Climate change will strongly affect many European freshwater fish species. This is particularly the case for species in the Mediterranean region, according to the latest findings of an international team of researchers.

153 researchers from 40 countries jointly investigated how climatic factors influence carbon cycling in flowing waters and their riparian zones.

Professor Rita Adrian is engaged in the long-term and climate impact research of lake ecosystems at IGB. The Intergovernmental Panel on Climate Change (IPCC) has selected her as a lead author of the IPCC Sixth Assessment Report (AR6), which is due to be released in 2021/22.

As the earth warms up, our bodies of water can release more methane and carbon dioxide. It is a vicious circle in which climate change itself intensifies. Researchers at IGB investigate the processes that lead to this release of greenhouse gases.

Lakes as the Müggelsee near Berlin are currently covered with an unusually thick carpet of algae. This algal bloom is primarily a result of the warm summer months, but there are also other reasons...

Scientists from  IGB have analysed long-term data to prove that decreasing nitrogen in Berlin’s Lake Müggelsee is the key to reducing algal blooms in summer.

Fish are an important element in the food web of lakes. This also applies to the experimental enclosures of the LakeLab. However, in this case, the number of fish must be controlled so that the results from the individual cylinders can be compared with each other. Because fish from the lake repeatedly jump into the enclosures, all fish must first be removed with nets from the cylinders before starting a new experiment. Today, 5 small perch were released into each enclosure for this year's LakeLab experiment.

As energy supplier and stimulus of the internal clock, light is of fundamental importance to plants and animals. This also applies to fish and microscopic organisms in lakes. Like other species, they have adapted to the day-night rhythm during evolution. But what happens if a lake is illuminated by artificial lighting at night, or if not enough light penetrates into the water during the day? These questions are examined during this year's summer experiment at the Lake Lab.
