Do Eastern Gray Squirrels (Sciurus Carolinensis) Use Human-Provided Cues To Increase Foraging Success In Urban Landscapes?, Aditya A. Mehta, Jeeva H. Rathnaweera Apr 2020

Do Eastern Gray Squirrels (Sciurus Carolinensis) Use Human-Provided Cues To Increase Foraging Success In Urban Landscapes?, Aditya A. Mehta, Jeeva H. Rathnaweera

Undergraduate Arts and Research Showcase

The coexistence of humans with other animals in urban and suburban areas has given rise to a spectrum of agonistic and beneficial interactions. Animals thriving in urban settings are known to exhibit superior foraging and food extraction abilities compared to their wild conspecifics. This has raised the question regarding if non-human animals can form and maintain a similar “theory of mind” to humans based on the actions they observe in their environments (Schloegl et al., 2007). For this experiment, human-made click and gaze cues were used while placing food for eastern gray squirrels (Sciurus carolinensis) located on the …


The Effects Of Gall Formation Due To Gall-Inducing Insects On Solidago Altissima’S Stem Height, Sarah Mummel Apr 2020

The Effects Of Gall Formation Due To Gall-Inducing Insects On Solidago Altissima’S Stem Height, Sarah Mummel

2020 Awards for Excellence in Student Research and Creative Activity

Gall-inducing insects are an old evolutionary member of our world, but little is known about their impact on goldenrod, Solidago altissima’s growth and development. We tested the relationship between gall diameter and stem height and the effects of gall presence on stem height. We sampled 20 random 1m2 plots along a 30 meter long transect in a goldenrod field to find rosette and ball galls growing upon goldenrod. This transect was one of five other parallel transects, totaling approximately 150 m2 of land. We measured heights of galled plants, heights of healthy nearby plants, and the diameter …

Artificial Perches As A Technique For Enhancing Tropical Forest Restoration: A Case Study From The Dominican Republic, Spencer Schubert, Ally S. Lahey, Ashley R. Weisman, Eric L. Walters

College of Sciences Posters

Recovering secondary forests on degraded agricultural lands represents a promising opportunity to offset global carbon emissions as well as increasing local biodiversity and ecosystem services. In the insular tropical forests of the Caribbean, frugivorous birds are the primary seed dispersers for most native woody plants and have a large influence on regeneration dynamics during forest succession. In 2017, we initiated an experimental forest restoration program incorporating artificial perches on private farms within the Rio Yaque del Norte watershed in La Vega province, Dominican Republic. Five restoration plots (0.15–0.25 ha) were constructed in pastures near deforested streams. In each plot, 6-12 …

Nutrient Removal Potential Of Constructed Wetlands In Grand Lake St. Marys Watershed, Stephen J. Jacquemin, Jocelyn Birt, Benjamin Strang, Conner Ewing, Bradley Axe, T. Dirksen

Lake Campus Research Symposium Abstracts and Posters

Constructed wetlands are becoming an increasingly important management tool to reduce nutrient rich agricultural runoff in the Great Lakes region. The objective of this study was to assess the removal efficiency of two constructed wetlands operating on tributaries of Grand Lake St. Marys (Prairie Creek and Coldwater Creek) located in northwest Ohio. Water samples were collected weekly during 2019 year from inflow and outflow points where they were analyzed for nutrient (nitrate-N, total phosphorus, dissolved reactive phosphorus) concentrations following standard EPA colorimetric methods. Overall, while both wetlands experienced high mean nutrient inputs (concentrations in mg/L) across both fall and summer …


Potential Of Pasture Grasses To Reduce Soil Runoff In Simulated Spring Seeding Applications, Aubrey Jaqueth, Stephen J. Jacquemin Apr 2020

Potential Of Pasture Grasses To Reduce Soil Runoff In Simulated Spring Seeding Applications, Aubrey Jaqueth, Stephen J. Jacquemin

Lake Campus Research Symposium Abstracts and Posters

Declines in surface water quality has emerged as one of the foremost environmental, social, and political issues in the Midwestern United States over the past several decades. One of the leading causes of water quality issues in this region has been linked to non-point source surface runoff of soil, nutrients, and chemicals from primarily agricultural landscapes. Surface runoff negatively affects water by facilitating eutrophic conditions and additionally, negatively impacts landscapes by reducing the organic and top soil layers leading to production declines. Thus, best management practices that focus on reducing runoff rates in agricultural acreage are a high priority. The …


Lightning Damage Stimulates Beetle Activity In A Tropical Forest, Samantha C. Vaughn, Kane A. Lawhorn, Evan M. Gora, Steve P. Yanoviak Apr 2020

Lightning Damage Stimulates Beetle Activity In A Tropical Forest, Samantha C. Vaughn, Kane A. Lawhorn, Evan M. Gora, Steve P. Yanoviak

