Im using R to calculate beta diversity values between pairs of samples. The effect of environmental gradient on biodiversity and similarity of invertebrate communities in eelgrass () beds. Note that despite the similar values of total dissimilarity (βSOR) in southern and northern Europe, turnover (βSIM) is much higher in the south and nestedness‐resultant dissimilarity (βSNE) is much higher in the north. This data set consists of data on the occurrence of grassland plants at several different sites in Alberta, along with information on their functional traits and phylogenetic relationships.

Metrics of structural change as indicators of chironomid community stability in high latitude lakes. (2005) have recently reviewed two major approaches to analysing and modelling patterns in beta diversity: (1) the ‘raw‐data’ approach, in which various environmental and geographical components of beta diversity are partitioned through some form of canonical analysis (e.g. As seen above, multiplicative beta diversity (gamma/alpha) ranges from 1 to N (number of sites in the region). Ground‐dwelling mammal diversity responds positively to productivity and habitat heterogeneity in a fire‐prone region. The beta diversity measures used here follow the partitioning framework independently developed by Podani & Schmera (2011) and Carvalho et al. Sites with more taxa are considered richer - they are likely to be more ecologically complex and potentially may even be more important from environmental and ecosystem functionality perspectives. (2012) A few also incorporate phylogenetic relatedness and require a phylogenetic tree of the organisms in either community to be calculated.

The content of the page looks as follows: Example 1: Beta Density in R (dbeta Function) Example 2: Beta Distribution Function (pbeta Function) Example 3: Beta Quantile Function (qbeta Function) (2014), where Btotal = Brepl + Brich. Brepl = beta diversity explained by replacement of species alone; Brich = beta diversity explained by species loss/gain (richness differences) alone.
