However, they differed greatly in terms of their activity levels. Two distinct types of males emerged, each having withdrawn completely from the struggle for dominance. In the experiments in which the behavioural sink developed, infant mortality ran as high as 96 percent among the most disoriented groups in the population. Individual rats seldom ate alone, leading to a proliferation of population density within the pen designated for feeding, while the others remained sparsely populated. During feeding periods, up to 60 out of 80 rats in each experimental population would gather in a single pen. The root cause of these disturbances became strikingly evident in the initial series of three experiments, wherein we observed the emergence of what was termed a 'behavioural sink.' The rats would congregate in large numbers within one of the four interconnected pens that housed the colony. The disruption extended to the social organization of the animals. These individuals would only emerge to eat, drink, and move about when the rest of the community was asleep. Among the male rats, their behavioural disruptions encompassed sexual deviation, cannibalism, frenetic overactivity, and a pathological withdrawal.
