Sentence examples for biological richness based on from inspiring English sources

We recently developed a statistical procedure to estimate biological richness based on observed data of this type, and tested it on both prokaryotic and protistan datasets [22], [25].

When the decline of zeta diversity follows the negative exponential form, the zeta-based richness estimator becomes the same as the incidence-based Chao II estimator which estimates richness based on the frequency of singletons and doubletons in samples.

We also used an incident-based methodology that specifically calculates species richness based on presence-absence and not density of species [ 12, 13].

First, we use an estimate of functional richness based on dendrogram length, FRD [8].

As expected, predictions of protistan richness based on single PCR primer datasets were lower than those based on pooled clone data (Table 1).

Given that FRD has been found to be strongly correlated with species richness [11], we choose a second estimate of functional richness based on the volume of a multidimensional functional space, FRV, measured as a convex hull volume [10].

While the residuals from the relationship between true richness and predicted richness based on habitat suitability in these sites were not spatially auto-correlated (Figure S1), the co-occurrence test results remained the same.

Manning & Bucklin [40] observed a similar annual cycle in copepod species richness, based on net-collected samples in the western Gulf.

In addition to predicting the DI protistan richness based on pooled clone data (Table 1), we conducted separate analyses using rRNA gene sequences obtained with individual PCR primers.

Potential species richness based on available native records only of 39 invasive cactus species.

The structural biodiversity component encompasses species richness based on morphological or molecular characteristics and their relative abundance.
