WebbThe diversity was estimated using the Shannon (H0) index (H ¼ Sni/n ln(ni/n), where ni is the number of individuals in the taxon i and n is the total number of individuals). Values of the Shannon index usually are between 1.5 and 3.5, with 1.5 representing the lowest diversity and 3.5 the highest (Gazis and Chaverri, 2010).
