Meeting Abstract 62.5  Jan. 7  Acoustically-evoked immediate-early gene expression in the pallium of the t�ngara frog MANGIAMELE, L.A.*; BURMEISTER, S.S.; University of North Carolina, Chapel Hill lisaman@email.unc.edu The anuran auditory system is a good model for studying the neural mechanisms of sexual communication. Previous studies have focused on the role of the auditory midbrain and thalamus in […]

Meeting Abstract 61.2  Jan. 7  Interannual variability in the foraging behavior of California sea lions: behavioral responses to environmental variation KUHN, Carey E.*; COSTA, Daniel P.; University of California, Santa Cruz; University of California, Santa Cruz Kuhn@biology.ucsc.edu The California sea lion (Zalophus californianus) is an abundant predator along the west coast of the United States and populations […]

Meeting Abstract 61.6  Jan. 7  Individual-based foraging strategies in male California Sea Lions (Zalophus californianus) WEISE, M.J.*; COSTA, D.P.; UC Santa Cruz; UC Santa Cruz weise@biology.ucsc.edu Historically conspecifics were often treated as ecological equivalents in studies of foraging theory, but more recently the variation among individuals is no longer considered as irrelevant noise, but a focus of […]

Meeting Abstract 61.4  Jan. 7  Decorating behavior and predation: new insights from polychaetes and crustaceans BERKE, Sarah K*; WOODIN, Sarah A; Univ. of South Carolina; Univ. of South Carolina berke@biol.sc.edu Decorating behavior, in which animals actively attach foreign material to their bodies or their structures, occurs in 25% of the major metazoan phyla. Decorating is commonly assumed […]

Meeting Abstract 61.3  Jan. 7  Autotomy as a deep-sea squid defense BUSH, S.L.; University of California, Berkeley & MBARI stephalopod@berkeley.edu In oceanic midwaters animals are vulnerable to predation from all directions, therefore it is likely that a diversity of defensive tactics are employed by deep-sea organisms. One maneuver is to startle a predator upon attack such that […]

Meeting Abstract 60.1  Jan. 7  Sensitivity of utricular afferent fibers to intraspecific calling via inductive neural telemetry in free ranging oyster toadfish, Opsanus tau. MENSINGER, Allen F.; University of Minnesota Duluth amensing@d.umn.edu Male toadfish acoustically attract females to nesting sites by producing �boat-whistle� calls. To determine how the fish localize sound underwater, inductive neural telemetry was used […]

Meeting Abstract 59.2  Jan. 7  The esthetal canal system in chitons (Mollusca: Polyplacophora) and homologous structures in Lower Cambrian small shelly fossils. VINTHER, Jakob; Yale University jakob.vinther@yale.edu The esthetal canal system in chitons is one of the most complex canal systems within a mineralized matrix with both a sensory and secretory function. The esthete system is regarded […]

Meeting Abstract 59.5  Jan. 7  Early evolution of Monstersauria (Reptilia, Squamata) CONRAD, J.L.*; NORELL, M.A.; American Museum of Natural History, New York jconrad@amnh.org Monstersauria (beaded lizards, Gila monsters, and their fossil relatives) has a fossil record that extends back 100 million years (Ma) and includes taxa from North America, Europe, and eastern Asia. Most Cretaceous monstersaurs are […]
