Project Abstract/Summary:
Deliberate contamination of drinking water makes it imperative to have an efficient, sensitive, specific and rapid sensor that can detect both xenobiotics and microbial organisms that cause harm to individuals. A multi-disciplinary group at Oklahoma State University is involved in developing a dual sensor that can be used in this capacity. The project will address two critical areas that are important for further development of the dual sensor: (1) identifying stable proteins that can maintain their function under various environmental conditions, and (2) Determining the specificity of autofluorescence signatures from bacteria.

Project Abstract/Summary:
This project addresses the productivity maintained by planktonic nutrient regeneration (remineralization) in freshwater lakes. The objective of this research is to examine the role and magnitude of planktonic consumer-driven nutrient regeneration in mesotropic Lake Texoma using laboratory mesocosm experiments based on consumer-food encounter rate models. By quantifying grazing and nutrient remineralizations rates by both macro and micro zooplankton assemblages, the research can help lake managers design and implement management measures including food web manipulation and runoff regulation.

Project Abstract/Summary:
A region's water supply is critical to its quality of life and economic development. Current limitations in public water supply distribution and wastewater capacity, coupled with increasing sensitivity to environmental degradation, has resulted in an immediate need to publicly address water issues in this part of Oklahoma. The Institute for Issue Management (IIMADR) will link information to stakeholders in TUA's water project through convening and facilitating information exchanges and public education on topical issues.
