Journal ArticleDOI
Improving the fluorometric ammonium method: matrix effects, background fluorescence, and standard additions
Brad W. Taylor,Christine F. Keep,Robert O. Hall,Benjamin J. Koch,Lusha M. Tronstad,Alexander S. Flecker,Amber J. Ulseth +6 more
TL;DR: In this article, the authors proposed a new method for measuring a sample's background fluorescence that includes the background signal of the reagent or its interaction with the matrix constituents of the sample.
Journal ArticleDOI
The relationship between phytoplankton biovolume and chlorophyll in a deep oligotrophic lake: decoupling in their spatial and temporal maxima
Marisol Felip,Jordi Catalan +1 more
TL;DR: The results show that changes in chlorophyll content per cell occur as a photoacclimation response along a vertical profile, and point out a component of the successional trends which appear in a phytoplankton growth phase in a lake.
Journal ArticleDOI
Development and Validation of an Estuarine Biotic Integrity Index
Linda A. Deegan,John T. Finn,Suzanne G. Ayvazian,Cheryl A. Ryder-Kieffer,John P. Buonaccorsi +4 more
TL;DR: The Estuarine Biotic Integrity Index is suggested to be a useful indicator of estuarine ecosystem status because it reflects the relationship between anthropogenic alterations inEstuarine ecosystems and the status of higher trophic levels.
Journal ArticleDOI
Utilization of ammonium and nitrate during austral summer in the Scotia Sea
TL;DR: The nitrogenous nutrition of the phytoplankton in the Scotia Sea was investigated with 15 N tracer techniques during the austral summer of 1979 as discussed by the authors, and the results showed that phyto-ankton showed a consistent preference for NH 4 + utilization relative to NO 3 −.

Dissimilatory reduction of nitrate to ammonium, not denitrification or anammox, dominates benthic nitrate reduction in tropical estuaries
Liang F. Dong,Milika Naqasima Sobey,Milika Naqasima Sobey,Cindy J. Smith,Iman Rusmana,Wayne N. Phillips,Andrew W. Stott,A. Mark Osborn,David B. Nedwell +8 more
TL;DR: In this article, benthic denitrification (DN) and dissimilatory reduction of nitrate to ammonium (DNRA) using the isotope-pairing technique in three tropical estuaries in Thailand (Mae Klong), Indonesia (Cisadane), and Fiji (Vunidawa-Rewa) during rainy, dry, and intermediate seasons along the salinity gradient of each estuary.
