Dynamics of the number of native and invasive species, taxonomic diversity (Shannon’s diversity) and six functional diversity indices (FDiv, FDis, FRic, FEve, FRAO and FRed) computed with weekly data on the fish captured by fyke nets in Minho Estuary (Portugal) from 2010 and 2019. Blue lines refer to a simple moving regression (loess) and are only indicative of the temporal changes. Statistical tests can be found in Table 4. FDiv = functional divergence, FDis = functional dispersion, FRic = functional richness, FEve = functional evenness, FRAO = Rao’s quadratic entropy and FRed = functional redundancy.
