SOUTHWOOD, A.L.*; HIGGINS, B.M.; BRILL, R.W.; SWIMMER, J.Y.; University of Hawaii; NOAA Fisheries; NOAA Fisheries; NOAA Fisheries: Aquatic chemoreception in loggerhead sea turtles: behavioral responses to food and a novel chemical We developed an assay to investigate the behavioral responses of loggerhead sea turtles, Caretta caretta, to chemical stimuli presented underwater. Captive-reared juvenile loggerhead turtles […]

JACKMAN, W.R.*; STOCK, D.W.; University of Colorado at Boulder: Transgenic analysis of the mechanism of cypriniform oral tooth loss We are interested in the developmental genetic mechanisms responsible for evolutionary change in fish dentition, and are specifically investigating the mechanism of oral tooth loss in cypriniform fishes. In a survey of genes with known tooth […]

HURLEY, IA*; SCEMAMA, JL; PRINCE, VE; Organismal Biology & Anatomy, The University of Chicago; Dept. of Biology, The University of Chicago; Organismal Biology & Anatomy, The University of Chicago: The mechanism and consequences of duplicate gene preservation � a comparison of hoxb1 duplicates across teleost fish Vertebrate evolution is characterized by gene/genome duplication events, and […]

JIMENEZ, Lizandra; Adelphi University: Preliminary Phylogeny of the Tilefishes Based Upon Their Cytochrome b and 16S Gene Sequences Tilefishes are found worldwide. Tilefishes are presently thought by some to be monophyletic (i.e. belong to one family, Branchiostegidae, comprised of two subfamilies, Malacanthinae and Branchiosteginae). Another alternative theory is that the tilefishes consist of two separate […]

SCHLUETER, P.J.*; DUAN, C.; University of Michigan, Ann Arbor; University of Michigan, Ann Arbor: Overlapping and distinct functions of the duplicated zebrafish insulin-like growth factor-1 receptor (IGF-1R) genes in early development The process of gene duplication is a major contributor to the genetic diversity of vertebrate genomes, and the driving force behind a complicated process […]

WISE, S. B.*; STOCK, D. W.; University of Colorado at Boulder: Bone morphogenetic protein expression, regulation, and function in teleost tooth development and evolution Bone morphogenetic proteins (Bmps) have been shown to be important in tooth development in the mouse and the evolution of dentition in rodents and birds, but little comparable data is available […]

CROTWELL, P.L.*; MABEE, P.M.; Univ. of South Dakota, Vermillion; Univ. of South Dakota, Vermillion: A comparative analysis of gene expression patterns conserved in segmentation of fish and tetrapod skeletons Much skeletogenesis in zebrafish occurs at �late stages� for which there are few tools to test gene function. The study of mutants, for example, is limited […]

Meeting Abstract 46.4  Jan. 6  Volume of song control nuclei in a songbird with near monomorphic song: Influences of sex and season JAWOR, Jodie*; MACDOUGALL-SHACKLETON, Scott, A.; University of Southern Mississippi, Hattiesburg, MS, USA; University of Western Ontario, London, Ontario, Canada jodie.jawor@usm.edu Song production and learning is controlled in songbirds by a series of brain nuclei called […]

Meeting Abstract 46.5  Jan. 6  Song culture affects noradrenergic activity in the auditory telencephalon of female starlings SALVANTE, K.G.*; SOCKMAN, K.W.; Univ. North Carolina, Chapel Hill; Univ. North Carolina, Chapel Hill ksalvante@unc.edu In some songbird species, the spectro-temporal properties of a male’s song may reflect his quality and hence suitability as a prospective mate. Thus, females make […]

Meeting Abstract 46.2  Jan. 6  Does Testosterone Mediate Parental Care in Female Dark-eyed Juncos? O’NEAL, D.M.*; REICHARD, D.G.; PAVLIS, K; KETTERSON, E.D.; Indiana University, Bloomington; Saint Mary’s College of Maryland; University of Guelph; Indiana University, Bloomington daoneal@indiana.edu Hormonal manipulations allow us to create novel phenotypes in order to learn how existing phenotypes evolve and why they persist.
