Novel applications of carbon isotopes in atmospheric CO₂: what can atmospheric measurements teach us about processes in the biosphere? [PDF]

Biogeosciences, 2011
Conventionally, measurements of carbon isotopes in atmospheric CO2 (δ13CO2) have been used to partition fluxes between terrestrial and ocean carbon pools.

Rising vapor‐pressure deficit increases nitrogen fixation in a legume crop

New Phytologist, 2023
Summary Atmospheric vapor‐pressure deficit (VPD) is increasing in many regions and has a large impact on plant productivity. A VPD increase leads to raising transpiration rate (TR) and soil‐water demand, risking productivity penalties. Like water, nitrogen is critical to productivity, but the effect of VPD on legume nitrogen fixation is undocumented.

Mucilage Polysaccharide Composition and Exudation in Maize From Contrasting Climatic Regions

Frontiers in Plant Science, 2020
Mucilage, a gelatinous substance comprising mostly polysaccharides, is exuded by maize nodal and underground root tips. Although mucilage provides several benefits for rhizosphere functions, studies on the variation in mucilage amounts and its ...

Sap flow of pecan trees in a US Southeastern orchard

Frontiers in Agronomy
Sap flow methods are widely used to estimate water use through transpiration in orchards. This study reports for the first time on pecan tree sap flow properties observed in a micro-irrigated orchard in the southeastern US in 2022 and 2023.
