  "Description": "A collection of measures for measuring ecological\ndiversity. Ecological diversity comes in two flavors: alpha\ndiversity measures the diversity within a single site or\nsample, and beta diversity measures the diversity across two\nsites or samples. This package overlaps considerably with other\nR packages such as 'vegan', 'gUniFrac', 'betapart', and\n'fossil'. We also include a wide range of functions that are\nimplemented in software outside the R ecosystem, such as\n'scipy', 'Mothur', and 'scikit-bio'.  The implementations here\nare designed to be basic and clear to the reader.",
