  • Male blue wildebeest increase activity during the rut, but not at the expense of rest 
    Malungo, Illke B.; Gravett, Nadine; Ganswindt, Andre; Manger, Paul R. (Springer, 2023-04)
    Rest is a state of adaptive inactivity that increases the efficiency of activity by regulating its timing and reducing energy use when activity is not beneficial. Thus, animals can go without rest when specific demands, ...
  • 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 immigration triggers increased growth in subordinate female meerkats 
    Dubuc, Constance; Clutton-Brock, Tim H. (Wiley Open Access, 2019-02)
    There is increasing evidence that some vertebrates can adjust their growth rate in relation to changes in the social context that affect their probability of breeding. Here, we show that, in meerkats (Suricata suricatta), ...
