In the vast, open ocean with no place to hide, sardines group together for protection. When they cannot rely on speed to escape, the sardines’ best chance is to outmaneuver the predator altogether. However, predators also seek ways to find weak spots in the group’s defence.

The PONDERFUL project provides a large collection of open resources on how to foster ponds and pondscapes.

The website Hi Knowledge presents a new approach for combining heterogeneous data and information on biological invasions. It also provides innovative tools for finding knowledge quickly and easily.

A new study led by the University of British Columbia (UBC), with contributions from IGB, has revealed alarming results: climate change could lead to an increase in bacterial and fungal infections in cold-blooded animals such as corals, insects and fish. 

Cigarette butts do not belong in the environment. Yet they often end up there, especially near water bodies. A survey by IGB has shown that many of Berlin's waters contain considerable amounts of nicotine, which is also toxic to aquatic life. A new IGB study now shows that some organisms may benefit indirectly: toxic cyanobacteria. This is because cigarette butts in the water harm their parasites. The study was published in the journal Ecotoxicology and Environmental Safety.

DNA metabarcoding is a molecular analysis method that offers a promising solution for efficient insect monitoring. A study published in the journal Molecular Ecology Resources, to which researchers of IGB contributed, provides detailed guidelines for the large-scale application of this method, including estimates of the costs and time required.

When an endangered species succeeds in repopulating its former habitat, the immediate reaction is one of joy. In the long term, however, its spread is often associated with conflict. One example is the beaver, a keystone species. Other keystone species include the wolf and the bison. These are animals that have an extraordinary impact on the ecosystems in which they live. The reintroduction of such keystone species often restores important processes and ecosystem functions.

A study in Nature Communications has shown at the genetic level how bacteriophages can maintain an important metabolic pathway in infected aquatic bacteria – presumably in order to have enough energy for their own reproduction.
