  • Faecal glucocorticoid metabolite monitoring as a measure of physiological stress in captive and wild vervet monkeys 
    Young, Christopher; Ganswindt, Andre; McFarland, Richard; De Villiers, Charon; Van Heerden, Joritha; Ganswindt, Stefanie Birgit; Barrett, Louise; Henzi, S. Peter (Elsevier, 2017-11)
    The development of non-invasive techniques to analyse physiological stress in mammalian species has revolutionised field-based endocrinology. However, careful validation of the methods used to determine faecal glucocorticoid ...
  • Male characteristics as predictors of genital color and display variation in vervet monkeys 
    Young, Mirjam M.I.; Winters, Sandra; Young, Christopher; Weiß, Brigitte M.; Troscianko, Jolyon; Ganswindt, Andre; Barrett, Louise; Henzi, S. Peter; Higham, James P.; Widdig, Anja (Springer, 2020-01)
    In the animal kingdom, conspicuous colors are often used for inter- and intra-sexual communication. Even though primates are the most colorful mammalian taxon, many questions, including what potential information color ...
  • Male residency and dispersal triggers in a seasonal breeder with influential females 
    Young, Christopher; McFarland, Richard; Ganswindt, Andre; Young, Mirjam M.I.; Barrett, Louise; Henzi, S. Peter (Elsevier, 2019-08)
    Males in female-philopatric social groupings leave their natal groups to pursue successive reproductive opportunities in one or more other groups. In vervet monkeys, Chlorocebus pygerythrus, adult males coexist and physical ...
  • Sick and tired : sickness behaviour, polyparasitism and food stress in a gregarious mammal 
    Blersch, Rosemary; Bonnell, Tyler R.; Ganswindt, Andre; Young, Christopher; Barrett, Louise; Henzi, S. Peter (Springer, 2021-12)
    Although sickness behaviour in response to non-lethal parasites has been documented in wild animals, it remains unclear how social and environmental stress might also shape an animal’s behavioural response to parasitism, ...
