Abstract |
Sixteen aquatic communities composed of persistent populations of guppies (Poecilia reticulata), amphipods (Gammarus fasciatus), snails (family Planorbidae), planaria (Dugesia sp.), and various microinvertebrates were established under laboratory conditions. Eight of these communities received low energy input with low habitat availability while the remaining eight communities had high habitat availability and received high energy input. At each level of input, guppy populations in two systems were exploited at either 0, 10, 20, or 40 percent of the population biomass each month. Macroinvertebrates were also sampled monthly for population counts and biomass measurements. After each system reached near steady-state conditions, 1 microgram/1 of dieldrin was introduced into one system of each treatment. These systems were allowed to reach new steady-state conditions. |
