Beta diversity refers to changes in community composition across time and space, including species richness and replacement. Few studies have examined beta diversity patterns of riparian vegetation communities in terms of taxonomic, phylogenetic and functional attributes. In this study, we conducted a ...
Beta diversity Also called species turnover, beta diversity refers to the change in species as one moves across habitats, communities, or ecosystems. Divergence-with-gene-flow model of speciation A model explaining the process of species formation (speciation) in which new species diverge in the ...

Beta diversity measures the change in diversity of species from one environment to another. In simpler terms, it calculates the number of species that are not the same in two different environments. There are also indices which measure beta diversity on a normalized scale, usually from zero to ...
The amount of reactivity of a nuclear reactor corresponding to the delayed neutron fraction. (plasma physics) 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. ...
Beta diversity, which is assumed to bridge local alpha diversity to regional gamma diversity was partitioned into the two components turnover and nestedness and analyzed at two levels: from the lowest elevation to all other elevations, and between neighboring elevations. Species richness of vascular ...
Diversity of beta-lactam resistance levels among related Klebsiella pneumoniae strains isolated in an intensive care unit. Seven multiresistant Klebsiella pneumoniae strains isolated in an intensive care unit were studied. Susceptibility to beta-lactams was determined with the ... Paniara,Platsouka,Dimo...
The diversity of an TCR repertoire can be estimated by the richness of the repertoire, i.e., the number of unique clonotypes present. Note that the diversity depends on sequencing depth. b. Clonality. The clonality of a TCR repertoire attempts to determine the distribution of clones in terms...

According to this system TNV has been designated as genotype V [63], [67]. It has been suggested that genetic diversity among Betanodavirus strains reflects significant phenotypic differences, which may represent adaptation enabling infection of different host species and/or replication at different ...
