Lava Heron Fishing Success: The Impact Of Water Depth, Ellen Munshower, Brianna Westendorf Apr 2018

Lava Heron Fishing Success: The Impact Of Water Depth, Ellen Munshower, Brianna Westendorf

Celebrating Scholarship and Creativity Day (2018-)

The Galápagos Lava Heron (Butorides striata sundevalli) is a small bird that is endemic to the Galápagos Islands, Ecuador. It is territorial and primarily preys on small fish. Currently, there is little research on these herons, so any information will be helpful in better understanding their ecological processes. During a biology course on the islands (July 2017), we observed the hunting patterns of herons specifically their strike patterns. We hypothesized that Lava Heron’s fishing practices would differ depending on water depth. We predicted the successful strike rates would be higher in shallower water, and herons would more likely to hunt …


Effects Of Green Led Light On Lentinula Edodes Respiration And Biomass, Jacob Hauger Apr 2018

Effects Of Green Led Light On Lentinula Edodes Respiration And Biomass, Jacob Hauger

Celebrating Scholarship and Creativity Day (2018-)

Light has not traditionally been thought to influence the growth of fungi, however, recent evidence suggests that limited exposure to green light can cause an increase of biomass production in the hyphal cells of Lentinula edodes (Shiitake Mushrooms). The dry and fresh weight, volume and respiration rates of a control group and a light-treated group of commercially-grown shiitake mushrooms were measured. Results will be presented.


Individual Variation In Physiological Training Load During A Division Iii Soccer Season, Tristen Zimmerman Apr 2018

Individual Variation In Physiological Training Load During A Division Iii Soccer Season, Tristen Zimmerman

Celebrating Scholarship and Creativity Day (2018-)

This study was performed to evaluate the effect of soccer training during a DIII soccer season on the physiological response of training load. Training load was assessed by tracking individual player heart rates during all training sessions and games. Training load was scaled for each player throughout the season and average responses were characterized for individual positions.


The Effects Of Low Dissolved Oxygen Concentrations On Diving Behavior And Lactate Accumulation In Lithobates Pipiens, Benjamin R. Thompson, Tristen M. Zimmerman Apr 2018

The Effects Of Low Dissolved Oxygen Concentrations On Diving Behavior And Lactate Accumulation In Lithobates Pipiens, Benjamin R. Thompson, Tristen M. Zimmerman

Celebrating Scholarship and Creativity Day (2018-)

Dissolved oxygen (DO) concentrations in bodies of water can differ based on geographic location, time of day, or even climate change. Because frogs acquire approximately 20% of their oxygen across the skin, decreases in DO could negatively affect diving behavior by increasing reliance on anaerobic metabolism and formation of lactate. To evaluate this possibility, we measured pulmonary and cutaneous oxygen exchange as well as blood lactate levels before and after a 30-minute dive period under both saturated DO (8.341 ± 0.042 mg/L) and low DO conditions (3.918 ± 0.597 mg/L). Although frogs diving in a low oxygen environment tended to …


Sugar Concentration In The Tree Sap Of Five Species Of Minnesota Trees, Mark Ellman, Michael Ellman Apr 2018

Sugar Concentration In The Tree Sap Of Five Species Of Minnesota Trees, Mark Ellman, Michael Ellman

Celebrating Scholarship and Creativity Day (2018-)

Tree sap can be collected from a variety of species in Minnesota, including sugar maple (Acer saccharum), box elder (Acer negundo), red maple (Acer rubrum), paper birch (Betula papyrifera), and ironwood (Ostrya virginiana). The sap of different species contain varying concentrations of sugar, important for determining the amount of sap needed to boil down into a volume of syrup. In general, previous literature has shown that sugar maples have the highest concentration of sugar, followed by red maple, birch, and box elder. The sugar concentration of ironwood is as of yet unknown. The purpose of this study was to confirm …


Calcium Concentration In Tree Sap Of Five Species Of Minnesota Trees As An Indicator Of Sugar Sand, Michael Ellman, Mark Ellman Apr 2018

Calcium Concentration In Tree Sap Of Five Species Of Minnesota Trees As An Indicator Of Sugar Sand, Michael Ellman, Mark Ellman

