Meeting Abstract 112.4  Saturday, Jan. 7  Correlation of bone loading and muscle function in the hindlimb of the river cooter turtle (Pseudemys concinna) AIELLO, B.R.*; BLOB, R.W.; BUTCHER, M.T.; Youngstown State University; Clemson University; Youngstown State University brettronaldaiello@gmail.com Limb muscles have important roles during locomotion, such as counteracting ground reaction forces (GRF) and generating propulsive mechanical work […]

Meeting Abstract 112.3  Saturday, Jan. 7  Analysis of rat hindlimb muscle and tendon mechanics using x-ray videoradiography HORNER, Angela M*; ASTLEY, Henry C; ROBERTS, Thomas J; Brown University; Brown University; Brown University angela_horner@brown.edu Biomechanical scaling principles have shaped our understanding of mammal locomotion for decades, but our understanding of tissue level function is biased toward taxa 1 […]

Meeting Abstract 112.2  Monday, Jan. 7  Quantifying inter-specific variations through the automated discovery of stereotyped behaviors BERMAN, G.J.*; CHOI, D.; BIALEK, W.; SHAEVITZ, J.W.; Princeton University; Princeton University; Princeton University; Princeton University gberman@princeton.edu In recent years, the scientific community has learned a great deal about morphological evolution through making comparisons between closely-related species, discovering, for instance, that […]

Meeting Abstract 112.1  Monday, Jan. 7  Optimal Performance Theory: developing a framework for understanding whole-animal performance in the wild WILSON, R S*; CARTER, A J; The University of Queensland; University of Cambridge r.wilson@uq.edu.au Should an animal run as fast as it can when trying to escape a predator? What about when running to catch food or whilst […]

Meeting Abstract 112.3  Monday, Jan. 7  Many-to-many mapping of phenotype on function, and the F-array BERGMANN, P.J.*; MCELROY, E.J.; Clark University; College of Charleston pbergmann@clarku.edu Relationships between phenotype and function are often complex, involving trade-offs, facilitations, redundancies, and traits that influence only one aspect of function. In systems with multiple phenotypic parts and multiple functional capacities, phenotype-function […]

Meeting Abstract 112.5  Monday, Jan. 7  Assembly and disassembly of fire ant bivouacs MLOT, N.J.*; MORRISON, J.; LEAMY, M.; TOVEY, C.A.; HU, D.L.; Georgia Tech, Atlanta; Georgia Tech, Atlanta; Georgia Tech, Atlanta; Georgia Tech, Atlanta; Georgia Tech, Atlanta njmlot@gmail.com Fire ants are capable of linking together to form bivouacs, which serve as temporary shelter when alternatives cannot […]

Meeting Abstract 112.5  Tuesday, Jan. 7 11:15  Torque production and stability during narrow branch locomotion CHADWELL, BA*; YOUNG, JW; NEOMED; NEOMED jwyoung@neomed.edu During locomotion on narrow branches, lateral movement induces increases in the angular momentum of the center of mass (COM) that, if unchecked, will topple the animal from the branch. Grasping appendages may facilitate balance on […]
