WETHEY, D. S.*; WOODIN, S. A; University of South Carolina, Columbia; University of South Carolina, Columbia: Secret Sounds of the Sediments: Infaunal Infrasound Burrowing by polychaetes, bivalves, and other large inhabitants of marine sediments is carried out by a variety of hydraulic mechanisms. We hypothesized that these activities would generate low frequency pressure waves, or […]

FINKE, GR; BAILLEY-BECHET, M; P. Univ. Cat�lica de Chile: Scaling of transient wave forces in Concholepas concholepas during the early stages of impact The mechanisms by which wave induced forces affect the biology and ecology of marine organisms have traditionally focused on hydrodynamic forces such as drag, lift and accelerational forces. Nonetheless, transient impingement forces […]

HELMUTH, Brian; STRICKLAND, Denise; Univ. South Carolina, Columbia; Univ. South Carolina, Columbia: Risky Business in the rocky intertidal: don’t get caught with your tide down Rocky intertidal invertebrates and algae are aquatic organisms that must contend with the rigors of the terrestrial environment during low tide. As such, they have emerged as potential bellwethers for […]

BRABY, C.E.*; LOPEZ, J.P.; CHANEY, M.L.; SOMERO, G.N.; Hopkins Marine Station, Stanford University; Hopkins Marine Station, Stanford University; Hopkins Marine Station, Stanford University; Hopkins Marine Station, Stanford University: Relative importance of stress physiology and recruitment pressure in determining local distribution patterns Recruitment patterns are known to play an important role in the population structure of […]

STEWART, Hannah L.; Univ. of California, Berkeley: Ontogenetic changes in tissue strength, buoyancy and reproductive output enhance dispersal by the rafting macroalga Turbinaria ornata Distributions of benthic macroalgae rely on dispersal distances of spores, gametes or detached pieces of fertile thalli. Many species of algae are buoyant and individuals detached from the substratum by hydrodynamic […]

MILLER, L. P.; Hopkins Marine Station, Stanford University: Functional significance of littorine snail “standing off” behavior for control of body temperature during aerial exposure Littorine snails living in the high intertidal zone must often endure high body temperatures during daytime low tides, which can put them near their physiological thermal tolerance limits. In order to […]

O’DONNELL, M.J.; MILLER, L.P.; , ; , ; , ; , ; Hopkins Marine Station; Hopkins Marine Station: Field measurements of mussel feeding time in the surf zone Organisms living in the intertidal zone must contend with both terrestrial and aquatic environments, frequently twice each day. Despite the fact that they must survive the stresses […]

SCHNEIDER, K.R.; NYLUND, K; HELMUTH, B.S.T.; Univ. of South Carolina; Univ. of South Carolina; Univ. of South Carolina: Does temperature regulate intertidal microhabitat distributions of Mytilus trossulus and M. galloprovincialis within San Francisco Bay? The rocky intertidal is considered one of the most physiological stressful environments and is, therefore, a model system to study species […]

CARRINGTON, E; University of Rhode Island: Disturbance to mussel beds on NE rocky shores: is it predictable? On temperate rocky coasts, mussels often form dense beds in the mid-intertidal zone that dominate primary space and provide secondary habitat for other organisms. The frequency and severity of disturbance to mussel beds therefore plays an important role […]

MOESER, G.M.*; CARRINGTON, E.; University of Rhode Island: Causes of seasonal variation in mussel attachment: Byssal thread production and decay The blue mussel, Mytilus edulis, maintains a strong attachment to the substrate in high energy environments by producing byssal threads. On Rhode Island shores, mussels increase attachment strength two-fold in winter in comparison to summer. […]
