APPLICATIONS OF THE EATER-FOOD MODEL TO PREDATOR-PREY-FOOD CYCLES POLISH JOURNAL OF ECOLOGY

ABSTRACT: This note gives five applica-tions of the eater-food interaction model (Gård-ing 2005) where cycle length is a function of the eater average birth rate defined as the inverse of average life span. The model extends to an analysis of predator-prey-food cycles (Gårding 2000). Here the cycle...

Description
Summary:ABSTRACT: This note gives five applica-tions of the eater-food interaction model (Gård-ing 2005) where cycle length is a function of the eater average birth rate defined as the inverse of average life span. The model extends to an analysis of predator-prey-food cycles (Gårding 2000). Here the cycle length is the same as that of en eater-food interaction whose average ’birth rate ’ is the sum of the average birth rates of the predator-prey and prey-food interactions. The model. In the eater-food interaction model the sizes E and F of eaters and food observed annually are predicted to be E + a (E − F) and F − E + B in the following year, B being a constant annual supply of food.
