Belowground food webs in a changing climate
Amidst a network of tunnels and pores, soil organisms recycle carbon and nutrients. They
mix plant litter and detritus, causing changes in soil structure that can ultimately influence the
amount of water and oxygen available for plant roots. They are also eaten by aboveground
predators, providing direct connections between below-and aboveground food webs. Root
herbivory is very difficult to quantify, but likely just as important as leaf herbivory.
