  1. No inbreeding depression but increased sexual investment in highly inbred ant colonies Volume 21, Issue 22, 5613–5623, Article first published online: 8 October 2012

In Kureck et al. (2012), Figs 2 and 3 have been exchanged and so appear with the wrong legends. The correct figures and captions are presented here (Figs 2 and 3).

Figure 2.

Allometric changes in worker morphology with season. Head width and thorax width are represented by the mean ± SE, as estimated by the linear mixed-effect model, n = 151.

Figure 3.

Relationship between colony-level homozygosity (HL) and the reproductive allocation ratio (relative investment in sexuals vs. workers). Regression lines are derived from the overdispersed logistic regression model presented in Table 2. Character sizes reflect the total sample size (i.e. the weights in the logistic regression): small: <10 individuals, intermediate: 10–40 individuals, large: >40 individuals. Summer: n = 12; fall: n = 31.

Further, there are two incorrect citations in the second paragraph of the Introduction. The sentences with the correct citations should be: ‘In addition, in social insects, inbreeding can compensate for the reduction in relatedness and thereby restore fitness benefits to altruistic workers in colonies with multiple reproductives (Thurin & Aron 2009; Thurin et al. 2011). Indeed, not only a lack of inbreeding avoidance (Keane et al. 1996; Dewsbury 1988; Keller & Fournier 2002) but even preferential inbreeding has been described in social and nonsocial species (Thünken et al. 2007; Thurin & Aron 2009)’.

Hence, the reference ‘Haag-Liautard et al. 2009’ in the original article should in this paragraph be exchanged by the correct reference ‘Thurin & Aron 2009’. Thurin and Aron (2009) found evidence for active inbreeding in the ant Plagiolepis pygmaea. In this species, workers repel unrelated males that try to enter the colony and queens preferentially mate with close relatives. Inbreeding here maintains high levels of relatedness within colonies despite the co-occurrence of multiple queens that mate multiply.
