The paramecium species competed for the same limiting factors because they shared the same niches. This increased the competition between the species and caused both populations to decrease.

(Note: in Gause’s experiment P. aurelia ultimately outcompeted P. caudatum, driving P. caudatum to extinction — an example of the competitive exclusion principle.)
