Meeting Abstract 50.2 Tuesday, Jan. 5 The head-down posture of seahorses: an adaptation for pivot feeding? VAN WASSENBERGH, S.*; ROOS, G.; AERTS, P.; Univ. Antwerpen, Antwerpen; Univ. Antwerpen, Antwerpen; Univ. Antwerpen, Antwerpen sam.vanwassenbergh@ua.ac.be Syngnathid fishes capture prey by rotating their head quickly towards prey, and subsequently sucking it into their snout. Previous studies showed that head pivoting […]

The genetic basis of modularity in the African cichlid mandible
Meeting Abstract 50.1 Tuesday, Jan. 5 The genetic basis of modularity in the African cichlid mandible PARSONS, KJ*; MARQUEZ, E; COOPER, WJ; ALBERTSON, RC; Syracuse University; Florida State University; Syracuse University; Syracuse University kevpar66@gmail.com Most organisms are comprised of anatomical units recognizable from their developmental origins, or function. An emerging area of interest to biologists involves understanding […]

Fluid Dynamic Drag, Body Shape, and Endurance Swimming Performance among Coral Reef Fishes
Meeting Abstract 50.4 Tuesday, Jan. 5 Fluid Dynamic Drag, Body Shape, and Endurance Swimming Performance among Coral Reef Fishes WALKER, J.A.*; ALFARO, M.E.; FULTON, C.J.; Univ. Southern Maine; Univ. California, Los Angeles; Aust. Nat. Univ. walker@maine.edu The repeated evolution of streamlined body shapes among large, fast aquatic animals is a textbook example of evolutionary convergence. The oft-cited […]
Comparative Evolutionary Dynamics in Cichlid Adaptive Radiations Linking Lower Jaw Genetics, Morphology, and Mechanics
Meeting Abstract 50.3 Tuesday, Jan. 5 Comparative Evolutionary Dynamics in Cichlid Adaptive Radiations: Linking Lower Jaw Genetics, Morphology, and Mechanics HULSEY, CD*; STREELMAN, JT; Univ. of Tennessee; Georgia Institute of Technology chulsey@utk.edu The lower jaw is a major determinant of feeding diversification in cichlid adaptive radiations. It also provides an ideal phenotype to compare rates and patterns […]
The Effects of Serotonin on Leech Muscle Mechanics
Meeting Abstract 50.5 Thursday, Jan. 6 The Effects of Serotonin on Leech Muscle Mechanics GERRY, S.P.*; ELLERBY, D.J.; Wellesley College; Wellesley College sgerry@wellesley.edu The longitudinal body wall muscle of leeches (Hirudo verbana) supplies mechanical power during three distinct behaviors: swimming, crawling and suction feeding of blood. We quantified longitudinal muscle strain during these behaviors in vivo using […]
Forelimb muscle architecture of the American badger (Taxidea taxus) and groundhog (Marmota monax)
Meeting Abstract 50.6 Thursday, Jan. 6 Forelimb muscle architecture of the American badger (Taxidea taxus) and groundhog (Marmota monax). MOORE, A.L.*; BUTCHER, M.T.; Youngstown State Univ. almoore@student.ysu.edu The arrangement and orientation of muscle fibers reflect functional specializations of muscle. Relating muscle architecture with function is fundamental to understanding the roles of limb muscles. Limb muscles are often […]

Diversification of triggerfish (Teleostei Balistidae) cranial shape and jaw biomechanics
Meeting Abstract 50.2 Thursday, Jan. 6 Diversification of triggerfish (Teleostei: Balistidae) cranial shape and jaw biomechanics MCCORD, Charlene *; WESTNEAT, Mark ; University of Chicago; Field Museum of Natural History cmccord@uchicago.edu The subdivided adductor mandibulae muscles of triggerfishes provide an excellent experimental model upon which to analyze the biomechanical consequences of differential oral jaw morphology. We surveyed […]
