Mating, fecundity and paternity success of males offering worthless gifts. Double matings performed in a window period of 24 h in the two studied Paratrechalea ornata populations (Minas and Queguay). All females’ first matings involved males offering a worthless gift (nMinas = 23, nQueguay = 20), whereas second matings were either with males offering a nutritive (nMinas = 14, nQueguay = 10) or a worthless gift (nMinas = 9, nQueguay = 10). (I) Effects of gift type and mating order on mating duration (A) and number of pedipalp insertions (B). (II) Effects of group (worthless-nutritive, worthless-worthless) on fecundity (C), number of spiderlings (D), and hatching success (E). (III) Effects of male size on paternity success (F). In the boxplot, the black line represents the median; gray dots represent the outliers. In (I), black dots represent the data points of nutritive and red dots of worthless gifts; in (II), black dots the represent data points of the worthless-nutritive group and red dots of the worthless-worthless group; in (III), black dots represent the data points of zero paternity and red dots of paternity success.
