Aquatic Plant Diversity of Lakes in Somwarapete Taluk, Kodagu, Karnataka
Summary
Researchers documented 43 aquatic plant species across three lakes in Kodagu district, Karnataka, India over a one-year study period. Dominant families included Araceae and Hydrocharitaceae. This biodiversity survey provides a baseline for monitoring how pollution and land use changes affect freshwater ecosystems in this region.
The principal objective of the present research is to record data regarding the aquatic plants of Somwarapete taluk of Kodagu district. Three major lakes were selected for the study for a period of one year, i.e., June 2020–July 2021. A total of 43 species were recorded, belonging to 28 families and 41 genera. The most dominant families were found to be Araceae, Hydrocharitaceae, Asteraceae, and Amranthaceae. After initial identification, the plants were classified according to their habitats, life spans, and IUCN status. Jaccard’s index and Sorenson's index were used to learn about the similarity coefficient between the sample sites. We divided plants in accordance with their IUCN status and found them to be endangered, threatened, and under the category of least concern. The work was undertaken because no documented data is available for the aquatic macrophytes of Somwarapete taluk.

Diversity and relative abundance of aquatic insects of Dahaura Lake, Bahraich, U.P.
This ecological survey documented aquatic insect diversity and abundance in Dahaura Lake in India over a six-month period, finding 25 genera from multiple orders. Aquatic insects are bioindicators of water quality and could be used to assess the ecological impacts of microplastic contamination in freshwater ecosystems.
Diversity and distribution of seagrasses in Chilika Lagoon: Regional threats and management recommendations
Researchers surveyed seagrass diversity and spatial distribution across 57 sites in the Chilika Lagoon — Asia's largest brackish water lagoon — recording six species including Halophila ovalis, Halodule pinifolia, and Ruppia maritima, with the southern sector showing the highest species richness and density. The study identified key regional threats to seagrass meadows and provided management recommendations for this ecologically significant coastal lagoon system.
Heavy Metal Concentrations in Certain Edible Freshwater Fishes and Sediments from Kapila River in Mysore District, Karnataka
Researchers measured heavy metal concentrations in three freshwater fish species from the Kapila River in Karnataka, India. Levels of arsenic, lead, nickel, and other metals were found in fish tissues and sediments. Since heavy metals can accumulate in fish consumed by local populations, these findings raise food safety concerns for communities relying on this river.
