Meeting Abstract 80.1  Friday, Jan. 7  A computational modelling perspective on buccal expansion dynamics and water flow patterns in suction feeding fish VAN WASSENBERGH, S*; AERTS, P; Univ. Antwerpen; Univ. Antwerpen sam.vanwassenbergh@ua.ac.be By performing a sudden expansion of the mouth cavity while approaching a prey, suction feeders generate a flow of water that draws the prey into […]

Meeting Abstract 80.1  Friday, Jan. 6  Thermal and hypoxic gene expression in the mayfly (Centroptilum triangulifer). KIM, K.S.; FUNK, D.H.; BUCHWALTER, D.B.*; NC State University; Stroud Water Research Center; NC State University david_buchwalter@ncsu.edu Despite the widespread use of aquatic insects in biomonitoring programs, there are currently no established model organisms for ecophysiological studies of stream insects. The […]

Meeting Abstract 80.2  Friday, Jan. 6  Recovery from hypoxia and hypercapnic hypoxia: Impacts on the transcription of key antioxidant genes in the shrimp Litopenaeus vannamei. DARLING, CL*; BURNETT, LE; BURNETT, KG; College of Charleston; College of Charleston; College of Charleston darlingcl@gmail.com The Pacific whiteleg shrimp, Litopenaeus vannamei, inhabits coastal estuarine waters which are prone to intermittent bouts […]

Meeting Abstract 80.3  Friday, Jan. 6  Changes in Pulmonary Surfactant in Deer Mice (Peromyscus maniculatus) at High Altitude DIAZ, S.*; THALER, C. D.; SHIRKEY, N. J.; BROWN, T.; CARDULLO, R.

Meeting Abstract 80.4  Friday, Jan. 6  Are all snakes made equal: handling hypoxic conditions. CAMPBELL, JC*; COBB , VA; Middle Tennessee State University jc3n@mtmail.mtsu.edu Fossorial animals are generally exposed to different environmental conditions than their terrestrial counterparts. Because of enclosed surroundings with little air space and reduced air flow, hypoxic and hypercapnic conditions (LO2/HCO2) would be expected, […]

Meeting Abstract 80.4  Sunday, Jan. 6  Turbulence from a microorganism’s perspective: Does the open ocean feel different than a coral reef? PEPPER, R.E.*; VARIANO, E.A.; KOEHL, M.A.R.; Univeristy of California, Berkeley; Univeristy of California, Berkeley; Univeristy of California, Berkeley rachel.pepper@berkeley.edu Microorganisms in the ocean live in turbulent flows. Swimming microorganisms navigate through the water (e.g. larvae land […]

Meeting Abstract 80.1  Sunday, Jan. 6  Indefatigable: Erect Coralline Alga Is Immune To Fatigue DENNY, MW*; MARTONE, PT; Stanford University; University of British Columbia mwdenny@stanford.edu Intertidal organisms are subjected to intense hydrodynamic forces as waves break on shore. These repeated insults can cause an organism’s structural materials to fatigue and fail even though no single force would […]

Meeting Abstract 80.3  Sunday, Jan. 6  Hydrodynamic forces and moments on microscopic aquatic animals DOLINAJEC, T.H.*; KOEHL, M.A.R.; Univ. of California, Berkeley; Univ. of California, Berkeley dolinajec@berkeley.edu Many aquatic animals are microscopic and interact with the water around them at a range of velocities in which both viscous and inertial forces are important. In spite of their […]

Meeting Abstract 80.2  Sunday, Jan. 6  Do Wave Impact Forces Limit the Size of Intertidal Organisms? JENSEN, M.M.*; DENNY, M.W.; Hopkins Marine Station, Stanford University; Hopkins Marine Station, Stanford University mmjensen@stanford.edu Although intertidal organisms are generally much smaller than their terrestrial and subtidal counterparts, the biological and physical mechanisms that limit size have not been determined. While […]

Meeting Abstract 80.5  Sunday, Jan. 6  Analysis of the fluid flow through the complex internal respiratory structures of an extinct Paleozoic echinoderm HUYNH, TL*; EVANGELISTA, D; MARSHALL, CR; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley huynhtony@berkeley.edu Blastoids were a group of stalked, sessile echinoderm preserved in rocks that span the middle Ordovician […]
