Sentence examples for variance of populations from inspiring English sources

A critical insight was that diversity may increase variance of populations, but it decreases the temporal variance of ecosystem properties (a metric of ecosystem stability) [ 22].

According to the empirical regularity called Taylor's law, the variance of population density in samples of populations is a power of the mean population density.

We suggest the use of a method called "delete-a-group" jackknife to estimate the variance of population attributable risk when a complex survey design has been implemented.

In this instance, the lower genetic diversity of WT compared to MutS is associated with a lower rate of increase in the variance of population size.

In practice, some auxiliary information can often be obtained, such as that the unknown distribution is symmetric or the variance of population is a function of the mean.

In 2004, 13 years after population management actions were implemented, the variance of population wide FA was comparable to the FA-variance from the beginning of the 20th century.

Taylor's power law describes an empirical relationship between the mean and variance of population densities in field data, in which the variance varies as a power, b, of the mean.

Showing that a power law applies to relationships between the mean and variance of population size suggests orderly underlying processes (Taylor et al. 1983, but see, e.g., Hanski 1982; Anderson et al. 1982).

Increased sample sizes would have resulted in better estimates, especially for the variance of population differentiation (S2FST).

Mean and variance of population fitness estimated excluding extinct lines are presented in a supplementary fig. S1 (Additional file 1: Population mean fitness and variance with bottlenecks).

For each of the 9000 points in parameter space, we compared field (census) estimates of annual mean and variance of population size to annual mean and variance of simulated population size.
