Functional correlates of tooth structure in bats
Meeting Abstract 33.3 Wednesday, Jan. 5 Functional correlates of tooth structure in bats SANTANA, S.E.*; DUMONT, E.R.; UMass Amherst / UCLA; UMass Amherst ssantana@bio.umass.edu The morphology and function of mammalian teeth are strongly linked to diet. Within mammals, phyllostomid bats are the most diverse group in terms of dietary ecology and thus represent a unique system in […]
Feeding mechanics in billfishes (Xiphiidae and Istiophoridae) inferring the use of the bill from its mechanical properties
Meeting Abstract 33.1 Wednesday, Jan. 5 Feeding mechanics in billfishes (Xiphiidae and Istiophoridae): inferring the use of the bill from its mechanical properties HABEGGER, Maria Laura*; MOTTA, Philip J; MULLINS, Gray; STOKES, Michael; WINTERS, Daniel; University of South Florida mhabegge@mail.usf.edu Billfish are perciform fishes characterized for the presence of an elongated rostrum or “bill” composed mostly of […]
Temperature insensitivity of prey-capture dynamics in Rana pipiens reveals an elastic recoil mechanism
Meeting Abstract 32.1 Wednesday, Jan. 5 Temperature insensitivity of prey-capture dynamics in Rana pipiens reveals an elastic recoil mechanism SANDUSKY, P.E.*; DEBAN, S.M.; University of South Florida, Tampa; University of South Florida, Tampa psandusky@mail.usf.edu In ectotherms, thermal independence in the kinematics and dynamics of a movement suggests that an underlying physical mechanism, such as elastic recoil, powers […]

Modulation in the Strike Kinematics of the Ant-lion Larvae, Myrmeleon crudelis
Meeting Abstract 32.2 Wednesday, Jan. 5 Modulation in the Strike Kinematics of the Ant-lion Larvae, Myrmeleon crudelis LAMBERT, E.P.*; MOTTA, P.J.; Univ. of South Florida; Univ. of South Florida eplamber@mail.usf.edu Ant-lions are pit-building larvae (Neuroptera: Myrmeleontidae), which possess relatively large mandibles used for catching and consuming prey. Few studies involving terrestrial arthropod larvae have investigated feeding kinematics […]
Empirical Standardization of Bite-force Performance
Meeting Abstract 32.5 Wednesday, Jan. 5 Empirical Standardization of Bite-force Performance LAPPIN, A.K.**; JONES, M.E.H.; California State Polytechnic Univ., Pomona; University College London aklappin@csupomona.edu Essential aspects of measuring animal performance are elicitation of maximum effort and standardization for behavioral variation among trials, so as to capture maximum voluntary performance. Bite force, second only to locomotion in terms […]
Do convergent means of premaxillary protrusion produce similar flows during suction feeding
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, […]
