Sentence examples for average richness from inspiring English sources

Average richness and farm uniqueness are complementary and reflect different aspects of biodiversity.

We considered several metrics of species diversity, but found two particularly useful at farm scale: average richness (area-weighted) and farm uniqueness in terms of species identity.

Across 1.86 ha of surveyed corridors, a total of 265 plant species and cultivars were present, with an average richness of 124 species per hectare.

We then calculated five resilience indices for our urban park and for a preserved continuous forest (reference area): the average richness of functions, diversity of functions, evenness of functions, and redundancy of functions within- and cross-scale.

Average richness reflects the expected species richness in a random sample taken on the farm, and farm uniqueness is the contribution of a farm to the total species richness of all farms under study.

The rarefaction curve represents the average richness of a treatment at a given number of sampled area.

At a genetic distance of 3%, the highest average bacterial richness according to Chao1 richness estimator was predicted for fertilized intensely managed grassland (2,887 OTUs), followed by fertilized mown pastures grazed by horse and cattle (2,720 OTUs), and unfertilized pastures grazed by sheep (2,226 OTUs).

Informative SNP had higher average allelic richness (AR = 1.82±0.22) and lower average private allelic richness (pAR = 0.024±0.049) compared with those in the poorly informative set (AR = 1.53±0.29; pAR = 0.092±0.075).

Rarefaction to 3.5 million reads per sample, where the gene identity of each read was retained, revealed an average gene richness of 353833 ± 29279 for guinea pig faecal microbiome, while the corresponding richness of 402831 ± 89613 genes per faecal sample found for humans was significantly higher (P = 0.037, Additional file 1: Figure S1).

Communities that evolved in random and clumped fractal (H = 1.0) landscapes attained nearly the same average species richness (random S = 22, fractal S = 20.5), but the range of variation in community species richness was 3× greater in random landscapes (random CV = 66%, fractal CV = 21%).

We did not observe more than 3 alleles per locus in NA, and average allelic richness was reduced by 76% when compared to the French population (Table 1), a higher reduction in allelic richness than found in any other introduced animal surveyed for that parameter [10].
