TL;DR
The hypothesis that meadow vole populations are influenced by the quality and quantity of food available throughout the year is tested by establishing two live-trap plots and one snap-trap plot.
Abstract
(1) This study tested the hypothesis that meadow vole (Microtus pennsylvanicus (Ord)) populations are influenced by the quality and quantity of food available throughout the year. (2) Two live-trap plots and one snap-trap plot, each c. 0 8 ha, were established in a strip of vole habitat surrounded by unfavourable habitat. The snap-trap plot was between the two live-trap plots so that movement from the two live-trapped populations could be monitored.

This chapter summarizes the current information on population cycles in small rodents, and first looks at the general questions about cycles, and then discusses the demographic machinery which drives the changes in numbers.

The demography of these Microtus species in southern Indiana is similar to that of other cycle voles and lemmings in temperate and arctic areas, since fenced populations seem unable to regulate their density below the limit set by starvation.

Dispersal was most common during the fall and winter, and in the phase of population increase 59% of male and 69% of female Microtus pennsylvanicus loss from two control populations could be accounted for by dispersal.

A computer simulation of the capture–recapture process was used to examine the influence of five population parameters on the reliability of enumeration, and it was concluded that enumerated populations are at least 10–20% smaller than the actual populations.

It is indicated that nutritive factors could be involved in microtine population cycles at low latitudes and point to the need for further research on diet quality and nutritional physiology of Microtus.

It is concluded that quality of available food influences the amplitude of population fluctuations of the prairie vole, but some other factor(s) must initiate the periodic declines.

The results of this research suggest that the vole's population size is limited by both behaviour and food, and that a viable surplus of voles exists in natural populations.

If spacing behavior limits the breeding density of small mammals, the colonization of vacant areas by surplus animals ought to show how and when population regulation is achieved.

Demographic processes associated with the onset of breeding in spring are examined in a population of deer mice, Peromyscus maniculatus, and two hypotheses relating the population processes of males to those of females are presented.

108 Citations1977Robert H. Tamarin
It is suggested that the mainland population has selective dispersal leading to cycles, whereas the island has a simple drainage of excess recruits, no selection by way of dispersal, and subsequently no cycles.

About 1,200 Microtus pennsylvanicus and M. ochrogaster were collected over a 3—year period by sequential trapping of snap—trap lines in southern Indiana to determine whether weight at sexual maturity, pregnancy rate, living embryo production, prenatal mortality, and body weight varied in relation to fluctuations in numbers.

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.

Numbers of the California vole declined rapidly in spite of excellent individual growth rates and a sustained high reproductive rate among the adults, indicating supplemental food was not sufficient to produce a rapidly expanding population or to prevent a decline to low numbers.

It is proposed that the animals that dominated the dispersal samples each season were moving in response to social pressure from residents, or local limitations of some resource, and thus, that dispersal was adaptive for the individuals concerned.

68 Citations1978Charles J. Krebs, Rudy Boonstra
It is suggested that spring declines in both sexes of M. townsendii are produced by spacing behaviour, but it is not known if differences in spacing behaviour are sufficient to explain all variations in spring declines.

Eight 0.1-ha small-mammal enclosures were stocked with house mice on 6 June 1975 and mice were allowed to populate all grids until late December 1975, found to have similar assimilation efficiencies no matter where they were trapped in the grids.

Overall population growth was similar to that of other enclosed populations, thus emphasizing the importance of dispersal in normal demography, and suggested features of this vole's social system are small group size, a tendency toward monogamy, strong presaturation dispersal, and only weak social inhibitions of reproduction.

Population structure and reproductive condition of the meadow vole, Microtus pennsylvanicus, were analyzed for the period of July 1954 through July 1955, when there was a heavy snow cover throughout the winter and breeding was recorded for every month of the year.

Previously published records of male spring body weights from several parts of Britain were found to be significantly correlated with the standing crop of a meadow at Moor House Experimental Station and with the hay yields of the unfertilized control plots in the Rothamsted Park Grass Experiment, suggesting a link between vole population fluctuations and climate.
