This model seeks to explain stand productivity P as a function of species richness R, the stand structural heterogeneity expressed by the diameters' coefficient of variation, CVd, stand density, SDI, mean tree size, represented by mean tree diameter, dq, mean annual temperature and annual precipitation.
To do this, we used a second general linear model in which we analyzed total algal biomass as a function of species richness (1 vs. 5 species), nutrient treatment (homo- vs. heterogeneous), and the two-way interaction.
Although studies have routinely found that the production of biomass tends to increase as a function of species richness, and this is true for a wide variety of organisms [11], [12], it is commonly observed that the biomass of diverse communities is seldom higher than that of the most productive species in monoculture [15], [16], [52].
(F ) The percentage of expected number of cleavage sites within the 16 CDEII sequences, comprising a median of 83 bp, and that of the 46 sequences ≥90% A+T are plotted as a function of AT-richness.
To evaluate warming effects on functionality (MF), we applied a power law function MF = cOR α, where MF is functional redundancy, OR is orthologue number as a function of rarefied OTUs richness, α is a functional redundancy index with lower values indicating larger functional redundancy (Wilhelm et al. 2015).
The non-parametric richness estimator, Chao1 [ 49] was determined to predict the total richness of the miRNA population, as a function of the observed richness (S obs ), the number of sequences observed only once (singletons, n 1 ) and the number of sequences observed twice (doubletons, n 2 ).
H' increases as a function of both the richness and evenness of cultural variants.
Algal biomass density averaged across all nutrient patches (i.e. the biomass density of an experimental unit) generally increased as a function of algal species richness (Table 1, Figure 3).
We recorded the community composition of each taxon at multiple sites and modelled species richness as a function of seven environmental predictors.
Rarefaction analysis is commonly used in ecological research defining species richness as a function of sequencing effort.
