Appendix A (Table A1). A table of body proportions of the Bosmina morphs used in the preparation of plastic models.

Body proportions of the seven Bosmina morphs used in the preparation of plastic models. H/L is body height divided by body length, A/L is antennule length divided by body length and TH/L is body thickness divided by body length, measurements according to Hellsten and Stenson (1995). The abbreviations stand for parthenogenetic female (pF), sexual female (sF) and male (m).
