Validation of Annulus Formation in Golden Shiner Otoliths

Abstract Golden Shiner Notemigonus crysoleucas is found in many lakes and ponds across the southeastern United States. Though it is a common species, otolith age validation methods have not been published. The objective of this study was to confirm annulus formation in lapillar otoliths of Golden Shiners collected monthly from September 2015 through August 2016 in Lake Jackson, Florida (Leon County). We collected at least 12 individuals each month of similar length (168–249 mm; presumably of the same cohort) to document annulus formation throughout the year. We sacrificed a total of 177 individuals from the 2013 year class, and we used their lapillar otoliths for marginal incremental analysis to calculate an index of completion and validate annulus formation. The monthly index of completion was highest from January through March and lowest in May and June, indicating that annuli were deposited once per year and confirming that lapillar otoliths are a valid age estimation structure for Golden Shiners.

Abstract Spotted suckers Minytrema melanops are found in many river systems from the Midwest to the Southeast United States. Though they are a relatively abundant species, otolith age validation methods have not been reported. The objective of this study was to validate annulus formation on the lapillar otolith for spotted suckers. We collected spotted suckers monthly from December 2005 to November 2006 in the Apalachicola River, Florida. Using marginal incremental analysis on whole browned lapillar otoliths, we validated that spotted suckers form one annulus per year between May and June. We also report population characteristics including a length–weight regression. This study validates otolith aging to provide an avenue for accurately assessing the age composition of spotted sucker populations, which will facilitate a better understanding of growth, recruitment, and mortality of the species.

Does Enhancing Mind Perception Affect Conspiracy Belief?

The Mind

This study was conducted to determine the effectiveness of a novel mind perception manipulation. Mind perception is currently theorized to be an essential aspect of a number of human social psychological processes. Thus, a successful manipulation would allow for the causal study of those processes. This manipulation was created in an attempt to explore the downstream impact of mind perception on the endorsement of conspiracy theories. Conspiracy theories are steadily becoming more and more prominent in social discourse. Endorsement of conspiracy theories are beginning to show real world ramifications such as a danger to human health (e.g., in the anti-vaccination movement). A sample of college students (valid N = 53) from a large rural institution in the southeastern United States participated for course credit. These participants completed a mind perception pretest, were randomly assigned to either the manipulation in question (in which participants are asked to consider the ‘mind’ of several targets and write their thoughts about them) or the control condition, and then they completed a posttest. The mixed ANOVA revealed that the interaction term between Time and Condition was not significant. Because the manipulation did not work, other analyses were aborted, in accord with the pre-registration. My Discussion focuses on the procedures and potential shortcomings of this manipulation, in an effort to lay the groundwork for a successful one.
