| Changes of radioactivity in a natural C-14 labelled sediment were monitored over a 120-hour period in the presence and in the absence of the deposit-feeding bivalve Abra alba. In both cases, the sediment showed great instability during the first ten hours of the experiment. The consequences of this result on the experimental protocol used for the study of the interactions between natural sediments and deposit-feeders are discussed. In controls, the instability is produced by an initial decrease of radioactivity in the sediment, whereas in the presence of Abra alba, it corresponds to an initial increase of radioactivity. Analysis of previously published data suggests that such responses may result from the inhibition or the stimulation of the bacterial... |
