However, contrary to most previous work, we also find no support for the hypotheses that high species richness is correlated with small body size and fast life history. Rather, high species diversity is strongly associated with pronounced plumage dichromatism, generalist feeding habits and good ...
Additionally, species-level models of common taxa adequately predict overall species richness. Conclusions: Understanding the bulk of the diversity around us is imperative during an era of biodiversity change. We show that dark insect taxa can be efficiently characterised and surveyed with megabarcoding...

We estimated the relative abundance of each microbial species in a sample using the formula as below. We first calculated the average read coverage of all 2bRAD markers for each species, which represent the number of individuals belonging to a species present in a sample at a given sequencing ...
Species richness, evenness, and diversity are all fun concepts to teach biology students. I like them because they are somewhat intuitive, easy to calculate, and can be used to compare different populations. Species richness is simply the number of species present in an area. Species evenness ...
breve abundance in FT-1, which had a 33% decrease in species richness, increased from ~6% to ~36% (Fig. 3a, d and Supplementary Fig. 5; Supplementary Table 2). Such a community structure remained mostly unchanged when growing the FT-1 community in media supplemented with 2’FL ...
We then estimated (uncorrected) species richness, Su, from each of the samples by fitting Fisher’s α to the sampled data and applying the formula \({S}_{u}=\alpha \times {\rm{ln}}\left(1+\frac{N}{\alpha }\right)\). From each of the samples we also derived continental-scale ...
Accordingly, these zones differ not only in their plant composition, but also in diversity, richness and density, which increases towards tree-dominated climax vegetation (Supplementary Table 1). A large part of this aboveground biodiversity is threatened3,7, mainly due to the increase in ...

The purpose of our study was to test the assumption that the relationship between the degree of numerical dominance (DD) and local species richness may differ in plant communities with high and low interspecies competition intensity. The stands and open communities of the river shoals of the ...
