Hadean zircons, found in the Jack Hills, Western Australia, are the oldest known materials on Earth, dating back to nearly 4.4 Ga or only ~150 Ma after formation. These tiny grains have been essential in transforming our view of the Hadean from a hot, hellish environment to one that appears much more hospitable to life with continental crust, water, and possibly even plate tectonics. Understanding the magmatic environment that leads to the formation of these ancient grains is fundamental to interpreting the geochemical signatures within them. Hypothesis of formation environments have ranged from plate boundary interactions to impact melt sheets. One important characteristic of the Jack Hills zircons is their unique inclusion assemblage,...

This project aims to understand how habitat (pond) age influences fish community structure and involves sampling ponds and streams in the Oakmulgee District, Talladega National Forest. The position is primarily field-based, where students will spend approximately eight hours per week conducting focused field research with graduate students and faculty in the Talladega National Forest. Off-campus transportation is provided. Students with interests in ecology and/or conservation biology, and a love of the outdoors, are particularly encouraged to apply....

IHNV is a virus that affects Pacific salmon. It is especially of concern in hatcheries where juvenile fish are raised for release in the Columbia River basin. There can be up to 90% mortality of a juvenile hatchery cohort. We are trying to identify the predominant pathways by which IHNV is spread to juvenile salmon in hatcheries. We have IHNV testing records from hundreds of sites in the Columbia River basin and have GIS layers of site locations and river systems. The project is to calculate the river distance between hatchery sites. For example, if sites A, B, and C could have exposed site D to IHNV, how far would water or a fish have to travel between sites A and D, sites B and D, or sites C and D?...

Geographical Information System Analysis and access to healthcare services: A scoping literature review
UNDERGRADUATE research assistants (2) needed to conduct a scoping literature review of geographic information systems (GIS) use in the areas of diabetes, healthcare service access, health outcomes, and health disparities. The scoping review will identify limited and specific studies about how GIS has been used to investigate access and/or distance to healthcare services for diabetes. Literature searches of electronic databases will be completed using the following search terms (and derivatives): “geographic information systems” AND “diabetes”. The Methodology for Joanna Briggs Scoping Reviews will be used utilized. ...
