Sacral Morphology Of Prehensile-Tailed Primates In Relation To Biomechanical Loading, Hannah Grace Showalter
Sacral Morphology Of Prehensile-Tailed Primates In Relation To Biomechanical Loading, Hannah Grace Showalter
Graduate Theses and Dissertations
The few available comparative studies of prehensile tail anatomy in primates have established that several features of the caudal vertebrae are associated with adaptation to the increased loading of the tail during prehension. Given that the caudal vertebrae are anchored to the sacrum, it stands to reason that sacral morphology should also covary with tail prehensility. Convergent evolution of prehension in ateline and cebine primates and clear variation in the use of tails among taxa raises questions not only of how sacral morphology differs between prehensile and non-prehensile taxa, but whether different prehensile-tailed taxa evolved the same solutions to the …
3-D Morphometric Analysis Of The Primate Elbow Joint, Seth Brockman Boren
3-D Morphometric Analysis Of The Primate Elbow Joint, Seth Brockman Boren
Graduate Theses and Dissertations
Large body size requires limb joints capable of supporting said weight, and a species exhibiting sexual size dimorphism may necessitate joint size differences between the sexes of the species. If habitual behavior differs with body size, one may expect to see significant variation in joint morphology between species and the sexes within species. The following analysis tests two hypotheses: (1) that significant differences in joint size between males and females correlate with the magnitude of sexual dimorphism and (2) that there is significant interspecific variance in joint shape between males and females of the same species. The first hypothesis is …
