A considerable amount of sturgeon caviar sold in Bulgaria and Romania is mislabeled or even counterfeit. These findings were discovered by scientists from the German Leibniz Institute for Zoo and Wildlife Research (IZW) and the WWF Austria. The results of the market survey have just been published in the scientific journal “Journal of Applied Ichthyology”.

New scientific research could help to protect tigers (Panthera tigris) from extinction. The findings indicate that tigers should be classified as only two subspecies – up to now nine subspecies were previously recognized. This will have a significant impact on species conservation since management efforts and breeding programmes can now be organised in a simpler, more flexible and effective way. The results have been published in the scientific open access journal “Science Advances”.

Innovation in hormone research – A team of researchers from the Leibniz Institute of Zoo and Wildlife Research (IZW) and the University of Pretoria succeeded for the first-time in measuring metabolites of testosterone excreted in the faeces of spotted hyenas. This innovative non-invasive research method is essential to avoid disturbance of animals.

Bats in tropical regions are fertilizing trees with their excretions. An international team of scientists recently discovered that seeds of a tropical tree species, which regularly hosts bats in large hollows, contain nutrients from bat excreta. The study has now been published in the scientific journal “Biotropica”.

With their specialized diet of almost exclusively Eucalyptus leaves, do koalas require specialist microbes to help them digest their food? Scientists from the Leibniz Institute for Zoo and Wildlife Research (IZW) investigated the composition of bacterial communities in different digestion-associated organs but found no unusual or special microbial communities when they compared these with those of other mammals. The study also demonstrates that non-invasive samples such as faecal samples commonly used to assess the composition of microbial communities may not provide an accurate account of the host gut microbiome. The study has just been published in the scientific journal “Scientific Reports”.

The Leibniz Institute for Zoo & Wildlife Research (IZW) in Berlin, Germany, today inaugurates the world’s most advanced state-of-the art computer tomograph currently available in veterinary research. The new CT enables fascinating virtual insights into wildlife. It will be possible to display organ movements at a new level of spatial and temporal resolution, e.g. live heart beats.

The Leibniz Institute for Zoo and Wildlife Research (IZW) is cofounder of the Leibniz research alliance ‘INFECTIONS´21 – Transmission Control of Infections in the 21st Century’. The new Leibniz alliance investigates the control, prevention and combat of infectious diseases. Fourteen Leibniz institutions and three external partners are participating in this interdisciplinary project. The association is funded with a total volume of 600.000 EUR for four years.

Scientists discovered a new retrovirus “fossil” found in the common vampire bat which is homologous to retroviruses in rodents and primates. The results suggest the recent circulation of an active infectious retrovirus and cross-species transmission. The study has been published in the scientific journal “Journal of Virology”.

Numerous bats are killed by German wind turbines. The number of such turbines, already very high, is planned to be increased further. More than two-thirds of bats being killed by wind turbines on German ground are migrants on their way between summer and winter habitats. Due to its geographical location in Europe, Germany has consequently a central responsibility for the conservation of migratory bats.
