R alpha beta diversity
WebbR is an open source (free) statistical programming and graphing language that includes tools for analysis of statistical, ecological diversity and community data, among many other things. R provides a cohesive environment to analyze data using modular “toolboxes” called R packages. Webbscaling of beta diversity have not yet been thoroughly explored. There are two main approaches that can be used to concep-tualize spatial variation in beta diversity: (i) the distance-decay of community similarity, and (ii) the partitioning of species diversity into alpha and beta components.

WebbSpecies diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant). ). … WebbBeta diversity shows the different between microbial communities from different environments.
