Using a numerical simulation, the likelihood of encountering landscapes with an opposite response was demonstrated to increase with increasing richness, from about 4% for landscapes consisting of three cover types, to about 6% for ten types.
In plant communities, the accumulation of specialists is paralleled by a reduction in the individual species biomass with increasing richness, which follows from the partitioning of total biomass among species per unit area.
In shallow waters (under 50 m), there is some evidence of depressed biodiversity among epifaunal and infaunal organisms in the shallowest areas, and increasing richness with depth thereafter (Figure 3b).
Regardless, the finding of increased richness with increased forest size confirms prior observations in related diversity studies.
PhyloChip and pyrosequencing communities showed significantly increased richness with time, but not with lignin amendment (Table 1, Figure S6).
In sites with lower functional richness (<4.5 functional groups per panel) convergence rates decreased with increasing taxon richness (significantly so as suggested by the confidence intervals in Fig. 2), while in sites with higher functional richness (≥4.5 functional groups per panel) convergence tended to accelerate with taxon richness.
Indeed, the slope of the regression between convergence rate and taxon richness increased from negative ("enhancing persistence") to positive ("reducing persistence") with increasing functional richness of the experimental sites (Fig. 1, Spearman rank correlation, n = 16, r = 0.54, p = 0.03).
In fact, overlooking the allelic richness effect in our experiment, would also suggest enhanced resistance with increasing genotypic richness similar to reports from previous studies [ 50, 51, 57].
Though he still has youthful sweetness in his voice, in recent years he has been singing with increasing ardor, richness and power.
Succession continued after 5 years, with increasing species richness, perennials and species characteristic of non-arable habitats.
Temporal synchronization across studied variables was mostly unaffected with increasing species richness.
