  • Assessment of male reproductive skew via highly polymorphic STR markers in wild vervet monkeys, Chlorocebus pygerythrus 
    Minkner, Mirjam M.I.; Young, Christopher; Amici, Federica; McFarland, Richard; Barrett, Louise; Grobler, J. Paul; Henzi, S. Peter; Widdig, Anja (Oxford University Press, 2018-10)
    Male reproductive strategies have been well studied in primate species where the ability of males to monopolize reproductive access is high. Less is known about species where males cannot monopolize mating access. Vervet ...
  • Climate induced stress and mortality in vervet monkeys 
    Young, Christopher; Bonnell, Tyler R.; Brown, Leslie R.; Dostie, Marcus J.; Ganswindt, Andre; Kienzle, Stefan; McFarland, Richard; Henzi, S. Peter; Barrett, Louise (Royal Society Publishing, 2019-11)
    As the effects of global climate change become more apparent, animal species will become increasingly affected by extreme climate and its effect on the environment. There is a pressing need to understand animal physiological ...
  • Common HLA Alleles associated with health, but not with facial attractiveness 
    Coetzee, Vinet; Barrett, Louise; Greeff, Jaco M. (Jacobus Maree); Henzi, S. Peter; Perrett, David Ian; Wadee, Ahmed A. (Public Library of Science, 2007-07)
    Three adaptive hypotheses have been proposed to explain the link between the human leucocyte antigen (HLA) genes, health measures and facial attractiveness: inbreeding avoidance, heterozygote advantage and frequency-dependent ...
  • Facial-based ethnic recognition : insights from two closely related but ethnically distinct groups 
    Coetzee, Vinet; Greeff, Jaco M. (Jacobus Maree); Barrett, Louise; Henzi, S. Peter (Academy of Science of South Africa, 2009-11)
    Previous studies on facial recognition have considered widely separated populations, both geographically and culturally, making it hard to disentangle effects of familiarity with an ability to identify ethnic groups per ...
  • 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 ...
  • Gastrointestinal parasites of vervet monkeys (Chlorocebus pygerythrus) in a high latitude, semi-arid region of South Africa 
    Blersch, Rosemary; Archer, Colleen; Suleman, Essa; Young, Christopher; Kindler, Duodane; Barrett, Louise; Henzi, S. Peter (American Society of Parasitologists, 2019-08)
    Given a changing climate and large-scale human migration, understanding infectious diseases in wildlife and the factors that drive the spread of these diseases is becoming increasingly important. Owing to the close ...
  • Infrared thermography cannot be used to approximate core body temperature in wild primates 
    McFarland, Richard; Barrett, Louise; Fuller, Andrea; Hetem, Robyn S.; Porter, Warren P.; Young, Christopher; Henzi, S. Peter (Wiley, 2020-12)
    Understanding the physiological processes that underpin primate performance is key if we are to assess how a primate might respond when navigating new and changing environments. Given the connection between a mammal's ...
  • 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 ...
  • Network integration and limits to social inheritance in vervet monkeys 
    Jarrett, Jonathan D.; Bonnell, Tyler R.; Young, Christopher; Barrett, Louise; Henzi, S. Peter (The Royal Society, 2018-04)
    Social networks can be adaptive for members and a recent model (Ilany and Akçay 2016 Nat. Comm. 7, 12084 (doi:10.1038/ncomms12084)) has demonstrated that network structure can be maintained by a simple process of social ...
  • 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, ...
