Evidence for individual vocal recognition in a pair-bonding poison frog, Ranitomeya imitator
<p>Individually distinctive vocalizations are widespread in nature, although the ability of receivers to discriminate these signals has only been explored through limited taxonomic and social lenses. Here, we asked whether anuran advertisement calls, typically studied for their role in territory defense and mate attraction, facilitate recognition and preferential association with partners in a pair-bonding poison frog (<em>Ranitomeya imitator</em>). Combining no- and two-stimulus choice playback experiments, we evaluated behavioral responses of females to male acoustic stimuli. Virgin females oriented to and approached speakers broadcasting male calls independent of caller identity, implying that females are generally attracted to male acoustic stimuli outside the context of a pair bond. When pair-bonded females were presented with calls of a mate and a stranger, they showed significant preference for calls of their mate. Moreover, behavioral responses varied with breeding status: females with eggs were faster to approach stimuli than females that were pair-bonded but did not currently have eggs. Our study suggests a potential role for individual vocal recognition in the formation and maintenance of pair bonds in a poison frog and raises new questions about how acoustic signals are perceived in the context of monogamy and biparental care.</p>

Data from: Mimetic divergence and the speciation continuum in the mimic poison frog Ranitomeya imitator
While divergent ecological adaptation can drive speciation, understanding the factors that facilitate or constrain this process remains a major goal in speciation research. Here, we study two mimetic transition zones in the poison frog Ranitomeya imitator, a species that has undergone a Müllerian mimetic radiation to establish four morphs in Peru. We find that mimetic morphs are strongly phenotypically differentiated, producing geographic clines with varying widths. However, distinct morphs show little neutral genetic divergence, and landscape genetic analyses implicate isolation-by-distance as the primary determinant of among-population genetic differentiation. Mate choice experiments suggest random mating at the transition zones, although certain allopatric populations show a preference for their own morph. We present evidence that this preference may be mediated by color-pattern specifically. These results contrast with an earlier study of a third transition zone, in which a mimetic shift was associated with reproductive isolation. Overall, our results suggest that the three known mimetic transition zones in R. imitator reflect a speciation continuum, which we have characterized at the geographic, phenotypic, behavioral, and genetic level. We discuss possible explanations for variable progress toward speciation, suggesting that multifarious selection on both mimetic color-pattern and body size may be responsible for generating reproductive isolation.
FIG. 3 in Intraspecific Call Variation in the Mimic Poison Frog Ranitomeya imitator
FIG. 3.—Regressions between (a) elevation and average male mass, (b) average male mass and note length residuals, (c) average male mass and pulse rate residuals, and (d) average male mass and dominant frequency residuals of Ranitomeŋa imitator. Individual dots represent population averages.
FIG. 2 in Intraspecific Call Variation in the Mimic Poison Frog Ranitomeya imitator
FIG. 2.—Clines in advertisement call parameters across three mimetic transition zones of Ranitomeŋa imitator. (a) Banded-striped transition zone, (b) spotted-striped transition zone, (c) striped-varadero transition zone. In all panels, call parameter values for individual R. imitator (represented by dots) are plotted along the sampling transect (x-axis). For all panels, the fit line represents the best-supported model according to the AICc (see Table 2).
FIG. 1 in Intraspecific Call Variation in the Mimic Poison Frog Ranitomeya imitator
FIG. 1.—Advertisement calls of Ranitomeŋa imitator, showing waveforms (above) and spectrograms (below). (a) varadero morph, recording locality Varadero Forest 1, recorded at 27°C (note length = 0.983 s, pulse rate = 37.6 pulses/s, dominant frequency = 5059 Hz); (b) striped morph, recording locality Varadero South Bank, recorded at 26°C (note length = 0.692 s, pulse rate = 34.7 pulses/s, dominant frequency = 5668 Hz); (c) banded morph, recording locality Sauce, recorded at 26°C (note length = 1.044 s, pulse rate = 28.7 pulses/s, dominant frequency = 5003 Hz); (d) spotted morph, recording locality San Jose, recorded at 22°C (note length = 0.777 s, pulse rate = 33.5 pulses/s, dominant frequency = 5194 Hz). The nearly ubiquitous noise occurring at 7 kHz in all recordings is background noise caused by calling insects.
