    Brain Function Research Unit, School of Physiology, University of the Witwatersrand, South Africa
    Am J Physiol Regul Integr Comp Physiol 290:R405-13. 2006
    ..We conclude that serotonergic drugs that act on 5-HT1A, 5-HT7, and 5-HT4 receptors reverse opioid-induced respiratory depression and hypoxia without reversing catatonic immobilization...

    Comp Biochem Physiol A Mol Integr Physiol 152:379-88. 2009
    ..White springbok, by contrast, were more protected from solar heat load, but potentially less able to meet the energy cost of homeothermy in winter. Thus energy considerations may underlie the rarity of the springbok colour morphs...

    ..05), indicating improved oxygen diffusion. Metoclopramide and buspirone transiently improved blood oxygenation of opioid-immobilized impala, probably by improving ventilation-perfusion ratios, without reversing catatonic immobilization...

    ..46, P = 0.014). We therefore have recorded quantitative evidence for autonomic and behavioral fever, as well as sickness behavior, in the form of decreased activity, in a free-living ungulate species...

    Leith C R Meyer

    J Wildl Dis 44:404-16. 2008
    ..Therefore we believe that capture-induced hyperthermia in impala is caused predominantly by stress, which induces a rapid rise in body temperature...

    School of Physiology, University of the Witwatersrand Medical School, Parktown, South Africa
    Am J Physiol Regul Integr Comp Physiol 300:R1409-17. 2011
    ..We conclude that the AOV is not the only conduit for venous drainage contributing to SBC in sheep and that, contrary to widely held opinion, control of SBC does not involve changes in the vasomotor state of the AOV...

    J Exp Zool A Ecol Genet Physiol 307:342-56. 2007
    ..We, therefore, have developed an ambulatory device, which can be attached to free-ranging animals, to remotely quantify thermoregulatory behaviour and selected microclimates...
