PELIS, R.M.*; RENFRO, J.L.; Univ. of Connecticut, Storrs; Univ. of Connecticut, Storrs: Active Sulfate Secretion by the Intestine of Winter Flounder, Pleuronectes americanus Marine teleosts are hypoosmotic to their surrounding environment and must continuously drink seawater to avoid dehydration. It is widely accepted that water uptake across the marine teleost intestine is driven by active […]

Proteins characteristic of the adhesive mucus of molluscs and their potential role in determining gel function
SMITH, A.M.*; STARTZ, T.; RAHME, D.; PIERCE, C.; Ithaca College, Ithaca, NY: Proteins characteristic of the adhesive mucus of molluscs and their potential role in determining gel function. A variety of molluscs secrete adhesive forms of mucus that create powerful attachments. Research with limpets and periwinkle snails has demonstrated that the primary difference between these […]
Principally Continuous Flow in Gastropod Mantle Cavities
VOLTZOW, J.; Univ. of Scranton: Principally Continuous Flow in Gastropod Mantle Cavities The flow of water through a gastropod mantle cavity follows the same basic principle of continuity that describes flow through a series of pipes. Regions with the largest total cross-sectional areas should have the slowest flow rates and regions with the smallest cross-sectional […]
Odor Sampling In Wavy Environments How Does Ambient Flow Affect Olfactory Flicking In Stomatopods
MEAD, K.S.; Denison University: Odor Sampling In Wavy Environments: How Does Ambient Flow Affect Olfactory Flicking In Stomatopods? Many crustaceans detect odors from distant sources by using chemosensory sensilla (aesthetascs) on their antennules. Stomatopods facilitate odorant access by flicking their antennules, thus increasing the relative velocity of the water and improving odor molecule access to […]
More than one way to sniff a comparative analysis of palinurid lobster antennules
PATEK, S.N.*; GOLDMAN, J.A.; University of California, Berkeley; American Institute of Biological Sciences: More than one way to sniff: a comparative analysis of palinurid lobster antennules Lobsters �sniff� by flicking their antennular flagella. They discretely sample odors in the environment by rapidly closing the flagella, which permits water to flow through sensory hairs, and then […]
Chimney Formation and Plasticity in a Bryozoan
VON DASSOW, M.; Univ. of California, Berkeley: Chimney Formation and Plasticity in a Bryozoan How does fluid flow affect the growth of fluid transport systems? The sheet-like colonial bryozoan Membranipora membranacea is a good system for studying this question because it has a simple geometry and is amenable to experimental manipulation. Crowns of ciliated tentacles […]
Surviving the maelstrom morphology, size, and danger of dislodgement of intertidal algae
WOLCOTT, Bryce D.; Univ. of California, Berkeley: Surviving the maelstrom: morphology, size, and danger of dislodgement of intertidal algae Wave-induced water motion has been shown to influence both the size and shape of organisms on rocky shores. The morphology of many seaweeds, for example, varies with flow conditions, resulting in a reduction of the mechanical […]
Hydrodynamic consequences of buoyancy vs flexural stiffness in the tropical alga Turbinaria ornata
STEWART, Hannah/L; Univ. of California, Berkeley: Hydrodynamic consequences of buoyancy vs. flexural stiffness in the tropical alga Turbinaria ornata Benthic organisms maintain upright postures by high flexural stiffness (EI) or by buoyancy. An upright position in the water column can potentially increase mass transfer and light interception but may also expose sessile organisms to greater […]
Geographic and environmental variation in Bryconops cf melanurus (Ostariophysi Characidae) from the Brazilian Pantanal
SIDLAUSKAS, B. L.; CHERNOFF, B.; MACHADO-ALLISON, A.; University of Chicago and The Field Museum, Chicago, IL; University of Chicago and The Field Museum, Chicago, IL; Universidad Central de Venezuela, Caracas: Geographic and environmental variation in Bryconops cf. melanurus (Ostariophysi: Characidae) from the Brazilian Pantanal Morphometric analyses of 220 specimens of Bryconops cf. melanurus from the […]
Drag and flexibility in Chondrus crispus Stackhouse what drives the Vogel Number
BOLLER, M.L.*; CARRINGTON, E.; Univeristy of Rhode Island: Drag and flexibility in Chondrus crispus Stackhouse: what drives the Vogel Number? The reorientation of an intertidal alga with the flow of a crashing wave allows the alga to reduce drag by reducing the area projected into flow. This phenomenon, dubbed reconfiguration, manifests itself as a change […]
