The biological significance of fluctuating asymmetry and sexual selection: a reply to Palmer

Article Abstract:

A. Richard Palmer demonstrated the detection of selective reporting by investigating a particular meta-analysis, the one conducted by Moller and Thornhill on sexual selection and fluctuating asymmetry. Although Palmer's recommendation that graphic techniques be regularly employed in meta-analysis is commendable, it is concluded that his specific conclusions about sexual selection and fluctuating asymmetry merit further investigation.

Criticism and interpretation, Palmer, A. Richard

Detecting publication bias in meta-analyses: a case study of fluctuating asymmetry and sexual selection

Article Abstract:

A study was conducted to address critical questions for meta-analysis such as the extent to which selective reporting bias estimates of average effect size and artificially inflate estimates of effect size heterogeneity. Results indicate that despite questions on the validity of meta-analyses, it nonetheless provides numerous advantages over narrative summaries including the ability to analyze the impact of selective reporting.

Is there an immunological cost to carotenoid-based ornamental coloration?

Article Abstract:

Whether or not ornamental displays and immune systems compete for carotenoid pigments has yet to be determined. At present, findings suggest several inconsistencies with this hypothesis.
