Unveiling the species-rank abundance distribution by generalizing the Good-Turing sample coverage theory Based on a sample of individuals, we focus on inferring the vector of species relative abundance of an entire assemblage and propose a novel estimator of t... Anne,Chao - 《Ecology》 被引量:...
Initially, values of Fisher’s α were fitted to the empirical species abundance vectors from each region using maximum likelihood and numerical optimization in the ‘sads’ R package70 and fits visualized with Preston plots71 and rank abundance distributions (RAD)36 (Extended Data Fig. 4). ...
The rank-abundance curve described a lognormal distribution pattern, indicating high diversity communities. The species diversity indices obtained were high: Fisher's alpha diversity index ranged from 96.53 to 109.56, Shannon-Weiner index were 5.29 to 5.39, while values of Simpson Index ranged from ...

(e.g., examining the rank abundance of the most highly expressed genes can form the basis for new testable hypotheses [25]). Analysis methods presented below in addressing batch effects may be beneficial. An alternative or compliment to saturation plots involves plotting the number of new genes...
However, we were able to assign the species rank Acanthopagrus schlegelii to this OTU because A. schlegelii is the only species from the genus Acanthopagrus in Maizuru Bay. (2) When assigned species were unlikely to occur in Maizuru Bay, we suspected an incorrect assignment because the ...
For example, parametric approaches assume a particular species abundance distribution (such as the log-normal or gamma) or a species rank abundance distribution (such as the negative binomial or log series), and then estimate parameters from the distribution model that quantify the heterogeneity among...
