Evaluation of Fish and Macroinvertebrate Indices of Biotic Integrity in the Bioassessment of the Illinois River Basin

Evaluating performances of the fish and invertebrate Indices of Biotic Integrity (IBIs) for a region is important to maintain rigorous assessment of the environmental quality of streams, especially with increasing urbanization. Timing of the assessment is considered important, with the critical season (low flow, high temperature) preferred, but the primary season (spring– summer) may be as efficient. I assisted with the collection and analysis of fish and macroinvertebrates using methods developed by the United States Environmental Protection Agency’s (USEPA) Rapid Bioassessment Protocols (RBPs) and the Arkansas Department of Environmental Quality (ADEQ), along with obtaining habitat and chemical assessments during primary and critical periods during 2007-2009 at ten sites in the Illinois River Basin up and downstream of two wastewater treatment plants (WWTPs). My objectives were to (1) compare fish and macroinvertebrate IBIs for use in the Illinois River Basin; (2) investigate correlations with each IBI and its metrics to nutrient, habitat, and watershed variables; (3) compare the efficacy of the IBIs during both critical and primary seasons; and (4) determine how two WWTPs in the area affect downstream water quality into Oklahoma. The two IBIs were strongly correlated with each other (Rs of 0.59); however, macroinvertebrates outperformed the fish. More regionally specific fish metrics should allow for better performing fish IBIs, but adequate performance was found. Combining the seasons’ data allowed for a more comprehensive and statistically significant assessment; however, the primary season evaluated each site comparably to the combined data and generally outperformed the critical seasons. The combined and primary seasons’ macroinvertebrate IBIs revealed sites with lowered environmental quality below the WWTPs but with quick returns to reference conditions. My results indicate that it may be possible to test IBIs during only the primary seasons to get efficient water quality and site comparison assessments

I Know What You Did Last Summer: The Ballot Initiative and Voter Turnout

“Know Thy Neighbor,” a public interest group established in 2005, has grabbed headlines in recent years for making public (or threatening to make public) the names of hundreds of thousands of registered voters who signed petitions qualifying anti-gay rights measures for state general election ballots in Massachusetts, Florida, Arkansas, Oregon, and Washington. These names, together with the mailing addresses, birthdates, and dates of signature for each signer, have long been public information in most states, but never before have they been put into a format (i.e., searchable, online databases) making them easy to access and analyze. In this pilot project, I perform multivariate analysis on a random sample of 500 registered Arkansas voters to determine the relative role of petition signing (versus vote history and age) in spurring voter turnout. This unique dataset allows an analysis, at the level of the individual voter, of the effectiveness of a relatively new tactic in American politics: using ballot measures to stimulate turnout for up-ticket candidate races. In the current study, while there was a correlation between petition signing and voter turnout, at the level of multivariate analysis, petition signing did not appear to be associated with voter turnout. However, individuals who signed petitions tended to have strong voting histories and were more likely than non-signers to cast ballots in the 2008 general election. The results of this research add to the already robust literature analyzing voter turnout in US political elections
