Meeting Abstract 123.8  Tuesday, Jan. 7 15:00  Investigating the Homology of Feathers and Scales using High-throughput Genomics MUSSER, JM*; WAGNER, GP; PRUM, RO; Yale University; Yale University; Yale University jacob.musser@yale.edu Feathers are an early avian innovation that facilitated the evolution of flight, greater thermoregulation, and other facets of avian life. However, the molecular basis for the evolution […]

Meeting Abstract 123.3  Tuesday, Jan. 7 14:00  Hedgehog signaling mediates adaptive variation in a complex functional system in the cichlid skull HU, Y.*; ALBERTSON, R.C.; UMass-Amherst; UMass-Amherst yinan@cns.umass.edu Adaptive variation in the craniofacial skeleton is a key component of resource specialization and divergence in vertebrates, but the genetic mechanisms that underlie complex patterns of craniofacial variation are […]

Meeting Abstract 123.5  Tuesday, Jan. 7 14:30  Experimentally induced homeotic shifts in anterior axial patterning mimic events in the evolution of the tetrapod skull MADDIN, H.C.*; PIEKARSKI, N.; HANKEN, J.; Harvard Univ.; Harvard Univ.; Harvard Univ. hillary.maddin@gmail.com The occipital region of the skull incorporates the sclerotomal portions of several anterior somites. Among tetrapods, amniotes incorporate more somites […]

Meeting Abstract 123.7  Tuesday, Jan. 7 15:00  Comparative studies on the ontogeny of the primary palate and nasal cavities in birds and mammals ABRAMYAN, J*; CHENG, J; RICHMAN, JM; University of British Columbia; UBC; UBC abramyan@dentistry.ubc.ca A critical period in craniofacial ontogeny involves the proper development of the primary palate and nasal cavities. Nasal cavities initiate as […]

Meeting Abstract 123.4  Tuesday, Jan. 7 14:15  A novel transcriptional regulator, lbh, regulates adaptive craniofacial variation in East African cichlids via neural crest cell migration POWDER, KE*; COUSIN, H; JACOBS-MCDANIELS, NL; ALBERTSON, RC; UMass Amherst; UMass Amherst; Syracuse Univ; UMass Amherst kepowder@bio.umass.edu Diversification of craniofacial structures to exploit new feeding niches is a cornerstone of adaptive radiations. […]

Meeting Abstract 122.4  Tuesday, Jan. 7 14:15  The soft serve: What tennis players can tell us about optimal performance in vertebrates WILSON, R S*; BROWN, C; WHEATLEY, R; University of Qld; University of Qld; University of Qld r.wilson@uq.edu.au Intuitively, we expect animals to use their maximum locomotor capabilities during key survival, reproductive and foraging behaviours – yet […]

Meeting Abstract 122.5  Tuesday, Jan. 7 14:30  Phase driven models of unperturbed locomotion WILSHIN, S*; REVZEN, S; Royal Veterinary College; University of Michigan swilshin@rvc.ac.uk A major paradigm in contemporary biomechnics is the use of perturbation studies to probe animal movement. Such studies either implicitly or explicitly compare perturbed animal motions to some estimate of how an unperturbed […]

Meeting Abstract 122.1  Tuesday, Jan. 7 13:30  How do movement speed and terrain visibility influence neuromuscular control of bipedal locomotion? GORDON, J.C.*; RANKIN, J.W.; WILSON, A.M.; DALEY, M.A.; Royal Veterinary College, UK; Royal Veterinary College, UK; Royal Veterinary College, UK; Royal Veterinary College, UK jcgordon@rvc.ac.uk Bipedal locomotion requires dynamic stability accomplished via complex interactions of sensory information, […]

Meeting Abstract 122.2  Tuesday, Jan. 7 13:45  Ground-bird running in non-rigid terrain: deducing task-level priorities in locomotion HUBICKI, C*; SPROEWITZ, A; HURST, J; DALEY, M; Oregon State University; Royal Veterinary College; Oregon State University; Royal Veterinary College hubickic@onid.orst.edu Terrestrial animals including ground birds regularly traverse terrain of irregular geometry and rigidity. We postulate that these diverse behaviors […]
