The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before
Euro-American settlement.We used the journal entries to assess the influence of humans on wildlife distribution and abundance. Areas with
denser human population, such as the Columbia...
Deforestation and conversion of native habitats continues to be the leading driver of biodiversity and ecosystem service loss. A number of conservation policies and programs are implemented—from protected areas to payments for ecosystem services (PES)—to deter these losses. Currently, empirical evidence on whether these approaches stop or slow land cover...
Floods are the most frequent natural disaster, causing more loss of life and property than any other in the USA. Floods also strongly influence the structure and function of watersheds, stream channels, and aquatic ecosystems. The Pacific Northwest is particularly vulnerable to climatically driven changes in flood frequency and magnitude,...
Unconditioned responding (UCR) to a naturally aversive stimulus is associated with defensive responding to a conditioned threat cue (CS+) and a conditioned safety cue (CS-) in trauma-exposed individuals during fear acquisition. However, the relationships of UCR with defensive responding during extinction training, posttraumatic stress disorder (PTSD) symptom severity, and fearful...
Raman scattering can be a significant contributor to the emergent radiance spectrum from the surface ocean. Here, we present an analytical approach to directly estimate the Raman contribution to remote sensing reflectance, and evaluate its effects on optical properties estimated from two common semi analytical inversion models. For application of...
Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal...
Summer streamflows in the Pacific Northwest are
largely derived from melting snow and groundwater discharge.
As the climate warms, diminishing snowpack and
earlier snowmelt will cause reductions in summer streamflow.
Most regional-scale assessments of climate change impacts
on streamflow use downscaled temperature and precipitation
projections from general circulation models (GCMs)...
Quality relationships among families and teachers in early care and education (ECE) hold
promise to nurture resilience among children impacted by adversity. However, little is known
about how adverse childhood experiences (ACEs) may also affect the interactions between
families and teachers. This study uses quantitative survey data from families (N...
Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate:coenzyme A ligase (4CL) has been reported as a
means for reducing lignin content in cell walls and increasing overall growth rates, thereby improving feedstock quality for
paper and bioethanol production. Using hybrid poplar (Populus tremula 3 Populus alba), we applied this...
Previous field-scale experimental data and numerical modeling suggest that the dual-domain mass transfer (DDMT) of electrolytic tracers has an observable geoelectrical signature. Here we present controlled laboratory experiments confirming the electrical signature of DDMT and demonstrate the use of time-lapse electrical measurements in conjunction with concentration measurements to estimate the...
