Taxonomic diversity metrics
Species richness and cover were averaged across the 6 seasonal subplots
in each site. Species evenness was obtained by using the Inverse Simpson
index (considered as “simpson”) in the adiv package (Pavoine, 2020).
The index is as follows: \((1/\sum jp2ij)/Si\), where Si is
the number of species in a community, \(p\text{ij}\)is the relative
abundance of species \(j\) in community \(i\). This index was selected
due to its high sensitivity to both dominant and rare species with
symmetry between them (Smith & Wilson, 1996; Beisel et al. 2003).
