Centre for Ornithology, School of Biosciences, University of Birmingham, Edgbaston, Birmingham B15 2TT, UK
Biol Lett 3:574-6. 2007..The period of descent in all the dives undertaken appears to have been more expensive when the birds foraged on sedentary prey, probably due to a higher swimming speed during this period...- Can wild common marmosets (Callithrix jacchus) solve the parallel strings task?L 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... - Control of ventilation in diving birdsPatrick J Butler

Universite de Lyon, Lyon, F 69003 France
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... - Moving towards acceleration for estimates of activity-specific metabolic rate in free-living animals: the case of the cormorantRory P Wilson
