Effects of fertilization and development of the common mussel Mytilus edulis after long-term exposure to a nonionic surfactant
Marine Biology - Tập 33 - Trang 17-20 - 1975
Å Granmo, G. Jørgensen
Common mussels (Mytilus edulis L.) were exposed over a 5-month period to low-level concentrations (0.5 to 1.5 ppm) of a nonionic surfactant. Upon maturation at the end of this period, spawning ability was examined. Fertilization occurred at low-level concentrations (0.1 to 2.0 ppm) of the surfactant, and was most successful for gametes from the long-term controls and the highest long-term concentr...... hiện toàn bộ
The undulating oceanographic recorder — A new instrument system for sampling plankton and recording physical variables in the euphotic zone from a ship underway
Marine Biology - Tập 32 - Trang 85-97 - 1975
R. H. Bruce, J. Aiken
The prototype Undulating Oceanographic Recorder Mark I is an instrumented towed vehicle which can be programmed to undulate between a minimum depth of 8 m and a selected maximum depth between 15 and 70 m, with an undulation length between 3 and 30 km, at any speed between 7 and 15 knots (3.6 to 7.7 m/sec). It takes a continuous series of plankton samples, each integrated over the undulation depth ...... hiện toàn bộ
Meiofauna versus macrofauna as a food resource in a tropical intertidal mudflat
Marine Biology - Tập 166 - Trang 1-11 - 2019
Pierre-Yves Pascal, Pierrick Bocher, Christel Lefrançois, Hien T. Nguyen, Johan Chevalier, Christine Dupuy
Evaluations of the functioning of benthic marine food webs could be improved by quantifying organic matter fluxes from the meiofauna to higher trophic levels. In this study, we measured the simultaneous ingestion of meiofauna and macrofauna by common dwellers of a tropical intertidal mudflat on the coast of Amazonia. The meiofauna and macrofauna (tanaid) communities of a tropical intertidal mudfla...... hiện toàn bộ
Contribution of living and degrading kelp to coastal iodine fluxes
Marine Biology - Tập 162 - Trang 1727-1738 - 2015
Udo Nitschke, Sophie Dixneuf, Matthias Schmid, Albert A. Ruth, Dagmar B. Stengel
Laminaria digitata forms locally extensive and ecologically important kelp beds in northern temperate regions. Its sporophytes retain large quantities of iodine which, when released into seawater (as iodide, I−) and into air (as molecular iodine, I2), have the potential to contribute significantly to coastal iodine biogeochemical processes. Here, standing crop of a living ...... hiện toàn bộ
Seascape modeling of southern giant petrels from Patagonia during different life-cycles
Marine Biology - Tập 164 - Trang 1-14 - 2017
Gabriela S. Blanco, Noela Sánchez-Carnero, Juan Pablo Pisoni, Flavio Quintana
Presence-only models such as Ecological Niche Factor Analysis (ENFA) compare distributions of environmental variables and species, generating habitat suitability (HS) maps. Here, we determined the factors affecting distribution of southern giant petrels (SGP) from northern Patagonian colonies (Isla Arce: 45° 00ʹS; 65°29′W, and Isla Gran Robredo: 45°08ʹS; 66°03′W) using ENFA, improving estimates of...... hiện toàn bộ
Effect of near-bottom currents on detection of bait by the abyssal grenadier fishes Coryphaenoides spp., recorded in situ with a video camera on a free vehicle
Marine Biology - Tập 84 Số 1 - Trang 83-91 - 1984
Raymond R. Wilson, Kenneth L. Smith
Tube-worm-sediment relationships in populations of Pectinaria gouldii (Polychaeta: Pectinariidae) from Barnegat Bay, New Jersey, USA
Marine Biology - Tập 33 - Trang 255-264 - 1975
D. A. Busch, R. E. Loveland
Pectinaria gouldii (Verrill), which lives for 1 year in Barnegat Bay, New Jersey, constructs over its lifetime a conical tube of increasingly large sand grains, regardless of surrounding sediment characteristics. However, the rate of increase of mean grain size of the tube and the population density of the worm vary with sediment type. The distribution of this species is limited by sediment compo...... hiện toàn bộ
Determination of δ13C and δ15N and trophic fractionation in jellyfish: implications for food web ecology
Marine Biology - Tập 161 - Trang 473-480 - 2013
Isabella D’Ambra, Ruth H. Carmichael, William M. Graham
Application of stable isotope analysis (SIA) in jellyfish allows definition of trophic patterns not detectable using gut content analysis alone, but analytical protocols require standardization to avoid bias in interpreting isotopic data. We determined δ13C and δ15N in Aurelia sp. from the northern Gulf of Mexico (30°00′N, 89°00′W–30°24′N, 88°00′W) to define differences in stable isotope compositi...... hiện toàn bộ
