Fig. 3From: Morphology is not a reliable taxonomic tool for the genus Lernaea: molecular data and experimental infection reveal that L. cyprinacea and L. cruciata are conspecificPrincipal components analysis (PCA) ordination showing the difference of morphological features between the two different Lernaea species collected in the wild and from an experimental (laboratory) infection. Abbreviations: Lcy, L. cyprinacea; Lcr, L. cruciate; l, specimens collected from the laboratory infection; w, specimens collected in the wild. Notes: Samples are divided into four groups (1 to 4). For example, 4_Lcr_l indicates group 4, comprising specimens of L. cruciata collected from the laboratory infectionBack to article page
