The authors suggest that a census of biomass on Earth, i.e. Carbon makes up about half the dry weight of an ant. This means that the richer the species count of a given taxon, the larger biomass it probably has. The first globally comprehensive survey of the prokaryotic communities inhabiting the bathypelagic ocean using high-throughput sequencing of the 16S rRNA gene is reported, identifying the potential of the deep ocean as a reservoir of still unknown biological diversity with a higher degree of spatial complexity than hitherto considered.

It is revealed that animals can increase or decrease rates of biogeochemical processes, with a median change of 40% but ranging from 15 to 250% or more, and the key challenge, in light of these findings, is comprehensively accounting for spatially dynamic animal effects across landscapes.

Find something on Earth Online. The disproportionate impact of a human brain means that larger problems of larger populations can increasingly be solved better. Our analysis reveals that the global marine biomass pyramid contains more consumers than producers, thus increasing the scope of previous observations on inverse food pyramids. But evolution is a long game, and before long, the larger brains invented agriculture, livestock domestication, and industry. Analysis of prophage sequences deduced from prokaryotic genomes imply that lysogenic infection should be an important life strategy for viruses, making them more adaptable to the dynamic, and often extreme, deep biosphere environment.
