GROSS, T.N.; MANZON, R.G.*; Univ. of Regina, Biology; Univ. of Regina, Biology richard.manzon@uregina.ca The lamprey appears to be the one vertebrate that contradicts the well-established anuran model of an increase in thyroid hormone (TH) concentrations […]

Meeting Abstract P1.127  Sunday, Jan. 4  Identification and Distribution of Octopamine in Ganglia and Innervated Organs of Crassostrea virginica SAMUEL, D.*; LAGARES, E.; CARROLL, M.A.; CATAPANE, E.J.; Medgar Evers College dtalented18@aol.com Octopamine is a biogenic amine which was first identified in the octopus. It has been well studied in arthropods and a few gastropods serving as a […]

Meeting Abstract P1.145  Sunday, Jan. 4  IMMUNOFLUORESCENCE LOCALIZATION OF AQUAPORIN DURING SALINITY ADAPTATION KAPPER, M.A.*; DEPAOLO, C.; Central Connecticut State Univ., New Britain kapper@ccsu.edu During adaptation to changes in salinity osmoconforming intertidal and estuarine molluscs utilize a comprehensive suite of strategies to maintain osmotic homeostasis. Behavioral methods temporarily delay contact between cells and altered environmental salinities while […]

Meeting Abstract P1.105  Sunday, Jan. 4  Hunting strategies of the mexican tetra fish Astyanax mexicanus larva STREETS, Amy*; SOARES, Daphne; univeristy of maryland; univeristy of maryland daph@umd.edu The emergence of new species-specific behaviors is only possible due to the evolutionary malleability of neural circuits. In the tetra fish Astyanax mexicanus, we find a particularly good window into […]

Meeting Abstract P1.86  Sunday, Jan. 4  How the development and microstructure of toe pad morphology reflect habitat specialization in Anolis lizards ST. LOUIS, J*; SANGER, TJ; HSIEH, T; Harvard Univeristy; Harvard University; University of Florida tsanger@oeb.harvard.edu Squamate lizards have repeatedly evolved specialized adhesive toe pads (lamellae) which provide superior clinging ability to the groups that posses them. […]
