Sentence examples for population richness from inspiring English sources

There are several ways of measuring the diversity of a viral population: richness, evenness, Rao's entropy [33], Shannon entropy, other Renyi entropies, etc.

The statistical challenges for microbiome studies are to estimate population richness and diversity, model community structure, quantify uncertainty and compare estimates rigorously [ 50].

The microbial community in this well-performing digester was distinguished by high abundance and high population richness of M. bourgensis, emphasising the importance of this methanogenic group for successful operation in high-ammonia, mesophilic conditions.

Taking into consideration the metadata we did not find any significant differences in ecological measurements of microbial diversity or population richness (rarefaction, ace, Chao1) we did notice a significant difference in ulcers associated with their community composition in relation to whether the patient had diabetes or not.

It indicated that diversity (population levels, richness, diversity, evenness, trophic and colonizer/persister groups) does not differ between the communities sampled.

This shows that while the population species richness may be high, evenness is low and a few species dominate.

The total number of alleles estimated for 5 individuals per population (allelic richness, FSTAT 2.9.3) [ 30] ranged from 17.16 to 24.85, showing little variation between populations.

Mean population allelic richness was significantly negatively related to distance from PNG, with distance explaining 75% of the variation in allelic-richness differences between sites (Adj R = 0.75, F1, 29 = 91.57, P < 0.001; Fig. 3A).

We then analysed the relationship between Pielou's evenness index and (a) population allelic richness and (b) observed heterozygosity to test the prediction that populations with more admixture should also carry more genetic diversity.

A common subset of 25,340 SNPs with MAF ≥ 0.2 in all tested pigs were explored to calculate three measures of genetic variability of each population: allelic richness (AR), the proportion of polymorphic markers (PN) and expected heterozygosity (HE) using ADZE [ 44] and PLINK [ 45] as described previously [ 19].

For these experiments, ending community populations, species richness, Shannon diversity, and Simpson diversity were clearly different for the different topologies, but the relationship between the topologies varied as the dispersal rate changed.
