Figure 4

Smoothers of the effect of the three non-parametric terms: time, Southern Oscillation Index (SOI), chlorophyll and Southern Annular Mode (SAM), on the gonad index of Sterechinus neumayeri, from the optimal GAM model. Shaded area represents a 95% confidence interval and data points represent raw gonad index data. The magnitude of change in gonad index as a response to the change in the x-variable is represented on the y-axis as the square-root transformed gonad index. For the axis ‘time’, year intervals are plotted on every 1st January. Green represents males and yellow represents females.
