Ulvaria obscura is a common marine algae, typically identified in algal blooms referred to as "Green Tides". [3] [4] The species is distinct in its ability to produce the neurotransmitter dopamine as a herbivore defense mechanism.
The green tides caused by the overgrowth of Ulva prolifera in the Yellow Sea of China have been occurring every summer since 2007. The green tide is a major environmental concern that involves the impacts from natural, anthropogenic, physicochemical and algae factors along with the warming of local water.

Ulva species have been reported as a dominant species leading to blooms of green macroalgae often referred to as “green tides.” These green tides and marine fouling are attributed to their thallus morphological characteristics, fast growth rates in eutrophic ecosystems, and rapid uptake and assimilation of nutrients.

Sri Lanka is pockmarked with many irrigation dams, with its water resource distributed across nearly the entirety of the island for agricultural purposes via artificial canals and streams. Utilization of hydro resources for agricultural production dates back to the pre-Colonial era , with the current crop production now largely dependent on ...
Sri Lanka's current water management plan seeks to preserve the ecosystem and cultural benefits of the system while making large-scale investments in drinking water systems, sewage treatment plants, and commercial-industrial water infrastructure. [24]
Jaffna Lagoon is a shallow coastal stretch of water between the Jaffna and the Kilinochchi Districts in northern Sri Lanka. It is located between the longitudes of 79°54E and 80°20E, and the latitudes of 9°30N and 9°50N, and connected to Palk Bay through a channel to the west.
Southwestern Sri Lanka rivers and streams is a freshwater ecoregion in Sri Lanka. The ecoregion is listed in Global 200, a list of ecoregions compiled by the World Wide Fund for Nature for conservation priorities. [1] The extensive network of rivers and streams of Sri Lanka drains a total of 103 distinct natural river basins. [2]
