Linking Soil CO2 Efflux to Individual Trees: Size-Dependent Variation and the Importance of the Birch Effect
Original language description
Soil CO2 efflux (F-CO2) is a major component of the terrestrial carbon (C) cycle but challenges in explaining local variability hamper efforts to link broad-scale fluxes to their biotic drivers. Trees are the dominant C source for forest soils, so linking tree properties to F-CO2 could open new avenues to study plant-soil feedbacks and facilitate scaling, furthermore, F-CO2 responds dynamically to meteorological conditions, complicating predictions of total F-CO2 and forest C balance. We tested for proximity effects of individual Acer saccharum Marsh. trees on F-CO2, comparing F-CO2 within 1 m of mature stems to background fluxes before and after an intense rainfall event. Wetting significantly increased background F-CO2 (6,4 +- 0,3 vs. 8,6 +- 0,6 s.e. mu mol CO2 m(-2) s(-1)), with a much larger enhancement near tree stems (6,3 +- 0,3 vs. 10,8 +- 0,4 mu mol CO2 m(-2) S-1). F-CO2 varied significantly among individual trees and post-rain values increased with tree diameter (with a slope of 0,058 mu mol
