متن کاملMethanotrophy induces nitrogen fixation during peatland development.
Nitrogen (N) accumulation rates in peatland ecosystems indicate significant biological atmospheric N2 fixation associated with Sphagnum mosses. Here, we show that the linkage between methanotrophic carbon cycling and N2 fixation may constitute an important mechanism in the rapid accumulation of N during the primary succession of peatlands. In our experimental stable isotope enrichment study, pr...
متن کاملThe Late Archean Biospheric Explosion
biogenic platform carbonates [4]. By c.2.45 Ga oxygen levels had begun to rise in the Earth’s atmosphere setting the stage for the evolution of the modern biosphere. Here we focus on concretionary structures, which can act as sensitive barometers of biological activity, to provide us with potential insights into the expansion of this early biosphere prior to the first appearance of oxygen in th...
