Using a 3D geometric morphometrics approach, we shed light on the major changes during the ontogenetic development of Hippopotamus amphibius. The main shift in the shape variability of cranial elements in juveniles can probably be related to the interruption of suckling. A less stressed shift in the cranial variability can probably be related to the attainment of sexual maturity.

Empirical evidence often deviates from the exponential preferences predicted by the normative model. A hyperbolic discount function better mirrors individual behavior, explaining temporal inconsistency - whereby preferences vary over time by applying a higher discount in the present.

Methods: The intracardiac echocardiography (ICE) measurements were: maximum transverse and longitudinal atrial septal defect (ASD) diameters in the aortic valve and four-chamber planes; area of the ASD and its equivalent circle diameter.
