Applications of Drone and Ground-Based Photogrammetry in Geoscience Research in Southern Utah.
Three-dimensional analysis of geologic structures and terrains using aerial and ground-based photogrammetry techniques is revolutionizing the geosciences. With the drastic increase in affordable unmanned aerial vehicles (UAV’s), high-resolution photogrammetry software, and survey grade GPS instruments, three dimensional documentation and analysis is beginning to replace some traditional field methods. We use UAV’s in southern Utah for a variety of geoscience projects including Quaternary landslide assessment, structural geology studies, stratigraphic architecture, and stream channel analysis. Drones have allowed us to study and access remote locations and cliff outcrops that were previously inaccessible. Once drone or ground-based data is collected, images are processed using a variety of open-source or professional photogrammetry products. In recent years, a variety of software’s have been developed to visualize and analyze three-dimensional models. In addition to three-dimensional models, photogrammetry software’s have a host of outputs including digital terrain models (dtm), digital surface models (dsm), and orthomosaics. Advances in machine learning have enabled automatic point-cloud classification, which allows for calculation of feature type abundance and enhanced imagery analysis.

Investigating the Light-Absorbing Properties of Dipyrroles common to Bilins
Pigments in plants give us a wide variety of color. They are very beautiful at times, but also serve a more practical purpose for the plants. The dark green visible in almost all plants and algae serve the purpose of collecting light for photosynthetic processes. These green pigments are made of certain molecules called tetrapyrroles. In this project we aim to dissect a certain tetrapyrrole that forms bilins (commonly found in algae) and observe the light absorbing properties of a smaller “building block” that forms this pyrrole chain called a dipyrrole. We will perform NMR spectroscopy, mass spectrometry, gas chromatography, and IR spectroscopy on said dipyrrole compound, in conjunction with previous found data, to discover the light-absorbing properties in order to help us more fully understand what makes the larger natural pigment so efficient at capturing sunlight.

Chemical and Sedimentation Changes from Crow's Creek to Coal Creek
Coal Creek, the primary water source for much of Iron County, is markedly different from other water sources originating from Cedar Mountain due to its significant lack of biodiversity. One of the suspected contributing factors to this is the sedimentation due to runoff from snowmelt during the late winter and early spring months. This research characterizes these sedimentation changes.

Crows Creek is a tributary to Coal Creek and, unlike Coal Creek, has normal biodiversity. It does, however, have a significantly higher chloride concentration than other tributaries to Coal Creek. The creek runs adjacent to Highway 14 for a number of miles, and it is suspected that the chloride concentration might be influenced by road salt or other anthropogenic sources. Sedimentation, chloride, and sulfate concentrations along Crows Creek and near some its tributaries will be tested to determine if these are being influenced by the construction and maintenance of Highway 14.

The data from this research will add further information to understanding the limited biodiversity of Coal Creek.

Using chlorophyll concentrations, sessile bacteria concentrations, and chemical composition to identify factors affecting the biodiversity of Coal Creek
Coal Creek, which originates from the Cedar Breaks/Ashdown Gorge Drainage Basin and flows through Cedar City, has very low or no biodiversity and biomass present. Some of the tributaries of Coal Creek have been found to have some living organisms. This raises the question as to why the main creek does not support life. Since the fall of 2012 collection and analysis has been performed on hundreds of samples to determine the concentration of total metals, dissolved metals, anions, chlorophyll and more. We are currently trying to analyze this vast amount of data and collect additional meaningful samples to further identity trends. Furthermore, we are investigating the possibility of variances in sessile bacteria, which allow algae to adhere to rocks, as a factor to explain this lack of biomass. The results of our analysis will be presented to explain the lack of biodiversity and biomass in Coal Creek.

Nutritional Analysis of Eggs from Hens with Varied Diets
Backyard chicken flocks have become an increasingly popular choice for many American families. From a few hens housed in a simple coop, a family could have fresh, ethical, sustainable egg production. The benefits of raising your own egg producing hens are many. Firstly, backyard hens are very efficient at consuming food waste as a part of their diet. Rather than throw away leftovers and food prep scraps, hens are happy to turn them into fresh eggs. Also, hens raised in a backyard setting will undoubtedly have a greater quality of life than commercially raised caged hens.

The question we are asking is as follows: How do different housing arrangements and diets change the nutritional content of the eggs produced by hens, if at all? Research has been done in this field, but not extensively in a "backyard flock" type setting. It can be said that backyard flocks are more ethical and efficient than commercially raised eggs, but are they more healthy as well?

We have establish two different flocks. One with a stationary coop, without access to grass, and one with a mobile coop which models a "free range" lifestyle that some people may provide for their backyard flock. Both flocks have equal access to both chicken feed and food scraps. Analysis is being performed on egg white content, egg yolk content, and egg shell thickness in addition to the mass of each egg.

