| Zusammenfassung: | Relative numbers of inseminations occurring during the first 4 days after pairing were compared in deermice which had been housed 1, 4, or 10 females per cage for the 2 weeks preceding pairing. Females crowded 10 per cage before pairing showed a characteristic peak in estrous activity 3 days after pairing; those isolated before pairing showed no such peak; and females housed 4 per cage before pairing were intermediate. Topical (nose) exposure of females to male urine for 2 days before pairing accelerated attainment of estrus when compared with controls exposed to female urine. Male-induced synchrony of estrus in deermice appears to operate in a manner similar to that previously described for house mice. |
