摘要: After weaning, collared lemmings (Dicrostonyx groenlandicus) were exposed to 3 months of summer (S) photoperiod (18.5L:5.5D) or winter (W) (6.5L: 17.5D) one four 6-month treatments (SS, SW, WW, WS). Lemmings weighed every weeks, and at the end treatment, eye lenses 10 body 22 skull measurements taken. At W, WW did not differ in weight, but significantly heavier than S, SS, WS lemmings. Animals those SS both S The marked contrast photoperiodically induced growth pattern Dicrostonyx groenlandicus with that other microtines may be due a relatively larger investment reproduction by died during experiment weight size survived. Eye lens weights W differ, bu...
