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 35.5  Friday, Jan. 4  Time course of changes in plasma hormone concentrations and expression of hormone receptors and osmotic stress transcription factor 1 in the gill of Mozambique tilapia following transfer to a hyperosmotic environment BREVES, J.P.*; FOX, B.K.; PIERCE, A.L.; HIRANO, T.; GRAU, E.G.; Dept. of Molecular Biosciences and Bioengineering & Hawaii Institute of […]

Meeting Abstract 35.4  Friday, Jan. 4  Short- term mechanism of seawater adaptation in Mozambicus tilapia (Oreochromis mossambicus): The effect of salinity exposure on cell cycle and Na/K ATPase content in gill cells assessed using laser scanning cytometry (LSC) KAMMERER, B.D.**; SARDELLA, B.A.; K�LTZ, D.; University of California, Davis; University of California, Davis; University of California, Davis bdkammerer@ucdavis.edu […]

Meeting Abstract 35.3  Friday, Jan. 4  Short term tolerance to changes in environmental salinity by the longhorn sculpin, Myoxocephalus octodecimspinosus . HYNDMAN, Kelly/A*; EVANS, David/H; Univ. of Florida, Gainesville; Mount Desert Biological Laboratory, Maine khyndman@zoo.ufl.edu The bottom-dwelling longhorn sculpin, Myoxocephalus octodecimspinosus, is a marine fish that fisherman have found in estuaries during high tide, suggesting that they […]

Meeting Abstract 35.6  Friday, Jan. 4  Proteome Fingerprint of the Stress Environment in the Renal Papilla GABERT, B.J.**; K�LTZ, D.; University of California, Davis bjlandgraf@ucdavis.edu The mammalian kidney generates a large and variable osmotic gradient to generate urine with a much higher osmotic concentration than blood. This vital function of the kidney is only possible at the […]

Meeting Abstract 35.1  Friday, Jan. 4  Changes in protein expression in the dogfish shark rectal gland following natural feeding DOWD, W. W.*; WOOD, C. M.; KAJIMURA, M.; WALSH, P. J.; K�LTZ, D.; Univ. of California, Davis; McMaster University, Hamilton, Ontario, and Bamfield Marine Sciences Centre, British Columbia; McMaster University, Hamilton, Ontario, and Bamfield Marine Sciences Centre, British […]

Meeting Abstract 35.5  Monday, Jan. 5  The presence of community structure varies with spatial scale in Lake Malawi cichlid fishes. PARNELL, N.F.*; STREELMAN, J.T.; Georgia Institute of Technology; Georgia Institute of Technology gth877n@mail.gatech.edu A long-standing issue in ecology is the existence and related causes of structure in natural communities. Here, we use null model simulations of species […]

Meeting Abstract 35.2  Monday, Jan. 5  The interaction of sexually and naturally selected traits in the adaptive radiations of cichlid fishes SALZBURGER, Walter; University of Basel, Switzerland walter.salzburger@unibas.ch The question of how genetic variation translates into organismal diversity has puzzled biologists for decades. Despite recent advances in evolutionary and developmental genetics the mechanisms that underlie adaptation, diversification […]

Meeting Abstract 35.4  Monday, Jan. 5  Light environment limits gene expression in rapidly evolving cichlid radiations HOFMANN, C.M.**; SEEHAUSEN, O.; CARLETON, K.L.; University of Maryland chofma1@umd.edu Sensory adaptation to the light environment has been repeatedly demonstrated in opsin genes. However, recent work suggests that changes in gene expression may also play a large part in tuning visual […]
