Leibniz-IZW condemns Russia's attack on Ukraine
The Leibniz Institute for Zoo and Wildlife Research strongly condemns Russia's attack on Ukraine. The Leibniz-IZW employs Ukrainian scientists, is very concerned about our scientific colleagues in Ukraine and will support scientists in Ukraine to the best of our ability.
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. +++

Cheetahs need more space: Reintroduction in India must consider their spatial ecology
In autumn 2022 and winter 2023, a total of 20 cheetahs from Namibia and South Africa were introduced to Kuno National Park in India to establish a free-ranging population – for the first time since their extinction in India 70 years ago. Although the idea may be commendable, getting it right is not so easy. Scientists of the Cheetah Research Project of Leibniz-IZW in Namibia see shortcomings in the reintroduction plan: In southern Africa, cheetahs live in a stable socio-spatial system with widely spread territories and densities of less than one individual per 100 km². The plan for cheetahs in Kuno National Park assumes that the high prey density will sustain high cheetah densities, even though there is no evidence that high cheetah density depends on high prey density. As Kuno National Park is small, it is likely that the released animals will move far beyond the park's boundaries and cause conflicts with neighbouring villages, the team said in a letter in the scientific journal “Conservation Science and Practice”.

Hyenas die also in road accidents
Which factors influence the risk of fatal collisions between vehicles and spotted hyenas in the Serengeti? Findings from a long-term study over three decades
The Serengeti National Park in Tanzania is home to large populations of wildlife species, including spotted hyenas (Crocuta crocuta). While many human activities are prohibited in the national park, driving is allowed in and through the protected area. Using a 34-year long-term data set, a scientific team from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) analysed which factors significantly contributed to hyenas being run over and killed by vehicles. These were, firstly, the type of road, and secondly, the annual migration of the large ungulate herds in the Serengeti and the associated seasonal changes in the localisation of the prey animals of spotted hyenas. The findings provide new insights into which ecological and individual factors influence the risk of fatalities for carnivores in collisions with vehicles; they were published in the scientific journal Biological Conservation.
EU-funded PANDASIA project reduces risk of pandemics and enhances health literacy in Thailand and Europe
Emerging infectious diseases, which are caused by zoonotic pathogens such as viruses and bacteria are transmitted between animals and humans, pose an increasing threat to global health. Zoonoses occur primarily where wild animals and humans come into regular contact. Owing to its species diversity, human population density, and movement, Southeast Asia is considered as hotspot for the emergence of new zoonoses and subsequent pandemics. Climate change and loss of biodiversity accelerate the risk of new pandemics. The EU-funded, transdisciplinary scientific project PANDASIA investigates potential risks of new pandemics in Thailand and develops preventive measures. Findings will be used to enhance health literacy of different target groups and communities.

Computer tomography images reveal dinosaur bones in unopened bamboo corsets and transport crates
With the help of computer tomography images, Berlin scientists from the Museum für Naturkunde (MfN), the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Charité – university medicine of Berlin – reconstructed the contents of unopened expedition crates from the Tendaguru dinosaur site in Tanzania. The virtual preparation of the material in the bamboo corsets and transport crates revealed numerous dinosaur bones, mainly from the small gazelle dinosaur Dysalotosaurus lettowvorbecki, packed in hut clay lumps, in old tin cans or as whole collections of loose bones. With the help of these images, the team created a prioritisation list for the palaeontological preparation of this material. The images also provide a valuable testimony of this historic expedition and the performance of the Tanzanian excavation workers and porters in the colonial context.

With a little help – European Northern Bald Ibis population well on the way to self-sustainability
A recently published paper in the journal ORYX evaluates the success of the established and well-known European reintroduction project for the northern bald ibis (Geronticus eremita). Scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and from the Austrian company Waldrappteam Conservation and Research evaluated demographic data from almost 400 individuals over 12 years and modelled future scenarios. The population has good survival and reproduction rates and the modelling also showed positive future survival probabilities, even assuming irregular losses due to catastrophes. The reintroduced population therefore has a good chance of long-term survival, the team concludes.

Scientists unveil the highest quality map of sea turtles’ genomes – their future may lie in their evolutionary history
In a paper recently published in the scientific journal “Proceedings of the National Academy of Sciences”, an international team of scientists revealed an incredibly detailed genetic map of two species – green and leatherback sea turtles. This will, for the first time, elucidate the genetic foundations that have enabled the once land-dwelling turtles to thrive in oceans throughout the world. Around 100 million years ago, their ancestors turned to the oceans, eventually evolving into the sea turtles that we know today. Knowing the genetic background of this remarkable adaptation may prove crucial for their conservation in current times of rapid environmental change.