Celebrating Scholarship and Creativity Day (2018-)

Tree sap can be collected from a variety of species (sugar maple, birch, ironwood, box elder, red maple) in Minnesota. When the sap of sugar maple trees and others are cooked into syrup, a cloudy mixture of minerals precipitates out. This precipitate, called sugar sand, gives syrup an unpleasant taste and can clog up machinery if improperly managed. Sugar sand primarily consists primarily of calcium malate. Thus, calcium concentration can be a good indicator of how much sugar sand would precipitate out if sap is processed into syrup. In general, previous literature has shown that sugar maple sap has the …


Fast Plants And Gene X Environment Interactions For The Biology 202 Laboratory, Toni R. Gohman Apr 2018

Fast Plants And Gene X Environment Interactions For The Biology 202 Laboratory, Toni R. Gohman

Celebrating Scholarship and Creativity Day (2018-)

Phenotypic plasticity is the ability for a single genotype to produce multiple phenotypes in response to environmental variation. The phenotypic plasticity of a genotype is described by its norm of reaction, and norms of reaction for different genotypes might suggest that each is favored by a different environment. In this experiment, we established a fertility gradient and produced norms of reaction for a variety of measures of plant performance using two strains of Wisconsin Fast Plants (“Astro” and “Dwarf”). The Dwarf variety performed best at low fertility levels, while the Astro variety performed best at high fertility levels. Using these …


Analysis Of Potential Archaeal Ner Endonuclease Homologs Using Saccharomyces Cervisiae, Toni R. Gohman Apr 2018

Analysis Of Potential Archaeal Ner Endonuclease Homologs Using Saccharomyces Cervisiae, Toni R. Gohman

Celebrating Scholarship and Creativity Day (2018-)

The nuclease proteins involved in eukaryotic nucleotide excision repair (NER) have been identified and are ubiquitous for most eukaryotes, including XPF (3’ endonuclease) and XPG (5’ endonuclease). Proteins with similar structures have been identified in archaeal genomes and have been shown to exhibit endonuclease activity, but their overall cellular functions have not been elucidated. The proteins Hef1 and Bax1 in archaea are two of such proteins that are candidates for homology with the XPF (Rad1 in Saccharomyces cerevisiae) nuclease. By inserting plasmids containing archaeal genes coding for these possible homologous nucleases into Saccharomyces cerevisiae without Rad1 gene (ΔRad1) and then …


Una Solución Para La Continuidad De Cuidado Médico Para Los Latinos E Hispanos, Alexandria Daggett Apr 2018

Una Solución Para La Continuidad De Cuidado Médico Para Los Latinos E Hispanos, Alexandria Daggett

Celebrating Scholarship and Creativity Day (2018-)

En el sistema médico en los Estados Unidos, hay varias barreras al acceso adecuado, especialmente para la población latina e hispanoparlante. En adición a las barreras que tienen varios grupos minoritarios en acceder el sistema de salud, los latinos e hispanos que no hablan el inglés tienen barreras idiomáticas y culturales. El sistema de intérpretes no es suficiente para atender las necesidades de los latinos e hispanos con dominio limitado del inglés. Es necesario que el sistema sanitario use un modelo exhaustivo para servir major a partidarios, navegantes y pacientes. En esta obra, voy a discutir la importancia de la …


Behavioral Response Of Amano Shrimp With A Predatory Stimulus, Paul Flanagan, Mitchell Muske Apr 2018

Behavioral Response Of Amano Shrimp With A Predatory Stimulus, Paul Flanagan, Mitchell Muske

Celebrating Scholarship and Creativity Day (2018-)

Amano Shrimp Evasion in Response to Predatory Stimulus This study observed the physical behavior of the crustacean Caridina multidentata, more commonly known as amano shrimp, and their response when introduced to a predation-like stimulus. This research sought to understand how amano shrimp are affected by the presence of fish and possible predation. This research carries significance as it could indicate whether the shrimp are affected by the water they’re in, and if that affects their capabilities to carry out their main commercial purpose. This study specifically looks at the amano shrimp and its ability to evade predation when exposed to …
