Freeman, Marc Trevor; Czenze, Zenon J.; Schoeman, Keegan; McKechnie, Andrew E. (National Academy of Sciences, 2022-06)Physiological performance declines precipitously at high body temperature (Tb), but little attention has been paid to adaptive variation in upper Tb limits among endotherms. We hypothesized that avian maximum tolerable ...

Czenze, Zenon J.; Freeman, Marc Trevor; Kemp, Ryno; Van Jaarsveld, Barry; Wolf, Blair O.; McKechnie, Andrew E. (Frontiers Media S.A., 2021-12-24)Avian evaporative cooling and the maintenance of body temperature (Tb) below lethal limits during heat exposure has received more attention in small species compared to larger-bodied taxa. Here, we examined thermoregulation ...

Freeman, Marc Trevor; Czenze, Zenon J.; Schoeman, K.; McKechnie, Andrew E. (Nature Publishing Group, 2020-08-04)The thermal tolerances of vertebrates are generally restricted to body temperatures below 45–47 °C, and avian and mammalian critical thermal maxima seldom exceed 46 °C. We investigated thermoregulation at high air ...

Van Jaarsveld, Barry; Bennett, Nigel Charles; Czenze, Zenon J.; Kemp, Ryno; Van de Ven, Tanja M.F.N.; Cunningham, Susan J.; McKechnie, Andrew E. (Company of Biologists, 2021-02)At a global scale, thermal physiology is correlated with climatic variables such as temperature and aridity. There is also evidence that thermoregulatory traits vary with fine-scale microclimate, but this has received ...

Lane, Jeffrey E.; Czenze, Zenon J.; Findlay-Robinson, Rachel; Bayne, Erin (University of Chicago Press, 2019-10)Phenological shifts are the most commonly reported ecological responses to climate change and can be produced rapidly by phenotypic plasticity. However, both the limits of plasticity and whether it will be sufficient ...

Czenze, Zenon J.; Kemp, Ryno; Van Jaarsveld, Barry; Freeman, Marc Trevor; Smit, Ben; Wolf, Blair O.; McKechnie, Andrew E. (Wiley, 2020-08)Surface water is a critical resource for many birds inhabiting arid regions, but the implications of regular drinking and dependence on surface water for the evolution of thermal physiology remain largely unexplored. ...
