Re: NEED BIRD RESPIRATION REF

["Michael E Teuton" <tons@netside.com>]

Greg,

I don't currently have this and haven't looked at it in a while, but you
might try Krogh,A. 1968. "The Comparative Physiology of Respiratory
Mechanisms."  I can reply latter with a more thorough list.

I think some previous miscommunication about costs of locomotion may have
arisen from the fact that cost of transport (COT) in J/kg/m plotted against
body mass on logarithmic coordinates is linear.  COT vs velocity in m/s is
curvilinear.

See also, Langman, V A. J of Experimental Biology 198, 629-632 (1995),
"Moving Cheaply:  Energetics of Walking in the African Elephant."  for
references on elephant locomotion.

Best,

Michael
