Eleocharis parvula · Accepted scientific name

Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆

Eleocharis parvula is a delicate, carpeting aquatic plant frequently utilized in high-end aquascaping to create lush, green foregrounds. This species thrives in well-maintained tanks where it can spread its fine, needle-like leaves across the substrate. While it is prized for its aesthetic appeal, its growth can be sensitive to various environmental stressors. Research suggests that heavy metals, such as mercury, can significantly impact the physiological health and survival of aquatic flora. Understanding these chemical interactions is essential for maintaining a stable and healthy underwater ecosystem.

Biological Activities

Compounds

Conditions

Eleocharis parvula exhibits a notable resilience when exposed to elevated aqueous mercury levels. Research indicates that this species remains relatively unimpacted in terms of both net CO2 assimilation and long-term biomass production. While the plant accumulates significant mercury concentrations in its belowground tissues, its growth status remains stable compared to more sensitive species. Despite this ability to tolerate contamination, the level of mercury accumulation in its tissues is lower than that seen in other aquatic plants. Consequently, while it can withstand mercury exposure, it may not be the most optimal candidate for active phytoremediation efforts.
