摘要: Abstract The circadian caecotrophy rhythm of 15 rabbits a group 1 and 12 2 was continuously monitored in LD 12:12, 14:10, 16:8, 18:6, 20:4, 22:2. photoperiod extended opposite directions either by advancing the onset (group 1) or delaying end 2) photoperiod. response animals to extension differed significantly both between groups within during different steps extension. Generally advanced one delayed two. shift rate at respective new schedule determined phasically changing sensitivity rabbit light stimulation. results showed that is entrained predominantly non‐parametrically, while timeratio importance mainly for precision phase control.
