(A) Sv as a function of depth for the acorn worm Schizocardium sp. with mean animal density of 500 m-2. (B) Burrow densities for populations of 100 m-2 (blue), 311 m-2 (red), 356 m-2 (black) and 800 m-2 (green). Lines are burrow densities from this study; symbols represent number of active burrows reported from X-radiography of mesocosm slabs.[32] Error bars represent ±1 standard deviation in burrow density.
