Influence of bottom water anoxia on nitrogen isotopic ratios and amino acid contributions of recent sediments from small eutrophic Lonar Lake, central India
nitrogen isotopic ratios Influence
2014/4/2
Lonar Lake is a eutrophic, saline soda lake with permanently anoxic deep water. The high pH and
deoxygenation result in very elevated d15N of suspended particulate matter (SPM) and sediments due to
...
Molybdenum–nitrogen co-limitation in freshwater and coastal heterocystouscyanobacteria
coastal heterocystous cyanobacteria
2014/4/16
Molybdenum (Mo) is essential for the biological assimilation of inorganic nitrogen (N). We compared Mo
requirements for N2
-fixation in two species of filamentous heterocystous cyanobacteria (HC) to...
Cross-basin comparison of phosphorus stress and nitrogen fixation in Trichodesmium
phosphorus stress nitrogen fixation
2014/4/17
We investigated the phosphorus (P) status and N2 fixation rates of Trichodesmium populations from the North
Pacific, western South Pacific, and western North Atlantic. Colonies of Trichodesmium were ...
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...
Sources of nitrogen used for denitrification and nitrous oxide formation in sediments of the hypernutrified Colne, the nutrified Humber, and the oligotrophic Conwy estuaries, United Kingdom
denitrifi cation nitrous oxide
2014/4/30
Rates of denitrification and nitrous oxide (N2
O) formation, and the sources of N2
and N2
O, were examined by
the isotope-pairing technique in three U.K. estuaries (Colne, Humber, Conwy), wh...
Seasonal bioavailability of dissolved organic carbon and nitrogen from pristine and polluted freshwater wetlands
Seasonal bioavailability pristine
2014/5/19
We examined the chemical composition and bioavailability of dissolved organic carbon (DOC) and nitrogen
(DON) from two pristine and two polluted cedar bog wetlands across three seasons. Pristine and ...
Recovery of Thalassiosira weissflogii from nitrogen and silicon starvation
nitrogen silicon starvation
2014/5/14
The ecological success of marine diatoms comes despite their unusual additional requirement for silicon, a nutrient
that often limits their growth in the ocean. There may be, however, some physiologi...
