Behavioral sink
"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation.The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. In the experiments, Calhoun and his researchers created a series of "rat utopias" - enclosed spaces where rats were given ...

Mouse Heaven or Mouse Hell?
John Calhoun crouching inside Universe 25, his famous mouse-behavior experiment, February 1970. Officially, the colony was called the Mortality-Inhibiting Environment for Mice. Unofficially, it was called mouse heaven. Biologist John Calhoun built the colony at the National Institute of Mental Health in Maryland in 1968.
John B. Calhoun
John Bumpass Calhoun (May 11, 1917 - September 7, 1995) was an American ethologist and behavioral researcher noted for his studies of population density and its effects on behavior.He claimed that the bleak effects of overpopulation on rodents were a grim model for the future of the human race. During his studies, Calhoun coined the term "behavioral sink" to describe aberrant behaviors in ...
Tragedy in Mouse Utopia: An Ecological Commentary on Human Utopia
I had expected that this book would be mainly about the scientific experiment with the mice, and only secondarily about the implications for human society. It turns out to be mainly a political tract that leans on the mouse experiment to support its ideology. Read more. 9 people found this helpful.
CABINET / The Behavioral Sink
On day 560, a little more than eighteen months into the experiment, the population peaked at 2,200 mice and its growth ceased. A few mice survived past weaning until day six hundred, after which there were few pregnancies and no surviving young. As the population had ceased to regenerate itself, its path to extinction was clear.
World as Laboratory: Experiments with Mice, Mazes, and Men
That project turned into a larger investigation. Years of research into out-of-date sociological texts and in-depth archival work at foundations and government outposts eventually became the book World as Laboratory: Experiments with Mice, Mazes and Men. Next year I will begin a two-year fellowship at Harvard's History of Science Department.
The Universe 25 Experiment
Between the late 1960s and early 1970s, American ethologist John B. Calhoun created a seemingly perfect utopia for mice. Calhoun's predator-free, disease-free enclosure was furnished with limitless food and even an upper level with miniature mouse condos. Essentially, the mice would enjoy all the modern comforts people have come to expect today.
The Universe 25 Mouse Experiment
In 1972, John B. Calhoun built an utopia for mice. Every aspect of Universe 25, as this particular model was called, was designed to cater for the well-being...
How Mice Turned Their Private Paradise Into A Terrifying Dystopia
In 1972, animal behaviorist John Calhoun built a mouse paradise with beautiful buildings and limitless food. He introduced eight mice to the population. Two years later, the mice had created their ...
Calhoun's Rodent Utopia
Universe 25: Calhoun's Experiment with a Rodent Utopia. Expanding on his earlier studies, Calhoun devised his ultimate research experiment. In Universe 25, a population of mice would grow within a 2.7-square-meter enclosure consisting of four pens, 256 living compartments, and 16 burrows that led to food and water supplies.
Mouse Behavioral Testing
Methods to balance the order of tests and determine throughput are described, then a completely balanced order of tests in a complex experiment is presented. The book will be useful for those already familiar with the general principles of research but are new to the realm of behavioral testing of live mice.

Slit1 inhibits ovarian follicle development and female fertility in mice
The experiment was also performed using immature (22- to 25-day-old) Slit1-null (n = 5) and WT (n = 6) female mice stimulated with 5 IU (IP) of equine chorionic gonadotropin (eCG; Folligon, Merck) followed 48 h later by an ovulatory dose (5 IU, IP) of human chorionic gonadotropin (hCG; Chorulon, Merck). The mice were sacrificed 24 h afterward ...
