How To Effectively Trap Invasive Crayfish: A Discrete Life Stage Mathematical Model, Rini Pattison

Seaver College Research And Scholarly Achievement Symposium

The red swamp crayfish is an invasive species introduced into several streams within the Santa Monica Mountains (SMM). Crayfish predation decimates native aquatic species. The Mountains Restoration Trust (MRT) has worked to remove crayfish through regular trapping in Malibu Creek.

A prior student created a crayfish life cycle model with trapping, which we expand to better predict the efficacy of crayfish removal efforts in the SMM. We separate crayfish based upon life stages and sizes. We construct and parameterize this discrete crayfish population model with and without trapping. We use literature and crayfish removal data from MRT to fit the …

How Does Vertical Hydroponic Farming Compare To Traditional Soil Farming In Terms Of Crop Yield, Energy Efficiency, And Cost?, Grace Morgan, Grace Henry, Rebecca Meenach, Jeana Odom

Student Scholar Symposium

Vertical hydroponics (hydro “water;” ponics “labor”) is a method of year-round farming that uses water in place of soil and supplies vegetables’ nutrients in a space-efficient setting. It dates back to 500 BC when it was used in the Hanging Gardens of Babylon, a wonder of the ancient world. Thousands of years later, vertical hydroponics has expanded across the globe to supply leafy greens, herbs, and grains. It is typically implemented in dense urban environments where green space is hard to come by as a form of sustainable farming. Our research seeks to answer the question “How does vertical hydroponic …

Reducing Uncertainty In Sea-Level Rise Prediction: A Spatial-Variability-Aware Approach, Subhankar Ghosh, Shuai An, Arun Sharma, Jayant Gupta, Shashi Shekhar, Aneesh Subramanian

I-GUIDE Forum

Given multi-model ensemble climate projections, the goal is to accurately and reliably predict future sea-level rise while lowering the uncertainty. This problem is important because sea-level rise affects millions of people in coastal communities and beyond due to climate change's impacts on polar ice sheets and the ocean. This problem is challenging due to spatial variability and unknowns such as possible tipping points (e.g., collapse of Greenland or West Antarctic ice-shelf), climate feedback loops (e.g., clouds, permafrost thawing), future policy decisions, and human actions. Most existing climate modeling approaches use the same set of weights globally, during either regression or …

The Kentucky Mesonet is a great asset for the Commonwealth of Kentucky in a multitude of ways, from real-time storm monitoring to building a detailed climate record. A detailed climate record is essential as causality between observations and extreme weather can be identified, making it a great tool in an evolving climate system. The climate record being developed at the 75+ Kentucky Mesonet observation stations consists of approximately 75 indices that reflect frequency, extremes, range, duration, trends of precipitation, droughts, and extreme temperatures. Calculations are done for daily, weekly, monthly, seasonal, bi-annual, and annual aggregation periods. Tools will also be …

Corrosion Prevention On Aluminum Alloy, Andrea Brenner

Symposium of Student Scholars

Aluminum alloy (Al-alloy) is a widely used metal in construction, aerospace, aviation, and other necessary fields due to its lightweight and tweakable properties. However, corrosion is inevitable on metals and alloys, and that causes millions of dollars of revenue loss every year. Therefore, we propose to research fabricating coating to prevent corrosion on Al-alloy. This study uses an iron-based metal-organic framework (MOF) and polyurethane (PU) based composite coating to prevent corrosion on the Al-alloy. The makeup of the composite material is changed by varying the percentage of MOF. In addition, a binder is also used to enhance the homogenization between …

Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl

Symposium of Student Scholars

Do chemical pollutants that persistent in the environment and bioaccumulate in the body affect human health and behavior? Could these Persistent, Bioaccumulative, and Toxic (PBT) chemicals play a role in the cause of violent crimes due to deterioration of mental and cognitive functions? In the past, Mercury, a PBT chemical, has been shown in salmon to be associated with aggression. Could similar aggression occur in humans exposed to mercury through a toxic spill? Two sources of data are utilized in this analysis. The Environmental Protection Agency’s (EPA) Annual Toxic Release Inventory publishes data on toxic releases into the environment and …

