AbstractThe effect of dispersed and undispersed South Louisiana crude oil on the growth ofSpartina alternifloraand associated meiofaunal communities was investigated in a replicated experiment conducted in a uniform Louisiana salt marsh.

Neither crude oil nor oil plus dispersant had any inhibitory or stimulatory effect on the growth ofS. alternifloraor the meiofaunal communities, including the meiobent
