Fig. 4. (A) Abdominal temperatures in resting Greenland great cormorants throughout
the year cycle. Filled circles, abdominal temperatures of animals resting
during the non-active phase (02:00-05:00 h); empty circles, abdominal
temperatures of animals resting during the active phase (10:00-15:00 h). One
data point is shown every eighth day; values are means + S.D.
(N=3-7). (B) Abdominal temperatures of foraging Greenland great
cormorants throughout the year cycle. Filled circles, abdominal temperatures
of diving animals; empty circles, abdominal temperatures of animals after a
diving sequence. One data point is shown every eighth day; values are means +
S.D. (N=3-7). (C) Effect of diving on the abdominal
temperature of Greenland great cormorants throughout the year cycle.
T was measured between the moment of the first and the last
dive within the dive series. One data point is shown every eighth day; values
are means + S.D. (N=3-7).
