Received on June 16, 1995; accepted on November 27, 1995 Experiments were performed in situ in shallow, subtropical Lake Okeechobee (Florida. USA) to quantify and compare the responses of phytoplanklon (in 20 I clear polycarbonate carboys) and periphyton (on nutrient-diffusing clay substrates) to additions of nitrogen and/or phosphorus. During early and late summer. 1994, both assemblages were nitrogen limited or co-limited by nitrogen and phosphorus, indicating the potential for competition between benthic and planktonic communities. During late summer, there was evidence that high phytoplankton biomass reduced light penetration through the water column and may have suppressed periphyton growth. The similar phytoplankton and periphyton taxonomic structures, both dominated by Lyngbya sp. and pennate diatoms, suggested that in shallow regions of this lake, resuspended meroplankton might account for a large portion of phytoplankton biomass. This phenomenon has been observed in other shallow, wind-driven Florida lakes.
