The Decline In Monarch Butterfly, Danaus Plexippus, Populations: An Example Of The Global Threat To Biodiversity, Olivia Sidoti
Honors Projects
Biodiversity encompasses the variety of all life on Earth and how these aspects of nature interact with each other. To have stable and abundant biodiversity, vast amounts of species and organisms are required within an ecosystem. As a result of the increase in negative impacts of human activities and behaviors on the health of nature, biodiversity has been decreasing. An example of the decrease in biodiversity is depicted by the recent decline of the monarch butterfly species. The monarch butterfly is an iconic North American insect that is experiencing a decline in its population due to threats such as deforestation, …

An Analysis On The Capacity Of Visual Art To Promote Conservation Efforts, Devi Bell
Honors Projects
In recent decades, we have become more aware of the ways in which anthropogenic actions are harming Earth’s climate, ecosystems, and overall stability. Scientists generally agree on the urgency of our situation, yet the public may find difficulty in comprehending the multitude of information on it. This study aims to educate the public on biodiversity loss and related ecological issues in Ohio by discussing these topics through the medium of visual art. Five pieces involving different scientific subject matter and art mediums were created and displayed for participants to view. Participants completed two surveys, one before viewing the art and …

To Hum Or Not To Hum: Analyzing And Provoking Sound Production In The American Lobster (Homarus Americanus), Renske Kerkhofs
Honors Projects
American lobsters (Homarus americanus) produce humming sounds by vibrating their carapace. These sounds have a fundamental frequency on the order of 100 Hz, with multiple higher harmonics. Though I found no relationship between lobster carapace length and hum frequency, I observed sounds similarly structured to hums but with frequencies an order of magnitude higher, suggesting that lobsters may use a wider range of sounds than previously thought. Using laser vibrometry, I was able to pick up high frequencies of carapace vibration that were similar to those I observed on sound recordings. Lobsters seem to hum most readily when …
