chemical and isotopic equilibrium with the fluids from which they precipitate, burial diagenesis and recrystallization can overprint these signals. Plane polarized light (PPL) and...
The purpose of this study was to determine whether Alexander Astin's
Theory of Student Involvement could be applied to an academic experience in an
overseas setting. Using data collected from the program evaluations of 79 students
who had participated in the Oregon University System exchange program in Lyon,
France during...
Site preparation treatments are often used prior to the planting of clearcut
forest lands to improve planter access and to increase the number and quality of
planting spots. Most mechanical site preparation treatments alter the
configuration and material composition of surface soil materials, and can have
marked effects on soil...
Glutamine synthetase in the embryonic chick neural retina
shows a 50 fold increase in activity between the 16th and 17th day of
embryonic development. This increase in enzyme activity results
from de novo enzyme synthesis thus making it a useful marker of
differential gene expression. A precocious rise in activity...
The Altar Valley is an important working landscape that supports biodiversity and vulnerable species in Pima County, Arizona (Huckelberry 2000). This semi-desert grassland, alluvial valley and 713,807-acre watershed composed of 39 subbasins serves as an aquifer to a portion of southwestern Tucson. This region of Southern Arizona has been identified...
This investigation consisted of two parts: A. stability, B.
bioavailability of vitamin B₆ in wheat. Three variables; whole wheat
flour (WHW), white flour (W) and W enriched with vitamin B₆ (WB₆)
were tested.
Stability of vitamin B₆ during bread making and storage of
bread and flour was determined. Bread was...
As global temperatures continue to rise there has been an increase in forest fire frequency and severity. With larger areas of forest being burned it is increasingly important to understand how forest fires effect snow processes. Previous research shows that burned areas will accumulate more snow and that this snow...
