Several examples are given to illustrate the dangers of inferring the existence of density—dependent population regulation on the basis of correlation analyses. Alternate models based on a series of random number (or random selections from some other frequency distribution) have expected correlation coefficients very close to those cited as demonstrating density dependence. A "Morris plot" can also be generated from a series of random numbers.
