Meeting Abstract 70-4  Sunday, Jan. 5 14:15 – 14:30  Snapping shrimp see through transparent armor KINGSTON, ACN*; SPEISER, DI; University of South Carolina; University of South Carolina acnahm@gmail.com Snapping shrimp have specialized armor, termed the orbital hood, that covers their head and eyes. It has been proposed that orbital hoods protect the heads of snapping shrimp but […]

Meeting Abstract 70-6  Sunday, Jan. 5 14:45 – 15:00  On the Laws of Haller and Leuckart OR Does visual resolution scale with velocity and size in animals? HEESY, CP; Midwestern University, AZ cheesy@midwestern.edu Vertebrate eyes, even with differences due to ecology, (generally) scale hypometrically with body size – as a result of a relationship called Haller’s Law. […]

Meeting Abstract 70-7  Sunday, Jan. 5 15:00 – 15:15  Measurement of cephalopod polarization patterns with color video-polarimetry and computer vision techniques. BRADY, PC*; GARCIA, M; HERNANDEZ, T; AALUND, M; GRUEV, V; CUMMINGS, ME; University of Texas at Austin; University of Illinois at Urbana Champaign; University of Texas at Austin; University of Texas at Austin; University of Illinois […]

Meeting Abstract 70-3  Sunday, Jan. 5 14:00 – 14:15  Light intensity and eye size dependent spatio-temporal visual abilities in Drosophila melanogaster PALAVALLI-NETTIMI, R*; THEOBALD, JC; Florida International University, Miami, FL; Florida International University, Miami, FL rpalaval@fiu.edu https://rvndrpn.wixsite.com/ravindra The fruit fly Drosophila melanogaster is sensitive to light and prefers certain light intensities. But lab-reared flies are often tested […]

Meeting Abstract 70-2  Sunday, Jan. 5 13:45 – 14:00  How our perceptual and cognitive biases may influence our study of animal vision JOHNSEN, S*; CAVES, EM; Duke Univ.; Exeter Univ. sjohnsen@duke.edu https://opticsoflife.org/ It has long been appreciated (and celebrated) that certain species have sensory capabilities that humans do not share, for example ultraviolet vision and magnetoreception. What […]

Meeting Abstract 70-1  Sunday, Jan. 5 13:30 – 13:45  Binocular stereopsis in cuttlefish improves prey targeting. WARDILL, TJ*; FEORD, RC; SUMNER, ME; PUSDEKAR, S; KALRA, L; GONZALEZ-BELLIDO, PT; University of Minnesota; University of Cambridge; University of Minnesota; University of Minnesota; University of Minnesota; University of Minnesota twardill@umn.edu To assess depth information, some animals utilize the disparity between […]

CHAN, S.-M.; GU, P.-L.: The study of shrimp CHH/MIH/GIH gene family: gene structure, expression and biological assay of recombinant neuropeptides The crustacean CHH/MIH/GIH neuropeptide family constitutes a group of important hormone that regulates important processes such as molting, glucose metabolism and reproduction. The characterization of these neuropeptides has attracted much attention due to their potential […]

HOLFORD, K.C.*; BORST, D.W.: The effects of sinus gland extracts on transcript levels of farnesoic acid O-methyl transferase (MeT) in the lobster mandibular organ. Methyl farnesoate (MF) appears to have important roles in the regulation of crustacean reproduction, molting, and behavior. In decapod crustaceans, the mandibular organ (MO) is the principle site of MF synthesis […]

LINDER, C.J.; TSUKIMURA, B.*: Inhibitory effects of methyl farnesoate (MF) on the reproductive development of tadpole shrimp (TS), Triops longicaudatus To identify a reproductive regulator for the invasive TS, T. longicaudatus, the hormone MF was administered to growing juveniles. To administer MF, aquatic vectors (Artemia nauplii) incubated in 0.05% albumin and 5 �g/ml MF for […]

Tilden, A.R.*; Schwartz, J.; McGann, L.: Influence of Melatonin on Hemolymph Metabolites in the Fiddler Crab Uca Pugilator Melatonin levels were measured in the eyestalks of fiddler crabs (Uca pugilator) acclimated to a LD 12:12 photoperiod, constant dark, and constant light. Melatonin cycled with a photophase peak during the LD 12:12 photoperiod. The cycle persisted […]
