Body condition and stress and breeding parameters of adult Magellanic penguins breeding in the three erosion zones (High, medium and low) at Martillo Island.

Mean and SD (standard deviation) of body condition (adults body index), heterophyl vs. lymphocyte ratio (H/L), weight and body index of fledging, and breeding success are shown. Estimated coefficients (Est.), standard errors (se), t-values (with 21 degrees of freedom) and p-values (p) for specific comparisons of H/L between stages and between different degree zones, obtained from GLMM (to F see text) and z value from GLM with Poisson distribution order body condition over breeding success. ANOVA (F, with 2 freedom degree), Kruskal-Wallis (H with 2 freedom degree) statistics and their correspondent p-value. Significant differences are marked in bold. N number of birds (or nest for breeding success).
