Belowground carbon dynamics: root and rhizomorph respiration!

Belowground carbon dynamics: root and rhizomorph respiration!

Plants use their fine roots and rhizomorphs for transporting nutrients and water at the soil-root interface. Rhizomorphs are strand-like entities made of fungal hyphae that grow on fine roots of plants. Together, the fine roots and rhizomorphs account for a large percentage of annual net primary productivity, however the mystery lies behind their respiration processes. […]

Cold desert biological soil crust community influences soil CO2 exchange

Cold desert biological soil crust community influences soil CO<sub>2</sub0> exchange

Cold deserts, like the Colorado Plateau, US are the understudied relatives of warm deserts (eg. Sonora desert, US) with respect to their carbon cycling dynamics. Most of the rain pulse events measured in the Canyonlands region (Colorado Plateau) were smaller than 5 mm. The biological soil crust (biocrusts) are an important community in these deserts, […]

From roots to shoots: the previously untapped CO2 transport system

From roots to shoots: the previously untapped CO<sub>2</sub> transport system

Forests represent the majority of terrestrial primary productivity, and therefore play an important role in global carbon budgets, however not much is known about internal carbon dioxide (CO2) efflux, from the tree roots through the xylem to the foliage. Researchers in Georgia (US) studied an experimental Populus deltoides plantation to determine how much CO2 is […]
