DICAROS: Diffeomorphic Ancestral Shape Reconstruction on Phylogenies

DICAROS improves ancestral shape reconstruction by modeling shape correlations using diffeomorphic dynamics, outperforming traditional methods on non-symmetric trees.

Morphological integration of the avian beak facilitates evolution along lines of least resistance

The paper evaluates macroevolutionary patterns in avian beak morphology using 3D landmarks and a supertree, finding that integration promotes phenotypic evolution by reducing developmental constraints.

Diffeomorphic Independent Contrasts for Ancestral Reconstruction of Shapes

This paper introduces DICAROS, a method for ancestral shape reconstruction that outperforms existing methods by combining LDDMM and Felsensteins Independent Contrasts, and applies it to swallowtail butterflies.

3D shell asymmetry of Testudines as a potential biomarker for environmental stress

This study analyzes shell asymmetry in turtles using 3D scans to show ecological influences on shell shape and asymmetry, suggesting FA as a biomarker for environmental stress.

Neural crest cell biology shapes lizard skull evolution across evolutionary time scales

The paper examines how neural crest cell biology influences skull evolution in lizards, finding that neural crest-derived bones evolve rapidly under sexual selection but show slower rates and less disparity across species.
