beta_diss(x, index.family = "sorensen")
beta_core returns an object of class beta_diss like the betapart.core function. This object can be called by beta.pair or beta.multi.

beta_diss returns a list with three dissimilarity matrices. See beta.pair for details.
an object of class Matrix, where rows are sites and columns are species.
