Whether the nights were classified as cold(N = 2),intermediate
(N = 6)or warm(N = 6),there was no significant treatment-by-
origin interaction effect on activity(P = 0.78).Likewise,the difference among origins did not change depending on
temperature class(P = 0.46).The treat ments differed inactivity,however,
depending on temperature class(P < 0.01).In all three temperature
classes,activity in DARK was higher than under AMB(P < 0.001),
but on warm nights the difference between mean activity in DARK
(0.98)and AMB(0.56)was smaller than on cold(0.82 vs. 0.18) or
intermediate(0.96 vs. 0.46) nights.
