Two undergraduate students will serve as research assistants in ongoing projects in the laboratory.  Each will assist with studies involving mice (feeding, breeding, etc) and tissues.  There will be the opportunity to learn various biochemical and molecular biology lab skills, including tissue culture.  Students must major in biochemistry or a related STEM field.  Preference will be given to students interested in pursuing advanced training in biochemistry post baccalaureate.

The export of DOC from the Sand Hills may have major implications for downstream water quality. Recent studies have shown an inverse relationship between organic carbon and nitrate across a wide range of environments (Taylor and Townsend, 2010), including streams draining a broad range of terrestrial settings. We hypothesize that water originating in the Sand Hills is relatively low in nitrate due to sufficient DOC supply.

This project focuses on enhancing diagnosis and diagnostic testing for respiratory and ocular pathogens of cattle and enteric pathogens of swine.  The student would work to develop and validate proteomic and molecular diagnostic techniques including MALDI-TOF Mass spectrometry, Real Time PCR, and other immunodiagnostic tools.  A student with an interest in microbiology and/or veterinary medicine that would have summer availability is sought.  Potential for a UCARE project is encouraged but not required.

The spatial distribution of permeability in sand bars is key to the hydrologic function of river beds.  The goal of this project to develop an understanding of the sedimentary processes that control permeability heterogeneity.  The project will involve field and laboratory work.  Field work will be conducted in central Nebraska in the Loup River system.  This work will involve wading through shallow water, installing tubes for permeability testing, making measurements, and operating

This project will be testing a hypothesis that streambed conductivity will vary between the same and multiple stream orders as a function of soil type of the contributing watershed.  The student will have the opportunity to perform both field and lab work. In the field, the student will help measure streambed conductivity and collect streambed samples at multiple streams within the Frenchman Creek watershed. In the lab, the student will conduct sieve analysis for multiple samples to determine the grain-size distribution, which will then be used to estimate streambed conductivity.

This project aims to identify the ability of mixed severity fire regimes to promote species diversity. Specifically, students will be looking for differences in insect community composition that result from varying fire severities in the Pine Ridge region of Nebraska by identifying ground dwelling insects collected during the summer of 2016.
