    COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance of ...
  • Comparative serum fatty acid profiles of captive and free-ranging cheetahs (Acinonyx jubatus) in Namibia 
    Tordiffe, Adrian Stephen Wolferstan; Wachter, Bettina; Heinrich, Sonja K.; Reyers, Fred; Mienie, Lodewyk J. (Public Library of Science, 2016-12-19)
    Cheetahs (Acinonyx jubatus) are highly specialised large felids, currently listed as vulnerable on the IUCN red data list. In captivity, they are known to suffer from a range of chronic non-infectious diseases. Although ...
  • Coping with intrasexual behavioral differences : capture–recapture abundance estimation of male cheetah 
    Edwards, Sarah; Fischer, Manuela; Wachter, Bettina; Melzheimer, Joerg (Wiley Open Access, 2018-09)
    Population estimates are a fundamental requirement of ecology and conservation. While capture–recapture models are an established method for producing such estimates, their assumption of homogeneous capture probabilities ...

(American Association for the Advancement of Science, 2022-05)
    The rate of adaptive evolution, the contribution of selection to genetic changes that increase mean fitness, is determined by the additive genetic variance in individual relative fitness. To date, there are few robust ...
