Regulation of a Northern Grey Squirrel (Sciurus Carolinensis) Population
1978
Thompson, Donald C.
The parameters of a northern grey squirrel (Sciurus carolinensis) population were examined. The objective was to determine the factor(s) that controlled population size. Adult death rates were constant and were less than those of young. More young produced that subsequently entered the breeding population. The number of young recruited into the adult population was the main parameter which determined population size. The dispersal of young was the factor that determined the number of young which survived to recruit. The essential conclusion is that established squirrels interact with young to regulated recruitment through dispersal, and, in turn, population numbers.
