We examined the effects of the mud snails Hydrobia totteni and Ilyanassa obsoleta on microbial communities of sediments in microcosms. Varying density of Hydrobia, and the presence of Ilyanassa, exerted no effect on steady state bacterial standing stock. This is probably related to the rapid recovery rate of bacteria, despite efficient grazing....
