Inhibition of first cleavage modifies MAP kinase activity and embryonic patterning in squid
Meeting Abstract P2.45 Jan. 5 Inhibition of first cleavage modifies MAP kinase activity and embryonic patterning in squid. CRAWFORD, K.; St. Mary’s College of Maryland, MD and Marine Biological Laboratory, Woods Hole, MA kcrawford@smcm.edu Ablation and isolation experiments performed on gastropod embryos demonstrate that the D macromere plays a critical role in axial patterning as the founder […]
Influence of orientation and flow speed on feeding behavior and metabolism of the barnacle Semibalanus balanoides
Meeting Abstract P2.130 Jan. 5 Influence of orientation and flow speed on feeding behavior and metabolism of the barnacle Semibalanus balanoides LAKE, B.*; JOHNSON, A.S.; MAUCK, R.A.; Bowdoin College; Bowdoin College; Kenyon College blake@bowdoin.edu In areas of unidirectional flow intertidal barnacles settle oriented facing upstream within 90 degrees of the flow direction. Optimal foraging theory predicts […]
Influence of anesthesia methods on steroid levels in amphibians
Meeting Abstract P2.123 Jan. 5 Influence of anesthesia methods on steroid levels in amphibians WIDDER, P. D.**; HUSAK, J. F.; MOORE, I. T.; BELDEN, L. K.; Virginia Tech widder@vt.edu Few studies have examined the influence of anesthesia on steroid levels in amphibians, and these studies have been limited to the stress hormone corticosterone. However, if one aims […]
Induced plasticity and shell strength in the intertidal snail Nucella ostrina
Meeting Abstract P2.127 Jan. 5 Induced plasticity and shell strength in the intertidal snail Nucella ostrina PEARSON, E. L.; University of California, Davis (Current address: University of Redlands) ed_pearson@redlands.edu Phenotypic plasticity of the shells of molluscs is often induced by the presence of water-borne cues originating from predators, typically durophagous decapod crustaceans native to the range of […]
Individual variation and plasticity in egg size in multicolored Asian lady beetles (Harmonia axyridis)
Meeting Abstract P2.57 Jan. 5 Individual variation and plasticity in egg size in multicolored Asian lady beetles (Harmonia axyridis). PREVOLSEK, Jaime; WILLIAMS, Tony, D*; Simon Fraser University, Burnaby; Simon Fraser University, Burnaby tdwillia@sfu.ca Evolutionary theory predicts that individual females of iteroparous species should be selected for flexibility in egg (propagule) size such that they can adjust egg […]
Increased chemo-investigation of an atrazine-contaminated substrate in the terrestrial salamander, Plethodon shermani
Meeting Abstract P2.17 Jan. 5 Increased chemo-investigation of an atrazine-contaminated substrate in the terrestrial salamander, Plethodon shermani. LANZEL, S.L.*; WOODLEY, S.K.; Duquesne University; Duquesne University lanzels@duq.edu Atrazine is the most commonly used herbicide in the United States. In salmon, atrazine interferes with pheromonal communication by dampening the response of olfactory sensory neurons (Moore and Lower, 2001). By […]
Immunosenescence in a long-lived Seabird
Meeting Abstract P2.51 Jan. 5 Immunosenescence in a long-lived Seabird CERCHIARA, J.A.*; ZANGMEISTER, J.L.; HAUSSMANN, M.F.; MAUCK, R.A.; Kenyon College; Kenyon College; Kenyon College; Kenyon College, Bowdoin College cerchiaraj@kenyon.edu Life history theory predicts that long-lived species should invest heavily in maintenance systems affecting adult survival, however physiological systems deteriorate as a result of aging in most species. […]
How plant aggregation density affects fluid flow and particle settlement All that glitter is not gold
Meeting Abstract P2.142 Jan. 5 How plant aggregation density affects fluid flow and particle settlement: All that glitter is not gold YANG, S.*; CARRINGTON, E.; Univ. of Washington, Seattle; Univ. of Washington, Seattle sy3@u.washington.edu Sessile organisms modify their local fluid environments by changing mean velocity and turbulence. How these modifications affect local particle dispersion and settlement is […]
How environmental and physiological conditions influence escape behaviors in lizards A multifactor measure of risk
Meeting Abstract P2.8 Jan. 5 How environmental and physiological conditions influence escape behaviors in lizards: A multifactor measure of risk JORDAN IV, W.J.*; THAKER, M.; Indiana State University; Indiana State University wjjordaniv@hotmail.com Perception of predation risk is a major factor that influences antipredator tactics. Therefore, a good measure of antipredator behavioral responses could be an indicator of […]
