ASSESSING 3D PHOTOGRAMMETRY TECHNIQUES IN CRANIOMETRICS
Morphometrics (the measurement of morphological features) has been revolutionized by the creation of new techniques to study how organismal shape co-varies with several factors such as ecophenotypy. Ecophenotypy refers to the divergence of phenotypes due to developmental changes induced by local env...
