Sentence examples for variability in population from inspiring English sources

A linear relation between log variance and log mean (Taylor's law) described accurately and robustly how variability in population size changed with mean population size in P. fluorescens bacteria.

Fourth, a model-assisted approach may lend itself to use of the GAM, balancing the variability in population-level estimation with more conservative inference that takes advantage of the design-based properties of the sample (Opsomer et al. 2007; Næsset et al. 2016).
