Meeting Abstract 35.1  Jan. 5  Regeneration in benthic ctenophores (Platyctenida) DUBUC, Timothy R; University of Hawaii Manoa dubuc@hawaii.edu Coeloplana and Vallicula species have a unique derived lifestyle compared to their pelagic relatives, including: a benthic habitat, loss of ctene rows, and a flattened oral/aboral body. Adult benthic ctenophores have a complex gastrovascular system laced with a rich […]

Meeting Abstract 35.5  Jan. 5  Peripheral nervous system development in the ascidian Ciona intestinalis ZELLER, Robert W.; San Diego State University rzeller@sciences.sdsu.edu Current hypotheses postulate that the ancestral bilaterian nervous originated as a basiepidermal nerve net that was interspersed with sensory neurons. During bilaterian evolution, this nerve net was independently centralized in both protostomes and in the […]

Meeting Abstract 35.3  Jan. 5  Invagination of ascidian endoderm is preceded by apical contraction, but driven by active shortening of cells SHERRARD, K. M.; University of Washington kmsherra@u.washington.edu Invagination is a fundamental mode of morphogenesis whereby a sheet of cells autonomously generates forces causing itself to buckle inwards. Contraction of the apical (outer) cell cortex is the […]

Meeting Abstract 35.2  Jan. 5  Embryogenesis and metamorphosis of Aurelia aurita HARTENSTEIN, Volker*; YUAN, David; NAKANISHI, Nagayasu; JACOBS, David K.; UCLA; UCLA; UCLA; UCLA; UCLA volkerh@mcdb.ucla.edu We observed morphogenesis of the Aurelia aurita from embryogenesis, through the planula to early polyp using markers for nuclei (sytox), actin/myofibrils (phalloidin), neurons (Tyrosinated tubulin, FMRFamide, 5HT), dividing cells (Phosphohistone) cell […]

Meeting Abstract 34.5  Jan. 5  SoxE genes in development and evolution of the pharynx MCCAULEY, D.W.; University of Oklahoma dwmccauley@ou.edu The neural crest is a defining characteristic of vertebrates that gives rise to many characters specific to vertebrates and are considered a hallmark of vertebrate evolution. In gnathostome vertebrates, derivatives of the neural crest include the jaws […]

Meeting Abstract 34.6  Jan. 5  Mechanical and Bird Flight. LANDRY, S.O.; State University of New York, Binghamton slandry@binghamton.edu The fathers of heavier than air flight from Leonardo Da Vinci down to the Wright Brothers gained many of their insights from observing the flight of birds. Is it possible that students of the evolution of flight, in return, […]

Meeting Abstract 34.4  Jan. 5  Lessons Learned from the �Intelligent Design� Trial PADIAN, Kevin; University of California, Berkeley kpadian@berkeley.edu On December 20, 2005, Judge John E. Jones III ruled in a Harrisburg, Pennsylvania courtroom that �intelligent design� is not accepted as science by the scientific community and could not be taught as such in public school science […]

Meeting Abstract 34.2  Jan. 5  Defining the promoter region of a second insulin gene in zebrafish PAPASANI, MR*; HALTERMAN, K; HILL, RA; University of Idaho; University of Idaho; University of Idaho papasani@uidaho.edu A second insulin gene, insb has been identified and shown to be expressed in the pancreas, head and blastomeres during embryonic development of zebrafish. Towards […]

Meeting Abstract 34.3  Jan. 5  Analysis of Glycerol 3-Phosphate Dehydrogenase and Sarco/Endoplasmic Reticulum Calcium Ion Channel ATPase for Potential Use in Deep Metazoan Phylogeny CAMPBELL, Terry/G*; GAREY, James/R; University of South Florida; University of South Florida tcampbe2@chuma.cas.usf.edu Genetic sequence data have been used to analyze phylogenetic relationships for over a decade and numerous data sets have been […]

Meeting Abstract 34.1  Jan. 5  An androgen-receptor signaling system found in the sea lamprey, Petromyzon marinus BRYAN, M.B.*; SCOTT, A.P.; LI, W.; Michigan State University; The Centre for Environment, Fisheries and Aquaculture Science; Michigan State University bryanmar@msu.edu The nuclear receptor superfamily is ancient lineage of transcription factors, which are predominately activated by small ligands. As part of […]
