Stable isotopes and estimates of isotopic niche area for Argentinean shortfin squid. Isotopic values were determined from the squid’s ovary. a, nitrogen isotope ratio distribution with maturation; b, carbon isotope ratio distribution with maturation; c Bayesian standard ellipse area (SEAb) estimates for each maturity stage. The grey solid circles and horizontal lines in the boxes indicating the means and medians; d Corrected standard ellipse area (SEAc) for each maturity stage with 40% Bayesian credible intervals. The boxplot horizontal line and grey solid point respectively denote the median and mean, while upper and lower hinges respectively represent the 25th and 75th percentiles. Maturity stage scale and sample size as presented in Fig. 2
