Almost half of the total organic carbon (C) in terrestrial ecosystems is stored in forest soils.
By altering rates of input or release of C from soils, forest management activities can …

Nitrogen (N) and phosphorus (P) limitation constrains the magnitude of terrestrial carbon
uptake in response to elevated carbon dioxide and climate change. However, global maps …

The identity of the dominant root-associated microbial symbionts in a forest determines the
ability of trees to access limiting nutrients from atmospheric or soil pools,, sequester carbon …

Vegetation processes are fundamentally limited by nutrient and water availability, the uptake
of which is mediated by plant roots in terrestrial ecosystems. While tropical forests play a …

Nitrogen limits primary production in almost every biome on Earth,. Symbiotic nitrogen
fixation, conducted by certain angiosperms and their endosymbiotic bacteria, is the largest …

Symbiotic nitrogen fixation (SNF) is a key ecological process whose impact depends on the
strategy of SNF regulation—the degree to which rates of SNF change in response to …

The connection between soil nitrogen availability, leaf nitrogen, and photosynthetic capacity
is not perfectly understood. Because these three components tend to be positively related …

A fundamental biogeochemical paradox is that nitrogen‐rich tropical forests contain
abundant nitrogen‐fixing trees, which support a globally significant tropical carbon sink. One …

Biological nitrogen fixation (BNF) by microorganisms associated with cryptogamic covers,
such as cyanolichens and bryophytes, is a primary source of fixed nitrogen in pristine, high …

Legumes provide an essential service to ecosystems by capturing nitrogen from the
atmosphere and delivering it to the soil, where it may then be available to other plants …
