Hypothesis 1: Decreasing salinity promotes rotifers and
cladocerans
We expected the share of rotifers and cladocerans to be negatively
affected by salinity (Gutierrez et al. 2018). To find support for
H1, we looked for expected links between the interannual variations in
community composition: the average position along the axis A2 that
corresponded to the complexity, or relative share of rotifers and
cladocerans in summer as a function of annual mean salinity in the study
area.
