Meeting Abstract 51.11 Saturday, Jan. 5 Morphometrics of Crocodilian Cranial Variation in Ecomorphology and Ontogeny SADLEIR, R.W.; Univ. of Chicago and the Field Museum, Chicago, IL rsadleir@uchicago.edu Crown group crocodilians exhibit a high degree of cranial shape variation and convergence throughout their 80 million-year fossil record. Phylogenetic character correlation tests show that repeated transitions among generalized, blunt […]

Evolutionary and developmental origins of the maxillary dentition of snakes Insights from tooth surface morphology
Meeting Abstract 51.6 Saturday, Jan. 5 Evolutionary and developmental origins of the maxillary dentition of snakes: Insights from tooth surface morphology JACKSON, K.*; VONK, , F.J.; ADMIRAAL, J.; RICHARDSON, M.K.; Whitman College; Leiden University; Leiden University; Leiden University jacksok@whitman.edu The Colubroidea is an enormous group of snakes (approx. 2400 species) made up of many lineages, whose branching […]
Evolution of the Frontal Sinuses in Bovidae
Meeting Abstract 51.3 Saturday, Jan. 5 Evolution of the Frontal Sinuses in Bovidae FARKE, A.A.; Stony Brook Univ., New York afarke@ic.sunysb.edu Cranial pneumaticity is remarkably homoplastic, with independent pneumatization of some cranial bones occurring multiple times across mammals. The factors that drive pneumatization are unclear, however. Bovids, a clade of horned artiodactyls including sheep, goats, and cattle, […]
Early development of Ancistrus cf triradiatus and Corydoras aeneus a case study for understanding the role of ontogenetic patterning in loricarioid evolution
Meeting Abstract 51.8 Saturday, Jan. 5 Early development of Ancistrus cf. triradiatus and Corydoras aeneus: a case study for understanding the role of ontogenetic patterning in loricarioid evolution. HUYSENTRUYT, F.*; GEERINCKX, T.; ADRIAENS, D.; Ghent University, Gent, Belgium frank.huysentruyt@ugent.be The Neotropical fauna is one of the most diverse and least known; understanding this diversity and the specific […]
Convergence in a Mechanically Complex Phenotype Detecting Structural Adaptations For Crushing in Cichlid Fishes
Meeting Abstract 51.7 Saturday, Jan. 5 Convergence in a Mechanically Complex Phenotype: Detecting Structural Adaptations For Crushing in Cichlid Fishes HULSEY, CD*; ROBERTS, RJ; STREELMAN, JT; Univ. of Tennessee; Georgia Tech; Georgia Tech dh251@mail.gatech.edu Morphological convergence provides strong evidence that evolution is adaptive. However, putatively convergent morphology is often examined in two-dimensions with no explicit model of […]
Conservatism in lizard vertebral number evolution is widespread but not universal
Meeting Abstract 51.4 Saturday, Jan. 5 Conservatism in lizard vertebral number evolution is widespread but not universal. BERGMANN, P.J.*; IRSCHICK, D.J.; University of Massachusetts Amherst; University of Massachusetts Amherst pjbergma@nsm.umass.edu We collected vertebral number data for a sample of 2402 lizards, representing 1045 species, or 27% of extant diversity. We mapped these data onto a supertree of […]
Comparative morphology of glandular setae, distal claws, and terminal fangs of the crustacean remipede Speleonectes tanumekes
Meeting Abstract 51.1 Saturday, Jan. 5 Comparative morphology of glandular setae, distal claws, and terminal fangs of the crustacean remipede Speleonectes tanumekes. VAN DER HAM, J.L.*; FELGENHAUER, B.E.; Univ. Louisiana at Lafayette; Univ. Louisiana at Lafayette jvdham@louisiana.edu Terminal pores on crustacean setae are commonly associated with chemoreception. We present an exception to that association with the description […]
Tuned to the right signal Suction feeding interactions with bow wave increase detection distance of fish by aquatic prey
Meeting Abstract 51.5 Monday, Jan. 5 Tuned to the right signal: Suction feeding interactions with bow wave increase detection distance of fish by aquatic prey HOLZMAN, Roi*; WAINWRIGHT, Peter; Univ. of California, Davis; Univ. of California, Davis raholzman@ucdavis.edu Predation on zooplankton by fish is a major trophic pathway in aquatic communities, and this predator-prey interaction represents a […]
Simultaneous correlation of odor-plume structure and behavior I Three-dimensional plume structure at antennules affects speed and sensor height in tracking blue crabs
Meeting Abstract 51.1 Monday, Jan. 5 Simultaneous correlation of odor-plume structure and behavior: I. Three-dimensional plume structure at antennules affects speed and sensor height in tracking blue crabs PAGE, J.L.*; DICKMAN, B.D.; WEBSTER, D.R.; WEISSBURG, M.J.; Georgia Institute of Technology, Atlanta; Georgia Institute of Technology, Atlanta; Georgia Institute of Technology, Atlanta; Georgia Institute of Technology, Atlanta jennifer.page82@gmail.com […]
Performance Differences in Stingrays with Varying Electrosensory System Morphology
Meeting Abstract 51.6 Monday, Jan. 5 Performance Differences in Stingrays with Varying Electrosensory System Morphology JORDAN, LK*; KAJIURA, SM; GORDON, MS; Univ. of California, Los Angeles; Florida Atlantic University; Univ. of California, Los Angeles ljordan@ucla.edu Electrosensory signals are important during the final stages of prey capture in elasmobranch fishes (sharks, skates, and rays), and may be particularly […]
