New research project with University of Potsdam: Individual based ecology


Conventional ecology focuses rather on the population and not on the individual. We argue that individuals constitute a level of variation that is highly relevant for understanding ecological processes, including conservation ecology.

The batlab is part of the Department Evolutionary Ecology at the Leibniz-IZW ( We are contributing to the institute's mission by doing "Research for Wildlife Conservation".


The IZW batlab of PD Dr. Christian Voigt consists of about 20 people, including postdocs, PhD student, master students and scientific and technical staff. 


We are not only doing top-end research for the conservation of wildlife species, we also work hard to communicate our findings to relevant stakeholders and the general public.

Using miniaturized GPS units we tracked the movements of common noctule bats at the Northsea coastline in Germany. We observed bats to avoid wind turbines over distances of several kilometers, suggesting that bats loose hunting areas when wind turbines are established. If bats approached wind turbines, they did so more often when turbines were located near farmhouses, waterbodies and daytime roosts. Thus, we suggest to avoid erecting wind turbines in proximity to these landscape elements.

With the help of 200 citizen scientists, Daniel Lewanzik and team found four ways to turn cities bat-friendly: 1) switch off light, 2) plant parks, 3) create ponds, and 4) connect habitats. Check out the paper at

The book is a compilation of concept, review and original articles about the bat-wind energy conflict; a pressing green-green dilemma that is yet unsolved. Articles are in German, yet the summary and figure legends are bilingual (both German and English). All articles were rigorously evaluated in a peer-review system.

E-book on 'Bats in the Anthropocene: Conservation of bats in a changing world'

This e-book reviews the current knowledge on why many bats are threatened worldwide and how to protect bats in a rapidly changing world. Bats comprise more than 1.400 species, are relevant ecosystem service providers, yet many species are at risk. This book is a key publication for bat experts, conservationists and students.
