The paper describes rich, a new R package to perform species richness estimation and comparison. Species richness is the simplest surrogate for the more complex concept of species biodiversity. It is relatively easy to assess although estimations strongly depend on sampling intensity with the ...
(Because most of those studies only used the Richness and Shannon index, for comparison purposes, we showed the results of Richness and Shannon index only.) Commonly used species diversity indices can only represent one or several “points” of the whole diversity continuum and lack continuous mea...
However, we have little understanding of how environmental heterogeneity shapes the effect of diversity on ecosystem functioning and to what extent this diversity effect is mediated by variation in species richness or species turnover. This knowledge is crucial to scaling up the results of experiments...

These findings suggest that especially the inclusion of interannual climate variability has a large potential of improving the estimation of niche characteristics across a broad range of taxa, and especially narrow range species. Including temporal predictor variability increased the performance of SDMs in...
species richness and think ofCias denoting the species counted at time or place i (the same reasoning also extends to the problem of abundance estimation). The relationship between the quantity of interest (Ni= the number of species in the sampled community) and the actual count (Ci) can be...
To understand how diversity is distributed in space is a fundamental aim for optimizing future species and community conservation. We examined in parallel species richness and beta diversity components of nine taxonomic groups along a finite space, repre
An asymptotic analysis: comparison of the estimated asymptotic diversities. It is based on statistical estimation of Hill numbers via three functions: ChaoRichness(), ChaoShannon() and ChaoSimpson(); these functions return, respectively, the estimated asymptote for Hill numbers of order q = 0, 1...
