The total number of wintering birds (Figure 2a ) showed a decreasing trend ( Z = −1.9, p = .04).
The total number of wintering birds (Figure 2a ) showed a decreasing trend ( Z = −1.9, p = .04).
The mean annual temperature (Figure 3a ) showed a slightly increasing trend over the studied period ( Z = 1.0, p = .09).
Based on this analysis, positive values of Z indicate an increasing trend, while negative Z values indicate decreasing trends in the time series.
