TL;DR
It is concluded that breeding in rice fields in spring is limited by the food supply, and it is probably the supply of energy, rather than that of specific nutrients, that is limiting.
Abstract
Free-ranging populations of house mice, Mus musculus L., on contour banks in a rice field in New South Wales were provided with three types of supplementary food of differing nutritional quality for 10 weeks in spring. Four live-trapping sessions were conducted 3-10 weeks after supplementary feeding started. The percentage of females breeding averaged 47% on banks with supplementary food, and 0% on control banks with no supplementary food. The quality of the supplementary food did not affect breeding performance. It is concluded that breeding in rice fields in spring is limited by the food supply, and it is probably the supply of energy, rather than that of specific nutrients, that is limiting.

The reproductive biology of the house mouse seems uniquely suited to support ecological opportunism, and the relatively few environmental inhibitors of reproduction in this species should enhance the ability of dispersing young to colonize an exceptionally wide variety of habitats and climates.

In breeding populations, mortality and dispersal of juveniles and subadults increased markedly as density increased, whereas during the nonbreeding season, those parameters were not affected by the weight of an animal, density, or supplemental food.

The data suggest that Microtus montanus cues reproductive effort from chemical signals in the plant food resources, and that the population receiving limited supplements of fresh green wheatgrass over a 2-week period is likely to be pregnant.

It is suggested that photoperiods that simulate those of winter induce regression of the reproductive organs of male California voles but the availability of green vegetation counteracts the inhibitory effects of short daylengths.

Field evidence is presented in support of the concept that Microtus montanus cues reproduction to chemical compounds in the plants it eats, which exerts a major influence on population recruitment rates.

The diet and breeding seasons of house mice were monitored for 16 months in six habitats on two cereal farms: fields of barley, wheat, sorghum and rice stubble, and contour banks in rice fields, and channel banks, and in all habitats mice were mainly granivorous.

31 Citations1981Susan Pryor, F. H. Bronson
Two generalities are suggested regarding the relationship between diet and reproduction in natural populations of house mice: first, house mice, being opportunists, probably often invade habitats that offer only a reproductively marginal diet, and hence most populations of this species probably do not breed at maximum efficiency even at intermediate temperatures, and secondly, when winter cessations of breeding occur in house mice they probably typically result from the combined effects of a marginal diet and a low ambient temperature.

No significant alterations in the plasma values of LH and FSH were observed in mice underfed between Days 1 and 9 of pregnancy, which may indicate that progesterone secretion between Days 5 and9 of gestation is not controlled solely by LH.

Present in many plants, especially during germination, growth and seed maturation, gibberellins may be proximate chemical cues to reproduction in some herbivores, and may act as a feedback mechanism between plant and herbivore in some models of demographic cycles.
