What is Developmental Stability Morphometrics?
Developmental Stability Morphometrics quantifies fluctuating asymmetry and canalization in form using geometric morphometric measures of developmental instability.
This approach analyzes Procrustes shape coordinates to separate individual variation from directional and fluctuating asymmetry (Klingenberg et al., 2002, 1001 citations). It links instability metrics to genetic, environmental, and stress factors in organisms (Hallgrímsson et al., 2002, 389 citations). Over 10 key papers from 2001-2016 span 300-1280 citations.
Why It Matters
Metrics from developmental stability morphometrics act as biomarkers for organismal fitness and environmental stress in wild populations (Hallgrímsson et al., 2002). They reveal how perturbations affect canalization and integration in primate limbs and symmetric structures (Klingenberg et al., 2002; Klingenberg, 2016, 973 citations). Applications include taxonomy via leaf shape analysis (Viscosi and Cardini, 2011, 406 citations) and evolutionary trajectories (True and Haag, 2001, 690 citations).
Key Research Challenges
Quantifying Fluctuating Asymmetry
Separating fluctuating asymmetry from directional asymmetry and measurement error requires object symmetry methods for symmetric structures like skulls (Klingenberg et al., 2002). Procrustes superimposition must account for size, position, and orientation (Mitteroecker and Gunz, 2009). Individual variation quantification remains sensitive to landmark placement.
Linking Instability to Stress
Correlating morphometric instability with genetic and environmental stressors demands robust statistical models amid canalization effects (Hallgrímsson et al., 2002). Perturbations in wild populations complicate causation inference (True and Haag, 2001). Multi-level integration analysis across phylogeny adds complexity (Klingenberg, 2014, 347 citations).
Allometry and Integration Effects
Allometric scaling confounds shape instability measures, requiring separation of size, shape, and form (Klingenberg, 2016). Morphological integration varies across levels, from individuals to deep time (Goswami et al., 2014, 351 citations). Covariance matrices on phylogenies demand evolutionary models (Adams and Felice, 2014, 202 citations).
