Dangerous flight into the wind farm

Wind turbines attract bats. They seem to appear particularly appealing to female noctule bats in early summer. In a pilot study, researchers of the German Leibniz Institute for Zoo and Wildlife Research in Berlin noticed this when they tracked the flight paths of noctule bats,  Nyctalus noctula, using the latest GPS tracking devices . The bats managed to take even seasoned experts by surprise. ...

Maternal social status and sibling rivalry shape milk transfer in spotted hyenas

Females of low social status often have limited access to food resources. As a result, their offspring are nursed infrequently and may experience long fasting periods that can seriously compromise their growth and survival. In particular when they have to share their milk intake with a littermate, milk shortage can be very detrimental. Yet researchers from the Leibniz Institute for Zoo and Wildlife Research (IZW) and the former Max Planck Institute for Behavioral Physiology in Germany found that low-ranking spotted hyenas were able to compensate to some extent for their low nursing frequency...

Hippos in search of the last suitable water pools

Hippos in the Great Ruaha River in Tanzania face a profound loss of their habitat during the dry season. The river has much less water during this season than in previous decades because it is increasingly extracted for human use. As a consequence, the river dries up. Researchers from the German Leibniz Institute for Zoo and Wildlife Research (IZW) have now examined how this affects the distribution of hippos. Their results reveal extensive and long distance movements, as hippos search for vital daytime resting sites. The study has been published in the scientific journal “PLOS ONE”. ...

Welcome to the Leibniz Institute for Zoo and Wildlife Research!

Willkommen am Leibniz-Institut für Zoo- und Wildtierforschung (IZW)! Deutsche Version der IZW-Webseite.

The Leibniz Institute for Zoo and Wildlife Research (IZW) is an interdisciplinary research institute dedicated to developing the scientific basis for novel approaches to wildlife conservation.

In the current era of the Anthropocene, virtually all ecosystems in the world are subjected to man-made impacts. As yet, it is not possible to predict the response of wildlife to the ever-increasing global change. Why are some wildlife species threatened by anthropogenic change, while others persist or even thrive in modified, degenerated or novel habitats?

To answer this and related questions, the IZW conducts basic and applied research across different scientific disciplines. We study the diversity of life histories and evolutionary adaptations and their limits, including diseases, of free-ranging and captive wildlife species, and their interactions with people and their environment in Germany, Europe and worldwide.

The IZW is a member of the Leibniz Association and the Forschungsverbund Berlin e.V.
