Fluctuating asymmetry is the random deviation from perfect symmetry in populations of organisms. It is a measure of developmental noise, which reflects a population’s average state of adaptation and coadaptation. Moreover, it often increases under both environmental and genetic stress. Researchers study fluctuating asymmetry as deviations from bilateral, radial, rotational, dihedral, translational, helical, and fractal symmetries. Fluctuating asymmetry is measured via traditional measures of dispersion (variances and mean absolute deviations), landmark methods for shape asymmetry, and continuous symmetry measures. It has numerous applications in evolutionary biology, quantitative genetics, environmental biology, ecotoxicology, conservation biology, anthropology, agriculture and aquaculture, evolutionary psychology, and medicine and public health.
The aim of this Special Issue is to highlight all aspects of fluctuating asymmetry in the biological sciences. Research papers, comprehensive reviews, and discussions of theory are especially welcome. However, any other kind of paper: communication, technical note, short overview or comment will also be taken into consideration.

Title: Effects of Variation in Measurement Error in the Assessment of (Fluctuating) Asymmetry: a Bayesian Model and Its Application to Simulated and Empirical Data

Abstract: As the magnitude of fluctuating asymmetry (FA) is usually small relative to trait size, assessing the amount of measurement error (ME) is an important aspect in asymmetry studies. While the statistical methodology to assess and correct for ME has been developed decades ago, it is always assumed that ME does not vary across individuals. In this paper we develop a statistical model to explicitly incorporate this variation in ME in a Bayesian framework. The performance of the model is explored using simulated datasets. The model is then applied to a number of empirical datasets to assess the amount of variation in ME in real data.
