DOI: 10.1002/etc.3688
Abstract: Variation in avian bilateral symmetry can be an indicator of developmental instability in response to a variety of stressors, including environmental contaminants. The authors used composite measures of fluctuating asymmetry to examine the influence of… read more here.

Fluctuating asymmetry of adult Chinook Salmon (Oncorhynchus tshawytscha) otoliths from wild and hatchery origins

DOI: 10.1007/s10452-019-09733-0
Abstract: Fluctuating asymmetry is the non-directional deviations from bilateral symmetry and occurs across organisms. Fish otoliths are often used to test for differences in symmetry as otoliths aid in hearing, homing, and balance. Here, we evaluated… read more here.

DOI: 10.1007/s10709-017-9966-x
Abstract: Metric (e.g., body size) and meristic (e.g., bristle number) traits are of general use in quantitative genetic studies, and the phenotypic variance is subdivided into a genetic and a non-genetic environmental component. The non-genetic variance… read more here.

DOI: 10.1016/j.earlhumdev.2018.10.007
Abstract: BACKGROUND Dermatoglyphics alterations have been demonstrated to be an effective complement in the diagnosis of developmental disorders and a marker of prenatal stress. Several genetic and environmental factors can modify their morphology. Once defined, dermatoglyphics… read more here.

DOI: 10.1016/j.ecolind.2016.11.004
Abstract: Abstract Increased morphological fluctuating asymmetry is considered as an indication that the extent of a natural stress has surpassed the ability of the genotype to maintain the normal symmetry in the body plan. Young leaves… read more here.
