Aspen Forests, More Than Just Trees

Marc Coles-Ritchie

Aspen forests are an iconic part of our western North America landscape. In the summer their lush green leaves are beautiful and the canopy provides refreshing shade. In the fall their orange, red, and yellow leaves deliver breathtaking color. Even in winter their white trunks and leafless branches create stark beauty where we snowshoe, ski, or drive. But if you spend time inside a healthy aspen forest during the growing season you will also experience a beauty in the diverse underlying plant community.

Deep-Flow Hydroponic Culture: Copper Toxicity At 8 Μm (0.13 Ppm) In Tomato, Noah Langenfeld, Saundra Rhodes, Bruce Bugbee

Hydroponics/Soilless Media

Plants have more than 100 copper-containing proteins. About half of the Cu in plants is in the chloroplast, bound to plastocyanin, where it helps absorb oxygen radicals. Cu is considered adequate in solution at 2 to 4 μM (0.03 to 0.06 ppm). The requirement for Cu is so low that it can sometimes be supplied from contamination. The effect of higher levels is not well studied. Here we report the effect of Cu at 0, 4, and 8 μM (0, 0.06, and 0.13 ppm Cu) in tomato (Solanum lycopersicum) in a deep-flow hydroponics system.

Fire Alters Plant Microbiome Assembly Patterns: Integrating The Plant And Soil Microbial Response To Disturbance, Nicholas C. Dove, Dawn M. Klingeman, Alyssa A. Carrell, Melissa A. Cregger, Christopher W. Schadt

Aspen Bibliography

• It is increasingly evident that the plant microbiome is a strong determinant of plant health. While the ability to manipulate the microbiome in plants and ecosystems recovering from disturbance may be useful, our understanding of the plant microbiome in regenerating plant communities is currently limited.
• Using 16S ribosomal RNA (rRNA) gene and internal transcribed spacer (ITS) region amplicon sequencing, we characterized the leaf, stem, fine root, rhizome, and rhizosphere microbiome of < 1-yr-old aspen saplings and the associated bulk soil after a recent high-intensity prescribed fire across a burn severity gradient.
• Consistent with previous studies, we found that soil microbiomes are responsive to fire. We extend these findings by showing that certain plant tissue microbiomes also change in response to …

Na Lidar And Mighti/Icon Investigation On Turbopause Tidal Waves, Tao Yuan, Michael H. Stevens, Christoph R. Englert, Thomas J. Immel

Browse all Datasets

Local full diurnal coverage of temperature variations across the turbopause (~ 90 km to 115 km altitude) is achieved by combining the nocturnal observations of a Sodium (Na) Doppler lidar on the Utah State University (USU) campus (41.7?N, 248.2?E) and NASA MIGHTI/ICON daytime observations made in the same vicinity. In this paper, utilizing this hybrid dataset during summer 2020 between June 12th and July 15th, we retrieve the temperature signatures of diurnal and semidiurnal tidal waves in this region. The tidal amplitudes are similar for both components: less than 5 K below ~ 98 km but increase considerably above, up …

The 2020 National Snow Load Study, Brennan L. Bean, Marc Maguire, Yan Sun, Jadon Wagstaff, Salam Al-Rubaye, Jesse Wheeler, Scout Jarman, Miranda Rogers

Mathematics and Statistics Faculty Publications

The United States has a rich history of snow load studies at the state and national level. The current ASCE 7 snow loads are based on studies performed at the Cold Regions Research and Engineering Laboratory (CRREL) ca. 1980 and updated ca. 1993. The map includes large regions where a site-specific case study is required to establish the load. Many state reports attempt to address the "case-study regions" designated in the current ASCE 7 design snow load requirements. The independently developed state-specific requirements vary in approach, which can lead to discrepancies in requirements at state boundaries. In addition, there has …

Reviewing Tools For Evaluating K-12 Instructional Materials Through An Implementation Lens, Kristen R. Rolf, Sarah E. Pinkelman, Kaitlin Bundock

Special Education and Rehabilitation Counseling Faculty Publications

This review examined how state-created tools for evaluating instructional materials support local schools and school districts to address implementation when adopting instructional materials. We followed a priori, systematic procedures to conduct a web search and visit each state’s department of education website in search of instructional materials evaluation tools. After identifying all of the state-created instructional materials evaluation tools in the areas of English/language arts and mathematics, we reviewed the tools and coded them for evidence of alignment with the six implementation indicators defined by the Hexagon Tool (Metz and Louison, The Hexagon Tool: exploring context. Based on Kiser, Zabel, …

Management Innovations For Resilient Public Rangelands: Adoption Constraints And Considerations For Interagency Diffusion, Gwendŵr R. Meredith, Mark W. Brunson, Stuart P. Hardegree

Environment and Society Faculty Publications

Maintaining healthy rangeland ecosystems requires adaptive co-management at the landscape scale. Because the majority of western rangelands are publicly owned, it is critical that federal land management agencies work together in generating and sharing information. Promotion and communication of rangeland management innovations among agencies is one means of sharing information. Two rangeland management innovations, the Weather-Centric Restoration Tool and Interpreting Indicators of Rangeland Health, were studied in order to better understand agency adoption decisions and barriers to diffusion of the innovations across agencies. Using a mixed qualitative methodology, we interviewed land managers across the floristic Great Basin and in southeastern …

