Figure 10 in Advertisement call, tadpole morphology, and other natural history aspects of the threatened poison frog Andinobates daleswansoni (Dendrobatidae)
Figure 10. Alternative hypothetical reconstruction of characters considering the presence a) and absence b) of the gap in the lower lip in tadpoles of A. dorisswasonae (unknown at present), and considering two alternative phylogenetic placement of A. daleswansoni, as sister to A. dorisswasonae c), and as sister to all species of the A. bombetes species group d). Note that under a, c, and d the presence of the gap would optimise as a synapomorphy for the A. bombetes species group.

Figure 8. Principal component (PC) ordination biplots of habitat preferences of tadpoles of four common Mantidactylus species in the subgenus Chonomantis, sampled during a tadpole community study in Ranomafana National Park and identified by DNA barcoding.

Figure 7 in Morphological and ecological uniformity in the funnel-mouthed tadpoles of Malagasy litter frogs, subgenus Chonomantis
Figure 7. Histogram showing the mean preferences for microhabitat structures by tadpoles of six Mantidactylus species in the subgenus Chonomantis, sampled during a tadpole community study in Ranomafana National Park. Ivlev's electivity index (E, Ivlev, 1961) is plotted for each species and each microhabitat. Positive values indicate that microhabitat was used more often than expected by chance, negative values represent an avoidance of microhabitat structure. Missing bars show that the respective microhabitat was not available to the specific species.
