Meeting Abstract 72.2  Tuesday, Jan. 6  Constructing a complex morphological novelty: Insights from growth, development, and genetics of the cypriniform Weberian apparatus BIRD, Nathan C.*; HERNANDEZ, L. Patricia; George Washington University; George Washington University nbird@gwmail.gwu.edu Vertebrate morphologists have long examined hearing capabilities in fishes, with particular emphasis on so-called hearing specialists. However, less emphasis has been placed […]

Meeting Abstract 72.6  Tuesday, Jan. 6  Candiru catfish … a fish with many names and many novelties ADRIAENS, D.*; CHRISTIAENS, J.; Ghent University, Gent Belgium; Ghent University, Gent Belgium dominique.adriaens@ugent.be Evolutionary novelties are considered as crucial step stones during adaptive evolution, triggering novel functions and allowing novel ecological landscapes to be explored. De novo formations and decouplings […]

Meeting Abstract 72.5  Thursday, Jan. 6  Visual stabilization during hummingbird flight GOLLER, B.*; ALTSHULER, D.L.; Univ. of California, Riverside; Univ. of California, Riverside bgoll001@ucr.edu Animal visual systems provide important feedback used for target localization, distance measurement, and the maintenance of stability during flight behavior. Both insect and avian flyers rely heavily on visual cues, but most of […]

Meeting Abstract 72.3  Thursday, Jan. 6  Multisensory Integration in Shark Feeding Behavior GARDINER, Jayne M*; ATEMA, Jelle; HUETER, Robert E; MOTTA, Philip J; University of South Florida; Boston University Marine Program; Mote Marine Laboratory; University of South Florida jmgardin@mail.usf.edu Feeding involves tracking, precisely localizing and striking at and capturing prey. In complex environments, animals rely on multiple […]

Meeting Abstract 72.2  Thursday, Jan. 6  Linking hydrodynamic stimuli and lateral line-mediated feeding behavior in a Lake Malawi cichlid BERGSTROM, MA*; WEBB, JF; University of Rhode Island; University of Rhode Island mbergstrom@my.uri.edu The mechanosensory lateral line system of fishes is thought to form hydrodynamic images of disturbances to flow immediately around the body and can mediate behaviors […]

Meeting Abstract 72.4  Thursday, Jan. 6  Gaining insight: visual feedback control in the hawkmoth Manduca sexta. FECHKO, AS*; HINTERWIRTH, AJ; DANIEL, TL; University of Washington; University of Washington; University of Washington ambersf@uw.edu Animals acquire and process sensory information to control motion in complex environments. In the hawkmoth Manduca sexta both visual and mechanosensory information are critical components […]

Meeting Abstract 72.1  Thursday, Jan. 6  Convergent Evolution of an Adaptive Phenotype in the Mechnosensory Lateral Line System: It’s not that Simple WEBB, JW*; ALBERG, T; Univ. of Rhode Island; Univ. of Rhode Island jacqueline_webb@mail.uri.edu The mechanosensory lateral line system of fishes plays critical roles in a variety of behavioral contexts including prey detection, predator avoidance, communication […]

Meeting Abstract 72.6  Friday, Jan. 6  Real-Time Modulation of Egg Size in an Altricial Bird SOCKMAN, K.W.; Univ. of North Carolina, Chapel Hill kws@unc.edu The size of a female’s eggs can affect the size of her offspring, her survival, and her lifetime reproductive success. Female birds modulate egg size according to several factors, such as diet and […]

Meeting Abstract 72.3  Friday, Jan. 6  Neural androgens regulate paternal care in a polygamous sex changing fish PRADHAN, DS*; SOLOMON-LANE, TK; WILLIS, MC; GROBER, MS; Georgia State Univ., Atlanta; Georgia State Univ., Atlanta; Georgia State Univ., Atlanta; Georgia State Univ., Atlanta dpradhan1@student.gsu.edu In many vertebrates, changes in circulating androgens regulate critical aspects of the breeding season. In […]

Meeting Abstract 72.2  Friday, Jan. 6  Male Removal Experiments Support the Biparental Care Hypothesis for the Evolution of Monogamy in Ranitomeya imitator. TUMULTY, J. P.*; SUMMERS, K.; East Carolina University; East Carolina University tumultyj09@students.ecu.edu Levels of parental investment by each sex are important factors in determining the mating system of a species. Selection for biparental care can […]
