The Food Hypothesis

The Food Hypothesis

(p.127) Chapter Eight The Food Hypothesis
Population Fluctuations in Rodents

Charles J. Krebs

University of Chicago Press

One of the first hypotheses suggested for the explanation of population fluctuations in rodents was the food hypothesis, which suggests that rodents simply run out of food when they reach peak numbers and then decline from starvation. This chapter discusses four variants of the food hypothesis and the observations needed to test teach. These variants are the food quantity hypothesis, the food quality hypothesis, the specific food resource hypothesis, and the food–habitat quality hypothesis. The chapter also illustrates the quantitative attempts carried out by small rodent ecologists to test the food hypotheses.
