... to progressive decreases in inspired oxygen levels of bar-headed geese ( Anser indicus ), birds that biannually migrate across the Himalayan mountains, with those of Andean geese ( Chloephaga melanoptera ) and crested ducks ( Lophonetta specularioides ), lifelong residents of the high Andes. We show that Andean...

...-dimensionally complex and not visible externally. Here we use a new in vivo X-ray motion analysis technique, X-ray reconstruction of moving morphology (XROMM), to create precise (±0.06 mm) 3-D animations of the quadrate, braincase, upper bill and mandible of three mallard ducks, Anas platyrhynchos . We defined...

... (measured using tendon buckle transducers) and length change (measured using sonomicrometry) were obtained from mallard ducks (Anas platyrhynchos) as they swam at steady speeds in a water tank and walked or ran on land. LG force recordings were compared with combined lateral and medial gastrocnemius (MG...

...P. J. Butler; D. L. Turner; A. Al-Wassia; R. M. Bevan ABSTRACT The distribution of blood flow to a number of organs and tissues of the tufted duck was determined (by the microsphere technique) before and while the birds were swimming at close to their maximum sustainable velocity (i.e. at 0·69 ± 0...

...D. Nguyen Phu; K. Yamaguchi; P. Scheid; J. Piiper ABSTRACT The specific conductance (G) for O 2 transfer by red blood cells (RBCs) of chicken and muscovy duck was measured using the experimental (stopped-flow) and analytical techniques (RBC model) previously applied to human RBC ( Yamaguchi, Nguyen...

...A. J. Woakes; P. J. Butler ABSTRACT Respiratory, and some cardiovascular and metabolic, variables were measured in tufted ducks swimming at different velocities. There were no substantial changes in any of the measured variables up to a swimming speed of 0·5 m s −1 . Above this speed there were...
