↵a Volume measurements of burrows in tall- and short-form Spartina are from a prior study (30). Total burrow water mass is estimated from 2007 burrow enumerations and diameters, utilizing McCraith's volume estimates (31).

↵* , Juncus volume estimate based on the current study's burrow diameter measurements and McCraith's estimates of burrow lengths. Juncus total burrow water volume is based on enumerations of the current study. Average Vibrionaceae and V. parahaemolyticus numbers per square meter were calculated using average numbers of CFU ml

^{−1}, burrow volume, and burrow abundances. To calculate total numbers of cells transported, the North Inlet area Spartina estimate of 24 km^{2}was used (10). NA, not available.
