Dr John B. Calhoun conducted a series of experiments in the 1960's on the effect of over-population on Norway rats.

Wikipedia explains:

The conclusions drawn from this experiment were that when all available space is taken and all social roles filled, competition and the stresses experienced by the individuals will result in a total breakdown in complex social behaviors, ultimately resulting in the demise of the population.

His own paper describes infant mortalities of 80% or 96% depending on the experiment.

Have these results been replicated? Are they considered solid science by today’s experts?

    Its seems pretty likely to be true, I would be more surprised if the opposite case was made. – Mark Rogers Apr 3 '16 at 21:14
