Which fish species live in the Lake Müggelsee, how many of them are there, and how big do they get? These were the questions investigated by some 20 IGB employees between 8 and 10 October.

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.

Today 97 young scientists from across Europe start studying the society’s perception of ecosystem services provided by urban ponds, as well their ecological status.

Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Artificial lighting at night could be another reason for declining insect populations.

11 scientists and 300 kilometers of river: impressions of three weeks of sampling in the entire river network of the Vjosa in Albania.

Pesticides can cause big problems in ecosystems. That is the result of a new discussion paper of German National Academy of Sciences Leopoldina, in which effects of pesticides and options for action are explained based on recent scientific results.

Diversity is the key: IGB researchers have demonstrated experimentally that genetic diversity makes populations more resistant to disease.

The book and the website hi-knowledge.org present a new approach to synthesise heterogeneous data and information – here  applied to major hypotheses in the field of invasion biology.
