Variable responses to high density of female Mus musculus: A merger of two population regulation hypotheses.

摘要: Grouping of female Mus musculus resulted in an increase mean estrous cycle length from 4 to 12 days, yet some short cycles were still observed. Short attributed certain females who consistently maintained a cycling pattern as well exhibited both and long cycles. Upon breeding, that continued show when grouped produced weaned more young than with suppressed No differences weaning weight or sex ratio the litters was The ecological evolutionary implications these findings are discussed.
