Figure 9 from: Kavanaugh D, Archambeault S, Roopnarine P, Ledford J (2011) A re-consideration of the taxonomic status of Nebria lacustris Casey (Coleoptera, Carabidae, Nebriini) based on multiple datasets – a single species or a species complex?

Figure 9 - Box plots of body size (measured as the first principal component, PC I) segregated by species and gender. 1 = Nebria lacustris, 2 = Nebria bellorum. Mid-lines in boxes represent sub-sample distribution median PC I scores (median body size), lower and upper limits of boxes represent 25% and 75% limits of distributions respectively, and upper and lower whiskers represent 5% and 95% limits respectively. Nebria lacustris adults are significantly larger than those of Nebria bellorum, and females of both species are significantly larger than males.