Undergraduate Arts and Research Showcase

Disturbance alters the structure of ecological communities. Localized disturbances in tropical rainforests often create canopy gaps - patches of forest where large trees have fallen or are defoliated. Lightning is a major cause of large-tree mortality, and consequently gaps, in tropical forests. Lightning-caused gaps consist of abundant dead standing wood which likely is a predictable resource for saproxylic arthropods, specifically wood-boring beetles (Coleoptera). The goal of this study was to provide a preliminary evaluation of the beetles that are attracted to lightning-damaged trees in a tropical forest. We placed flight intercept traps in the subcanopy of 8 trees (4 struck …


Using Δ18o To Track Po4 Entering The Western Basin Of Lake Erie, Melanie M. Marshall, Gabrielle K. Metzner, Kevin E. Mccluney Apr 2020

Using Δ18o To Track Po4 Entering The Western Basin Of Lake Erie, Melanie M. Marshall, Gabrielle K. Metzner, Kevin E. Mccluney

Lake Campus Research Symposium Abstracts and Posters

Algal blooms in the Western Basin of Lake Erie are dependent upon nutrients provided by major rivers within Northwest Ohio. To develop more accurate methods of defining which of these waterways is the largest contributor, a proof of concept study is being conducted using δ18O of phosphate molecules. In the summer of 2016, under relatively low stream flow conditions, 10-20L samples of water were collected at the several major branches within the Portage River, at the mouths of the Portage, Maumee, and Sandusky Rivers, and at two locations within the Western Basin. In the spring of 2017, these collections were …


Continuous Water Quality Monitoring Platform For Grand Lake St Marys, Aaron Neikamp, Alex Lehman, Brandon Siefring, Jason Evers, Ryan M. Spicer, Shayna R. Petitjean Apr 2020

Continuous Water Quality Monitoring Platform For Grand Lake St Marys, Aaron Neikamp, Alex Lehman, Brandon Siefring, Jason Evers, Ryan M. Spicer, Shayna R. Petitjean

Lake Campus Research Symposium Abstracts and Posters

For the past decade, Grand Lake St. Marys (GLSM) has struggled to provide a stable and clean water source for the community affecting people and businesses alike. A safe level of microcystin –a toxin in the harmful algal blooms–is 20 ppb in recreational water, and GLSM has seen an excess of 82 ppb. As of now, there is no solution to continuously monitor the water quality; therefore, corrective actions are only based off intermittent samples taken by hand. A solution to this issue would be a water quality platform (WQP) that monitors parameters such as water and air temperature, conductivity, …

Are Humans Natural? Part 4: Human-Nature Relational Values Through Time, Nathan Ruhl, Sirena Pimenta Feb 2020

Are Humans Natural? Part 4: Human-Nature Relational Values Through Time, Nathan Ruhl, Sirena Pimenta

Open Educational Resources

This activity assumes students have a background in evolutionary theory, so students without such a background should have additional instruction prior to conducting this part of the activity. Consider a discussion of mechanisms that drive evolution, including genetic drift, natural selection, and gene flow. Evolution is a change in gene frequencies in a population over the course of several generations.

Genes are the genetic code controlling many individual characteristics or traits, so the frequency at which genes occur dictates, in large part, the frequency at which individual characteristics or traits exist in a population. The frequency of a gene can …

Conspecifics And Familiar Odors Alter Movement Patterns In A Land Snail, Cepaea Hortensis, Madeleine Shelton, Jeeva Rathnaweera, Perri Eason Jan 2020

Conspecifics And Familiar Odors Alter Movement Patterns In A Land Snail, Cepaea Hortensis, Madeleine Shelton, Jeeva Rathnaweera, Perri Eason

Undergraduate Arts and Research Showcase

In some animals, unfamiliarity with a place and the presence of a conspecific can change movement patterns, often altering individuals’ routes, exploration, and the directions taken. Patterns such as these can affect individual survival, and thus might be present across a wide range of taxa, although mostly vertebrates have been studied. We used a native Kentucky land snail (white-lipped globe snail, Cepaea hortensis) to investigate how snail size, familiarity and the recent presence of a conspecific affect movement of snails in a novel environment. We also tested whether presence of a familiar smell influenced movement on a 25X25 cm …


Risk Assessment And Flight Decisions In Adult Versus Juvenile Squirrels (Sciurus Carolinensis), Alex Haydon, Jeeva Rathnaweera, Perri Eason Jan 2020

Risk Assessment And Flight Decisions In Adult Versus Juvenile Squirrels (Sciurus Carolinensis), Alex Haydon, Jeeva Rathnaweera, Perri Eason

Undergraduate Arts and Research Showcase

One way to quantify a prey’s response to a predator is by flight initiation distance (FID), the distance between a predator and prey at the moment the prey flees. As perceived risk from a predator increases, FID increases. Juvenile animals typically flee from approaching threats sooner than do adults because they have less able risk assessment. However, our observations suggested juvenile squirrels might use a different tactic: foraging near refuges. We first tested whether age affected squirrels’ FID in response to an approaching human on the UofL campus, where squirrels experience high levels of interactions with humans from an early …
