Abstract
For the most part, photosynthetic pigments were largely affected by sun exposure and less by emersion stress. Shaded blades maintained higher concentrations of photosynthetic pigments compared to sun exposed thalli concurring with established research. Photosynthetic efficiency measurements indicated emersion and not sun exposure was the greater facilitator of photoinhibitory damage and ROS generation at PSII. The findings of this field study strengthen previous assertions that protection via elevated antioxidant metabolism and increased PSII repair are involved in providing relief from the acute environmental stresses in the intertidal zone.
