Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea
Elemental composition marine Prochlorococcus Synechococcus ecological stoichiometry
2014/5/21
The elemental composition of marine cyanobacteria is an important determinant of the ecological stoichiometry in low-latitude marine biomes. We analyzed the cellular carbon (C), nitrogen (N), and phos...
Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/4
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
Ecological stoichiometry: An elementary approach using basic principles
basic principles Ecological stoichiometry
2014/4/2
Based on the observation that organism-specific elemental content creates ecologically relevant mismatches
such as between plant and animal tissue, it was postulated—and experimentally verified—that ...
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 deposition, catchment productivity, and climate as determinants of lake stoichiometry
Nitrogen deposition catchment productivity climate as determinants of lake stoichiometry
2014/4/17
Nearly 1000 Norwegian lakes in catchments with low human activity were surveyed. By covering a wide range of nitrogen (N) deposition (0.1-2 g m-2 yr-1) along a latitudinal and climatic gradient, we cl...
Benthic biogeochemical cycling, nutrient stoichiometry, and carbon and nitrogen mass balances in a eutrophic freshwater bay
Benthic biogeochemical cycling nutrient stoichiometry carbon and nitrogen mass balances eutrophic freshwater bay
2014/4/18
Green Bay, while representing only ~7% of the surface area and ~1.4% of the volume of Lake Michigan, contains one-third of the watershed of the lake, and receives approximately one-third of the total ...

Carbon sequestration and stoichiometry of motile and nonmotile green algae
Carbon sequestration nonmotile green algae
2014/4/17
Actively motile, flagellated phytoplankton taxa often exploit vertical gradients in the availability of light and
nutrients. The ability to move actively usually goes along with low investment in str...
