Creator:: Smith, Robert L., Huyer, Adriana, Godfrey, J. Stuart, and Church, John A.
Abstract:: The Leeuwin Current in the Indian Ocean off Western Australia differs from the other major eastern boundary currents, e.g., California Current, since it flows rapidly poleward against the prevailing equatorward wind. The first large-scale study of the Leeuwin Current was conducted between North West Cape (22°S) and the south-western corner...

Abstract:: Large-scale poisoning events are common to scavenging bird species that forage communally, many of which are in decline. To reduce the threat of poisoning and compensate for other persistent threats, management, including supplemental feeding, is ongoing for many reintroduced and endangered vulture populations. Through a longitudinal study of lead exposure...

Creator:: Arp, Daniel J. and Burris, Robert H.
Abstract:: The kinetic mechanism of the unidirectional H2-oxidizing hydrogenase from soybean nodule bacteroids has been investigated with highly purified enzyme. Measurements of the K, for H2 vary from 0.97 to 2.6 pM, and the K,,, for methylene blue varies from 6 to 17 pM. With H2 and methylene blue as substrates,...

Abstract:: Negative impacts of CO₂-induced ocean acidification on marine organisms have proven to be variable both among and within taxa. For fishes, inconsistency confounds our ability to draw conclusions that apply across taxonomic groups and highlights the limitations of a nascent field with a narrow scope of study species. Here, we...

Abstract:: Seasonal cycles of coastal wind stress, adjusted sea level (ASL), shelf currents, and water temperatures off the west coast of North America (35°N to 48°N) are estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records (9-34 years) of monthly ASL indicate that these two harmonics adequately...

Abstract:: OBJECTIVES: A key challenge for achieving universal water access in Sub-Saharan Africa is poor sustainability of water schemes. Previous studies have posited factors that may lead to failed schemes; however, empirical data are lacking. METHODS: We conducted direct observations of water sources and interviewed water committee members about governance in...

Abstract:: Stable oxygen and carbon isotope δ[superscript 18]O and δ[superscript 13]C analyses of otoliths are becoming increasingly common in fisheries science and management. However, little is known about the statistical properties of isotopic data and few attempts have been made to explore appropriate statistical methods that could be used for otolith...

Creator:: Friesen, Christopher R., Uhrig, Emily J., and Mason, Robert T.
Abstract:: Polyandry is a source of sexual conflict and males often try to limit female promiscuity. Consequently, male manipulation of receptivity via antiaphrodisiacs and copulatory plugs that prevent female remating can be a source of sexual conflict. This sexual conflict may be intensified when females must remate for fertility insurance. Male...

Creator:: Waldbusser, George G., Marinelli, Roberta L., Whitlatch, Robert B., and Visscher, Pieter T.
Abstract:: We tested the role of benthic infaunal functional diversity in regulating the biogeochemistry of nearshore sediments using laboratory microcosms. Single and multispecies assemblages of deposit-feeding polychaetes (Clymenella torquata, Spio setosa, and Leitoscoloplos fragilis) were used, and fluxes of oxygen and phosphate, as well as profiles of oxygen and pH in...

Creator:: Sinton, C. W., Hitchen, K., and Duncan, Robert A.
Abstract:: At the submerged margins of the North Atlantic, andesitic to dacitic and basaltic volcanic rocks occur together. The silicic rocks were derived by processes requiring the presence of continental crust (crustal anatexis and/or contamination of mafic magmas) while the majority of the basaltic lavas had little or no contact with...
