The middle Deschutes River between Bend, Oregon and Lake Billy Chinook typically experiences critically low flows during the irrigation season. Commercial agriculture in the North Unit Irrigation District and Central Oregon Irrigation District is one major user of Deschutes River water. The overall objective of this research was to estimate...

The purpose of this dissertation was to contribute to understanding teachers’ experiences as facilitators of class meetings and the supports that can affect their facilitation. Chapter 2 is the manuscript, Maximize the Benefit of Class Meetings: Facilitating the Class Meeting as a Therapeutic Group. It was a conceptual article on...
Six early to middle Tertiary geologic units crop out in the
Saddle and Humbug Mountain area. They include the late Eocene to
early Miocene Oswald West muds tones, the lower Silver Point and
the upper Silver Point tongues of the middle Miocene Astoria Formation,
and the middle Miocene Depoe Bay...

The Rock Creek area consists of 53 square miles located in
the eastern foothills of the Pioneer Mountains, Beaverhead County,
Montana. Approximately 8, 500 feet of late Paleozoic and early
Mesozoic contact-metamorphosed sedimentary rocks and late Mesozoic
sedimentary rocks are exposed in the area of study.
Most of the late...

Changes in soil C and N pools following wildfire are
quite varied, but there is little understanding of the
causes of the variation. We examined how the
legacies of prefire ecosystem structure may explain
the variation in soil trajectories during the first
decade following wildfire. Five years prior to
wildfire...

Ecological restoration programs often attempt to maintain or enhance ecosystem services (ES), but fine-scale
maps of multiple ES are rarely available to support prioritization among potential projects. Here we use agency
reports, citizen science, and social media as data sources to quantify the spatial distribution of five recreational
elements of...

Litter decomposition is a keystone ecosystem process impacting nutrient cycling and productivity, soil properties, and the terrestrial carbon (C) balance, but the factors regulating decomposition rate are still poorly understood. Traditional models assume that the rate is controlled by litter quality, relying on parameters such as lignin content as predictors....

In the future, Earth will be warmer, precipitation events will be more extreme, global mean sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes will also occur at an accelerated rate as developed areas increase in size and population density. We now...

• Premise of the study: The dramatic advances offered by modern DNA sequencers continue to redefine the limits of what can be accomplished in comparative plant biology. Even with recent achievements, however, plant genomes present obstacles that can make it difficult to execute large-scale population and phylogenetic studies on next-generation...

Marine sponges are vital components of benthic and coral reef ecosystems, providing
shelter and nutrition for many organisms. In addition, sponges act as an essential carbon
and nutrient link between the pelagic and benthic environment by filtering large quantities
of seawater. Many sponge species harbor a diverse microbial community (including...

Background: Few studies examining the associations between long-term exposure to ambient air pollution and mortality have considered multiple pollutants when assessing changes in exposure due to residential mobility during follow-up.
Objective: We investigated associations between cause-specific mortality and ambient concentrations of fine particulate matter (≤ 2.5 μm; PM₂.₅), ozone (O₃),...
This study details the use of printing and other additive processes to fabricate a novel amperometric glucose sensor. The sensor was
fabricated using a Au coated 12.7 μm thick polyimide substrate as a starting material, where micro-contact printing, electrochemical
plating, chloridization, electrohydrodynamic jet (e-jet) printing, and spin coating were used...

The use of in situ measurements is essential in the validation and evaluation of the algorithms that provide coastal water quality data products from ocean colour satellite remote sensing. Over the past decade, various types of ocean colour algorithms have been developed to deal with the optical complexity of coastal...