295— Biomimicry: Investigating The Active Site Model Of Lactate Racemase, Stephanie Podguski, Maisy Ross

GREAT Day Posters

Because of humans’ heavy impact on nature with industrialization and resource extraction, biomimetics, also known as biomimicry, is a study that has emerged. Biomimetics utilizes observations from nature to comprehend the principles of underlying mechanisms and apply concepts that may benefit science, medicine, engineering and the like. An area of biochemistry we are applying this to is the lactate racemase enzyme.This metalloenzyme is found in many prokaryotic organisms and catalyzes the interconversion between the two optical isomers of lactic acid. The structure of this enzyme consists of a square-planar nickel (II) ion coordinated by a histidine residue and a pincer …

Studying The Glacial Melt Of Mount Baker Using Remote Sensing (1999 - 2019), Cole Fletcher

Scholars Week

With rising temperatures glaciers around the globe are beginning to melt. Melting of large glaciers should be concerning as they can raise the present sea-level which could potentially put near sea-level urban areas underwater. We must observe the rate at which glaciers are retreating. Mountain glaciers are a good resource to observe as they do give a clear visual of how fast glaciers are retreating. This project hopes to give a good visual representation and quantitative measurement of how much glacial melt is occurring at Mt Baker in Washington, United States, in the last 20 years. This project will use …

Summer Precipitation Occurrence Effect On Two Passerine Species In Thule, Greenland, Sara E. Baugh

Celebration of Learning

Climate change is occurring at a faster rate in the Arctic than the rest of the globe, causing temperature rises at twice the rate of the global average and increased summer precipitation in the form of rain. These precipitation events are predicted to affect migratory bird species that breed throughout the Arctic. Increased occurrence of heavy rainstorms indirectly affect bird populations by impacting distribution and abundance of food supply, and directly by increasing mortality rates of juveniles. Studies conducted on bird species throughout the low Arctic regions; have shown that it is not the total precipitation of a breeding season …

Persistence Of Trace Organic Contaminants From A Commercial Biosolids-Based Fertilizer In Aerobic Soils, Travis A. Banet, Jihyun R. Kim, Michael L. Mashtare

The Summer Undergraduate Research Fellowship (SURF) Symposium

Municipal biosolids are recycled as agricultural fertilizers. Recent studies have raised concerns due to the presence of emerging contaminants in municipal biosolids. Previous research suggests that these contaminants have the potential to reside in biosolids-based fertilizers that are commercially distributed. Use of these products in urban/suburban areas may provide a pathway for these contaminants to enter ecosystems and impact human and environmental health. Soils from Purdue University’s community garden and MiracleGro Potting Mix were chosen to represent commonly used urban/suburban growth media. Triclosan, triclocarban, and methyl parabens were selected as compounds of interest for this study. A heat treated commercial …

Human Factors and Applied Psychology Student Conference

Studies have focused on cultural and gender differences based on perceptions of air pollution. Although these studies provided valuable information on cultural and gender differences on perceptions of air pollution, there have not been studies conducted regarding consumer’s perceptions on air pollution from commercial aircraft and their willingness to fly. Therefore, the purpose of this study was to examine how varying pollution levels influenced participant’s willingness to fly across two nationalities and genders.

In the study, five hundred and ninety-nine participants from India and the United States answered questions related to their attitudes toward flying on an aircraft emitting air …

Environmental Variables Affecting The Performance Of Large-Scale Solar Photovoltaic Power Plants, Parikhit Sinha

Climate Sustainability Lecture Series

The environmental sciences have been critical to identifying global environmental challenges such as climate change, but they have been less extensively utilized in deploying solutions to those challenges, such as solar energy. Environmental variables such as temperature, humidity, aerosols, clouds, soiling, and snowfall have important effects on solar PV performance, and these effects can vary regionally. The current status of large-scale solar PV deployment will be discussed along with the role of environmental variables on PV performance.

