Body Size, Physiological Time, and Longevity of Homeothermic Animals
TLDR
Life span, like the other scales of physiological time, may be regarded, not as a direct product of natural selection, but rather as an allometric consequence of other characteristics subjected to natural selection.

The Integration of Osmoregulation and Energy Balance in Hummingbirds
TLDR
The hummingbird is a unique animal: its kidney appears to be structurally similar to that of a reptile, but its rate of waterflux is more typical of an amphibian; it sustains a metabolic level as high as that of any endotherm.

Respiratory and Heart Rates of Birds at Rest
  • W. Calder
  • Biology, Environmental Science
  • 1 October 1968
The respiratory rates of birds are inversely related to their body weights (Groebbels 1932; Salt and Zeuthen 1960). Odum (1945) noted that birds breathe at lower frequencies than do mammals of…

  • 1 June 1971
TLDR
The increasing availability of data on commonly measured physiological and anatomical features permits allometric consideration of convergence, giving rather far-reaching implications and suggestions from such a simple technique.
