Nickel limitation of nitrogen fixation inTrichodesmium
Nickel limitation nitrogen fixation Trichodesmium
2014/4/2
I show that the growth ofTrichodesmium, the primary diazotrophic phytoplankton in tropical and subtropical oceans, can be limited by Ni availability in both trace metal–defined culture media and natur...
Advective transport of diazotrophs and importance of their nitrogen fixation on new and primary production in the western Pacific warm pool
Advective transport diazotrophs importance their nitrogen fixation new primary production in the western Pacific warm pool
2014/4/2
The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll concentrations in which new production is generally considered to be supported by upward fluxes of nitrate from the dee...
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation
Iron phosphorus nitrogen fixation
2014/4/2
We present a unified conceptual framework describing the competition between diazotrophs and non–
nitrogen-fixing marine plankton and their interaction with three essential nutrient elements: nitroge...
Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/4
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
The Mekong River plume fuels nitrogen fixation and determines phytoplankton species distribution in the South China Sea during low and high discharge season
The Mekong River plume fuels nitrogen fixation determines phytoplankton species distribution the South China Sea low and high discharge season
2014/4/17
The influence of the Mekong River (South China Sea) on N2 fixation and phytoplankton distribution was investigated during the lowest- and highest-discharge seasons (April 2007 and September 2008, resp...
Latitudinal distribution of diazotrophs and their nitrogen fixation in the tropical and subtropical western North Pacific
Latitudinal distribution diazotrophs nitrogen fixation the tropical subtropical western North Pacific
2014/4/18
Latitudinal distribution of diazotrophs and their nitrogen (N2) fixation activity were investigated in the western North Pacific in winter (Nov to Dec 2004) and summer (May to Jun 2005) along meridion...
Nitrogen fixation may not balance the nitrogen pool in lakes over timescales relevant to eutrophication management
Nitrogen fixation may not balance nitrogen pool in lakes over timescales relevant eutrophication management
2014/4/17
We explored multiyear linear trends in nutrient concentrations, nitrogen (N) : phosphorus (P) ratio, and phytoplankton biomass within the 37-yr, whole-ecosystem nutrient enrichment experiment in Lake ...
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 ...
Nitrogen-fixation strategies and Fe requirements in cyanobacteria
Nitrogen-fixation strategies Fe requirements
2014/4/22
Diazotrophic (nitrogen-fixing) cyanobacteria are important contributors of new nitrogen to oligotrophic
environments and greatly influence oceanic productivity. We investigated how iron availability ...
Nitrogen fixation along a north-south transect in the eastern Atlantic Ocean
Nitrogen fixation north-south transect eastern Atlantic Ocean
2014/4/22
Nitrogenase activity, indicative of N2 fixation, was measured in the surface waters along a north-south transect in the eastern Atlantic Ocean, from Texel (The Netherlands, 53°N) to Cape Town (South A...
Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean
Nitrogen fixation unicellular diazotrophic cyanobacteria temperate oligotrophic North Pacific Ocean
2014/4/22
N2 fixation has been understudied in marine environments outside of the subtropical and tropical oceans and where water temperatures are typically below 20-25°C. We identified nifH phylotypes and meas...
