Temporal variation in ova and oocyte diameters.
Diameters (μm) of ova (red boxes) and oocytes (gold boxes) from female Diadema setosum from the GOA. Measurements conducted from January 2010 through February 2011. Boxes represent monthly average oocyte diameters; centre black lines show the medians; box limits indicate the 25th and 75th percentiles; the 95% confidence interval of each median is represented by the notches and is defined as ±1.58āĆāIQR/sqrt(n) (with n representing the number of samples as indicated under the boxes); whiskers extend to minimum and maximum values with open circles representing outliers; width of the boxes is proportional to the square root of the sample size.
