摘要: Maternally unsuccessful 2-year-old white-tailed deer (Odocoileus virginianus) bred later and conceived more male progeny compared to successful mothers of the same age. We hypothesize that social factors modified reproductive traits these does, they exhibited breeding characteristics typical yearlings. J. WILDL. MANAGE. 50(1):122-124 Earlier (Ozoga et al. 1982; Ozoga Verme 1982a, 1984) we suggested if a failed rear her fawn(s), she reverted back yearling age status in terms following season. Here document this phenomenon as evolutionary or adaptive value such behavior. This paper is contribution from Mich. Fed. Aid Wildl. Restoration Proj. W-127-R, Cusino Res. Stn. thank C. S. Bienz, R.
