REILLY, C.R.L.; Stanford University: Thermal noise limits visual sensitivity in the Rockfish (genus Sebastes). An animal’s ability to behave appropriately in response to the dynamic events in its local environment depends on the ability of its sensory systems to detect and encode those events. This necessitates an informational relationship through which salient features of the […]

BLEVINS, E.L.*; JOHNSEN, S.; Duke University; Duke University: Spatial vision in the echinoid genus Echinometra Although eyes are generally considered necessary for image resolution, a diffuse photoreceptive system with directional sensitivity may also have this ability. Two species of the echinoid genus Echinometra were tested for spatial vision by examining their ability to locate and […]

KIHSLINGER, Rebecca L*; NEVITT, Gabrielle A; Univ. of California, Davis: Sending fish to preschool: Early enrichment affects brain and behavioral phenotype in salmon. It is well established that rearing environment plays a critical role in the development of phenotype. This role may be more pronounced in organisms that experience a dramatic change in environmental conditions, […]

SPRAYBERRY, Jordanna D. H.; University of Washington: Response of descending visual interneurons in the hawkmoth Manduca sexta to flower-like stimuli Vision is a vital sensory system in the control of animal flight. Hawkmoths rely on vision to guide flower tracking, a behavior that compensates for flower motion during feeding bouts. What visual information about a […]

HAUBER, ME; THEUNISSEN, FE; University of Auckland; University of California, Berkeley: Neural bases of species discrimination in female songbirds Acoustic perception learning by both females and males is widespread among songbirds, including many species in which only males sing. Previous work from our laboratory demonstrated response selectivity for conspecific song over synthetic stimuli in auditory […]

WEBB, J.F.; HERMAN, J.L.; KETTEN, D.R.; Villanova University; Villanova University; Woods Hole Oceanographic Institution: Ear and Otolith Morphology in a Prominent Group of Coral Reef Fishes with a Putative Specialization for Enhanced Sound Reception Specialized ear morphology is correlated with enhanced hearing in fishes with otophysic connections (ear-swim bladder linkages). Butterflyfishes of the genus Chaetodon […]

KOLB, EM; RHODES, JS; JANOWSKY, A; GARLAND, T; Univ. of Calif., Riverside; Oregon Health and Sciences Univ. ; Oregon Health and Sciences Univ. ; Univ. of Calif., Riverside: Dopamine Receptor and Transporter Density in the Caudate and Prefrontal Cortex of Mice Selectively Bred for High Wheel Running Animals that exhibit high locomotor activity must have […]

MENSINGER, A.F.*; PALMER, L.M.; University of Minnesota Duluth and Marine Biological Laboratory; University of Minnesota Duluth and Marine Biological Laboratory: Detection of free swimming prey via the lateral line in the toadfish, Opsanus tau Inductive neural telemetry was used to record from microwire electrodes chronically implanted into the anterior lateral line nerve of the toadfish, […]

WOLF, Mary C; DALY, Kevin C; MOORE, Paul A; Bowling Green State University; West Virginia University; Bowling Green State University : Central nervous system processing of odor stimuli: the effect of stimulus duration on information coding Two major issues facing sensory ecologists are how olfactory information is coded in the nervous system and how that […]

CASKEY, J.L.; BAUER, R.T.; Univ. of Louisiana, Lafayette; Univ. of Louisiana, Lafayette: Behavioral Tests of a Contact Pheromone in Male Recognition of Receptive Females in the Shrimp Palaemonetes Pugio Palaemonetes pugio is a small estuarine shrimp found along the Atlantic and Gulf coasts. Males recognize (suddenly attempt to grasp and to mate) newly molted (postmolt) […]
