  • Arabian oryx (Oryx leucoryx) respond to increased ambient temperatures with a seasonal shift in the timing of their daily inactivity patterns 
    Davimes, Joshua G.; Alagaili, Abdulaziz N.; Gravett, Nadine; Bertelsen, Mads F.; Mohammed, Osama B.; Ismail, Khairy; Bennett, Nigel Charles; Manger, Paul R. (Sage, 2016-08)
    The Arabian oryx inhabits an environment where summer ambient temperatures can exceed 40 °C for extended periods of time. While the oryx uses a suite of adaptations that aid survival, the effects of this extreme environment ...
  • Cellular scaling rules for the brain of afrotherians 
    Neves, Kleber; Ferreira, Fenanda M.; Tovar-Moll, Fernanda; Gravett, Nadine; Bennett, Nigel Charles; Kaswera, Consolate; Gilissen, Emmanuel; Manger, Paul R.; Herculano-Houzel, Suzana (Frontiers Research Foundation, 2014-02)
    Quantitative analysis of the cellular composition of rodent, primate and eulipotyphlan brains has shown that non-neuronal scaling rules are similar across these mammalian orders that diverged about 95 million years ago, ...
  • Excessive red tape is strangling biodiversity research in South Africa 
    Alexander, Graham J.; Tolley, Krystal A.; Maritz, Bryan; McKechnie, Andrew E.; Manger, Paul R.; Thomson, Robert L.; Schradin, Carsten; Fuller, Andrea; Meyer, Leith Carl Rodney; Hetem, Robyn S.; Cherry, Michael; Conradie, Werner; Bauer, Aaron M.; Maphisa, David; O’Riain, Justin; Parker, Daniel M.; Mlambo, Musa C.; Bronner, Gary; Madikiza, Kim; Engelbrecht, Adriaan; Lee, Alan T.K.; Jansen van Vuuren Bettine; Mandiwana-Neudani, Tshifhiwa G.; Pietersen, Darren William; Venter, Jan A.; Somers, Michael J.; Slotow, Rob; Strauss, W. Maartin; Humphries, Marc S.; Ryan, Peter G.; Kerley, Graham I.H. (Academy of Science of South Africa, 2021-09)
    Preventing the over-exploitation of natural resources is vital to ensure that biodiversity is protected and conserved. Legislation and regulations are therefore necessary to manage resource utilisation, but overly stringent ...
  • Locally-curved geometry generates bending cracks in the African elephant skin 
    Martins, Antonio F.; Bennett, Nigel Charles; Clavel, Sylvie; Groenewald, Hermanus B.; Hensman, Sean; Hoby, Stefan; Joris, Antoine; Manger, Paul R.; Milinkovitch, Michel C. (Nature Publising Group, 2018-10-02)
    An intricate network of crevices adorns the skin surface of the African bush elephant, Loxodonta africana. These micrometre-wide channels enhance the effectiveness of thermal regulation (by water retention) as well as ...
  • 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, ...
  • Microbats appear to have adult hippocampal neurogenesis, but post-capture stress causes a rapid decline in the number of neurons expressing doublecortin 
    Chawana, R.; Alagaili, Abdulaziz N.; Patzke, Nina; Mohammed, Osama B.; Kaswera, Consolate; Gilissen, Emmanuel; Bennett, Nigel Charles; Ihunwo, Amadi O.; Manger, Paul R.; Spocter, M.A. (Elsevier, 2014-09)
    A previous study investigating potential adult hippocampal neurogenesis in microchiropteran bats failed to reveal a strong presence of this neural trait. As microchiropterans have a high field metabolic rate and a small ...
