The Leibniz-IZW is an internationally renowned German research institute. It is part of the Forschungsverbund Berlin e.V. and a member of the Leibniz Association. Our goal is to understand the adaptability of wildlife in the context of global change and to contribute to the enhancement of the survival of viable wildlife populations. For this purpose, we investigate the diversity of life histories, the mechanisms of evolutionary adaptations and their limits, including diseases, as well as the interrelations of wildlife with their environment and people. We use expertise from biology and veterinary medicine in an interdisciplinary approach to conduct fundamental and applied research – from the molecular to the landscape level – in close dialogue with the public and stakeholders. Additionally, we are committed to unique and high-quality services for the scientific community.
+++ Current information on African swine fever: The Leibniz-IZW conducts research on the population dynamics, on models of disease outbreaks in wild boars and on the ecology and human-wildlife interaction in urban areas. African swine fever is a reportable disease in domestic swine and therefor is the purview of the respective federal state laboratories and the Friedrich-Loeffler-Institut (Federal Research Institute for Animal Health) FLI. +++
Over the past decades, the increased use of chemicals in many areas led to environmental pollution - of water, soil and also wildlife. In addition to plant protection substances and human and veterinary medical drugs, rodenticides have had toxic effects on wildlife. A new scientific investigation from scientists of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), the Julius Kühn Institute (JKI) and the German Environment Agency (Umweltbundesamt – UBA) demonstrate that these substances are widely found in liver tissues of birds of prey from Germany. Anticoagulant rodenticides, commonly used to kill rodents in agriculture and forestry, were frequently detected, particularly in birds of prey close to or in urban environments. Especially northern goshawks in the urban conurbation of Berlin and red kites in all habitats were frequently exposed to rodenticides. Evidence of rodenticides in white-tailed sea eagles demonstrated that scavengers occupying habitats more distant from human-modified landscapes are subjected to exposure as well. The results, which were supported by WWF Germany, are published in the scientific journal “Environmental Research”.
New technologies, new responsibilities: BioRescue develops ethical risk assessment for northern white rhino rescue programme
The BioRescue consortium develops and applies new technological approaches as a last straw for saving critically endangered species such as the northern white rhinoceros. Advanced Assisted Reproductive Technologies (aART) push the boundaries of what can be done to create new offspring. Consequently, new ethical questions regarding the application of these tools arise and need to be answered, and relevant animal welfare issues to be addressed. In order to ensure that the ethical risk assessment matches the technological breakthrough with aART, the BioRescue consortium developed and applies the “ETHAS” tool, an ethical self-assessment tool explicitly designed for assisting oocyte collections, in vitro fertilizations, embryo transfers and further procedures of the BioRescue consortium. ETHAS was developed under the leadership of Padua University and is described in detail in a new paper published in the scientific journal “Animals”.
The Senate of the Leibniz Association published its official statement on the regular evaluation of Leibniz-IZW on March 18, 2021. Leibniz institutions are evaluated by the Leibniz Senate every seven years at the latest. The evaluation focuses on an independent assessment of how the institution has developed in the intervening years, in terms of content and structure, as well as on the persuasiveness of its plans for the future. The Senate of the Leibniz Association adopts a statement on the basis of this evaluation, which usually contains recommendations for further funding of the institution. For Leibniz-IZW, the Senate of the Leibniz Association recommends that the Federal Government and the Länder continue joint funding of the institute.

The lists of the world’s endangered animals and plants are getting increasingly longer. But to stop this trend, important information is lacking. It is often difficult to find out exactly where individual species still occur and how their populations are developing. Specially trained detection dogs can be a valuable help in such cases, as a new scientific publication review shows. With the help of detection dogs the searched species can usually be found faster and more effectively than with other methods, report Dr Annegret Grimm-Seyfarth and Wiebke Harms from the Helmholtz Centre for Environmental Research (UFZ) and Dr Anne Berger from the Leibniz-Institute for Zoo and Wildlife Research (Leibniz-IZW) in the scientific journal "Methods in Ecology and Evolution".
Creating living embryos using artificial reproduction technologies provides a promising avenue to rescue mammalian species at risk of extinction. In order to grow in vitro a sufficient number of female gametes fit for fertilisation, scientists have to replicate the natural development of ovarian follicles right from the earliest – primordial – stage. Now, the first comprehensive analysis of gene expression (transcriptome) in early ovarian follicles of domestic cats gives an insight into the fundamental physiological mechanisms that could trigger follicle activation and growth in a species other than mice. The scientific work, performed by the scientists of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Berlin Center for Genomics in Biodiversity Research (BeGenDiv),is an essential stepping-stone towards supporting oocyte growth in vitro.
Koalas are facing multiple environmental and health issues which threaten their survival. Along with habitat loss - accelerated by last year’s devastating bush fires – domestic dog attacks and road accidents, they suffer from deadly chlamydial infections and extremely high frequency of cancer. An international team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now demonstrate that a retrovirus invading the koala germline explains the high frequency of koala cancer. The results are reported in the journal Nature Communications.
USAID Biodiversity Conservation Activity
In order to comply with the WWF "trafficking in persons" (TIP) policy Forschungsverbund Berlin e.V. (FVB) has developed this Anti-Human Trafficking Compliance Plan (AHTCP) within the framework of the USAID Biodiversity Conservation Activity.
For new species to evolve, conventional wisdom suggests that geographically isolated populations must exist that form separate reproductive communities. This isolation allows the genomes to slowly diverge and thus form new species. An international research team with participation of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the University of Haifa has now reconstructed the first reported case of localspeciation within a common gene pool in subterranean mole rats, a group of species which are rodents. Four out of five mole rat species of the superspecies Spalax ehrenbergi originated due to climate divergence over the past 1.5 million years, regionally across the country, and locally in the Upper Galilee through geological and soil microscale adaptive divergence in the last 228,000 years without chromosomal divergence in a common region. The latter local mechanism is called "sympatric speciation" and has now been demonstrated for the first time in a subterranean mammal in the team's paper published in the “Proceedings of the National Academy of Sciences of the United States of America”.
