Influence of a freshwater
pulse
After 146 days of experimentation, a freshwater pulse was conducted on
conclusion of the first year of the experiment to determine if thermally
affected sites and control locations would respond differently to a
freshwater pulse after being subject to different temperature
treatments. Overall, the pulse significantly increased germination in
control and thermally affected seeds by 400 % and 180 %, respectively
(ANOVA; p < 0.001, Figure 6). There were no significant
interaction effects between pulse and seed location and thus the pulse
was not repeated for the second year.