On February 12th, 2014, a sinkhole occurred at the National Corvette Museum in Bowling Green, Kentucky. The collapse happened inside part of the building known as the Skydome and eight Corvettes on display were lost into the void that opened in the concrete floor. In this region of Kentucky, known as the Pennyroyal sinkhole plain, subsidence and cover collapse sinkholes are commonly found throughout the landscape. This iconic karst region in the United States is also home to Mammoth Cave, the longest cave in the world, and thousands of other caves and karst features. Investigation of the sinkhole collapse began …

Finding Springs In The File Cabinet, Mason Johnson, Ashley Ignatius

Sinkhole Conference 2015

The Minnesota Pollution Control Agency (MPCA), in partnership with other agencies, is currently undertaking comprehensive sub-basin assessments statewide over a ten-year period. Southeast Minnesota has over 17,500 kilometers of perennial and intermittent streams, making the task of comprehensive sub-basin assessment challenging; the task is further complicated by karst geology. In the summer of 2014, a pilot project began between the MPCA and Minnesota Department of Natural Resources (DNR) to digitally preserve paper documents which capture qualitative and quantitative data about the hydrology, water chemistry, geomorphology, biology, land use and karst features of southeast Minnesota streams. The paper documents in file …

A High-Altitude Balloon Platform For Determining Regional Uptake Of Carbon Dioxide Over Agricultural Landscapes, Angela M. Bouche

2017 Academic High Altitude Conference

Interactions between the biosphere and atmosphere are an important part of the global carbon cycle, and quantifying the carbon dioxide exchanges between them is helpful in predicting the uptake of carbon dioxide from anthropogenic sources by the biosphere in the future. In the Midwestern United States, agricultural systems cover a large part of the landscape, so understanding their role in influencing the global carbon budget is crucial as anthropogenic sources of carbon dioxide grow larger. Carbon dioxide exchanges can be measured by eddy covariance at the ecosystem level (bottom-up approach) or regionally by inversion techniques (top-down approach). Here we describe …

Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes

The Summer Undergraduate Research Fellowship (SURF) Symposium

Climate change and increases in nitrogen deposition impact ecosystems globally. Projected atmospheric warming allows rain to fall in larger events with longer dry periods in between, increasing rainfall variability in many regions. Concurrently, the combustion of fossil fuels and the heavy use of nitrogen fertilizers continue to increase the availability of nitrogen globally. However, not much is known about how these global change factors, increased rainfall variability and nitrogen deposition, interact with each other to affect ecosystem functions, particularly belowground where root production contributes to soil carbon pools- an important component in regulating climate. In order to study these factors, …

Stable Isotope Composition Of Perennial Ice In Caves As An Aid To Charaterizinging Ice Cave Types, Charles J. Yonge

The International Workshop on Ice Caves

Stable isotope studies of perennial ice from western North American ice caves suggest that three main types can be defined: cold trap, permafrost, and cold zone. Some complex cave systems may comprise two or more types. While 14 caves were sampled from the region, in this study, 9 definitive sites were examined in more detail where they exemplified classic perennial ice features: massive ice, hoar frost, ice stalagmites and so on. Stable isotopes of the ice (d¹⁸O and d²H) assist in the understanding the origin of the freezing moisture, whether from direct snow (cold trap), moist …

Tapping The Apocalypse & Healing With Intention, Julianne E. Henderson Ms.

Creative Activity and Research Day - CARD

When crisis strikes, practical skills and strategies are critical to one's survival. However, one's positive mentality, relationship with and knowledge of his or her environment, and capacity for compassion when faced with an apocalyptic landscape are just as likely to boost their morale. Maintaining an optimistic consciousness assists human beings with survival, regardless of what level of adversity we face. This research project combines an important skill, which is knowing how to heal oneself naturally with what Nature provides, with the power of our consciousness to determine our success, strength, and overall capacity for withstanding the hurricanes of change.
