Insect canopy herbivory and frass deposition affect soil nutrient dynamics and export in oak mesocosms

Increased nitrogen (N) mobilization and export from terrestrial forest ecosystems following canopy herbivory have been well documented, though the mechanism behind the loss is not clear. Because carbon (C) and N dynamics are closely linked, herbivore activity may also affect C distribution. We initi...
