Old-growth forests remove carbon dioxide from the atmosphere

A study was conducted to estimate the soil organic carbon pool under Eucalyptus, Poplar, Shisham and Teak plantations in Haridwar and Dehra Dun, districts of Uttarakhand and Yamunanagar District of Haryana State.

Nutrients carried by the Amazon River into the Atlantic Ocean help absorb significant amounts of carbon dioxide (CO2) from the atmosphere, new research reveals. The nutrients fertilize a type of plankton that the researchers estimate to consume 27 million metric tons of CO2 annually.

Chemical analysis of hot springs in the Himalaya suggest that the carbon released from mountain forming regions may warm Earth.

Mangrove forests are highly productive but globally threatened coastal ecosystems, whose role in the carbon budget of the coastal zone has long been debated. Here we provide a comprehensive synthesis of the available data on carbon fluxes in mangrove ecosystems.

Long-term monitoring of distributed, multiple plots is the key to quantify macroecological patterns and changes. Here we examine the evidence for concerted changes in the structure, dynamics and composition of old-growth Amazonian forests in the late twentieth century. In the 1980s and 1990s, mature forests gained biomass and underwent accelerated growth and dynamics, all consistent with a widespread, long-acting stimulation of growth. Because growth on average exceeded mortality, intact Amazonian forests have been a carbon sink.
