Effects Of Roadways On Seasonal Movement Strategies And Mate Location Success In An Imperiled Pit Viper (Crotalus Horridus), Dominic Desantis

Academic Affairs

A detailed understanding of animal movement behavior is fundamental to effective conservation and management. Within populations, a diversity of movement strategies can be displayed in search of critical resources, and these strategies are influenced by multiple interacting factors related to individuals and the environment. Mating partners are one critical resource that often serves as a prominent selective force shaping movement during mating seasons. For many large-bodied snakes, such as pit vipers (Viperidae: Crotalinae), male mate-searching movements are the primary determinant of mate location success. During this time, males incur significant risks associated with elevated movement. In an increasingly human-modified world, …

Attachment theory provides a key framework for understanding adult romantic relationships, especially for individuals with a history of childhood trauma. Early adverse experiences, such as emotional abuse and neglect, as well as broader categories of Adverse Childhood Experiences (ACEs), can disrupt attachment development, contributing to insecure attachment styles—anxious or avoidant—that influence relationship dynamics in adulthood. This review synthesizes current literature on how childhood trauma contributes to attachment patterns and emotional intimacy, trust, and relationship satisfaction in adult romantic relationships. It also highlights the role of attachment in mediating the effects of childhood trauma on romantic relationships. Finally, the review proposes …


Mitochondrial Dysfunction And Parkinson's Disease: A Critical Link, Anika J. Millar Apr 2025

Mitochondrial Dysfunction And Parkinson's Disease: A Critical Link, Anika J. Millar

Senior Honors Theses

Parkinson’s disease is a neurodegenerative disorder, caused by the damage to and death of dopamine-releasing neurons in the brain. The substantia nigra is a major region housing dopaminergic neurons and plays a critical role in motor and cognitive function. When these neurons are compromised, dopamine levels decline, leading to the development of motor and cognitive dysfunction. Current treatments include dopamine precursors, which help to replace dopamine and relieve motor symptoms. However, while there is symptomatic treatment for Parkinson’s disease, there are no preventative therapies or cures. A potential link between mitochondrial dysfunction and Parkinson’s disease has prompted further research. Investigating …

Quantifying The Decline In Avian Biodiversity: A Global Crisis And Its Implications For Environmental Education, Canaline Osaka

The International Journal of Ecopsychology (IJE)

People care about what they love—and it’s easy to love--and fall in love, with birds. The

opportunities to promote bird diversity are legion, and applicable throughout K-12 education. For example, the Eastern Bluebird needs to nest in the cavities of dead trees, a habitat drastically denuded by large scale farming—or in specialized nesting boxes. A nationwide effort to build and install these boxes has brought the population back to healthy numbers since its 1970 low point. (Once one knows what they look like, one cannot miss these roadside homes—Western Bluebirds also benefit.) Students can also engineer bird houses and deters, …
