摘要

Riparian plant leaves falling into estuaries can represent an important source of carbon available to aquatic food webs (SIN- SABAUGH & FINDLAY 1995, HELLINGS et al. 1999). Since microbial consumers ensure rapid decomposition of submerged leaves in large rivers (BALDY et al. 1995), bacteria may play an important role in the transformation of leaf litter in estuary ecosystems in which a major part of the trophic activity passes through bacteria (McLUSKY 1989). In addition, carbon and nutrients derived from leaves could be used by planktonic organisms such as protists (through bacteria consumption) and primary producers, respectively. The present study aimed at assessing the decay rate of wil-low (Salix triandra) leaves in the Schelde estuary (Belgium). In addition, we tested the idea that decomposing leaves stimu-late the productivity of heterotrophic bacteria as well as plank-tonic organisms in estuaries.
