Plant nutrient losses in runoff from conservation tillage corn
L.L. McDowell,K.C. McGregor +1 more
TL;DR: Conservation tillage in north Mississippi, U.S.A., reduced total (sum of solution and sediment) plant nutrient losses in runoff from corn, even though solution nitrogen (N) and phosphorus (P) concentrations in runoff were greater than from conventional-till and sediments were enriched severalfold in N and P as discussed by the authors.
Sampling and Sample-handling Protocols for GEOTRACES Cruises
Gregory A. Cutter,Per Andersson,Lou Codispoti,Peter Croot,Roger Francois,Maeve C. Lohan,Hajime Obata,Michiel M Rutgers van der Loeff +7 more
TL;DR: The GEOTRACES Standards and Intercalibration (S&I) Committee is charged with ensuring that the data generated during GEOTrACES are as precise and accurate as possible, which includes all the steps from sampling to analysis as mentioned in this paper.
Journal ArticleDOI
Reproductive exhaustion in shrimp (Penaeus vannamei) reflected in larval biochemical composition, survival and growth
TL;DR: It is demonstrated that reproductive exhaustion of shrimp spawners occurs and it becomes largely evident as time after ablation increases: spawner exhaustion is reflected in the quality of the larvae produced.
Journal ArticleDOI
Intensive aggregate formation with low vertical flux during an upwelling-induced diatom bloom
Thomas Kiørboe,Peter Tiselius,Betty Mitchell-Innes,Jørgen L.S. Hansen,André W. Visser,Xavier Mari +5 more
TL;DR: The authors' observations provide only partial support for the population retention hypothesis because aggregate buoyancy and N. scintillans grazing efficiently reduced the vertical flux of aggregates in this system.
Journal ArticleDOI
Distribution and Diversity of Archaeal and Bacterial Ammonia Oxidizers in Salt Marsh Sediments
TL;DR: The results expand the distribution of AOA to salt marshes, and the high numbers of Aoa at some sites suggest that salt marsh sediments serve as an important habitat for AOA, which was always more abundant than β-AOB based on quantitative PCR of amoA genes.
