FIGURE 1 in Development of sexual characters in the cave shrimp genus Troglocaris (Crustacea: Decapoda: Atyidae) and their applicability in taxonomy

FIGURE 1. Two-dimensional plot generated from Principal Component Analysis (PCA) run on 49 specimens of Troglocaris s. str. from W-SloKaċna sample. In 43 males of different size (age) and 6 specimens of uncertain sex, 13 ratios are considered. Explanation of group abbreviations: U – juveniles of uncertain sex (i.e. without appendix masculina, sex is not identifiable); A – juvenile males with weakly developed appendix masculina; B – adult males (appendix masculina well developed, see also Figure 4). List of ratios is in Appendix C (under P).