A Biodiversity Survey of Southern Utah Reptiles
Southern Utah fauna is comprised of a wide assortment of organisms from small mammals and lizards to deer and snakes. There are over 600 animal species in Utah with about 200 of them residing solely in the south. The purpose of this study is to conduct a preliminary population survey of reptiles in southern Utah. There are no published, comprehensive surveys of reptile habitat usage in southern Utah. In order to gain a broader understanding of the species living in the area, camera traps will be used to observe local reptilian species and estimate the herpetological biodiversity and habitat usage of Three Peaks Recreation Area, Quichapa Lake, and Old Iron Town. Each area is in a different geographical zone providing a rounded view of the animals living around 6,000 feet in elevation. Three Peaks is in the pine/oak belt, Quichapa is surrounded by grassland, and Old Iron Town is in the pinyon/juniper belt. We will set up 4 camera traps in each location. Photos will be collected weekly and analyzed for species type present. Walking surveys will also be conducted weekly in each location to assess the different varieties of herpetological species present.

A Structural Comparison of Isozymes with Widely Varying Optimal Temperatures
We aim to compare the structural and functional differences between a hyperthermophilic isozyme and its thermophilic and non-extremophilic counterparts. Isozymes are enzymes with a different sequence and structure while catalyzing the same enzymatic activity. Each enzyme operates at an optimal temperature and pH, and these optimal conditions frequently vary in isozymes found in different organisms. The unique amino acid sequence of a given protein and its larger-scale structure are important factors for its stability and function under its uniquely preferred conditions. Our experiments are focused on determining the x-ray crystal structure of a hyperthermophilic enzyme, and comparing it to known structures of other isozymes that are optimally active at much lower temperatures. These structural comparisons will allow us to investigate structural details that underlie the stability and function in such extreme conditions.

Evolution of Wood Warbler (Parulidae) Song
The Parulidae, or Wood Warblers, is a family of birds found in the Americas. The song behaviors vary among species, particularly in repertoire size (i.e., how many unique song types each individual sings), the context in which different song types are sung, and whether one or both sexes sing. The variation in these traits could have been affected by variation in morphology (i.e., beak size and mass), habitat, or migratory behavior. To test these relationships, we collected data on these characteristics from the literature and mapped them using a published phylogenetic tree of 115 species in this family (Lovette et al. 2010). We also measured the frequency and modulation of archived songs using Raven bioacoustics software. Using these data, we will produce analyses to formulate and test new hypotheses on the evolution of song in this group and publish an updated review.

Genetic analysis of diatoms in streams affected by the Brian Head Fire
Diatoms are single-celled organisms that live in water, and can provide information about water quality. We wanted to know how the 2017 Brian Head Fire affected stream quality in southern Utah, but diatom morphology is difficult to learn in a short period of time. However, diatoms can be identified from their DNA even without training in morphological analysis. We collected diatoms from 4 streams within the watersheds affected by the Brian Head Fire then extracted DNA from all the diatom communities. We used Next Generation Sequencing to identify over 14,753 thousand operational taxonomic units (OTU) associated with known diatom species, genera, and families. To look for patterns associated with effects of the fire, we sorted these data by abundance at each site and level of taxonomic classification (species, genus, family, order, etc.). Our work demonstrates the wide variety of diatoms that live in Utah’s streams, as well as the number of diatom species for which genetic information has not been uploaded into world wide genetic databases.

Impacts of the Brian Head Fire on the Freshwater Macroinvertebrates of the Markagunt Plateau (2016-2019)
In the summer of 2017, a fire started near Brian Head in Iron County, Utah burned more than 70,000 acres of coniferous forest on the Markagunt Plateau. We measured the effects of this fire on the macroinvertebrate fauna in three streams that run through and adjacent to the burn area. Samples were taken from Mammoth, Castle and Lowder Creeks during the fall and winter of 2018/2019. We were able to compare these data with a pre-fire study done in the same streams in the fall of 2016. We found a decrease in diversity for most taxa sampled. Future sampling will continue to monitor the recovery of these streams.

Importance of Collaborative Skills in the Workforce
Collaborative skills are vital in the workforce. Knowing how to communicate, work effectively as a team, and problem-solving are skills essential in nearly all work environments. The Forest Inventory and Analysis (FIA), the University of Nevada, Las Vegas (UNLV), and Southern Utah University (SUU) have worked together to create a virtual collaborative environment through projects like DATIM, which is an online database of collected data on the United States’ forests. In order for the FIA, UNLV, and SUU to collaborate effectively, tools such as shareable drives and calendars, group calls and meetings, and communication skills are vital. However, one’s personal collaborative skills are often not discussed. What skills are needed for students to be prepared for collaboration in the workforce? Through this project, we will review the skills that are essential to effectively work in a collaborative environment, and key methods to have a successful virtual team.

