Appendix C. Supplemental figures.

   FIG. C1. Time courses for mean total nitrogen (top row) and total phosphorus (second row) in the Control (open circles, thin line) and Pulse (filled squares, thick line) treatments for each Zooplankton treatment (columns) beginning in mid-July and continuing through the end of the experiment in year 1999. Transient dynamics early in mesocosm development are not shown. The solid filled line along the x-axis in each panel indicates the day on which the nutrient pulse was applied. Error bars are ± 1 SE. Note the changes in y-axis scales between years 1999 (this figure) and year 2000 (Fig. C2).

   FIG. C3. Time courses for mean edible chlorophyll a (mg/L) in control (open circles, thin line) vs. pulsed (filled squares, thick line) mesocosms in each zooplankton treatment in each year, beginning in mid-July. Notice the differences in y-axis scales between the No Added and +Zooplankton treatments and between years.
