摘要:

An increase in body temperature (Tb) observed in pinealectomized (Px) early winter pigeons as opposed to sham‐operated (SPx) ones, at two as well as three weeks post‐surgery, was found to have disappeared when examined one year later during corresponding season. Following this one‐year post‐surgery period under 12‐h daily photoperiod and 25°C ambient temperature (Ta), neither a 3‐week exposure to continuous light nor a 1‐week exposure to continuous darkness was found to produce any difference in Tbbetween Px and SPx pigeons.
