Current uptake of 15N –labeled ammonium and nitrate in flooded and non-flooded black spruce and tamarack seedlings.
Download2009
Macdonald, S. Ellen, Islam, M. Anisul
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....

First-principles calculations of equilibrium nitrogen isotope fractionations among aqueous ammonium, silicate minerals and salts
Download2021-03-15
Li, Yonghui, Li, Long, Wu, Zhongqing
Nitrogen isotopes are a robust tool to study geological nitrogen cycle between Earth’s reservoirs. However, the application of nitrogen isotope system to understanding geological processes has been limited by the lack of constraints on equilibrium isotope fractionation factors between mineral and...

Nitrogen isotope fractionations among gaseous and aqueous NH4+, NH3, N2, and metal-ammine complexes: Theoretical calculations and applications
Download2021-02-15
Li, Long, He, Yuyang, Zhang, Zhe, Liu, Yun
Ammonium (NH4+), ammonia (NH3) and N2 are key nitrogen species in geological nitrogen recycling. NH3 has also been proposed to play an important role in mobilizing base metals in the form of metal-ammine complexes in hydrothermal fluids. The nitrogen isotope fractionation factors among these...

Herein, a new methodology is developed to replicate functions, measures and stochastic processes onto a compact metric space. Each replica object is a weak or strong modification of the original object, so many results are easily established for the replica objects and then transferred back to...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...
