Meeting Abstract 90.1  Wednesday, Jan. 7  Ontogeny of locomotor performance in a ground bird JACKSON, B.E.*; DIAL, K.P.; Univ. of Montana; Univ. of Montana brandon.jackson@mso.umt.edu Due to post-natal predation pressure many juvenile animals face a developmental tradeoff between escape ability and investment in other systems. In birds these tradeoffs are unique because birds transition through hindlimb- to […]

Meeting Abstract 90.3  Wednesday, Jan. 7  Ontogenetic convergence in ventral skull shape between males and females of a sexually dimorphic antelope BRAKORA, Katherine*; KHUC, Kim; University of California, Berkeley kbrakora@berkeley.edu Although antelope provide many classic examples of sexual dimorphism among mammals, their morphology has not been systematically quantified in terms of sexual differences in size, shape or […]

Meeting Abstract 90.7  Wednesday, Jan. 7  ONTOGENETIC ALLOMETRY OF LONG BONES IN MAMMALS AND DINOSAURS AND ITS USE AS A PREDICTOR OF LIFE HISTORY TRAITS KILBOURNE, BM; University of Chicago bmkilbou@uchicago.edu In addition to providing insight into the ontogenetic development of the locomotor system, ontogenetic limb bone allometry may reflect other aspects of an organism’s life history, […]

Meeting Abstract 90.4  Wednesday, Jan. 7  Development of a functional complex: Ontogeny of the zebrafish pharyngeal jaw apparatus O’QUIN, C.T.*; HERNANDEZ, L.P.; The George Washington University; The George Washington University ctoquin@gwu.edu The pharyngeal jaw apparatus of teleosts has long been of interest to both functional and descriptive morphologists alike. However, little to no work has been done […]

Meeting Abstract 90.11  Thursday, Jan. 7  Tooth Root Surface Area as an Indicator of Bite Force SELF, CJ; University of Washington, Seattle cjself@u.washington.edu The tooth root provides attachment area for the periodontal ligament and an increase in root area may be advantageous for subsisting on harder food or having a larger bite force. The goal of this […]

Meeting Abstract 90.3  Thursday, Jan. 7  The Effect of Occlusion on Alveolar Bone Biomechanics in the Miniature Pig, Sus scrofa YEH, K.D.; POPOWICS, T.*; RAFFERTY, K.; HERRING, S.; University of Washington, Seattle popowics@u.washington.edu This study investigated the role of occlusion in the biomechanical properties of alveolar bone in the miniature pig, Sus scrofa. The hypothesis tested was […]
