Biological nitrogen fixation supplies the largest quantity of new, natural nitrogen to terrestrial
ecosystems, but little is known about its function and controls in tropical forests. Recent work …

Molybdenum (Mo) is a key cofactor in enzymes used for nitrogen (N) fixation and nitrate
reduction, and the low availability of Mo can constrain N inputs, affecting ecosystem …

Iron (Fe), molybdenum (Mo), and vanadium (V) are the main components of the three known
biological nitrogenases, which constrain nitrogen fixation and affect ecosystem productivity …

The traditional view holds that the global distribution of biological nitrogen fixation (BNF) in
terrestrial ecosystems is primarily affected by climate, associating certain warm, wet low …

Biological nitrogen fixation (BNF) by canonical molybdenum and complementary vanadium
and iron-only nitrogenase isoforms is the primary natural source of newly fixed nitrogen …

Tropical cloud forests are characterized by abundant and biodiverse mosses which grow
epiphytically as well as on the ground. Nitrogen (N)-fixing cyanobacteria live in association …

Abstract Background and Aims Free living, non-symbiotic nitrogen-fixing bacteria
(diazotrophs) that inhabit plant rhizosphere substantially contribute to nitrogen input in forest …

[目的] 探究不同生长季杉木, 桉树, 马尾松人工林不同生态系统组分非共生固氮量空间分布变化
与含量差异.[方法] 利用普通克里金插值分析, 方差分析和相关性分析方法, 以广西高峰林场杉木 …

In tropical forests, free‐living Biological nitrogen (N) fixation (BNF) in soil and litter tends to
decrease when substrate N concentrations increase, whereas increasing phosphorus (P) …

Nitrogenase is the only natural enzyme capable of supplying new nitrogen (N) to the
biosphere. It converts inert atmospheric N 2 into bioavailable NH 3 using a metal cofactor …
