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...
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...
Effects of the zebra mussel, an exotic freshwater species, on seston stoichiometry
Effects of the zebra mussel exotic freshwater species
