Sentence examples for richness accumulation from inspiring English sources

We used the Mao Tau function to calculate observed richness (accumulation curves) and the Chao2 function to calculate estimated richness.

The observed species richness dependent pattern of low functional diversity indicates that communities with low species richness accumulate functional traits randomly, whereas species in species-rich communities are more similar to each other than predicted by random assemblages and therefore exhibit an accumulation of stream-specific functional traits.

The fact that these parameters can be varied, allows for a close quantitative fit between model and observed communities to be achieved, particularly with respect to annual species richness and species accumulation through time.

Through an analysis of observed species richness and complementarity, accumulation curves, and richness estimators, we conduct an a posteriori analysis of five bioblitz-style collection strategies that differed in terms of total duration, number of sites, protocol flexibility to heterogeneous habitats, sorting of specimens for analysis, and primary purpose of collection.

We produce species richness maps and species accumulation curves that are corrected for imperfect species detection, and we study patterns of beta-diversity (turnover among sites) by comparing sites in terms of occurring species using a Jaccard index.

While this discrepancy may be due to differences in sampling depth or location between the CPR and fixed-station sampling programs, we believe that the higher species richness observed in species accumulation curves at the eastern stations is due to the transient appearance of offshore or cold-water species on the Scotian Shelf and in the Bay of Fundy.

To accommodate differing sample sizes, we compared provisional species richness among strategies using accumulation curves for successfully barcoded individuals.

We then calculated the accumulation of species richness along each sequence and, based on the 100 realizations, the mean accumulation of species richness per farm.

Both observed and estimated by accumulation curves, species richness values of these different cell groups were subsequently used as the dependent variable in the modelling procedure.

This functional approach provides a counter-point to an assumption that lichen epiphyte communities are unsaturated and non-competitive, a situation which would allow the long-term accumulation of species richness with temporal continuity.

Still, his account achieves both intimacy and vibrancy because of the richness of its layering, its nonstop accumulation of analyzed detail.
