Currently, by compiling all the available metrics based on the previous literature, plus some new metrics developed in the present report, we made the calculation of these multiplesite beta-diversity statistics become ready for ecologists using R computing environment. An empirical study was present ...
1.Additive partition of diversity approach is used to analyzing the relative contribution of alpha diversity and beta diversity to gamma diversity of plant species in oak(Quercus liaotungensis) forest in a quadrat,slpoe positon,slope three scales hierarchical sampling system.利用物种多样性的加法分配法...
stem-mapped forest plots across the globe (Fig.1), we calculate total beta-diversity, the abundance-weighted species turnover component (hereafter species turnover), and the abundance
The ratio of the ion energy density of a plasma to its magnetic energy diversity, or of the particle pressure to the magnetic-field pressure. (science and technology) The second letter of the Greek alphabet; β, B. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © ...
Calculation of diversity indices We investigated the effects of alien tree species on native understory vegetation. We analyzed three aspects of native species diversity–taxonomic, phylo- genetic and functional at two levels—alpha (within- site) and beta (among sites). We quantified taxonomic alpha...
While a previous study in a similar habitat reported effects at 800 m, the number, size, and shape of habitat patches in the current study accounted for the diversity of the focal plots within 100–510 m. Furthermore, CART effectively screened 100 scales, revealing which landscape attributes ...
In both cases, one can dilute the diversity with corresponding segments encoding the sequence of the backbone protein in order to limit the average number of changes that are introduced. The term “recombination” is defined herein as a process wherein nucleic acids associate with each other in ...
The double-stranded oligonucleotides can be PCR products incorporating diversity in a specific region. In both cases, one can dilute the diversity with corresponding segments encoding the sequence of the backbone protein in order to limit the average number of changes that are introduced. The term...
Hello, recently, I tried calculating beta diversity using the skbio.diversity.beta_diversity. First, I hvae confirmed that the version of SciPy and scikit-bio is 1.14.1 and 0.6.2, repectively. Second, for the input table of skbio.diversi...
2.5. Calculation of species diversity indices We divided mainland China into 5,180 grid cells (50 km × 50 km resolution), as our focus was exploring large-scale determinants of the structure of biogeographic species assemblages (Menéndez-Guerrero et al., 2020). We built the ...
