The night is for sleeping? Not for all creatures: More than half of all animals are active during twilight or at night. The research team on light pollution from IGB, the StadtNatur association and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) invite you to participate in the "Living Night" photo competition to draw attention to this fascinating diversity and to raise awareness of the importance of protecting nocturnal landscapes. Photograph nocturnal and crepuscular species, find artificial light sources and win great prizes. All information at www.stadtwildtiere.de.

Masowy zakwit glonów można wykryć w Odrze za pomocą danych satelitarnych. 

In the Oder River, a massive algal bloom can be detected with satellite data. In close coordination with the IGB, satellite data from the European Copernicus satellite Sentinel 2 were processed.

The Oder is the last major river in Germany where fish and other animals can still migrate freely over long stretches. Since 2006, it has been the focus area for the reintroduction of the Baltic sturgeon. What is the fate of the sturgeon now?

Naturalne przyczyny tej zaistniałej katastrofy są mało prawdopodobne. Ostatnie badania wzmocniły podejrzenie, że w Odrze masowo rozwinęły się toksyczne glony słonawowodne.

A team with Jonathan Jeschke found that bat species with higher affinity to cities are characterised by relatively low frequencies and long durations of their echolocation calls, a small body size and flexibility in the choice of their daytime roost.

For the sturgeon species, the situation has deteriorated significantly since the last assessment of the IUCN in 2010, with the change being most dramatic in Europe and Asia.

Low-growing species such as stoneworts were last sighted in the Müggelsee over a century ago. Now, after 20 years of intensive mapping and diving surveys, not just one but three of these desirable species of underwater vegetation have been found.
