Temperature and nutrient supply interact to control nitrogen fixation in oligotrophic streams: An experimental examination
Temperature and nutrient supply control nitrogen fixation oligotrophic streams
2014/5/5
We performed two experiments to examine how temperature and nutrients interact to control dinitrogen (N2) fixation, chlorophyll a (Chl a) biomass, and community composition of periphyton in subalpine ...
The importance of submarine groundwater discharge to the near shore nutrient supply in the Gulf of Aqaba (Israel)
submarine groundwater discharge near shore nutrient supply the Gulf of Aqaba
2014/5/4
We used two short-lived radium isotopes (223Ra, 224Ra) and a mass balance approach applied to the radium activities to determine the nutrient contribution of saline submarine groundwater discharge to ...
Physical pathways of nutrient supply in a small, ultraoligotrophic arctic lake during summer stratification
Physical pathways nutrient supply
2014/5/4
During the ice-free period in the Arctic, the thermal structure and mixing dynamics of small lakes change with the passing of air masses. In Toolik Lake, Alaska, stable warm air masses during the ice-...

substratum type nutrient supply
2014/5/19
We investigated the effect of benthic substratum type (sand and rocks) and nutrient supply (N and P) on biofilm
structure and heterotrophic metabolism in a field experiment in a forested ...
