Abstract
Each of 30 male deer mice, Peromyscus maniculatus bairdi, was provided the opportunity to copulate with 3 successive females for 1 h each. Male capacity was limited; only 22 males copulated with all 3 females and only 11 ejaculated with all 3 females. The amount of copulation decreased with successive females. The numbers of females pregnant in the three ordinal positions were 18, 15, and 8, respectively. However, for the males that ejaculated with a female, there was no decrease in potency across successive females; the decreases that did occur overall were due to males that did not mate. For deer mice, unlike other species, even relatively sensitive methods reveal that males cease copulating before marked decreases in the potency of their ejaculates develop.
