Table 2 GLMM results testing for differences in the taxonomic alpha diversity (TD) of large epifauna (> 0.5 mm), small epifauna (< 0.5 mm) and infauna among zones in the seagrass patch as a function of fragmentation level (two-way interaction, ‘zone \(\times\) fragmentation’), for each ‘q’ parameter: ‘q’ = 0 (i.e., species composition only, analogous to species richness), ‘q’ = 1 (i.e. weighted in proportion to species abundances, analogous to Shannon entropy), and ‘q’ = 2 (i.e. more weight on very abundant species, analogous to inverse Simpson index).
