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

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.
Ecological memory stored in a landscape can help an ecosystem recover from disturbances like fire and outbreaks of disease. But what happens when climate warming disrupts that process? How long before ecological memories stored in Read more…
