Reproductive energy relation to nitrogen stable isotope ratio and selected fatty acids for Argentinean shortfin squid. Isotopic values and fatty acid profiles were determined from the ovary of Argentinean shortfin squid. Relationships between reproductive energy and nitrogen isotope ratio (a), relative amounts of 14:0 (b), 18:0 (c) and 20:4n6 (d). Estimate in the top-left corner depicts average fixed-effects exponent value; blue lines depict average model fits, with 95% confidence intervals in grey shading
