“…Vegetative reproduction is also important because populations are usually maintained by this method rather than by seed production. The environmental ranges of living adults and establishing seedlings have been emphasized because the range determines species distribution and abundance in vegetation (Grubb 1977;Grime 2006;Jeong and Kim 2017). Grubb (1977) stated that the environmental gradient affecting seed dispersal, germination, and seedling survival is the regeneration niche, while the environmental gradient affecting adult survival is the habitat niche.…”

Background: To reveal establishment strategy of Sparganium erectum, we tried to find realized niche of adults through field survey and effects of water level on the establishment process through mesocosm experiments. Results: In the field survey, the height and coverage of community living in deeper water were greater than those of community living in shallow water. There was no statistically significant difference (p > 0.05) in the means of water and soil properties between the two communities. In mesocosm experiments, we found no correlation between water levels and germination rates, but S. erectum seedlings have characteristics of post germination seedling buoyancy when S. erectum seeds germinated in inundation conditions. Shoot height, total leaf length, and survival rates of sinking seedlings in shallow water levels at −5, 0, and 5 cm were higher than those in deeper water levels at 10 and 20 cm. Floating seedlings established in water levels of 3 and 6 cm only. The seedlings could live up to 6 weeks in floating state but died if they were unable to establish. Conclusions: The water level around adult S. erectum communities in the field were different from the water level at which S. erectum seedlings can survive in the mesocosm experiments. The findings provided not only understanding of S. erectum habitat characteristics but also evidence to connect historical links between the early seedlings stage and adult habitat conditions. We suggested the logical establishment strategy of S. erectum based on the data.

This study sought to evaluate the mechanism of cellular injury caused by ferrous sulfate (FeSO4) and the protective effects of Parnassia palustris L. (PP) extract against FeSO4-induced cytotoxicity of cultured C6 glioma cells. FeSO4 is known to cause neurotoxicity and induce Parkinson's disease. The antioxidative effects of PP, such as superoxide dismutase (SOD)-like and superoxide anion-radical (SAR)-scavenging activities, as well as effects on cell viability, were studied. FeSO4 significantly decreased cell viability in a dose-dependent manner and the XTT50 value, the concentration of FeSO4 which reduced the cell viability by half, was measured at 63.3 μM in these cultures. FeSO4 was estimated to be highly cytotoxic by the Borenfreund and Puerner toxicity criteria. Quercetin, an antioxidant, significantly improved cell viability, damaged by FeSO4-induced cytotoxicity. While evaluating the protective effects of the PP extract on FeSO4-induced cytotoxicity, it was observed that the extract significantly increased cell viability compared to the FeSO4-treated group. Also, the PP extract showed superoxide dismutase (SOD)-like and superoxide anion radical (SAR)-scavenging activities. Based on these findings, it can be concluded that FeSO4 induced oxidative stress-related cytotoxicity, and the PP extract effectively protected against this cytotoxicity via its antioxidative effects. In conclusion, natural antioxidant sources such as PP may be agents useful for preventing oxidative stress-related cytotoxicity induced by heavy metal compounds such as the FeSO4, a known Parkinsonism inducer.
