  • Making use of multiple surveys : estimating breeding probability using a multievent‐robust design capture–recapture model 
    Oosthuizen, Wessel Christiaan; Pradel, Roger; Bester, Marthan Nieuwoudt; De Bruyn, P.J. Nico (Wiley Open Access, 2019-01)
    Increased environmental stochasticity due to climate change will intensify temporal variance in the life‐history traits, and especially breeding probabilities, of long‐lived iteroparous species. These changes may decrease ...
  • 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)

  • Male field cricket song reflects age, allowing females to prefer young males 
    Verburgt, Luke; Ferreira, M.; Ferguson, Jan Willem Helenus (Elsevier, 2011-01)
    Sexual selection often involves female preference for males of a certain age, and a body of theory predicts preference for old males. We measured a comprehensive set of traits from the acoustic sexual display of male ...
  • 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), ...
  • 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 ...
  • Mammalian herbivore movement into drought refugia has cascading effects on savanna insect communities 
    Trisos, Matthew O.; Parr, Catherine Lucy; Davies, Andrew Byron; Leitner, Monica; February, Edmund C. (Wiley, 2021-07)
    Global climate change is predicted to increase the frequency of droughts, with major impacts on tropical savannas. It has been suggested that during drought, increased soil moisture and nutrients on termite mounds could ...

    To understand and predict current and future distributions of animals under a changing climate it is essential to establish historical ranges as baselines against which distribution shifts can be assessed. Management ...
  • Mandibular gland pheromone contents in workers and queens of Apis mellifera adansonii 
    Yusuf, Abdullahi Ahmed; Pirk, Christian Walter Werner; Crewe, Robin M. (Springer, 2015-07)
    Secretions from the mandibular glands of honeybees have been studied extensively, with those of queens dominated by ώ-9 fatty acids and ώ-10 fatty acids dominating those of non-laying workers. Apis mellifera adansonii ...
