Fig. 4 in Variability on microevolutionary and macroevolutionary scales: a review on patterns of morphological variation in Cnidaria Medusozoa
Fig. 4 Schematic summary of levels of morphological variation found in medusozoans, including the absence of variation (cryptic species). Clades indicate different lineages, colors and shades represent the phenotype in current time, and the circles represent individuals. Note that there is individual variation (arrows) and it can parallel intraspecific variation. The same occurs with interspecific variation, which can parallel intraspecific variation in b

Fig. 2 in Molecular and morphological variation among the European species of the genus Aphidius Nees (Hymenoptera: Braconidae: Aphidiinae)
Fig. 2 Maximum parsimony analysis of Aphidius mitochondrial COI haplotypes. The evolutionary history was inferred using the maximum parsimony method. The percentage of replicate trees in which> 90% of the associated taxa clustered together in the bootstrap test (500 replicates) is shown next to the branches. The MP tree was obtained using the close-neighbour-interchange algorithm with search level 1, in which the initial trees were obtained with the random addition of sequences. The tree is drawn to scale, with branch lengths calculated using the average pathway method and expressed in units of the number of changes over the whole sequence. The description of haplotypes is given in Table 1.
