Enhancement of benthic metabolism (O2 uptake or CO2 release) in sandy sediment inhabited by Nereis spp. and Arenicola marina. Values are given as percent difference between faunated and defaunated sediment (flux enhancement). The experimental conditions are indicated as: homog. = homogenized sediment in laboratory, intact = intact, but defaunated sediment in laboratory, in situ = in situ measurementa |
