    Anim Cogn 9:229-33. 2006
    ..The undertaking of such tasks by common marmosets in situ probably provides a more reasonable representation of the levels of cognitive capacity expressed by this species in the wild than do laboratory-based studies of the task...

    Lewis G Halsey
    School of Biosciences, University of Birmingham, UK
    Physiol Biochem Zool 78:273-84. 2005
    ..Given that tufted ducks normally dive well within their aerobic dive limits and that they significantly reduced their t(d) during hypoxia, it is not at all clear why they make this physiological adjustment...

    Am J Physiol Regul Integr Comp Physiol 295:R92-R100. 2008
    ..These results suggest that the lowering of avUCP activity during periods of long-term energetic restriction may contribute to the reduction in metabolic rate and hence the ability of king penguins to face prolonged periods of fasting...
