Feeding ecology of benthic filter-feeders at Potter Cove, an Antarctic coastal ecosystem
A rich benthic filter-feeding community is present at Potter Cove, South Shetland, in spite of some usually unfavorable conditions affecting their feeding ecology, such as low phytoplankton production in summer and high sedimentation rates. However, organic material that could fuel the benthic syste...
