Optimal allocation of energy to growth and reproduction.

The optimal allocation of energy to growth and reproduction is considered for three different cases, i.e., a single reproduction (semelparity), reproduction through repeated discrete clutches, and continuous reproduction. The problem reduces to optimizing age and size at maturity. The best strategy is to continue growth until the change of production rate with respect to increasing body size, multiplied by life expectancy for those attaining adulthood and reproducing successfully, is greater than one. The time at which semelparous species reproduce may also be optimized; for the other modes of reproduction only physiological factors or seasonality can limit the maximum age. A brief growing season or high mortality rate are factors leading to early maturity and small adult body size.

Influence of the male on provoked ovulation in immature female mice.

Acceleration of ovulation in juvenile females by exposure to the male and injection of gonadotrophins was investigated. The male-induced ovulation in CBA/kw and outbred females was observed only after injection of PMSG. Exposure to the male and injection of HCG did not evoke this effect. Our results indicated that the presence of a male stimulates LH release from the pituitary of juvenile females. Pheromonal reaction of the females was affected by the age and body weight of the tested animals. Most sensitive were females of CBA/kw strain 21-day-old, outbred 21-day-old, 10.0-12.0 g and 24-day-old, 7.5-9.5 g.
