Growth rates in two closely related species, Alligator mississippiensis (American alligator) and Alligator sinensis (Chinese alligator), were compared under identical conditions for at least 1 year after hatching. When hatched, Chinese alligators wer

1. 1. Rates of protein digestion, amino acid absorption and amino acid assimilation were determined in alligators at 31, 25, 20, 15 and 10°C. 2. 2. The rates were roughly proportional to cardiac output as determined from heart rate, oxygen consumpti

SUMMARY. A young, captive-bred Harris's hawk, Parabuteo unicinctus, exhibited high fever and apparent paralysis of one leg shortly before death. Postmortem examination revealed milky white kidneys, white crystalline deposits in the pericardial sack,

1. 1. Tissues of Anolis carolinensis were analyzed for free amino acids after injection of lysine, α-aminoadipate, glutarate, glutaconate or acetate. 2. 2. All compounds except acetate produced glutamine in liver, kidney and muscle, but lysine was t

1. 1. Injection of carbonic anhydrase inhibitors into live chameleons and alligators (a) prevented the hyperglycemia normally observed after work-induced glycolysis, (b) inhibited restoration of muscle glycogen, as evidenced by a smaller than normal

Synopsis. The metabolic rate of the alligator is a direct function of the volume of blood flowing through the capillaries/unit time/unit weight, which in turn, is determined by the heart rate and the stroke volume. For an animal with such a low metab

1. 1. The metabolic rate of the shrew is about 60 times that of man, whose metabolic rate in turn is about 60 times that of a grown male alligator. 2. 2. Estimates of the following biochemical and physiological parameters were compared in the three a

1. 1. Crocodilians were force-fed fish muscle or mixed amino acids or were injected with mixed amino acids. 2. 2. In those receiving mixed amino acids per Os or i.p., amino acids disappeared at a rate of 122 mmoles/kg per day at 28°C. 3. 3. Energy n

1. 1. Alligators fed ab lib 5 days a week excreted the same amount of uric acid/day, but much more ammonia/day, than those fed a single meal after a long fast. 2. 2. Plasma levels of ammonia (and uric acid) precursors were the same in the two groups.
