The “zetadiv” R package, which contains functions to compute compositional turnover using zeta-diversity, the number of species shared by multiple assemblages, is now available onCRAN (http://cran.r-project.org/web/packages/zetadiv/).
The package includes a Zeta.order() function to compute zeta-diversity for a specific number of assemblages, and a Zeta.decline() function to compute zeta-diversity for a range of numbers of assemblages.
It also includes additional functions to explain how zeta-diversity varies with distance and with differences of environ- mental variables between assemblages, using linear regressions and generalized additive models.
