Current press releases

In a special issue of the leading scientific journal “Nature” and companion papers simultaneously published in other scientific journals, the Vertebrate Genomes Project (VGP) today announced 16 high quality, near error-free, and near complete vertebrate reference genome assemblies for species across all taxa with backbones (mammals, amphibians, birds, reptiles and fishes). This remarkable step towards a new quality and scale in genome sequencing of biological diversity – the largest genome in the project was 5 gigabases in size ­– will enable novel discoveries from life’s diversity. It was made possible by a decade-long collaboration among scientists all across the globe. The Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Berlin Center for Genomics in Biodiversity Research (BeGenDiv) contributed to this community effort by assisting in the development of the assembly pipeline, training of bioinformatics students in reference genome assembly and with the assembly and evolutionary analysis of three genomes: the Linnaeus's two-toed sloth (Choloepus didactylus), the collared anteater (Tamandua tetradactyla) and the green sea turtle (Chelonia mydas). Further publications based on these genomes for the three species are in preparation

The international consortium of scientists and conservationists working towards preventing the extinction of the northern white rhino through advanced assisted reproduction technologies is pleased to announce that in March and April 2021, four additional northern white rhino embryos were produced. This is the most successful series of procedures – from oocyte collection in Kenya to in vitro fertilisation and cryopreservation in Italy – the team of Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), Safari Park Dvůr Králové, Kenya Wildlife Service, Ol Pejeta Conservancy and Avantea has ever conducted. Additionally, the team confirmed the successful sterilisation of the southern white rhino bull Owuan, which was conducted in December 2020. The bull will now be introduced to the Ol Pejeta southern white rhino females that have been identified as potential surrogate mothers for future northern white rhino offspring.

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”.
