Integrative concepts of the biosphere, ecosystem, biogeocenosis and, recently, Earth's
critical zone embrace scientific disciplines that link matter, energy and organisms in a …

Soil inorganic carbon (SIC) is the largest pool (≈ 950 Pg of soil carbonate+ 1404 Pg of
bicarbonate in groundwater; ie, 1 Pg= 10 15 g= 1 gigaton) of the global carbon cycle at a …

Afforestation, the conversion of non‐forested lands to forest plantations, can sequester

Grassland to forest conversions currently affect some of the world's most productive regions
and have the potential to modify many soil properties. We used afforestation of native …

Within highly fragmented forest landscapes, the flux of matter, energy and species from the
landscape matrix into the forest fragment interior is an important ecological phenomenon …

To meet economic and environmental demands for about 10 billion people by the mid‐21st
