TL;DR
Fire was applied in late July 1969, to one of two comparable 0.4-ha fenced enclosures, each previously planted in oats and stocked with three species of small mammals, house mice, deer mice, and meadow voles, whereas all three species prevailed in the control grid.
Abstract
Fire was applied in late July 1969, to one of two comparable 0.4-ha fenced enclosures, each previously planted in oats ( Avena sativa ) and stocked with three species of small mammals, house mice ( Mus musculus ), deer mice ( Peromyscus maniculatus ), and meadow voles ( Microtus pennsylvanicus ). By late winter both Mus and Microtus had disappeared from the burned grid, whereas all three species prevailed in the control grid. Mus reached a population density of approximately 120 individuals in the unburned grid during March 1970. Oat seeds helped to account for this population explosion. Microtus failed to reproduce in both enclosures throughout the study. Peromyscus population density was reduced approximately 50% after fire treatment. There was no evidence that fire directly killed any small mammals.

The principles of ecological succession bear importantly on the relationships between man and nature and needs to be examined as a basis for resolving man’s present environmental crisis.

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.
EcologyImportance of Vegetative Cover to Cycles of Microtus Populations

A hypothesis is presented that a site-dependent threshold level of vegetative cover is necessary for a population of Microtus to increase in numbers sufficiently to undergo a multi-year cycle.

Although the insecticide remained toxic in the environment for only a few days, long-term side effects on litter decomposition, arthropod density and diversity, and mammalian reproduction were demonstrated and will provide a model for an ecosystem approach to the testing of pesticides.

Data from a laboratory study of the two species in artificial burrow systems indicated that Microtus caused mortality of Mus nestlings, and the rate of population increase for Mus was halved in the presence of Micortus.

An intensive study of small mammal populations in a clover field before and after experimental spraying with dimethoate, an organic phosphate insecticide, at levels that might be used in routine agriculture found no evidence that the insecticide caused direct mortality in any of the mammal species or had any additional effect on the habitat.

The peak standing crop biomass of herbaceous shoots, a measure of net primary shoot production, was determined in three first-year old fields by two methods: sampling the peak community standing crop at one moment and summing the peaks of the individual species over the entire growing season.

It is suggested that the restriction placed on dispersal by the enclosure walls and the addition of food in the form of trap bait could have allowed the enclosed populations of pine mice to reach higher densities than normally observed at SRP.
