Calculating Population Size
Populations of any organism can be analyzed mathematically. Population biologists are interested in
characteristics such as doubling time, growth rate, carrying capacity, and total population at the end of a
given amount of time.
Use the following formulas to calculate doubling time of a population when there is no environmental
resistance and total population when environmental resistance limits growth.
70
Doubling time
% growth rate
Total population (when there is environmental resistance)=n+rn ()
Where n= initial population size
r= growth rate (expressed as a decimal)
K= carrying capacity
