M.; Iowa State University, Ames, IA; Iowa State University, Ames, IA; Iowa State University, Ames, IA davidef@iastate.edu http://www.jeanneserb-lab.org Recent transcriptome analysis of scallops eyes and mantle from our lab has shown that scallops have a […]
Seeing without eyes Opsins and the evolution of photodetection in basal metazoans
Meeting Abstract 74-1 Wednesday, Jan. 6 08:00 Seeing without eyes: Opsins and the evolution of photodetection in basal metazoans BABONIS, L.S.*; MARTINDALE, M.Q.; Univ of Florida, Whitney Lab; Univ of Florida, Whitney Lab babonis@whitney.ufl.edu Opsins are photosensitive proteins that mediate the detection of light in photoreceptive tissues. Although they were originally thought to be restricted to the […]
Organized Water Addressing the Paradoxes of Acellular Bodies in Ctenophores
Meeting Abstract 74-3 Wednesday, Jan. 6 08:30 Organized Water: Addressing the Paradoxes of Acellular Bodies in Ctenophores TOWNSEND, J.P.*; SWEENEY, A.M.; University of Pennsylvania; University of Pennsylvania townj@mail.med.upenn.edu In the genomic era, we know that the earliest-branching animal phyla include ctenophores, sponges, and cnidarians. Intriguingly, these animals all share bodies that are more amorphous, acellular materials by […]
Expression and spectral analysis of two Gq-opsins from the mantle and the eyes of the scallop Placopecten magellanicus
Meeting Abstract 74-5 Wednesday, Jan. 6 09:00 Expression and spectral analysis of two Gq-opsins from the mantle and the eyes of the scallop Placopecten magellanicus SERB, J.M.*; HARLEY, A.; FAGGIONATO, D.; Iowa State Univ.; Iowa State Univ.; Iowa State Univ. serb@iastate.edu Despite having complex mirror eyes and showing mantle shadow response, the molecular details of scallop light […]
Do warning signals exploit an evolutionary constraint on insect visual acuity
Meeting Abstract 74-7 Wednesday, Jan. 6 09:30 Do warning signals exploit an evolutionary constraint on insect visual acuity? BRANDLEY, N*; CAVES, E; JOHNSEN, S; Colorado College; Duke University; Duke University nicholas.brandley@coloradocollege.edu http://nickbrandley.weebly.com/ Insects often have refined color and polarization vision, however their compound eyes have poor visual acuity because the small lens of individual ommatidia are diffraction-limited. […]
Coral opsins photosensitivity and partial characterization of five opsins from Acropora millepora
Meeting Abstract 74-4 Wednesday, Jan. 6 08:45 Coral opsins: photosensitivity and partial characterization of five opsins from Acropora millepora MASON, B.M.*; MILLER, D.J.; KOYANAGI, M.; TERAKITA, A.; Stanford University; James Cook University; Osaka CIty University; Osaka CIty University bmason2@stanford.edu Reef-building corals lack even basic visual structures, yet display notable photosensitivities. Light influences tentacle movement, regulates circadian clocks, […]
A Comparative Study of Copepod Phototaxis Modern vs Ancestral Photic Conditions
Meeting Abstract 74-2 Wednesday, Jan. 6 08:15 A Comparative Study of Copepod Phototaxis: Modern vs. Ancestral Photic Conditions MA, X.; JOHNSON, K.B.*; Florida Institute of Technology; Florida Institute of Technology johnson@fit.edu A comparative taxonomic approach is used to test the phototactic Sensitivity Hypothesis (SH), i.e. that light response reflects habitat photic conditions. Alternatively, if a species has […]
Physical and Computational Models of Spider Web Vibrations
Meeting Abstract 73-1 Wednesday, Jan. 6 08:00 Physical and Computational Models of Spider Web Vibrations OTTO, A.W.; ELIAS, D.O.; HATTON, R.L.*; Oregon State Univ.; Univ. of California, Berkeley; Oregon State Univ. Ross.Hatton@oregonstate.edu Web-building spiders tend to have poor eyesight and rely on web vibrations for situational awareness. Web-borne vibrations are used to determine the location of prey, […]
