Hermaphrodites and parasitism: size-specific female reproduction drives infection by an ephemeral parasitic castrator

Age-specific Reproduction by Female Laughing Gulls (larus Atricilla)

Effects of postnatal litter size on reproduction of female mice.

A group of 98 dams weaned 588 female mice to be mated and allowed to reproduce. These females were assigned at birth to be reared in a litter of eight or 14 mice. Such litters were intended to represent postnatal environments equivalent to small and large litters. However, average litter size was approximately 15 mice in this line and comparisons were more correctly those between small and aver...

Early social conditions affect female fecundity in hermaphrodites

Social conditions experienced prior to sexual maturity influence reproduction later in life in many animals. In simultaneous hermaphrodites variation in mating group size influences reproductive investment. As the mating group size increases, reproductive resources devoted to the female function decrease in favor of the male function. Prior to sexual maturity many hermaphrodites have a protandr...
