Table 2 Linear model results of the time series analysis of DDG
variables (Dmax and Rmax) across
richness components for each lake. Here, +: positive slope of linear
model (Meaning for Dmax: becomes shallower; Meaning for
Rmax: more species); −: negative slope of linear model
(Meaning for Dmax: becomes deeper; Meaning for
Rmax : less species); significance levels of p-values: 0
