Fluctuating assymetry and the mating system of the Japanese scorpionfly, Panorpa japonica

Article Abstract:

The results of a field study of the mating system of the Japanese scorpionfly, Panorpa japonica, revealed that fluctuating asymmetry of male forewing length seemed to play a vital role in the male mating system under natural conditions.Mating males have low fluctuating asymmetry in contrast with non-mating males. Under semi-natural cage conditions, fluctuating asymmetry and male mating success and survival are negatively associated. The same relationship was evident among caged females for survival but not for mating success.

Effects of experimental manipulation of male secondary sex characters on female mate preference in red jungle fowl

Article Abstract:

Comb size, comb color and tail feather length in male red jungle fowl are manipulated, and female responses to these altered states are examined. Results show that hens largely ignore the trait that was altered, and shift to other characters as a basis for mate choice. Rather than using only one or two traits as criteria of mate choice, hens, therefore rely on a group of characters or behavioral displays, with each providing part of the information needed to make mate choice decisions.

Direct and indirect tests for publication bias: Asymmetry and sexual selection

Article Abstract:

An additional direct test of publication bias is performed using studies of the relationship between asymmetry and sexual selection. There is a small to intermediate effect size weighted by sample size of the relationship between asymmetry and sexual selection and this effect appears to be largely independent of publication bias as revealed by direct and indirect estimates of publication bias.
