Comparative responses of two dominant Antarctic phytoplankton taxa to interactions between ocean acidification, warming, irradiance, and iron availability
ocean acidification warming irradiance
2014/11/28
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis
antarctica (a prymnesiophyte) and Fragilariopsis cylindrus(a diatom) to a clustered matrix of th...

Tempe Fermentation of Whole Grain Barley Increased Human Iron Absorption and In Vitro Iron Availability
Iron absorption in vitro iron availability whole grain
2009/1/16
In this study, iron absorption from a tempe fermented whole-grain barley meal was measured, and results were compared to in vitro estimation of available iron from an equivalent meal. The tempe meal (...
Composting of Rice Straw and its Influences on Iron Availability in Calcareous Soil
Rice straw C/N ratio humic acid ferrous-Fe iron fraction grain yield
2010/11/9
Composting incubation and pot experiment were conducted to evaluate the nutritional status of
composted rice straw mixed with organic raw materials and assess the combined effect of compost and iron ...
Growth rates, half saturation constants, and silicate, nitrate, and phosphate depletion in relation to iron availability of four large open-ocean diatoms from the Southern Ocean
Growth rates half saturation constants silicate, nitrate phosphate depletion relation to iron availability four large open-ocean diatoms Southern Ocean
2014/5/19
Four large, open-ocean diatoms from the Southern Ocean (Actinocyclus sp., Thalassiosira sp., Fragilariopsis kerguelensis, and Corethron pennatum) were grown in natural (low iron) Southern ocean seawat...
Relationship of nitrogen isotope fractionation to phytoplankton size and iron availability during the Southern Ocean Iron RElease Experiment (SOIREE)
nitrogen isotope fractionation phytoplankton size iron availability the Southern Ocean Iron RElease
2014/5/20
The 15N composition of sediments has been used as a proxy for nitrate utilization in surface waters to assess the role of Southern Ocean export production in glacial/interglacial changes in atmospheri...
Iron availability, cellular iron quotas, and nitrogen fixation in Trichodesmium
Iron availability cellular iron quotas nitrogen fixation Trichodesmium
2014/6/9
Iron availability is suggested to be a primary factor limiting nitrogen fixation in the oceans. This hypothesis is principally based on cost-benefit analyses of iron quotas in the dominant nitrogen-fi...
Biogeochemical effects of iron availability on primary producers in a shallow marine carbonate environment
iron availability primary producers shallow marine carbonate environment
2014/6/9
We completed a synoptic survey of iron, phosphorus, and sulfur concentrations in shallow marine carbonate sediments from south Florida. Total extracted iron concentrations typically were <50 μmol g-1 ...
