Role of the nutritional status of the litter and length and frequency of mother-litter contact bouts in prolonging lactational diestrus in rats.

abstract：:To determine across-year patterns in plasma testosterone (T) and corticosterone (B) levels in free-living birds, we took blood samples in the same 2-week breeding period during 4 consecutive years from territorial male red-winged blackbirds. We used our data to test predictions of the "challenge hypothesis" of T secre...
