Meeting Abstract 95.2  Wednesday, Jan. 7  Stuck between a rock crab and a hard place: phenotypic responses to multiple predators in a marine snail. BOURDEAU, Paul/E; Stony Brook University bourdeau@life.bio.sunysb.edu I examined the single and combined effect of chemical cues from crabs and seastars, two predators with contrasting attack modes, on the shell morphology of the marine […]

Meeting Abstract 95.4  Wednesday, Jan. 7  Sex allocation and reproductive success in simultaneously hermaphroditic acorn barnacles HOCH, JM; Stony Brook University jmatthoch@gmail.com Semibalanus balanoides is a simultaneously hermaphroditic acorn barnacle that mates with its neighbors using a long, agile penis. Sex allocation theory (Charnov 1980, 1982) predicts that simultaneous hermaphrodites maximize total reproductive success by increasing allocation […]

Meeting Abstract 95.5  Wednesday, Jan. 7  Dynamics of Shrimp Goby Mutualism in the Caribbean LYONS, P.J.; Stony Brook Univ. plyons@life.bio.sunysb.edu In the mutualism between burrowing alpheid shrimp and gobies, the goby gains shelter and the shrimp benefits from the alarm against predators generated by flutters of the gobys caudal fin. In the Caribbean, the shrimp, Alpheus floridanus, […]

Universidad de Quintana Roo; Evolutionary Biology & Population Genetics, Universidad de Quintana Roo luismejia@uqroo.mx We made a histological analysis of hepatopancreas structure of three crayfishes species. Two from karst […]

Meeting Abstract 95.4  Thursday, Jan. 7  Measuring the heritability of plasticity in a colonial model hydroid, Hydractinia symbiolongicarpus RYAN, C.A*; DUDGEON, S.R.; California State University, Northridge; California State University, Northridge carly.ryan.16@csun.edu The influence of environmental variation on the phenotypes of individuals has long been of interest to researchers. In species which demonstrate a high level of phenotypic […]

Meeting Abstract 95.2  Thursday, Jan. 7  How do chitons see their world? A new sensory organ in basal molluscs (Polyplacophora: Lepidopleurida) SIGWART, JD; Queen’s University Belfast j.sigwart@qub.ac.uk Polyplacophoran molluscs (chitons) are “primitive” animals that have a simple nerve system of non-ganglionised longitudinal nerve cords and no cephalised sense organs. Two sensory structures in the pallial cavity have […]
