Meeting Abstract P1.111  Wednesday, Jan. 4  Morphological variation in the pharyngeal jaw apparatus of Cypriniformes RADE, CM*; HERNANDEZ, LP; George Washington University; George Washington University cristinarade@gmail.com Cypriniformes is a morphologically diverse order of teleosts characterized by a novel pharyngeal jaw apparatus (PJA). While perciform pharyngeal jaws of various fish groups, including cichlids, haemulids, and labrids have been […]

Meeting Abstract P1.110  Wednesday, Jan. 4  Morphological variation in the palatal organ of Cypriniformes COSTANTINI, KE*; HERNANDEZ, LP; George Washington University phernand@gwu.edu Cypriniform fishes are characterized by a number of trophic novelties that likely played an important role in the success of the group. These novelties include a unique mechanism of premaxillary protrusion, hypertrophied lower pharyngeal jaws, […]

Meeting Abstract P1.95  Wednesday, Jan. 4  Morphological correlates of vocal traits in a clade of Neotropical catfishes (Siluriformes: Doradidae and Auchenipteridae): an adaptive radiation driven by vocal traits? KAATZ, I.M.*; STEWART, D.J.; SUNY-ESF Syracuse NY ingridmkaatz1@yahoo.com Signal divergence can drive speciation events. We found phylogenetic shifts in disturbance sound and vocal morphology traits at the genus level […]

Meeting Abstract P1.180  Wednesday, Jan. 4  Memory use as a possible mechanism for over-land movements in Eastern Painted turtles (Chrysemys picta picta): behavioral and neurological evidence PROVINE, SR*; O’MALLEY, H; KROCHMAL, AR; ROTH, TC; Kenyon College; Washington College; Washington College; Kenyon College rotht@kenyon.edu Aquatic turtles leave the water and traverse terrestrial habitats during oviposition, nesting or when […]

Meeting Abstract P1.36  Wednesday, Jan. 4  Mechanisms that Underlie Fasting-Associated Growth Cessation and Lipid Catabolism in Rainbow Trout (Oncorhynchus mykiss) BERGAN, H.E.; SHERIDAN, M.A.*; North Dakota St. Univ., Fargo mark.sheridan@ndsu.edu In this study, we used rainbow trout (Oncorhynchus mykiss) to identify the cellular mechanisms involved with growth cessation and lipid catabolism during periods of fasting. Fish were […]

Meeting Abstract P1.51  Wednesday, Jan. 4  Mechanisms of H+ and Ammonia Excretion in Exercising Blue Crabs, Callinectes sapidus BOOTH, C.E.*; HENRY, R.P.; Eastern Conn. State Univ.; Auburn Univ. booth@easternct.edu David Towle made seminal contributions to our understanding of ion transport across the crustacean gill epithelium, including the discovery of an apical electrogenic 2Na+/H+ exchanger (2NHE). Gill ion […]

Meeting Abstract P1.175  Wednesday, Jan. 4  Mapping developmentally dynamic synaptic inputs on motor neurons in zebrafish YAN, Q.*; DALLMAN, J. E.; University of Miami; University of Miami yanqing@bio.miami.edu During development, motor neurons must integrate thousands of excitatory and inhibitory interneuron inputs to produce essential rhythmic motor behaviors, therefore, functional motor behaviors require a balance between excitation and […]
