Undergraduate Research

 

 Recent undergraduate research projects conducted in the biology department include: 

• Identification and origin of exotic species of seaweeds using DNA sequence comparisons.
• Using molecular genetic tools to identify extremophile bacteria from deep in Arkansas’s Blanchard Caverns.
• Studies of non–native species of invasive trees and shrubs that occur naturalized in Arkansas, their ability to become established in the local flora, and what factors influence this process.
• Tungoil tree (Aleurites fordii Hemsl.) (Euphorbiaceae) new to the Arkansas flora.
• Negundo chaste tree (Vitex negundo L.) (Verbenaceae) new to the Arkansas flora.
• Analysis of proteins and isoenzymes of Limax species by polyacrylamide gel electrophoresis.
• Distributional records of Ambystoma talpoideum in southwestern Arkansas.
