Global warming is increasing the surface temperatures of lakes worldwide – are species finding the temperatures they need to survive? Researchers led by IGB have quantified the long-term temperature changes in 139 lakes worldwide. 

Oxygen levels in freshwater lakes are declining rapidly – faster than in the oceans. Over the past forty years, for example, oxygen levels in the deep waters of temperate lakes have dropped by nearly 19 percent. 

In the Leibniz Research Alliance INFECTIONS'21 Hans-Peter Grossart will investigate the antibiotic resistances and species compositions of microorganisms in the freshwater ecosystems of Berlin.

From 5 to 12 April 2021 is the International Dark Sky Week. We want to draw attention to the issue of light pollution. Researchers from IGB are studying the effects of artificial light on insects.

Lakes in Arctic or boreal regions are usually covered by ice for several months. Such lakes are home to specialised algae (phytoplankton) that grow right under the ice and dominate the spring bloom. But what happens when the ice cover of these waters decreases as a result of climate change? A new model predicts abrupt changes.

Urban green spaces are increasingly suffering from persistently warm and dry periods. Even in temperate latitudes, precipitation amounts are decreasing while evaporation rates remain high, increasing irrigation needs. An IGB team has analysed the water consumption of vegetation in Berlin.

As a measure against the COVID-19 pandemic, public life was severely restricted for the first time in March 2020. But, did this also alter light pollution – the brightening of the night sky caused by too much artificial light?
