Figure 2.
The negative correlation between M. arenarius colony genetic relatedness and (A) foraging performance (average of seed collection), and (B) nest maintenance (proportion of obstacle removal), in bright gray dots. (C) The negative correlation between M. sp. colony genetic relatedness and colony overall aggression (the sum of the aggression indices for the three encounter types), in dark gray dots. Note that the Y axis scale differs from the scale in Fig. 3A, because here we present the sum of aggression levels during the different encounter types.