Western Conenose Bug (Kissing Bug), Zachery R. Schrumm

All Current Publications

The western conenose bug is the only species of kissing bug that is known to occur in Utah, and it is uncommon. Kissing bugs feed on the blood of vertebrates and can transmit the parasite that causes Chagas disease in humans. However, the transmission of the parasite does not occur from a kissing bug bite, but rather from the insect’s feces that can be infected with the parasite. Transmission of the parasite from the western conenose bug is less likely compared to other species of kissing bugs that exist in other areas of the United States. Prevent kissing bugs in …

Ultrasound Measurements Of Subcutaneous Fat Thickness Are Robust Against Hydration Changes, Dale R. Wagner, James D. Cotter

Kinesiology and Health Science Faculty Publications

Ultrasound is an appealing tool to assess body composition, combining the portability of a field method with the accuracy of a laboratory method. However, unlike other body composition methods, the effect of hydration status on validity is unknown. This study evaluated the impact of acute hydration changes on ultrasound measurements of subcutaneous fat thickness and estimates of body fat percentage. In a crossover design, 11 adults (27.1 ± 10.5 years) completed dehydration and hyperhydration trials to alter body mass by approximately ±2%. Dehydration was achieved via humid heat (40 °C, 60% relative humidity) with exercise, whereas hyperhydration was via ingestion …

Dissipation Rates Of Oxygen Nanobubbles In Recirculating Systems, Noah Langenfeld, Bruce Bugbee

Techniques and Instruments

Dissolved oxygen (DO) in water is essential for the metabolism of aerobic organisms in hydroponics, aquaponics, waste water treatment, and aquaculture. DO levels at or near saturation are required to prevent the development of hypoxic conditions (Wei et al., 2019). Water with saturated amounts of DO is achieved by bubbling air through a tube or air stone via an air pump. Using pure oxygen for aeration can increase the concentration of DO from 21% to 100% compared to air. Nanobubbles have diameters on the nanometer scale (10-9 m) and have extended lifetimes in suspension compared to macrobubbles (Atkinson et al., …

Understanding The Transient Nature Of Stem Doctoral Students’ Research Self-Efficacy Across Time: Considering The Role Of Gender, Race, And First-Generation College Status, Kaylee Litson, Jennifer M. Blaney, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Developing research self-efficacy is an important part of doctoral student preparation. Despite the documented importance of research self-efficacy, little is known about the progression of doctoral students’ research self-efficacy over time in general and for students from minoritized groups. This study examined both within- and between-person stability of research self-efficacy from semester to semester over 4 years, focusing on doctoral students in biological sciences (N = 336). Using random intercept autoregressive analyses, we evaluated differences in stability across gender, racially minoritized student status, and first-generation student status. Results showed similar mean levels of self-efficacy across demographic groups and across …

Future Dominance By Quaking Aspen Expected Following Short-Interval, Compounded Disturbance Interaction, Robert A. Andrus, Sarah J. Hart, Niko Tutland, Thomas T. Veblen

Aspen Bibliography

The spatial overlap of multiple ecological disturbances in close succession has the capacity to alter trajectories of ecosystem recovery. Widespread bark beetle outbreaks and wildfire have affected many forests in western North America in the past two decades in areas of important habitat for native ungulates. Bark beetle outbreaks prior to fire may deplete seed supply of the host species, and differences in fire‐related regeneration strategies among species may shift the species composition and structure of the initial forest trajectory. Subsequent browsing of postfire tree regeneration by large ungulates, such as elk (Cervus canadensis), may limit the capacity …

Community Paramedicine: A New Approach To Health In Rural Communities, Kira Swensen, Timothy Keady, Ashley Yaugher, Kandice Atisme, Emma Parkhurst, Hailey Judd, Maren Wright Voss

All Current Publications

The community paramedicine (CP) concept is becoming widely used in rural communities to assist in maintaining and improving health across economic and geographic disparities. This model utilizes highly trained emergency medical service (EMS) professionals under the supervision of a physician or other advanced practice practitioner (i.e., physician assistants and advanced practice registered nurses; Patterson et al., 2016) to provide a variety of needed health services tailored to community needs. CP has been shown to be effective in many communities and, given these positive results, should be considered in rural communities where geographic barriers limit access to healthcare (Martin & O'Meara, …

Plant Functional Groups And Species Contribute To Ecological Resilience A Decade After Woodland Expansion Treatments, Stephanie Freund, Beth A. Newingham, Jeanne C. Chambers, Alexandra K. Urza, Bruce A. Roundy, J. Hall Cushman

Articles

Woody plant expansions are altering ecosystem structure and function, as well as fire regimes, around the globe. Tree-reduction treatments are widely implemented in expanding woodlands to reduce fuel loads, increase ecological resilience, and improve habitat, but few studies have measured treatment outcomes over long timescales or large geographic areas. The Sagebrush Treatment Evaluation Project (SageSTEP) evaluated the ecological effects of prescribed fire and cut-and-leave treatments in sagebrush communities experiencing tree expansion in North American cold desert shrublands. We used 10 yr of data from the SageSTEP network to test how treatments interacted with pre-treatment tree dominance, soil climate, and time …
