Range-wide study on cheetah male spatial ...

Human-wildlife conflicts are common across the globe. In Namibia, cheetahs roam freely on privately owned farmland and occasionally prey on cattle calves. Drawing on GPS data obtained and analyzed in close collaboration with farmers, the CRP unraveled the spatial sytem of cheetah society and identified communication hubs as hotspots of cheetah activity and farmer-cheetah conflict. In a new range-wide study we aim to understand these patterns in a wider context across the range - and potentially upscale a successful conservation solution

First reported case of anthrax in wildlife in ...

Anthrax is an infectious bacterial disease endemic in some parts of Africa. It affects people, livestock as well as wildlife. Using GPS telemetry data, a team of scientists from the Cheetah Research Project of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) reconstructed a special case of anthrax infection in Namibia: Three free-ranging cheetahs in the Namib Desert died within 24 hours after feeding on a mountain zebra that tested positive for the disease. The zebra is the first described case of a wild animal infected with anthrax in this arid region. The case also shows that there might be previously unknown risks to cheetah populations in the desert. It is described in detail in the scientific journal “Frontiers in Veterinary Science”.

New video: science in a real-world laboratory

Human-wildlife conflicts are complex and require scientific facts as well as trustful collaboration and communication among all the stakeholders involved. At the IZW, the integration of stakeholders into the research process is an important strategy not only to improve the societal relevance of the scientific results, but also to break down barriers between science and society in terms practically applying these newly gained insights. In a new video the CRP and the Leibniz-IZW explain in detail why we think a new quality of our science-to-society interface is necessary and how we use the real-world lab concept in our cheetah research.

Kickstarting the trapping „season“ 2021

Capturing cheetahs with cage traps is one of the spines of the Cheetah Research Project. For several research questions addressed in the CRP, long-term data and information obtained from free-ranging cheetahs in the core study area are essential. Theoretically, this is a task that can be carried out at any time of the year - still, there are high-times of trappings and quieter times. Are there “trapping seasons” and if so, for what reasons? Here we explore the rationale behind the first concentrated trapping campaign of the year 2021.

Moving forward with cheetah research and ...

In early 2021 our team joined forces with data visualization expert Cédric Scherer vom the Leibniz-IZW to create a map from our recent PNAS study. The intent was to illustrate the key findings of the paper and to submit the map to the MoveMapCompetition from the Special Interest Group “Movement Ecology” of the British Ecological Society. We are very happy for the support of all the voters who made us win the ‘pretty map’ category and runner-up for the RMaps category. In a blog post for the BES’ Journal of Animal Ecology website we wrote about the creation of the map and the research behind it!

Scientists identify hotspots of cheetah activity as a key to solving the cheetah-farmer conflict in Namibia

Rural central Namibia is one of the most important strongholds of the declining global cheetah population. Here, the rarest large African cat lives on privately owned farmland. A traditional conflict poses a threat to them, as they occasionally prey on cattle calves and are therefore rarely welcomed on the farms. New insights into the cheetah’s spatial behaviour provide a viable solution to this human-wildlife conflict: In the core areas of male cheetah territories all local males and females frequently meet to exchange information. This results in hotspots of cheetah activity in these “communication hubs” and in substantially less activity in the vast areas between the core areas of the territories. Implementing this knowledge and moving their breeding herds with young calves out of these hotspots, farmers were able to reduce livestock losses by more than 80 percent. These insights are the result of a close and trusting cooperation between scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and farmers in central Namibia. They are published in the scientific journal “Proceedings of the National Academy of Sciences of the United States of America”.

Early first pregnancy is the key to successful reproduction of cheetahs in zoos

Early first pregnancy is the key to successful reproduction of cheetahs in zoos

Cheetah experts in many zoos around the world are at a loss. Despite all their efforts, these cats often do not reproduce in the desired manner. Researchers from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), together with colleagues from the Allwetterzoo Münster, have now found a key to the issue: the age of the mothers at the first pregnancy is the decisive factor. In contrast to the wild, felines kept in zoos are often bred only years after they have reached sexual maturity. From the study results, the researchers derive recommendations for keeping cheetahs in zoological gardens. The study was published in the journal "Journal of Zoo and Aquarium Research".

Territory holders and floaters: two spatial tactics of male cheetahs

Scientists of the Leibniz Institute for Zoo and Wildlife Research (Leibniz IZW) in Berlin analysed the spatial behaviour of cheetahs. They showed that male cheetahs operate two space use tactics which are associated with different life-history stages. This long-term study on movement data of over 160 free-ranging cheetahs in Namibia has now been published in the scientific journal ECOSPHERE.

Cheetah populations are endangered – Red List status should be immediately upgraded

Cheetah populations are endangered – Red List status should be immediately upgraded

A comprehensive assessment of cheetah populations in southern Africa reveals the critical state of one of the planet’s most iconic big cats. An international group of scientists presents evidence that realistic population estimates of cheetah in southern Africa are lower than previously recognised and that their population decline support a call to list the cheetah as “Endangered” on the International Union for Conservation of Nature (IUCN) Red List. The study is published in the open-access journal PeerJ.
