Meeting Abstract 23.7  Saturday, Jan. 4 14:45  The role of vertebral morphology in a fish eat fish world ACKERLY, KL*; WARD, AB; McGill University; Adelphi University kerri.ackerly@mail.mcgill.ca Many selective factors work together to determine the optimal body morphology to maximize swimming performance in fishes. The vertebral column is one of the most important morphological elements in determining […]

Meeting Abstract 23.2  Saturday, Jan. 4 13:45  Symbionts are couch potatoes: rounded bodies and loss of swimming in symbiotic “swimming” crabs. EVANS, N*; PAULAY, G; Univ. of Florida evansnat@ufl.edu Most members of the brachyuran family Portunidae swim with an efficiency unmatched by any other clade of crabs. This has been attributed to a number of morphological adaptations […]

Meeting Abstract 23.4  Saturday, Jan. 4 14:15  Implications for the origin of baleen as revealed by palatal vascularization of a gray whale calf (Cetacea, Mysticeti) EKDALE, E.G.; San Diego State Univ eekdale@projects.sdsu.edu The origin of baleen in Mysticeti was a major transition during cetacean evolution. All extant baleen whales are edentulous in adulthood, but teeth develop in […]

Meeting Abstract 23.8  Saturday, Jan. 4 15:00  Functional Morphology of Antennal Sensory Organs of the House Cricket, Acheta domesticus (L.) SHIELDS, V.D.C.*; CHARLES, C.D.; ARNOLD, N.S.; Towson University; Towson University; Towson University vshields@towson.edu House crickets, Acheta domesticus (L.), have paired antennae that bear many sensory organs (sensilla). These sensilla allow them to gain information about olfactory, gustatory, […]

Meeting Abstract 23.6  Saturday, Jan. 4 14:30  Development and Growth of the Medullary Cavity in the Rostrum of Paddlefish (Polyodon spathula) ROBERTSON, J.; Westminster College, New Wilmington, PA robertjc@westminster.edu The rostrum is not present in newly hatched paddlefish, but soon grows to about one-third the total body length of juvenile fish, and is known to have electroreceptive […]

Meeting Abstract 23.2  Sunday, Jan. 4 13:45  Proteomic profiles of regenerating tissue in the ascidian Ciona intestinalis IRVINE, SQ; Univ. of Rhode Island steven.irvine@uri.edu http://cels.uri.edu/Irvine/Irvine_lab/Home.html Regeneration may be viewed as the activation of a non-embryonic developmental program in response to injury. This program necessarily involves a change in the expression profile of proteins in order to rebuild […]

Meeting Abstract 23.1  Sunday, Jan. 4 13:30  Plasma treatment accelerates tail regeneration in tadpoles Xenopus laevis RIVIE, A.*; MANZO, W.; MARTUS, K.; MENON, J.; William Paterson University; William Paterson University; William Paterson University; William Paterson University riviea@student.wpunj.edu Atmospheric pressure plasma have found large application in regenerative medicine. Presently, we investigated the effect of plasma on wound healing […]

Meeting Abstract 23.4  Sunday, Jan. 4 14:15  A phylum-wide survey reveals multiple gains of regenerative ability in nemerteans ZATTARA, E.E.*; NORENBURG, J.L.; BELY, A.E.; Smithsonian Institution, NMNH-IZ; Smithsonian Institution, NMNH-IZ; University of Maryland, College Park ezattara@gmail.com http://invertebrates.si.edu/zattara.htm The ability to regenerate new body parts is broadly distributed across animals, yet this ability varies widely among them. To […]

Meeting Abstract 23-2  Monday, Jan. 4 13:45  What’s up – in the water column? Linking spawned embryos with adult chitons in two separate oceans EMLET, RB; Univ. Oregon remlet@uoregon.edu By using molecular sequences of COI genes (barcoding) from chiton eggs or embryos collected as plankton and from adults collected in the field, we have identified time of […]
