Twenty seven modern (top 1-2cm) sediment samples from multicores retrieved from throughout coastal SE Alaska were analyzed for their organic matter content and the source composition. Total organic carbon (TOC) as well as biogenic silica (bioSi), and calcium carbonate (CaCO3) content were analyzed to evaluate the organic matter content and...
This collection of poetry explores faith and isolation while questioning the ability of language to adequately express subjective experience. Gustie has provided a deeply contemplative, though rarely completely serious, romp through the lives of others who, ultimately, are reflections of the self. The three sections of the collection establish a...
This study investigated several physiological aspects of the
water economy of the Sage Sparrow, Amphispiza belli nevadensis,as
they relate to the ability of this species to inhabit xeric desert environments.
When maintained in captivity on a dry diet without
drinking water, Sage Sparrows gradually lost weight and died. During the...
The Willamette Valley, west of the Cascade mountain range in the state of Oregon, is home to a growing number of vineyards. This rather recent, booming industry of the region has become an important component of the economy of the state’s agriculture since the late 1960’s, contributing more than $1.56...
and Effects on Pinot Noir Fruit in Oregon
Sarah K. Wright1,, Laurent Deluc, PhD2, Robert R. Martin
The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure on hepatic
pyruvate carboxylase (PC) gene expression were investigated in C57BL/6J Ah[superscipt b/b male
mice. A dose-dependent reduction of PC levels and activity occurred in animals given a
single intraperitoneal dose of TCDD in a corn oil carrier. The dose ranged from 1 to...
Zonotrichia leucophrys gambelii is a strongly migratory race
of white-crowned sparrow that exhibits a marked deposition of fat
during the vernal migratory period. The physiological basis for fat deposition is a positive energy balance which results from a photo-periodically induced hyperphagia. Simultaneously with the increased
caloric intake there is an...
The heat exchange of individuals in a foraging mixed population
of Zonotrichia leucophrys and Zonotrichia atricapilla in western
Oregon is analyzed with respect to the direction of stance and
feeding location. Values for heat gain or loss in the field were
generated from a model that estimates the equivalent black-body...
The impact of anthropogenic forcing on the probability of high mean summer temperatures being exceeded in Texas in the year 2011 was investigated using an atmospheric circulation model to simulate large ensembles of the world with 2011 level forcing and 5 counterfactual worlds under preindustrial forcing. In Texas, drought is...
