Sentence examples for variance in populations from inspiring English sources

Quantitative genetic models have provided an analytical framework for partitioning the observed phenotypic variance in populations into components attributable to these various sources.

Analogously, maintenance of outcrossing versus selfing may be due to increased fitness variance in populations with higher outcrossing rates [ 12, 13].

Although stochastic factors influence variance in population abundance of less aggressive taxa, demographic constraints due to host resistance strongly regulate their populations near a low abundance equilibrium.

Genetic architecture interacting with the rate of environmental change accounts for 78% of the variance in trait heritability and 66% of the variance in population persistence times.

Network size and topology, the width of the fitness function, pre-change additive variance, and certain interactions account for ∼75% of the variance in population recovery times after a sudden environmental change.

The variance in population estimates further exacerbates the uncertainty in defining projections further into the future.

Mean and variance in population fitness were measured in the ancestral population and in the MA population replicates every two bottlenecks until extinction of all lines.

While environmental stochasticity tends to inflate the variance in population size and demographic rates, negative density feedback at high population sizes has the opposite effect [ 2, 4].

We found that the interaction between delayed breeding, density-dependence, and demographic stochasticity accounts for 33 to 49% of the variance in population size.

Variance in population selfing estimates was best explained by the additive effects of the four variables marg, exp, lim and size (Akaike weight 0.97).

Furthermore, with the increased incidence of EP, and variance in population structure and regional differences, the risk factors of EP may have changed.
