In the course of studying taste discrimination in rats, Dr. Curt Richter gave some of his rats small amounts of alpha-naphtha-thio-urea. This substance, more simply designated ANTU, rather than proving to be a tool for studying taste discrimination, acted as a highly lethal p0ison.l Since it was so specific for rats (Rattus norvegicus only), it was thought that it might be a panacea for effectively eliminating this pest. With this as the stimulus, Johns Hopkins University and the City of… Expand
The Characteristics of Rat Populations

  • 1953
TLDR
The characteristics of a particular group of animals (a population) is the subject of this review, which is concerned with populations of wild rats and the species Rattus norvegicus is the best known of more than 400 named forms in the genus Rattus. Expand
Social Behavior, Reproduction, and Population Changes in the House Mouse (Mus musculus L.)
The present study of the interrelations of social behavior, reproduction, and population changes in the house mouse (Mus musculus L.) was undertaken in an effort to understand some of the aspects ofExpand
Escaping the Laboratory: The Rodent Experiments of John B. Calhoun & Their Cultural Influence
In John B. Calhoun's early crowding experiments, rats were supplied with everything they needed—except space. The result was population boom, followed by such severe psychological disruption that theExpand
Food deprivation at weaning and adult behavior elicited by hypothalamic stimulation in the rat.
TLDR
It was concluded that a biologically important experience can have a lasting effect on the hierarchy of behaviors elicited by hypothalamic stimulation and Stimulus-bound digging was an unexpectedly prominent behavior. Expand
The Relationship between Adrenal Weight and Population Status of Urban Norway Rats
TLDR
The present experiments were designed to examine natural populations for a corresponding relationship between population density and adrenal weight in natural populations. Expand

A Contribution to the Study of the Social Behavior of the Wolf
TLDR
Three wolf cubs taken blind from their den were studied in captivity in the presence of individuals of two breeds of dogs (German Shepherd and Samoyed) and no difference was observed in the movements and behavior patterns of these two species. Expand

Experimental induction of territorial behavior in the deer mouse, Peromyscus maniclatus
TLDR
It was determined that territorial behavior was subject to seasonal variation and no relationship between territorial behavior and the reproductive state of male deer mice was discernible, through experimental induction of territorial behavior within the laboratory. Expand

  • R. Pearl
  • Biology

TLDR
It is shown with devastating clarity that a great human population may be subjected to experimentation just as easily and ruthlessly as a Drosophila population in a pint bottle, and far more irresponsibly than would be tolerated in any respectable biological laboratory. Expand
The Rate of Recovery of Decimated Populations of Brown Rats in Nature
TLDR
The nature of population growth from a single pair of individuals to "population maturity" has been studied with various lower animals in stable laboratory environments and information is also available on the rate of increase of cyclic species, such as the snow-shoe rabbit during the recovery phase of a ten-year cycle.

TLDR
This program emphasizes suppressive measures as opposed to exclusion measures (rat-proofing), and is based on the fundamental premise that the rat population of a city block is essentially isolated so that it can be treated as an independent unit. Expand
