Stoichiometric imbalance in rates of nitrogen and phosphorus retention, storage, and recycling can perpetuate nitrogen deficiency in highly-productive reservoirs
nitrogen phosphorus retention storage
2014/11/28
We measured the nutrient stoichiometry of inputs, outputs, retention, storage, and recycling in three seasonally
nitrogen (N)-deficient reservoirs by incorporating watershed mass balances with measur...
A discrepancy between predictions of saturating nutrient uptake models and nitrogen-to-phosphorus stoichiometry in the surface ocean
saturating nutrient uptake models nitrogen-to-phosphorus stoichiometry the surface ocean
2014/4/17
We derive a simple prediction about euphotic zone N : P stoichiometry from a large class of models that use saturating nutrient uptake functions to characterize N and P acquisition by phytoplankton. T...
Nitrogen and phosphorus inputs control phytoplankton growth in eutrophic Lake Taihu, China
Nitrogen phosphorus inputs control phytoplankton growth eutrophic Lake Taihu
2014/4/16
Lake Taihu (Taihu) is the third largest freshwater lake in China and an important drinking water, fishing, and tourism resource for Jiangsu Province. Recent toxic cyanobacterial blooms caused by exces...
The effects of rainfall on the distribution of inorganic nitrogen and phosphorus in Discovery Bay, Jamaica
rainfall on the distribution inorganic nitrogen phosphorus in Discovery Bay Jamaica
2014/5/5
We sought to define the ambient concentrations of inorganic nitrogen and phosphorus in the coastal waters of Discovery Bay, Jamaica, and to investigate the effects of groundwater and rainfall on those...
Responses of estuarine and coastal marine phytoplankton to nitrogen and phosphorus enrichment
estuarine coastal marine phytoplankton
2014/4/30
A cross-ecosystem comparison of data obtained from 92 coastal zone ecosystems worldwide revealed a strong
positive response of marine phytoplankton biomass to nutrient enrichment that is highly consi...
Growth rates of Antarctic krill, Euphausia superba: Comparison of the instantaneous growth rate method with nitrogen and phosphorus stoichiometry
Growth rates of Antarctic krill Euphausia superba Comparison of the instantaneous growth rate method with nitrogen phosphorus stoichiometry
2014/5/19
Zooplankton growth rates are hard to measure directly, and proxy measurements are desirable to encompass the variety of species and scales of interest. The growth rate hypothesis of stoichiometric the...
Responses of seagrass communities to fertilization along a gradient of relative availability of nitrogen and phosphorus in a carbonate environment
Responses of seagrass communities to fertilization a gradient of relative availability nitrogen and phosphorus carbonate environment
2014/5/19
Patterns of relative nutrient availability in south Florida suggest spatial differences regarding the importance of nitrogen (N) and phosphorus (P) to benthic primary producers. We did a 14-month in s...
Mass-transfer-limited nitrogen and phosphorus uptake by stream periphyton: A conceptual model and experimental evidence
Mass-transfer-limited nitrogen phosphorus uptake stream periphyton conceptual model experimental evidence
2014/5/19
We conducted flow-tank experiments to examine nitrate (NO3) and dissolved reactive phosphorus (DRP) uptake by stream periphyton over a wide range of near-bed velocities and turbulence levels. Our aims...
The stoichiometry of dissolved organic carbon, nitrogen, and phosphorus release by a planktonic grazer, Daphnia
dissolved organic carbon nitrogen phosphorus release
2014/5/19
We examined the relationship between Daphnia release rates and ratios of dissolved organic carbon (DOC),
nitrogen (N), and phosphorus (P) and the elemental composition of algal food. We constructed a...
Nitrogen and phosphorus requirements of an Alexandrium minutum bloom in the Penzé estuary, France
Nitrogen and phosphorus Alexandrium minutum Penze estuary France
2014/5/19
During an intense (up to 33 X 106 cells L-1) Alexandrium minutum bloom in the Penze′ estuary (France), total NO3, NH4, and PO4 requirements of the bloom were, respectively, 184, 25, and 20 μmol L-1, w...
The role of dust in supplying nitrogen and phosphorus to the Southeast Mediterranean
The role of dust supplying nitrogen and phosphorus Southeast Mediterranean
2014/5/27
This study assesses the role of the atmospheric dry fallout as a source of new nitrogen and phosphorus to the surface Levantine seawater. Leaching experiments of inorganic nitrogen (LINO3-, LINH4+) an...
Carbon, nitrogen, and phosphorus budgets for a shallow subtropical coastal embayment (Moreton Bay, Australia)
Carbon nitrogen phosphorus shallow subtropical coastal embayment
2014/5/27
Average annual carbon, nitrogen, and phosphorus budgets were constructed for Moreton Bay. Primary production was the dominant source of carbon (by two orders of magnitude), N fixation was the dominant...
