The correction concerns figure 2, in which the sizing of panels (b) and (d) and the scale bar were not correct. The panels were resized in the revised figure, and the value of the scale bar adjusted to 1 mm instead of 200 µm. Changes to this figure and its caption do not impact any of the analyses, results, interpretations or conclusions.

Figure 2.

Plates from wild-caught individuals of Psolus fabricii of different sizes, with different numbers of growth rings: (a) 4 rings, (b) 10 rings, (c) 12 rings and (d) 28 rings. One pair, consisting of a dark and a light ring, was considered to represent 1 year of growth. Therefore, the innermost rings of individuals shown in (a), (b), (c) and (d) were, respectively, developed in 2013, 2007, 2005 and 1989 and all the outermost rings were developed in 2017. The scale bar at the bottom represents 1 mm. (Online version in colour.)
