Oct 28, 2013 · Abstract. In the 1960s–1980s, determination of bacterial growth rates was an important tool in microbial genetics, biochemistry, molecular biology, and microbial physiology. The exciting technical developments of the 1990s and the 2000s eclipsed that tool; as a result, many investigators today lack experience with growth rate measurements.
The growth rate of a population is largely determined by subtracting the death rate, D, (number organisms that die during an interval) from the birth rate, B, (number organisms that are born during an interval). The growth rate can be expressed in a simple equation that combines the birth and death rates into a single factor: r.

AboutTranscript. Population growth rate represents the net increase in population based on birth and death rates. Per capita population growth rate measures the average growth rate per individual. Exponential growth equations describe unconstrained population growth, while environmental carrying capacity sets real-world limits.

We can use our knowledge of exponential population growth and our value of R 0 to estimate the intrinsic rate of increase (r) (Gotelli 2001). The size of an exponentially growing population at some arbitrary time t is N t = N 0 ert , where e is the base of the natural logarithms and r is the intrinsic rate of increase.
