Describing The Effect Of Thin Layer Sediment Placement On Coastal Microbial Communities Using Foraminifera Diversity, Elizabeth B. Billings May 2022

Describing The Effect Of Thin Layer Sediment Placement On Coastal Microbial Communities Using Foraminifera Diversity, Elizabeth B. Billings

Senior Honors Projects

Salt marshes are rich ecosystems that play an important role in aquatic food systems and prevent erosion while also providing essential habitats for wildlife. Climate change has resulted in rising sea levels and erosion of these coastal wetlands. Thin Layer Sediment Placement (TLP) is a restoration effort being implemented to mitigate the effects of climate change on coastal ecosystems. The TLP process raises elevation of the marsh and provides substrates for vegetative growth by spraying dredged sediment over existing marsh. The impacts of TLP on microbial populations is not widely understood, therefore metrics are required to study the effects of …


Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, Elizabeth Saraf May 2021

Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, Elizabeth Saraf

Senior Honors Projects

Since their first recorded occurrence in 1859, Pelagic Red Crabs (PRC; Pleuroncodes planipes) have experienced increased frequency of episodic mass stranding events in the Eastern Pacific Ocean. PRC’s are transported over 1,000 km northward of their central domain from the coast of central Baja California, Mexico. They have been reported by the thousands on the beaches of central and southern California. Their presence influences the surrounding ecosystem and commercial fisheries because they are nutritional prey items and large predators change their diet to incorporate PRC’s when they are available. Seasonal coastal currents and the California Undercurrent transport warmer waters …

Exploring the Effects of Hypoxia on Sulfate Reducing Anaerobes

Annaliese K. Jones

Sponsor: Bethany Jenkins, Cell and Molecular Biology

As a student about to graduate with a degree in Biological Sciences, I find myself faced with the need to find my own independent research interests and scientific voice. As a result of my interests in the fields of both microbiology and ecology, I am drawn to questions surrounding the role and behavior of microorganisms in the environment. With climate change being an issue capturing the attention of a large portion of the scientific community, I have chosen to focus my …
