Sentence examples for estimate of richness from inspiring English sources

In the setting of equal probability of distribution and sampling of types, the Chao1 estimator yield a point estimate of richness.

Chao1 estimates were derived as a lower-bound estimate of richness, whereas ACE better approximates a point estimate of richness [36].

The approach that was taken while unable to provide an estimate of richness for 16S rRNA based OTUs as conventionally defined (ie: at a 3% dissimilarity cutoff), nonetheless provides insight to the underlying form of the community distribution.

We used an incidence-based nonparametric estimator by comparing the presence or absence of particular sequences in replicate samples and calculated an estimate of richness in healthy young adults that is at least one order of magnitude higher than previously published numbers obtained using parametric models [ 8].

All seven non-parametric species richness estimators provided higher estimates of richness for both designs (mean = 5.4 ± 3.8 species), but only four of the richness estimators reduced differences in richness obtained by the two designs to a non-significant level (p ≥ 0.05) across the sites.

Non-parametric statistical estimates of richness, Chao1 and Abundance-based Coverage Estimator (ACE), and 95% confidence intervals were calculated using EstimateS 8.0 [33].

PHACCS estimates of richness the average genome size calculated by GAAS 0.15 and a contig spectrum generated by Circonspect 0.2.4 (10× coverage), using the Minimo assembler and default parameters.

Despite these conditions, it is clear that deep-sea habitats harbour high species diversity; estimates of richness frequently exceed 1 million species globally [7] [10].

Chao1 estimates of richness were only slightly higher (39 and 57.2 species in the invaded and non-invaded areas respectively) than observed numbers of species suggesting that our sampling captured most ant species possible given the methods used.

Consistent with this observation, the Chao1 estimates of richness were substantially higher (39% 105%) than the observed number of OTUs as shown in Table 2. On average, observed bacterial richness was highest in the red colobus, followed by red-tailed guenon, and black-and-white colobus, though each subject showed variable numbers of OTUs.

The lowest estimates of richness (53 and 58) were estimated for the biofilter.
