  • 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 ...
  • Dominance style is a key predictor of vocal use and evolution across nonhuman primates 
    Kavanagh, Eithne; Street, Sally E.; Angwela, Felix O.; Bergman, Thore J.; Blaszczyk, Maryjka B.; Bolt, Laura M.; Briseño-Jaramillo, Margarita; Brown, Michelle; Chen-Kraus, Chloe; Clay, Zanna; Coye, Camille; Emery Thompson, Melissa; Estrada, Alejandro; Fichte, Claudia; Fruth, Barbara; Gamba, Marco; Giacoma, Cristina; Graham, Kirsty E.; Green, Samantha; Grueter, Cyril C.; Gupta, Shreejata; Gustison, Morgan L.; Hagberg, Lindsey; Hedwig, Daniela; Jack, Katharine M.; Kappeler, Peter M.; King-Bailey, Gillian; Kuběnová, Barbora; Lemasson, Alban; Inglis, David MacGregor; Machanda, Zarin; MacIntosh, Andrew; Majolo, Bonaventura; Marshall, Sophie; Mercier, Stephanie; Micheletta, Jérôme; Muller, Martin; Notman, Hugh; Ouattara, Karim; Ostner, Julia; Pavelka, Mary S. M.; Peckre, Louise R.; Petersdorf, Megan; Quintero, Fredy; Ramos-Fernández, Gabriel; Robbins, Martha M.; Salmi, Roberta; Schamberg, Isaac; Schoof, Valérie A. M.; Schülke, Oliver; Semple, Stuart; Silk, Joan B.; Sosa-Lopéz, J. Roberto; Torti, Valeria; Valente, Daria; Ventura, Raffaella; Van de Waal, Erica; Weyher, Anna H.; Wilke, Claudia; Wrangham, Richard; Young, Christopher; Zanoli, Anna; Zuberbühler, Klaus; Lameira, Adriano R.; Slocombe, Katie (The Royal Society, 2021-07)
    Animal communication has long been thought to be subject to pressures and constraints associated with social relationships. However, our understanding of how the nature and quality of social relationships relates to the ...
  • 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 ...
  • Formidable females redux: male social integration into female networks and the value of dynamic multilayer networks 
    Bonnell, Tyler R.; Vilette, Chloe; Young, Christopher; Henzi, Stephanus Peter; Barrett, Louise (Oxford University Press, 2021-02)
    The development of multilayer network techniques is a boon for researchers who wish to understand how different interaction layers might influence each other, and how these in turn might influence group dynamics. Here, we ...
  • 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 ...
  • Modeling variation in the growth of wild and captive juvenile vervet monkeys in relation to diet and resource availability
