Males morphological and behavioral traits. Individual size, weight, and nuptial gifts obtained from the field and experimental trials performed after 12 weeks of feeding treatment using the two studied Paratrechalea ornata populations (Minas and Queguay). (I) Field data showing male size (A) and weight (B) (nMinas = 224, nQueguay = 164) and laboratory data showing the effects of prey availability (high and low) on male size (C) and weight (D) (nHigh Minas = 22, nLow Minas = 15, nHigh Queguay = 25, nLow Queguay = 19). (II) Field data showing nutritive and worthless nuptial gifts weight (E) (nMinas Nutritive = 59, nMinas Worthless = 40, nQueguay Nutritive = 3, nQueguay Worthless = 49) and laboratory data showing the effects of high (F) and low (G) prey availability on nuptial gift weight (nHigh Minas = 22, nLow Minas = 15, nHigh Queguay = 25, nLow Queguay = 19). In the boxplot, the black line represents the median; gray dots represent outliers. In (I), black dots represent the data points from Minas and red from Queguay; in (II), black dots represent the data points of nutritive and red of worthless gifts.
