Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...

Soviet Atheism and Russian Orthodox Strategies of Resistance, 1917–1932

Creator:: Husband, William B.
Abstract:: When the Bolsheviks came to power in Russia in 1917, party leaders under-stood well that a thorough social transformation lay between them and the full realization of long-term revolutionary objectives. The seizure of political authority and even a proposed redistribution of economic goods and services would not themselves create citizens...

Scaling of thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] resistivity-current isotherms at low fields: Implications for vortex phase transitions and universality

Creator:: Roberts, J. M., Brown, Brandon, Tate, Janet, Xi, X. X., and Mao, S. N.
Abstract:: We have investigated a second-order phase transition of the vortex lattice in thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] from 1 mT to 1 T applied magnetic fields. The dc resistivity-current density data for each field exhibit critical scaling consistent with a second-order vortex-liquid to vortex-solid phase transition. The high-field data support the vortex-glass...

Rocky intertidal oceanography: an association between community structure and nearshore phytoplankton concentration

Creator:: Menge, Bruce A., Daley, Bryon A., Wheeler, Patricia A., and Strub, P. Ted
Abstract:: On Oregon coastal rocky shores, filter‐feeders were relatively abundant and macrophytes were relatively scarce at Strawberry Hill, whereas opposite abundance patterns occurred at Boiler Bay. To determine whether nearshore oceanographic differences were associated with these patterns, we made shore‐based measurements of nutrient and Chl a concentrations. We used a three‐level...

Decomposition of Basamid in Douglas-fir heartwood: Laboratory studies of a potential wood fumigant

Creator:: Forsyth, Paul G. and Morrell, Jeffrey J.
Abstract:: Basamid (3,5-dimethyl-l,3,5,2H-tetrahydrothiadiazine-2-thione), a crystalline powder first used as a soil sterilant, has shown promise as a wood fumigant. This chemical decomposes to methylisothiocyanate (MITC), the primary active ingredient, as well as other products; but the rate of decomposition in wood is too slow to be effective unless certain catalysts are...

Foraminiferal faunal estimates of paleotemperature: Circumventing the no-analog problem yields cool ice age tropics

Creator:: Mix, Alan C., Morey, Ann E., Pisias, Nicklas G., and Hostetler, Steven W.
Abstract:: The sensitivity of the tropics to climate change, particularly the amplitude of glacial‐to‐interglacial changes in sea surface temperature (SST), is one of the great controversies in paleoclimatology. Here we reassess faunal estimates of ice age SSTs, focusing on the problem of no‐analog planktonic foraminiferal assemblages in the equatorial oceans that...

Benthic-Pelagic Links and Rocky Intertidal Communities: Bottom-Up Effects on Top-Down Control?

Creator:: Menge, Bruce A., Daley, Bryon A., Wheeler, Patricia A., Dahlhoff, Elizabeth, Sanford, Eric, and Strub, P. Ted
Abstract:: Insight into the dependence of benthic communities on biological and physical processes in nearshore pelagic environments, long considered a ``black box,'' has eluded ecologists. In rocky intertidal communities at Oregon coastal sites 80 km apart, differences in abundance of sessile invertebrates, herbivores, carnivores, and macrophytes in the low zone were...

Kinetic and Spectroscopic Analysis of the Inactivating Effects of Nitric Oxide on the Individual Components of Azotobacter vinelandii Nitrogenase

Creator:: Hyman, Michael R., Seefeldt, Lance C., Morgan, Vance, Arp, Daniel J., and Mortenson, Leonard E.
Abstract:: The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2) for 1 h with stoichiometries of 4- and 8-fold molar excesses of NO to Av2 dimer resulted in a complete loss of...

Stage duration estimation for Calanus populations, a modelling study

Creator:: Miller, Charles B. and Tande, Kurt S.
Abstract:: Population dynamics of Calanus finmarchicus have been modelled using very finely divided representation of the stock according to age-within-stage, in the manner of models developed by C. S. Davis, A. Sciandra, F. Carlotti and others. A key assumption of the model is that development rate is relatively insensitive to food-limitation,...
