The Zoological Research Museum Alexander Koenig

is a research museum of the Leibniz Association

Our mission

Discovering and explaining biodiversity

We carry out species-related biodiversity research and ensure the transfer of knowledge to researchers and the general public.

Core stocks are our zoological collections of more than 5 million units. Our research focusses on performing an inventory of the zoological species diversity on earth.

The results of research and the collections are made accessible to the public with permanent and temporary exhibitions and using other methods for public education.

In recent years, it has become evident that bacteria contain various cytoskeletal proteins that are critical for their fitness and survival. These include homologs of actin, tubulin and intermediate fila­ment proteins as well as bacteria-specific factors, such as the bactofilins.Bactofilins are an atypical group of cytoskeletal proteins that share structural simililarity with prion pro­teins and assemble into stable polymeric structures without the need for nucleotide cofactors.

In some species, the synchronization of individual behavior can give rise to complex and coordinated group performances (e.g. flocking of birds, herding of quadrupeds, swarming of insects or shoaling of fish).Here, large numbers of individuals move aligned and with synchronized speeds, thus giving the impression of a single organism. These large-scale dynamic patterns emerge in a self-organized fashion, e.g., by simple interactions among participating individuals.
