The ratio between the observed species richness and the estimated species richness measures the completeness of inventories in each surveyed cell.
Of course, without the immediacy and completeness of store inventories, you really needed to "look" hard.
In order to standardize the analyses, we evaluated the degree of completeness of the inventories for each site as the percentage of observed species with respect to the number of species predicted by Chao1, a nonparametric estimator of species richness based on species abundance that takes the rare species in the sample (≤2 individuals) into account [36].
To compare sampling design efficiencies, the degree of completeness of collected annual inventories was estimated, along with an "optimal sampling" selection of months, i.e. the minimum number of months indicating most accurately the number of species present throughout the year.
The completeness of our taxonomic inventories ranged from ∼55 100%, and varied by sub-region and faunal type (Table 13).
Hybrid LCA has been identified as the best model in improving the completeness of EE and EC inventory data.
We reanalyzed the flanking sequences of these gaps and identified fragments orthologous to HoxB13 (exon2) and HoxD9 (exon1), improving the completeness of lizards' Hox gene inventory.
The results revealed that the hybrid LCA improved the completeness of the EE and EC inventory data compared with other models.
We further use the results obtained in the Collazzone area to estimate the quality and completeness of the two regional landslide inventory maps, and to outline general advantages and limitations of the techniques used to complete the inventories.
Effectiveness was measured in three ways: the number of inventory elements captured at least once by the plan (representation), the total number of inventory elements captured (completeness), and the proportion of land in the inventory-based plan included (overlap).
