Mean density (box-plots) and percentage of occurrence (■) of Pyrenean sculpin Cottus hispaniolensis in the sampling sites from 2001 to 2016. Due to unequal sampling effort among years, data is pooled in several time groups. In box-plot, filled circle is the mean and solid horizontal line is the median. Upper and lower box limits are the 25th and 75th percentiles, and bars represent the 5th and 95th percentiles. The spate of June 2013 is represented as a dashed vertical line.
