Determining Habitat Prferences of Great Egrets through Foraging Rates

College of Natural Resources & Sciences

My research project looked into determining habitat preferences of Great Egrets through foraging rates across Arcata, CA. The three habitats I chose were the Arcata Marsh, Mad River Slough, and Agricultural Fields.

Determining Iron Concentrations in Seawater using Flow Injection Analysis

College of Natural Resources & Sciences

Iron concentrations in the ocean are important for the health and success of the ocean because it is an essential micronutrient for phytoplankton. However, iron is insoluble in oxygenated seawater and so most iron precipitates and sinks out of the water column. Here we present a method to analyze these low concentrations of iron using flow injection analysis, which we built following Lohan et al. (2006).

Developing a three-dimensional culture system to improve the yield of placental mesenchymal stem cell derived extracellular vesicles

College of Natural Resources & Sciences

In this study, we developed a novel approach to produce placental mesenchymal stem cell derived extracellular vesicles (PMSC-EVs) by utilizing a three-dimensional (3D) cell culture system to potentially use in regenerative medicine applications. CELLine bioreactors are a 3D culture system that is comprised of a polystyrene scaffold, to support a high-density culture, encased in a semipermeable membrane to concentrate all proteins produced by the cells within. When conditioned medium is collected from the compartment PMSC-EVs were produced over an eight-week continuous culture. This method potentially could be used as an alternative to conventional culture methods to improve PMSC-EV yield.

Digital Dissection Table Demo

Library

Check out the library's latest simulation technology, the Digital Dissection Table on the 2nd floor to see how you can interact with high resolution images of functional anatomy and physiology to learn functional anatomy to zoology. Interact to learn biological, kinesiology, medical, and veterinary concepts and details.

Do Dabbling Ducks Forage More in the Morning or at Night?

College of Natural Resources & Sciences

My research project looked at if dabbling ducks forage more in the morning or afternoon. My hypothesis was that they would forage more in the morning than afternoon.

Do Song Sparrows Alter Song in Noisy Natural Environments?

College of Natural Resources & Sciences

This project studied the minimum song note frequencies of Song Sparrows in two different environments. Our results suggest that vocal plasticity arose as an adaptation in response to loud ocean surf, rivers, and wind.

DOC Sampling from Little River and Mad River

College of Natural Resources & Sciences

Dissolved Organic Carbon (DOC) is a fraction of organic carbon with size less than 0.2 micrometers. DOC comes from decomposed plants, bacteria, and algae. Abundant in marine and freshwater systems, it serves as the primary food source for aquatic webs. Generally, rivers have higher concentrations of DOC than the ocean does. In the estuary, a linear relationship between salinity and DOC indicates that the DOC concentration is fully due to mixing of freshwater and saltwater, and not any significant additional source or removal terms. DOC concentrations decreased from river to ocean. Scholarly articles have pointed this to be normal. Interpretation of data will continue.

Drop the Ramp

College of Arts, Humanities & Social Sciences

‘Drop The Ramp’ explores creating a landscape of the invasion on Omaha beach on D-day through immersive and intimate screenings. Sitting in the middle of the larger projection will be a smaller screen showing a war veteran, Frank Devita as he recounts a story never told about storming the beaches of Omaha. Inverting the interview footage to make it a color negative….viewers will need to view through their phones inverting their screens to view Frank as a color positive. This plays on newer generations' relation to war and how we’ve only ever experienced it through screens. It also plays on our relationships with older generations and how their stories might go unappreciated in a modern age

Effectiveness of Trailhead Signs

College of Natural Resources & Sciences

I went to three different trailheads to interview willing participants based on the information found on trailhead signs. Using this information, I was able to compile data to find the amount of visitors who looked at these signs, and which topics visitors answered most correctly.
