Precipitation Is A Strong Predictor Of Airborne Ammonia Levels., Bridger Jorgensen, Casey Olson, Connor Snow
Precipitation Is A Strong Predictor Of Airborne Ammonia Levels., Bridger Jorgensen, Casey Olson, Connor Snow
Research on Capitol Hill
USU senior Connor has lived in the Uintah Basin all his life and studies kinesiology. Senior Casey, a Cache Valley native, studies climate science and works at the Utah Climate Center. Junior Bridger, also of Cache Valley, studies nutrition science. They led and funded this project through a student grant. Casey was alarmed by the ammonia data he was collecting at the Climate Center. “I immediately began to wonder how this issue would evolve over the coming decades.” The three teamed up to take a look at how Logan’s record-breaking amount of ammonia in our air is impacting those who …
Climate Change Impacts On Atmospheric Ammonia And Implications For Human Health, Casey Olson, Connor Snow, Bridger Jorgensen
Climate Change Impacts On Atmospheric Ammonia And Implications For Human Health, Casey Olson, Connor Snow, Bridger Jorgensen
Fall Student Research Symposium 2021
According to national data Cache Valley has the highest concentrations of atmospheric ammonia in the nation. This study aims to answer the questions of whether climate variables and events such as precipitation, averaged winds, geopotential height, and teleconnections can be used to predict the behavior of pollutants and how human biology is potentially affected. Data from the Utah Climate Center shows that the 3rd yearly quartile has the highest levels of airborne ammonia due to the high levels of fertilizer use and livestock emissions in the farming industry in Cache Valley. After data analysis, there seems to be a connection …
Comparative Study Of The Microbiome Of The Native Plant Ceanothus Velutinus (Snowbrush) From Different Locations And Greenhouse Studies, Jyothsna Ganesh
Comparative Study Of The Microbiome Of The Native Plant Ceanothus Velutinus (Snowbrush) From Different Locations And Greenhouse Studies, Jyothsna Ganesh
Student Research Symposium
Climatic change is one of the biggest threats to the ecosystem and biodiversity by enhancing environmental stresses. Environmental stresses such as biotic and abiotic stresses affect plant health and reduce crop production. The rhizosphere microbiome of a plant plays a significant role in a plant's defense against various biotic and abiotic stresses. In this study, we are investigating the microbiome diversity of bulk soil, rhizosphere, and endosphere of Ceanothus velutinus, snowbrush. Ceanothus is an evergreen native plant that is usually found in dry areas and thrives well in harsh conditions. The snowbrush samples were collected from different locations 1920m, 1950m, …
Microbial Community Of The Rhizosphere Of Ceanothus Velutinus Improves The Plant's Growth And Development Under Greenhouse Conditions, Jyothsna Ganesh
Microbial Community Of The Rhizosphere Of Ceanothus Velutinus Improves The Plant's Growth And Development Under Greenhouse Conditions, Jyothsna Ganesh
Student Research Symposium
Climatic change-induced environmental stresses affect crop production. Drought is such a stress which affect crop production and landscaping adversely. Native plants are great for low water use landscaping and can adapt to the natural environment. USU Center for Water-Efficient Landscaping has released a list of native plants that can be used for this purpose. This study focuses on a native plant Ceanothus velutinus (snowbrush) which is an evergreen plant native to western North America. It thrives well in harsh conditions and can act as ornamental plant in low water use landscaping but is difficult to propagate under landscape conditions. Here, …

Climate change is causing the timing of key behaviors (i.e., phenology) to shift differently across trophic levels and among some interacting organisms (e.g., plants and pollinators, predators and prey), suggesting that interactions among species are being disrupted (1, 2). Studying the phenology of interactions, however, is difficult, which has limited researchers’ ability to zero in on changes in specific interactions or on the consequences of mismatches. In PNAS, Hassall et al. (3) use a combination of citizen science techniques to investigate the effects of climate change on dozens of specific interactions. They focus on a Batesian mimicry complex involving stinging …
Colorado River Cutthroat Trout Habitat Resistance And Resilience To Climate Change, Kate H. Olsen
Colorado River Cutthroat Trout Habitat Resistance And Resilience To Climate Change, Kate H. Olsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Government agencies and private organizations spend large amounts of public money attempting to return ecosystems to a more natural state, which have often been harmed or even destroyed as a result of modern development. Colorado River cutthroat trout, Oncorhyncus clarki pleuriticus, are a subspecies of cutthroat trout. Cutthroat trout live in the Rocky Mountains of the western United States. The population of this particular subspecies has been severely reduced by human actions, and currently only 12% of its historic populations still exist. To improve the condition of cutthroat trout, fisheries professionals and biologists are working to restore natural populations. …
Climate Change And Community Dynamics: A Hierarchical Bayesian Model Of Resource-Driven Changes In A Desert Rodent Community, Glenda M. Yenni
Climate Change And Community Dynamics: A Hierarchical Bayesian Model Of Resource-Driven Changes In A Desert Rodent Community, Glenda M. Yenni
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Predicting effects of climate change on species persistence often assumes that those species are responding to abiotic effects alone. However, biotic interactions between community members may affect species’ ability to respond to abiotic changes. Latent Gaussian models of resource availability using precipitation and NDVI and accounting for spatial autocorrelation and rodent group-level uncertainty in the process are developed to detect differences in seasons, groups, and the experimental removal of one group. Precipitation and NDVI have overall positive effects on rodent energy use as expected, but meaningful differences were detected. Differences in the importance of seasonality when the dominant group was …
