Figure 7 in Food storage and morphological divergence between worker and soldier castes in a subterranean myrmicine ant, Carebara perpusilla

Figure 7. Micro-CT comparison of replete worker and soldier (scaled) showing how the crop (blue asterisk) occupies most of the abdomen: 60% in workers, 92% in soldiers (calculated from three perpendicular axes). The crop of the soldier (0.306 mm3) is 25 times larger than the crop of the worker (0.012 mm3). Notice how the midgut is squeezed against the exoskeleton by the crop. See figure 8A for a non-replete soldier crop. Pictures were obtained with Drishti and show a superposition of 20 slices.

Figure 5 in Morphological trends and genetic divergence in anacondas, genus Eunectes Wagler, 1830 (Serpentes: Boidae)

Figure 5. Phylogenetic tree (left) and haplotype network (right) based on the analysis of mitochondrial Cytochrome b sequences. Bayesian inference tree is shown; the nodes with the posterior probability support below 0.5 are shown as unresolved. Above the nodes, posterior probabilities are shown, and bootstrap values inferred from ML analysis with RaxML if exceeding 50. The boxes indicate 95% HPD intervals for the estimated split times. Haplotype/ allele networks: size of the pies are proportional to the number of individuals/ alleles.

Figure 4. Assignment of the 20 individuals in the RAPD dataset to genetic groups using STRUCTURE analyses for K = 3 optimal number of clusters (L(K) = -914.64). Each individual is represented by a column, which is partitioned in K coloured segments that represent the genetically based membership to each species cluster. The labels below indicate the species and specimens labels used in the RAPD (and partly sequencing) analysis.
