“…Soil CO 2 fluxes tended to be higher and increase more rapidly in response to increased temperature when W L col was below the wetland soil surface, whereas soil CH 4 fluxes tended to be higher and increase more rapidly in response to increased temperature when W L col was at or above the wetland soil surface. The magnitude of observed soil CO 2 and CH 4 fluxes from depressional black ash wetlands was similar to fluxes observed in wetlands under field and laboratory conditions [15,[61][62][63].…”

The rapid and extensive expansion of emerald ash borer (EAB) in North America since 2002 may eliminate most existing ash stands, likely affecting critical ecosystem services associated with water and carbon cycling. To our knowledge, no studies have evaluated the coupled response of black ash (Fraxinus nigra Marsh.) wetland water tables, soil temperatures, and soil gas fluxes to an EAB infestation. Water table position, soil temperature, and soil CO 2 and CH 4 fluxes were monitored in nine depressional headwater black ash wetlands in northern Michigan. An EAB disturbance was simulated by girdling (girdle) or felling (ash-cut) all black ash trees with diameters greater than 2.5 cm within treated wetlands (n = 3 per treatment). Soil gas fluxes were sensitive to water table position, temperature, and disturbance. Soil CO 2 fluxes were significantly higher, and high soil CH 4 fluxes occurred more frequently in disturbed sites. Soil CH 4 fluxes in ash-cut were marginally significantly higher than girdle during post-treatment, yet both were similar to control sites. The strong connection between depressional black ash wetland study sites and groundwater likely buffered the magnitude of disturbance-related impact on water tables and carbon cycling.

“…Many studies have been carried out in wetlands to explore how different ecosystem components contribute to overall wetland GHG release. Different components which contribute to overall wetland gas release include coarse woody debris, tree stems, respiring plants, and soils (Noh et al 2018;Maier et al 2011;Bubier et al 1995). Of these components, a heavy focus is often put on soil gas fluxes due to their function as an immense terrestrial carbon pool (Oertel et al 2016).…”
