A rank abundance curve or Whittaker plot is a chart used by ecologists to display relative species abundance, a component of biodiversity. It can also be used to visualize species richness and species evenness. It overcomes the shortcomings of biodiversity indices that cannot display the relative role different … See more The rank abundance curve visually depicts both species richness and species evenness. Species richness can be viewed as the number of different species on the chart i.e., how many species were ranked. Species … See more Quantitative comparison of rank abundance curves of different communities can be done using RADanalysis package in R. This package uses the max rank … See more • Whittaker Diagram, Procedural Content Generation Wiki - use of Whittaker diagrams in procedural content generation • RADanalysis package in R, Package in CRAN contain functions for quantitative comparison of rank abundance curves See more Web2 days ago · Abstract—The microbial diversity and community structure of activated sludge in the biological treatment units of five municipal WWTPs and two industrial WWTPs were studied. The results showed that industrial WWTPs had the lowest diversity and abundance of activated sludge microbial communities, indicating that industrial wastewater inhibited …
