Figures & data
Figure 1. Study site location. Inset: location of Lake Macatawa, MI. Blow up: Lake Macatawa showing connection to Lake Michigan and location of study site in Pine Bay.
Figure 2. Algal response to nutrient treatments. Top: Phytoplankton growth at the end of incubation, in order from left to right (n = 3 per treatment): control; +P; +N; and + N+P. Bottom: NDS showing periphyton growth at the end of incubation.
Figure 3. Periphyton Chl-a concentrations from the NDS at the end of the experimental incubation. Negative sign after the N treatment P-value indicates a (nonsignificant) decline relative to the control.
Figure 4. Change (final minus initial) in phytoplankton Chl-a concentrations over the experimental incubation period. Negative sign after the N treatment P-value indicates a (nonsignificant) decline relative to the control.
Figure 5. Microcystin concentration at the beginning (initial) and end (final) of the phytoplankton incubations.
