Abstract
- The emergence of billions of periodical cicadas affects plant and animal communities profoundly, yet little is known about cicada impacts on soil carbon fluxes. We investigated the effects of Brood X cicadas (Magicicada septendecim, M. cassinii and M. septendeculain) on soil CO <subscript>2</subscript> fluxes (R <subscript>S</subscript> ) in three Indiana forests. We hypothesized R <subscript>S</subscript> would be sensitive to emergence hole density, with the greatest effects occurring in soils with the lowest ambient fluxes. In support of our hypothesis, R <subscript>S</subscript> increased with increasing hole density and greater effects were observed near AM-associating trees (which expressed lower ambient fluxes) than near EcM-associating trees. Additionally, R <subscript>S</subscript> from emergence holes increased the temperature sensitivity (Q <subscript>10</subscript> ) of R <subscript>S</subscript> by 13%, elevating the Q <subscript>10</subscript> of ecosystem respiration. Brood X cicadas increased annual R <subscript>S</subscript> by ca. 2.5%, translating to an additional 717 Gg of CO <subscript>2</subscript> across forested areas. As such, periodical cicadas can have substantial effects on soil processes and biogeochemistry.<br /> (© 2024 John Wiley & Sons Ltd.)
