Scientists at Eawag and Zurich University have synthesised for the first time the amounts of carbon transported between many different ecosystems. According to this global synthesis, spatial flows of carbon can be very large - and their significance has previously been underestimated.
The scene may be familiar from natural history documentaries - a migrating herd of wildebeest attempt to cross a raging river, with many of the creatures drowning in the process - but what viewers do not generally notice is that large amounts of carbon are thereby transported from a grassland to an aquatic ecosystem.
