Dark spots on the surface of Slovak lakes

Microscopic Organism Detected in Slovak Lakes

Laboratory analyses conducted prior to the seasonal changes have confirmed the presence of Stentor amethystinus, a unicellular organism, in the Vajnorska and Nova Košariská lakes, according to a report by slovenska.sk. This flagellate, commonly found in freshwater ponds and lakes, exhibits a symbiotic relationship with green algae. Stentor amethystinus benefits from the algae’s ability to acquire nutrients, while the algae receive protection within the organism’s structure.

Researchers at the Bratislava Institute of Public Health noted that this microorganism is sensitive to light and actively seeks out areas with increased illumination within the lakes. The organism is visible to the naked eye under suitable conditions. The presence of dense pigment granules and concentrated symbiotic green algae on the water surface can create noticeable dark spots.

These observations highlight the complex ecological dynamics occurring within these Slovak lakes. Further investigation into the organism’s behavior and role within the aquatic ecosystem is ongoing.
