The relationship between boldness and reproductive success across the last 23 years.

a) Females Low SSTa years: = −0.60< SSTa <−0.36; b) Females Medium SSTa years: −0.36< SSTa <−0.15; c) Females High SSTa years: −0.15< SSTa <0.13; d) Males Low SSTa; e) Males Medium SSTa; f) Males High SSTa. Boldness, while being a continuous measure, is grouped here for plotting purposes only. As the raw data is formed of zeros and ones, plotting grouped means provides a much more informative plot. Points represent group means, with standard error bars. Model predictions are plotted in a solid line with 95% confidence intervals in dashed lines.
