Meeting Abstract 18.5  Jan. 5  It�s all in the timing: forces exerted on prey during suction feeding in Bluegill HOLZMAN, R*; DAY, SW; HIGHAM, TE; WAINWRIGHT, PC; Univ. of California, Davis; Rochester Institute of Technology; Univ. of California, Davis; Univ. of California, Davis raholzman@ucdavis.edu Suction feeding is perhaps the most common prey capture strategy of fishes. During […]

Meeting Abstract 18.1  Jan. 5  Hyoid mechanics and muscle function during feeding in white-spotted bamboo sharks, Chiloscyllium plagiosum. RAMSAY, J.B.*; WILGA, C.D.; Univ. of Rhode Island; Univ. of Rhode Island jasonramsay@mail.uri.edu The feeding apparatus in white-spotted bamboo sharks, Chiloscyllium plagiosum exhibits many characters associated with suction feeding such as labial cartilages to occlude the lateral portions of […]

Meeting Abstract 18.3  Jan. 5  Eating big: Innovation in the moray eel feeding mechanism MEHTA, R.S*; WAINWRIGHT, P.C.; Univ. of California, Davis; Univ. of California,Davis rsmehta@ucdavis.edu Suction feeding is ubiquitous among aquatic vertebrates. We report the discovery that a major radiation of teleost fishes, the moray eels of the anguilliform family Muraenidae, do not use suction to […]

Meeting Abstract 18.4  Jan. 5  Does biting performance trades off with suction feeding performance in clariid catfish? VAN WASSENBERGH, S.*; HERREL, A.; ADRIAENS, D.; AERTS, P.; Universiteit Antwerpen; Universiteit Antwerpen; Ghent University; Universiteit Antwerpen sam.vanwassenbergh@ua.ac.be It is generally assumed that biting performance trades off with suction feeding performance in fish because both feeding types may place conflicting […]

Meeting Abstract 18.2  Jan. 5  Congruent patterns of muscle activity and kinematics in modulation of a novel feeding mechanism in fishes KONOW, N*; SANFORD, CPJ; Hofstra University; Hofstra University nicolai.konow@hofstra.edu Concurrent analyses of motor activity patterns and kinematics in a functional system, although rarely tested, can convey a detailed understanding of how changes in muscle activity can […]

Meeting Abstract 18.6  Jan. 5  Cichlid Pectoral Fins: Is there a Link Between Locomotion and Feeding? HULSEY, CD*; ROBERTS, R; STREELMAN, JT; Georgia Tech; Georgia Tech; Georgia Tech dh251@mail.gatech.edu Although the unparalleled feeding diversity of cichlid fishes in the African Great Lakes is widely recognized, the locomotory diversity of these rapidly radiating groups remains underappreciated. We quantified […]

Meeting Abstract 17.4  Jan. 4  Why are our toes so tiny? Walking, running and the evolution of a short forefoot in the genus Homo ROLIAN, Campbell*; LIEBERMAN, Daniel E.; SCOTT, John W.; Harvard University; Harvard University; Vanderbilt University rolian@fas.harvard.edu Humans have an extremely short forefoot relative to total foot length. The derived pedal proportions of humans are […]

Meeting Abstract 17.1  Jan. 4  The energetics of quadrupedal and bipedal locomotion in chimpanzees RAICHLEN, D.A.*; PONTZER, H.; SOCKOL, M.D.; University of Arizona; Washington University; University of California, Davis raichlen@email.arizona.edu For decades, researchers have worked to discover general principles governing the energetic costs of terrestrial locomotion. The Force Production Hypothesis satisfies many of the requirements of a […]

Meeting Abstract 17.6  Jan. 4  Small-bodied primates adapt asymmetrical gait dynamics to locomotion on arboreal substrates YOUNG, JW; Stony Brook University jwyoung@ic.sunysb.edu Whereas the dynamics of symmetrical gaits (i.e., walking and running) in primates have been well researched, their use of asymmetrical gaits (i.e., galloping and bounding) remains understudied. Asymmetrical gaits are usually associated with greater peak […]

Meeting Abstract 17.3  Jan. 4  Humans use a unique mechanism to stabilize the head during running LIEBERMAN, DE*; BRAMBLE, DM; RAICHLEN, DA; Harvard University; University of Utah; Uinversity of Arizona danlieb@fas.harvard.edu Mammals must stabilize the head during running to keep angular accelerations of head within the operating range of the vestibulo-ocular (VOR) reflexes. However, several unique aspects […]
