The abundance, biomass, and distribution of ants on Earth | PNAS
WEBWe conservatively estimate total abundance of ground-dwelling ants at over 3 × 10 15 and estimate the number of all ants on Earth to be almost 20 × 10 15 individuals. The latter corresponds to a biomass of ∼12 megatons of dry carbon. This exceeds the combined biomass of wild birds and mammals and is equivalent to ∼20% of human biomass.
The number of tree species on Earth | PNAS
WEBHere, based on a ground-sourced global database, we estimate the number of tree species at biome, continental, and global scales. We estimated a global tree richness (≈73,300) that is ≈14% higher than numbers known today, with most undiscovered species being rare, continentally endemic, and tropical or subtropical.
Climate change, human impacts, and carbon sequestration in China
WEBThis special feature explores the impacts of climate change and human activities on the structure and functioning of ecosystems, with emphasis on quantifying the magnitude and distribution of carbon (C) pools and C sequestration in China’s terrestrial ecosystems. We also document how species diversity, species traits, and nitrogen (N) and ...
