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.

A new study suggests that humans are putting pressure on the population of these big cats in the Germany-Czech Republic-Austria border area.

In water-limited landscapes sick animals can have increased contact with healthy individuals, which can facilitate disease transmission. Scientists from the German Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) present these findings in the British Ecological Society journal Functional Ecology.

Quang Nam – 21^st May, 2018 - In November 2017 - under a biodiversity monitoring and assessment activity supported by the US Agency for International Development (USAID) - scientists and conservationists of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and WWF-Vietnam captured photographs of one of the rarest and most threatened mammal species of Southeast Asia, the large-antlered muntjac (Muntiacus vuquangensis), in Quang Nam province, central Vietnam. Prior to this milestone, this species had only been camera trapped in three protected areas in all of Vietnam since the year 2000. The new records from Quang Nam - which include photographs of both a male and a female - provide new hope for the continued survival of a species that is on the brink of extinction.

The transition to modernity – largely driven by the Industrial Revolution – provided us with easier access to food and clean water, with antibiotics, vaccines, and modern medicine. Yet modernity did not just bring fewer infectious diseases and longer life: it also created an environment radically different from the one we evolved in. Genes helpful in our evolutionary past may now predispose us to chronic disease – such as cardiovascular diseases and cancer – in old ages. In a paper published in the journal Nature Review Genetics an international team of five scientists collate the evidence for this mismatch between past evolutionary adaptation and our modern lives. They also ask whether natural selection linked to modernization might reduce globally the burden of some chronic diseases.

Numerous bat species hunt and migrate at great altitudes. Yet the open sky had, until recently, not been on the radar of conservation scientists as a habitat relevant to a large variety of species. Christian Voigt and colleagues from the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin have collated the current scientific knowledge on potential hazards to one group of animals flying at high altitudes, bats. In their recent article published in BioScience the authors synthesise threats facing bats in troposphere and provide recommendations for potential protective measures to ensure persistence of bats and other high-flying animals.

Przewalski’s horses were thought to be the last wild species of horse. A recent international study led by Professor Ludovic Orlando, involving the Leibniz Institute for Zoo and Wildlife Research (IZW), has upended that theory. The study, published in the journal “Science“, changes our point of view about domestic horse origins. Based on their archaeological and genetic investigations, the researchers were able to prove that Przewalski’s horse is descended from once-domesticated stock. Some of the horses from the domesticated herds escaped and became the ancestors of all present-day Przewalski’s horse populations. A second horse species existing at that time replaced Przewalski’s horses as domestic horses, establishing the lineage from which all modern domestic horses descend.

Female leopards have a much wider spectrum of prey species than males.
