John B. Calhoun (ethologist)

John B. Calhoun was a pioneering ethologist known for studying how rats and mice behave in densely populated environments. His experiments showed that overpopulation can lead to social disorder, stress, and a breakdown in typical social interactions, often resulting in population decline. These findings provided insights into the effects of crowded living conditions on social behavior, highlighting potential parallels to human societies. Calhoun’s work underscores the importance of social environment on individual well-being and community stability.
