No relationship between vertebral column shifts and limb fluctuating asymmetry in human foetuses [PDF]
PeerJ, 2017 Disturbance from the normal developmental trajectory of a trait during growth—the so-called developmental instability—can be observed morphologically through phenodeviants and subtle deviations from perfect symmetry (fluctuating asymmetry).

Cranial-Vertebral-Maxillary Morphological Integration in Down Syndrome
Biology, 2022 Background: Morphological integration refers to the tendency of anatomical structures to show correlated variations because they develop in response to shared developmental processes or function in concert with other structures.

Symmetry-Breaking Stabilities in Carapace Curvature on Testudo (Reptilia, Testudinidae)
Animals, 2022 The aim of this research was to contribute to the study of the doming geometry of Testudo carapace as an unstable point of equilibrium when animals are overturned.

Nature Communications, 2022 Ectopic transcription factor expression can reprogram mouse fibroblasts to pluripotent or trophoblast stem cells. Here the authors apply multi-omics analyses to the induction of pluripotency and trophoblast stem cell state from fibroblasts, comparing ...

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2021 Directional asymmetry (the preferential expression of a character on one side rather than the other) and fluctuating asymmetry (minor, random and independent deviations from bilateral symmetry) are increasingly investigated in modern corpuses of deceased

Symmetry, 2020 Fluctuating asymmetry (FA), in contrast with other asymmetries, is the bilateral asymmetry that represents small, random developmental differences between right and left sides.

Cases of trunk segmental anomalies in the geophilomorph centipedes Clinopodes flavidus C.L. Koch and clinopodes trebevicensis (Verhoeff) (Chilopoda: Geophilomorpha) [PDF]
Archives of Biological Sciences, 2011 We describe and analyze two examples of naturally occurring morphological anomalies in the geophilomorph centipedes. Recorded abnormalities include a supernumerary hemisclerite in an adult female specimen of Clinopodes flavidus C.L.

Developmental instability in German Iris flower as a potential biomonitoring method [PDF]
Archives of Biological Sciences, 2016 In light of the increasing need for appropriate, cost-effective detection methods of anthropogenic pollution, we evaluated the biomonitoring potential of flower developmental instability (DI) on a widely planted decorative species, Iris ...

Fluctuating Asymmetry and Developmental Instability, a Guide to Best Practice
Symmetry, 2020 Best practices in studies of developmental instability, as measured by fluctuating asymmetry, have developed over the past 60 years. Unfortunately, they are haphazardly applied in many of the papers submitted for review.

Developmental Psychology, 2022 Existing research focused on social role destabilization (historical increases in role instability) and destandardization (historical increases in variability of role instability) has primarily focused on discrete social roles during discrete periods of ...
