Meeting Abstract S10-1.3 Saturday, Jan. 7 Genetic variation: are barnacles so strange? WARES, J.P.*; EWERS, C.; University of Georgia jpwares@uga.edu Environmental heterogeneity, both spatial and temporal, is likely to leave indicators in the patterns of nucleotide variation across genomes. These patterns are often assessed with statistical tests that rely on assumptions about the mechanisms of natural selection, […]

Costs and benefits of alternative defensive morphologies and population variation in phenotypic plasticity of the barnacle Chthamalus fissus
Meeting Abstract S10-1.1 Saturday, Jan. 7 Costs and benefits of alternative defensive morphologies and population variation in phenotypic plasticity of the barnacle Chthamalus fissus JARRETT, JN; Central Connecticut State University jarrettj@ccsu.edu The barnacle Chthamalus fissus resides in the high intertidal along the coast of Southern California and Northern Baja California. Juvenile C. fissus exposed to the spine […]
Barnacles and biofouling – a brief history and summary of current research approaches and results
Meeting Abstract S10-1.5 Saturday, Jan. 7 Barnacles and biofouling – a brief history and summary of current research approaches and results HOLM, E.R.; Naval Surface Warfare Center, Carderock Division eric.holm@navy.mil Biofouling, the accretion of organisms on submerged surfaces, has been the bane of ship operators for at least 2500 years. Accumulation of biofouling increases the frictional resistance […]
Barnacle Glue, is curing like blood clotting
Meeting Abstract S10-1.6 Saturday, Jan. 7 Barnacle Glue, is curing like blood clotting? RITTSCHOF, D.*; DICKINSON, G.H.; WAHL, K.J.; BARLOW, D.; ORIHUELA, B.; VEGA, I.E.; EVERETT, R.; Duke University; University of Pittsburgh; Naval Research Laboratory; Naval Research Laboratory; Duke University Marine Laboratory; University of Puerto Rico; Naval Research Laboratory ritt@duke.edu We hypothesized that barnacle glue curing is […]
Watch your steps Opsins and photoreceptors in sea urchin tube feet
Meeting Abstract S10-1.5 Monday, Jan. 7 Watch your steps! Opsins and photoreceptors in sea urchin tube feet ULLRICH-LUTER, Esther; ARNONE, Maria Ina*; Univ. of Bonn and Natural History Museum, Berlin; Stazione Zoologica Anton Dohrn, Napoli miarnone@szn.it Sea urchins, due to their derived morphological body plan, have long been considered to be of limited value regarding the reconstruction […]
Transcriptomics and the evolution of stomatopod visual systems
Meeting Abstract S10-1.6 Monday, Jan. 7 Transcriptomics and the evolution of stomatopod visual systems PORTER, M.L..*; CALDWELL, R.L.; OAKLEY, T.H.; CRONIN, T.W.; University of South Dakota; University of California, Berkeley; University of California, Santa Barbara; University of Maryland Baltimore County Megan.Porter@usd.edu Stomatopod crustaceans have complex and diverse visual systems, containing unique features that exist in no other […]
The control of cnidocyte discharge by light
Meeting Abstract S10-1.4 Monday, Jan. 7 The control of cnidocyte discharge by light PLACHETZKI, D/C; UC Davis plachetzki@ucdavis.edu Cnidocytes facilitate both sensory and secretory functions among cnidarians and have been heralded as the most complex animal cell type. Cnidocyte discharge is known to integrate both chemical and mechanical cues from the environment, but, despite more than a […]
Physiological genomics of color vision in butterflies
Meeting Abstract S10-1.7 Monday, Jan. 7 Physiological genomics of color vision in butterflies BRISCOE, Adriana*; YUAN, Furong; University of California, Irvine abriscoe@uci.edu Butterflies evolve mimetic wing coloration under selection from predators. Unless butterfly eyes have adaptations for discriminating mimetic color variation there is a risk of confusing mimics from potential mates for the butterflies themselves. The genus […]
Opsins in brachiopod embryos and larvae
Meeting Abstract S10-1.3 Monday, Jan. 7 Opsins in brachiopod embryos and larvae PASSAMANECK, Y.J.*; MARTINDALE, M.Q.; University of Hawaii; University of Hawaii yale@hawaii.edu In the larvae of most protostome invertebrates, detection of directional light is facilitated by simple pigmented eyes containing rhabdomeric photoreceptor cells. To extend the understanding of protostome eye evolution, we have investigated photoreceptor morphology, […]
Mechanism of phototaxis in marine zooplankton and origin of simple visual circuits
Meeting Abstract S10-1.2 Monday, Jan. 7 Mechanism of phototaxis in marine zooplankton and origin of simple visual circuits JéKELY, G; Max Planck Institute for Developmental Biology, Spemannstrasse 35, 72076 Tübingen, Germany gaspar.jekely@tuebingen.mpg.de Eyes and nervous systems evolved in a marine environment at the dawn of animal life and diversified during the Cambrian explosion, one of the most […]
