Meeting Abstract S3-7  Saturday, Jan. 4 11:30 – 12:00  Developmental basis of tooth regeneration TUCKER, A. S.; King’s College London abigail.tucker@kcl.ac.uk https://www.kcl.ac.uk/people/abigail-tucker During evolution of mammals there has been a move towards a reduction in the number of times teeth are replaced over an animal’s life-time. Most mammals have two sets of teeth (diphyodont), while most reptiles […]

Meeting Abstract S3-2  Saturday, Jan. 4 08:30 – 09:00  Developmental Genetic Analysis of Tooth Number Variation in Sticklebacks MILLER, CT; University of California, Berkeley ctmiller@berkeley.edu http://mcb.berkeley.edu/labs/miller/ Patterning of the dentition varies widely across different vertebrates, typically reflecting adaptations to diet. To begin to understand the developmental and genetic basis of evolved differences in dental patterning, we have […]

Meeting Abstract S3-11  Saturday, Jan. 4 15:00 – 15:30  Dental EvoDevOmics: Novel and conserved gene expression in shark tooth development FRASER, GJ*; THIERY , A; MARTIN, KJ; JAMES, K; COOPER, RL; HOWITT, C; JOHANSON, Z; University of Florida, Gainesville; King’s College, London; University of Sheffield; Natural History Museum, London; University of Sheffield; University of Sheffield; Natural History […]

Meeting Abstract S3-5  Saturday, Jan. 4 10:30 – 11:00  Crushing and puncturing: biomechanics of tooth shape CROFTS, SB*; SMITH, SM; ANDERSON, PLS; CROFTS, Stephanie; UIUC; Field Museum of Natural History; UIUC; 1984; 1984; 1984 scrofts@illinois.edu The tight relationship between tooth morphology and food material properties is often used to make inferences about an organism’s ecology and diet. […]

WAINWRIGHT, P.C.: The role of motor patterns in the evolution of fish feeding performance. How are fish feeding mechanisms modified during evolution to produce diversity in feeding ability and feeding ecology? In particular, are feeding motor patterns always altered in conjunction with biomechanical changes of muscle-skeleton linkages? Studies of the evolution of fish feeding mechanisms […]

DEBAN, S.M.*; O’REILLY, J.C.; NISHIKAWA, K.C.: The evolution of the motor control of feeding in amphibians. We compared prey capture among salamanders, frogs and caecilians in a phylogenetic context to identify major evolutionary transitions of the motor control of amphibian feeding. The common ancestor of living amphibians was most likely a predator with a free-living […]

KLEY, N.J.: The evolution of prey transport mechanisms in snakes Three fundamental modes of intraoral prey transport are recognized within Squamata. Lizards use either hyolingual or inertial transport mechanisms, both of which involve bilaterally symmetrical jaw movements. In contrast, most snakes exhibit a unilateral jaw-ratcheting mechanism that is characterized by asymmetrical jaw movements. Given the […]

HERREL, A.*; MEYERS, J.J.; NISHIKAWA, K.C.; DE VREE, F.: The evolution of feeding motor patterns in lizards: modulatory complexity and constraints. Previous research indicated that the evolution of feeding motor patterns across major taxonomic groups might have occurred without large modifications of the control of the jaw and hyolingual muscles. However, the proposal of this […]

Grubich, J.R.: Prey Capture in Actinopterygian Fishes: A review of suction feeding motor patterns with new evidence from an Elopomorph fish: Megalops atlanticus Suction feeding has long been recognized as the dominant mode of prey capture among ray-finned fishes. Elshoud-Oldenhave and Osse (1976) first proposed a triphasic sequence of the suction feeding strike: 1) a […]

Fetcho, J.R.: New approaches to the function of neuronal circuits that might simplify (a little) studies of the evolution of behavior. Understanding motor patterns (electromyograms) and their evolution requires understanding the neuronal circuits that produce them and the evolutionary changes in those circuits. This is not easy, which is perhaps why there are not many […]
