From: Queen pheromones in Temnothorax ants: control or honest signal?
PCO ordination based on the cuticular hydrocarbons profiles from four Temnothorax species. Bidimensional PCO ordination based on the cuticular hydrocarbons profiles of queens (Q) and workers (W) from four different species of Temnothorax ants involved in the mixed-species experiment: T. unifasciatus (Tu Q, n = 5; Tu W, n = 12), T. nylanderi (Tn Q, n = 6; Tn W; n = 9), T. crassispinus (Tc Q, n = 6; Tc W, n = 9), T. recedens (Tr Q, n = 10; Tr W; n = 34). The percentages of variance explained by the two main principal coordinates are given in parentheses.
