Techniques And Trials In Pteridophyte Conservation And Cultivation, Jessica Bartel May 2024

Techniques And Trials In Pteridophyte Conservation And Cultivation, Jessica Bartel

Senior Theses and Projects

With the progressive nature of climate change conditions globally over the past century, there has been increasing focus on conservation of all species, but particularly those already endangered. Over 12,000 species of ferns live on Earth, and they do not produce seeds, so an investigation into their spores and how they reach maturity will allow us to preserve more genetic material in the future for these species. As a result, we investigated ex situ conservation and survivability of in vitro cultured gametophytes of within the genus Dryopteridaceae through herbarium sample germination rates across samples representing a wide age range ( …


Under The Microscope: Painting From Histology, Meg Smith Apr 2021

Under The Microscope: Painting From Histology, Meg Smith

Senior Theses and Projects

My goal as an artist is to create paintings which explore the intersections of biology, philosophy, aesthetics, and personal experience. I want to challenge the viewer to engage with their own anatomy and physiology on a microscopic scale. I also aspire to communicate my sense of awe and wonder at the structures and mechanisms of life on every scale, from the cellular to the cosmic.

I am deeply interested in how physiological processes generate the human experience

—I became a neuroscience major because I was interested in the mechanisms of sensation and perception. My love of histology—the study of the …


The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl Apr 2020

The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl

Senior Theses and Projects

Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ. To …
