Developmental stability, the ability of an individual to eliminate environmental sequal eclipse 5 battery disturbances while expressing a heritable phenotypic trait, was compared in two walnut (Juglans regia L.) populations, a natural and an artificial.Bilateral leaf morphometrics were used to estimate fluctuating asymmetry which refers to random deviation from perfect symmetry of bilateral traits resulting from extrinsic and intrinsic perturbations not buffered during development.Fluctuating asymmetry was used as a proxy of developmental stability.

We analyzed our data from a Bayesian perspective showing that developmental stability levels are decreased in the natural population.Our results indicate that an attention may be directed towards the conservation of the natural walnut resources of the area.Fluctuating asymmetry as an indicator of developmental stability may here contribute especially in the framework of comparative studies as a population biomonitoring tool.
