Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...
Bighorn sheep (Ovis canadensis) were not known to live on Tiburón Island, the largest island in the Gulf of California and
Mexico, prior to the surprisingly successful introduction of 20 individuals as a conservation measure in 1975. Today, a stable
island population of ~500 sheep supports limited big game hunting...

The movement of moisture into, out-of, and within forest ecosystems is modulated
by feedbacks that stem from processes which couple plants, soil, and the atmosphere.
While an understanding of these processes has been gleaned from Eddy Covariance
techniques, the reliability of the method suffers at night because of weak turbulence....
Pacific harbor seals (Phoca vitulina richardii) are one of Oregon’s most common coastal predators, numbering between 10,000 and 12,000 individuals (Brown et al. 2005b). They consume more than 149 species or types of marine prey within the Pacific Northwest, which include a large variety of commercially important fisheries species. Despite...
Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...
Resilient water, food, and energy management strategies for an ever-growing population and changing environment depends on our understanding of water and carbon cycles from local to global scales. Fluxes of water and carbon are coupled by photosynthesis and plant transpiration cycles the largest fraction of terrestrial water from the land...
Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...
The tosylhydrazones of 2-heptanone, 4,4-dimethy1-2-
heptanone, 6-heptyn-2-one and 4,4-dimethy1-6-heptyn-2-
one were synthesized and decomposed under a variety of
reaction conditions: dry lithium and sodium salt pyrolyses,
sodium methoxide thermolyses in diglyme and photolyses of
the lithium salt in tetrahydrofuran. The saturated analogues
2-heptanone tosylhydrazone and its 4,4-dimethyl
isomer afforded the...
