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.

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 […]

Gene expression during development and diapause in a vertebrate extremophile
Meeting Abstract 74-2 Saturday, Jan. 7 08:15 – 08:30 Gene expression during development and diapause in a vertebrate extremophile ROMNEY, A LT*; PODRABSKY, J E; Portland State University; Portland State University arom2@pdx.edu http://www.pdx.edu/podrabsky-lab/ The annual killifish, Austrofundulus limnaeus, has adapted to survive in harsh and unpredictable environments by entering diapause during embryonic development. Diapause is a pre-programmed […]
Environmental fluctuations and host skin bacteria shift survival advantage between frogs and their fungal pathogen
Meeting Abstract 74-6 Saturday, Jan. 7 09:15 – 09:30 Environmental fluctuations and host skin bacteria shift survival advantage between frogs and their fungal pathogen LONGO, AV*; ZAMUDIO, KR; University of Maryland and Smithsonian Institution; Cornell University avlongo@umd.edu Fluctuating environments can modulate host-pathogen interactions by providing a temporary advantage to one of the interacting organisms. However, we know […]
