Six outdoor microcosms (2m{sup 3}) were used to determine copper sulfate effects on epibenthic and planktonic zooplankton community structure. Microcosms were treated three times with CuSO{sub 4} at 0, 50, 100, 200, 350, 550 {mu}g Cu/L, respectively. Zooplankton was sampled biweekly from July through October 1993. Epibenthic zooplankton was collected with an inverted funnel trap, whereas planktonic zooplankton was sampled with an integrated water column sampler. Samples were sieved through a 35 {mu}m mesh and organisms preserved with 1% Lugol`s solution and later identified to genus or species level. Both communities initially decreased in total abundance at high copper rates. However, recovery started shortly after the final Cu application. Species richness was lowest at high copper concentrations, particularly in the epi-benthic community. Epibenthic zooplankton diversity decreased at high copper rates, whereas planktonic zooplankton diversity did not. Epi-benthic zooplankton may be a sensitive indicator of chemical stress and therefore be used to assess the bioavailability of sediment-bound xenobiotics.
