using nitrate N and O isotopes to characterize the relative impacts of regeneration, assimilation, and denitrification on its supply is an important tool11,12,13. Ammonium is completely consumed in many ecosystems, but where isotope effects are permitted to be expressed (e.g., anoxic sediments an...
NITROGEN PROCESSES IN CULTIVATED PEAT SOIL - USE OF STABLE NITROGEN ISOTOPES TO DETERMINE FACTORS CONTROLLING DENITRIFICATION AND DNRA AFTER SLUDGE APPLICATION... AK Sovik,PT Morkved,B Klove - International Peat Congress 被引量: 0发表: 2004年 Removal of nitrogen in different wetland filter material...
To determine the dominant processes controlling nitrogen (N) dynamics in soils and increase insights into soil N cycling from nitrogen isotope (δ15N) data, patterns of15N enrichment in soil profiles were compiled from studies on tropical, temperate, and boreal systems. The maximum15N enrichment bet...
Plants sustain intimate relationships with diverse microbes. It is well-recognized that these plant-associated microbiota shape individual performance and fitness of host plants, but much remains to be explored regarding how they exert their function and
Using Carbon and Nitrogen Stable Isotopes to Distinguish the Locations of Feather Growth in Osprey (Pandion haliaetus) Use of flow cytometry and stable isotope analysis to determine phytoplankton uptake of wastewater derived ammonium in a nutrient-rich river ...
The average value of the ratio of stable nitrogen isotopes (δ15N) in the hair of the participants is 10.11‰. No differences have been established between the ratio of stable nitrogen isotopes (δ15N) in the hair of residents of the industrial city (10.00‰) and the protected area (10.19...
Nitrogen isotopes are widely used to study the trophic position of animals in modern food webs; however, their application in the fossil record is severely limited by degradation of organic material during fossilization. In this study, we show that the nitrogen isotope composition of organic matter...
