Lakes are crucial for biodiversity 🌍 #DYK Lake Ohrid, a European biodiversity hotspot, hosts unique species but faces threats from human activity? .—@ipbes.net #GlobalAssessment🧪 On #WorldLakeDay, let’s highlight the value of lakes, their sustainable management & the ecosystems they support.
Landscape photograph of Lake Ohrid, showing a vast expanse of deep blue rippling water in the foreground. The lake stretches to distant mountains that form the horizon line. Snow-capped peaks are visible on the higher mountain ranges. Under a bright blue sky, scattered white clouds create a serene atmosphere. The shoreline visible in the distance shows green forested areas and some buildings nestled along the coast. The water's surface has a gentle wave pattern, creating a textured appearance across the lake.

Unexpected survival strategies of plankton in alpine lakes have global relevance
Alpine lakes are among the most harsh aquatic environments on Earth. Located at high elevation, they are exposed to intense ultraviolet radiation (UVR), wide temperature and light fluctuations, and low nutrient availability.

Lago Nero (black lake) di Cornisello at 2240 m was rather green when we sampled it. An algal bloom!! This meant changing filters every few minutes. That night, our faces were of similar color (stomach bug) and we skipped the last lake. #CAPSOLUTION @mpimarinemicrobio.bsky.social @erc.europa.eu
Lago Nero, one of the more accessible mountain lakes on our tour.Impressive backdrop, but we had little time to admire it.Millions of microscopic algae turned the waters green.What species will it be once we analyze the filters in the lab?
