Fig. 5. Flexible response of the liver to feeding measured from ultrasonographs.
Multiple measurements of each individual were averaged by individual and day;
to account for size differences among individuals, measurements are expressed
relative to the size (cross-sectional diameter) of the liver of each
individual on the day before the experiment started. Values are means ±
S.D. from the four snakes in each group. Dotted lines indicate feeding events.
(A) Fasting snakes, open symbols; (B) snakes fed every other day, black
symbols; grey symbols are for snakes that did not feed; (C) snakes fed once a
week, grey symbols.
