Meeting Abstract 32.6 Wednesday, Jan. 5 Do convergent means of premaxillary protrusion produce similar flows during suction feeding? STAAB, KL*; HOLZMAN, R; HERNANDEZ, LP; WAINWRIGHT, PC; George Washington Univ; UC Davis; George Washington Univ; UC Davis kstaab@gwmail.gwu.edu A protrusible upper jaw has independently evolved at least twice within teleosts and has been implicated in the success of […]

Dimorphic feeding kinematics in an ancestral threespine stickleback population
Meeting Abstract 32.4 Wednesday, Jan. 5 Dimorphic feeding kinematics in an ancestral threespine stickleback population MCGEE, M.D.; Univ. of California, Davis mcgee@ucdavis.edu Fish feeding kinematics generally show little sexual dimorphism, but it exists in some species and may increase their potential for rapid adaptation and speciation. I examined the feeding kinematics of anadromous threespine stickleback, Gasterosteus aculeatus, […]
Soft dentin results in unique, naturally bendable teeth in scraping catfish
Meeting Abstract 32.4 Thursday, Jan. 5 Soft dentin results in unique, naturally bendable teeth in scraping catfish GEERINCKX, Tom*; HUYSSEUNE, Ann; BOONE, Matthieu; CLAEYS, Myriam; COUVREUR, Marjolein; DE KEGEL, Barbara; MAST, Peter; VAN HOOREBEKE, Luc; VERBEKEN, Kim; ADRIAENS, Dominique; Ghent University; Ghent University; Ghent University; Ghent University; Ghent University; Ghent University; Ghent University; Ghent University; Ghent University; […]
Pharyngeal jaw function in three cyprinid fishes
Meeting Abstract 32.3 Thursday, Jan. 5 Pharyngeal jaw function in three cyprinid fishes GIDMARK, NJ*; TARRANT, JC; BRAINERD, EL; Brown University njg@brown.edu Cyprinids process food with highly specialized pharyngeal jaws. These jaws bear blade-like teeth in herbivores, molariform teeth in molluscivores, and heterodont dentition in omnivores. We studied food processing in grass carp (Ctenopharyngodon idella; herbivore), black […]
On the jaws of lamniform sharks
Meeting Abstract 32.2 Thursday, Jan. 5 On the jaws of lamniform sharks DEAN, Mason*; HUBER, Dan; GOO, Brian; DANOS, Nicole; SHIMADA, Kenshu; SUMMERS, Adam; MPI; UT; UCI; UCI; DePaul; FHL/UW mason.dean@mpikg.mpg.de The 15 species of lamniform sharks vary widely in feeding niche, including piscivores, megacarnivores and filter feeders. The functional morphology of their feeding apparatus is difficult […]
Morays de-couple feeding and respiration via a parabranchial pouch
Meeting Abstract 32.1 Thursday, Jan. 5 Morays de-couple feeding and respiration via a parabranchial pouch MEHTA, Rita/S*; POLLARD, Rachel/E; Univ. of California, Santa Cruz; Univ. of California, Davis rsmehta1123@gmail.com Moray eels are the only reported example of a teleost where the behaviors of feeding and respiration are decoupled. Moreover, the evolution of a specialized prey capture and […]
Does feeding mode constrain diversification of the skull in elopomorph fishes
Meeting Abstract 32.5 Thursday, Jan. 5 Does feeding mode constrain diversification of the skull in elopomorph fishes? COLLAR, David*; MEHTA, Rita; REVELL, Liam; ALFARO, Michael; WAINWRIGHT, Peter; Univ. California, Santa Cruz; Univ. California, Santa Cruz; Univ. Massachusetts, Boston; Univ. California, Los Angeles; Univ. California, Davis dcollar@ucsc.edu Behavioral innovations dramatically alter the way morphological traits interact with the […]
Divergence in the functional morphology and feeding kinematics of threespine stickleback
Meeting Abstract 32.6 Thursday, Jan. 5 Divergence in the functional morphology and feeding kinematics of threespine stickleback MCGEE, M.D.*; WAINWRIGHT, P.C.; Univ. of California, Davis; Univ. of California, Davis mcgee.matthew@gmail.com Studies of adaptive radiation rarely examine divergence across functional systems. We examined functional morphological divergence between benthic and limnetic threespine stickleback from British Columbia. We measured eleven […]
The medium matters tongue-flicking mechanics in air and water in the water snake (Nerodia sipedon)
Meeting Abstract 32.4 Friday, Jan. 4 The medium matters: tongue-flicking mechanics in air and water in the water snake (Nerodia sipedon) RYERSON, WG*; SCHWENK, K; Univ. of Connecticut william.ryerson@uconn.edu Snakes use oscillatory tongue-flicking to sample the environment for odor molecules. In air, the oscillations set up two pairs of vortices and regions of high velocity air flow. […]
The 3D kinematics of the trunk and hindlimbs during take-off and landing in zebra finch (Taeniopygia guttata)
Meeting Abstract 32.2 Friday, Jan. 4 The 3D kinematics of the trunk and hindlimbs during take-off and landing in zebra finch (Taeniopygia guttata) PROVINI, P*; BIEWENER, A A; ABOURACHID, A; Muséum National d’Histoire Naturelle, Paris; Muséum National d’Histoire Naturelle, Paris; Department of Organismic and Evolutionary Biology, Concord Field Station, Harvard University, Cambridge provini@mnhn.fr Take-off and landing are […]