Marine Species Preservation
The human race is having many negative impacts on marine species. Not only are animals being threatened, but also oceanic plants and microorganisms. Such negative impacts include the endangerment, extinction, and overall decline of the organism's health and natural well-being. The Endangered Species Act of 1973 was put into place with the intention of stopping impacts like these from progressing to fatal outcomes, but there are problems with the Act in and of itself. If this continues, humanity will end up ruining the entire oceanic biome and lose the beneficial natural resources the “Big Blue” provides for us. In order to preserve our planet for the generations to come, we as a society need to make a conscious effort to conserve our precious oceans and their inhabitants.

Perception of Educational Videos Based on Narrator’s Gender
As research assistants in the Outdoor Engagement Center, we work in cooperation with the Forest Service on the development of the DATIM database, which contains vegetation inventory data collected by the Forest Service. We have been tasked with compiling a training module for this application to assist both government workers and the general public. Research conducted by Springer Science & Business Media B.V. (2012) shows that more men have been employed as salesmen, radio announcers, and sports commentators than women. It can be argued that because men tend to have lower pitched voices they are generally perceived as easier to understand and therefore more effective in the areas of selling products and narrating events.
This research project builds upon the findings of Springer Science & Business Media B.V. (2012) by examining how the voices of men and women differ in their perceived effectiveness in communicating information through video narration. To determine the perceived effectiveness of communication, a group of participants viewed a training video and were assessed on their understanding of the information. Half of the participants were instructed to watch a video from the DATIM training module that was narrated by a man, while the other half watched a video narrated by a woman. Participants filled out a questionnaire that assessed their understanding of the content. Results were compiled to determine whether women’s or men’s voices were easier to understand. The efforts of this research can then be applied to many different aspects of technology and learning, such as future production of instructional videos in our collaborative project.

Possible New Species of Sea Spider Discovered in the Midwaters of Monterrey, CA
Sea spiders are a relatively poorly understood group of invertebrates found throughout the entire world's oceans and seas. They can be relatively small (1mm) to extremely large (70cm). 3 specimens (1 adult male, 1 adult female, and 1 male juvenile) were collected from midwaters just off the coast of California in the Monterrey Submarine Trench. Their characteristics were observed and determined to all belong to the Genus Pallenopsis and the Subgenus Bathypallenopsis. We compared the morphological features of these 3 specimens to each other and to other similar species. These features were photographed as well as illustrated. We found that the male adult and juvenile likely constitute a new species and that the female may additionally be its own species. Further work is needed to determine the case for the female, but it is certain that there is at least one new species. The closest match to these species is P. cornea, which lacks the same spine arrangement on its ovigers and has other characteristics that make them separate.

Robinson Helicopters Safety
Have you ever thought about flying or have flown in a helicopter that people say it is not the safest helicopter? If so, you have probably heard about Robinson Helicopters. They are a helicopter that was designed to be the best low cost helicopter. Just because they are low cost does not mean they are less safe, it just means the pilot has to be more aware of the aircraft and their surroundings. Here are some accident reports and surveys to prove my point.

Significance of Quichapa lake for Migratory Birds
Quichapa Lake is an ephemeral body of water that is also the most biodiverse area for birds in iron county. Many bird species stop at the lake during critical times of migration. We have monitored the lake in order to better asses this diversity during peak periods of migration and also compared our results with the more extensive eBird database. Several species have been shown to rely on Quichapa during these periods.

Survey of Coleopteran species of Spring Creek Canyon
A study of coleopteran species found in Spring creek Canyon in Southern Utah. The study aims to use different colored pitfall traps as a means of collecting a variety of different species found in Spring Creek Canyon near New Harmony, Utah. This area’s coleopteran species are not well documented, therefore this area was determined a suitable area for research. It was hypothesized that different species of beetles would be attracted to different colored pitfall traps. The study provides a better look into Southern Utah’s beetle fauna and their behaviors.

The effect of urbanization on genetic diversity in southern Utah ant populations
Genetic diversity is critical to a species's survival and the ability to adapt to changing environments. Conservation geneticists can use genetic diversity for various species in a habitat to determine the overall health. With this information, conservation geneticists can prevent extinction and improve population viability. Ants (Formicidae) are tiny, invertebrate omnivores found all around the globe and are considered to be good indicators of ecosystem health. Our main goals were to characterize the population genetic structure and to investigate the effect of urbanization on genetic diversity in southern Utah. Samples were collected throughout Cedar City (Canyon Park, Lake at the Hills, and Main Street), and outside of Cedar City (SUU Mountain Center and Three Peaks Recreation Area). DNA was extracted with Qiagen's DNeasy Blood and Tissue Kit and amplified at 10 previously characterized microsatellite loci. Genetic diversity will be compared between urban (Cedar City locations, rural (SUU Mountain Center), and mixed use (three Peaks Recreation Area) lands to see if urbanization negatively affects ant biodiversity, potentially decreasing ecosystem health.

