Testing hypotheses for the function of the carnivoran baculum using finite-element analysis
The high degree of endemism on Sulawesi has previously been suggested to have vicariant origins, dating back to 40 Ma. Recent studies, however, suggest that much of Sulawesi's fauna assembled over the last 15 Myr. Here, we test the hypothesis that more recent uplift of previously submerged portions of land...Brassey, Charlotte A ; Gardiner, James G ; Kitchener, Andrew C

The role of cross-sectional geometry, curvature and limb posture in maintaining equal safety factors: A computed tomography study
The limb bones of an elephant are considered to experience similar peak locomotory stresses as a shrew. "Safety factors" are maintained across the entire range of body masses through a combination of robusticity of long bones, postural variation, and modification of gait. The relative contributions of these variables remain uncertain....Brassey, Charlotte A ; Kitchener, Andrew C ; Withers, P J ; Manning, Phillip L ; Sellers, William I

Finite element modelling versus classic beam theory: comparing methods for stress estimation in a morphologically diverse sample of vertebrate long bones
Classic beam theory is frequently used in biomechanics to model the stress behaviour of vertebrate long bones, particularly when creating intraspecific scaling models. Although methodologically straightforward, classic beam theory requires complex irregular bones to be approximated as slender beams, and the errors associated with simplifying complex organic structures to such...Brassey, Charlotte A ; Margetts, L ; Kitchener, Andrew C ; Withers, P J ; Manning, Phillip L …