Distribution and microbial use of molybdenum in soils west of Milford, UT
Our study looks at molybdenum concentrations in soil, and how molybdenum is being used by soil microbes and plants. Molybdenum is an essential component of nitrogenase, a nitrogen-fixing protein found in soil bacteria, as well as in other proteins important for sulfur and nitrogen cycles and for chemical reactions of small metabolites. In environments rich in organic matter, molybdenum is bound and retained by compounds made by plants, bacteria, and fungi. Our study site, just northwest of Milford, Utah, is in the area of outflow from a tungsten mine. Initial surveys found variable
molybdenum concentrations over an area of about six square miles, with at
least one small spot of much higher concentration rising and falling over about 0.2 miles. The ecology of our study site is much different than areas previously tested in that the main plants are widely-spaced sagebrush and occasional clumps of grasses. In some areas, the soil surface is covered with black cryptobiotic crust. In our previous work, we surveyed metal concentrations relative to sage bushes. Our current proposal includes comparisons of cryptobiotic crust with the underlying soil and amplicon sequencing to identify organisms in the cryptobiotic crust.

An Exploration in General Relativity with the Great Basin Observatory
In 1915, Einstein completed his famed theory of general relativity. This theory explains the connection between space and time (space-time) and describes the behavior of gravity on a universal scale. One of the effects of gravity is that it is able to bend space-time in such a way that light follows the curvature of space. Light curves around super-massive bodies in space in a way that an object behind the massive body can be seen. This phenomenon is known as gravitational lensing. SUU students have access to the Great Basin Observatory (GBO), which houses a 27-inch remote telescope and is located in Great Basin National Park. We explored the ability of the GBO to detect gravitation lensing events with quasar systems. In our presentation, we will discuss our methods and unveil our findings.

Removal of Suspended Solids in Coal Creek for Efficient Aquifir Recharge
Coal Creek plays a large role in providing water for Cedar City and many of the surrounding communities. Any unused water will eventually end up in Lake Quichapa, where it evaporates off. The Water Conservation Board of Cedar City previously intended to filter the water in Lake Quichapa as a water source when needed, but its salinity and sedimentation concentrations were found to be too high for feasible filtration. The solution was to create sedimentation channels where the water from Coal Creek would be slowed down, allowing the majority of the sediment to settle out, then utilizing that water before it reaches Lake Quichapa. This research is to test the efficacy of this new system by measuring the sedimentation concentration at the end of these sedimentation channels.

Visitor Satisfaction Levels at Southern Utah National Parks as the Number of Visitors Increases
This study investigates the visitors’ satisfaction levels to find out if satisfaction levels were decreasing due to the increased visitation levels at southern Utah national parks, which had experienced double digit visitation increases the past two years. The parks included in this study are Arches National Park, Bryce Canyon National Park, and Zion National Park. Surveys were collected from visitors to these three parks on September 5, 2015 (the Saturday of Labor Day weekend) and on September 19, 2015 (a Saturday two weeks later) to examine the different satisfaction levels of very busy and less busy time frames. The results of this study revealed that the percent of visitors that were either satisfied or very satisfied were comparable for the two dates, but the percent of very satisfied visitors was lower for the holiday time frame. Common park features that drive visitor satisfaction were identified. Steps that can be taken to assist visitor satisfaction were also identified.

Concentrations of Pesticides in Local Honey
Recently, the honey bee population in Utah has been declining. Reasons for this include stress, poor nutrition, and exposure to pesticides. To better understand the effects of pesticides on bees, and the honey they produce, we analyzed honey samples from local Southern Utah beekeepers. We developed a method to analyze the concentrations of common Southern Utah pesticides present in the honey samples. Our method included use of the Gas Chromatography-Mass Spectrometer(GCMS). Our method and results will be discussed in our presentation. Experimental results will contribute to the research investigating the effects of pesticides on honey bees.

Cations in Coal Creek
When an atom gains or loses an electron, it becomes an ion. Positively charged ions are called cations. There are many sources of cations in our natural waters. As natural waters move closer into town, they are exposed to an increase in foot traffic, use of fertilizers, and salts from roadways during winter months. All of these can cause an increase in cation concentration. Accordingly, we are interested in how the cation concentrations fluctuate with time. To accomplish this, samples from Coal Creek will be obtained at specific locations along the creek daily. These samples will then be analyzed using Flame Atomic Absorption Spectroscopy. In addition to these results, data from years past will be compared to see if any trends present themselves. All findings will be delivered at the presentation.
