FIG. 8 in Hidden Diversity in the Mountain Chorus Frog (Pseudacris brachyphona) and the Diagnosis of a New Species of Chorus Frog in the Southeastern United States
FIG. 8. The distribution (solid gray line) and mean (gray dashed line) of D and I (A, B) niche overlap estimates obtained from MaxEnt models, originating from randomly selecting occurrences (and associated environmental values) in the Southern population. Asymmetric background tests were used to compare these distributions with the empirical estimate from the Northern population (black dashed line). The same procedure was carried out for the reciprocal comparison, Southern vs. Northern (C, D). In both cases, the empirical estimates significantly differed from the randomized distributions, suggesting the absence of niche overlap.
FIG. 6 in Hidden Diversity in the Mountain Chorus Frog (Pseudacris brachyphona) and the Diagnosis of a New Species of Chorus Frog in the Southeastern United States
FIG. 6. Maximum entropy species distribution models (SDMs) for all P. brachyphona (A), Northern (B), and Southern clades (C). Models represent average probability of occurrence based on ten replicates. We applied a 10th percentile threshold rule to the predicted suitability, thus gray pixels in these maps represent suitable habitat. Hollow circles show the location of occurrence records used in the models, and the dashed line indicates the position of the Tennessee River.
Female preferences for more elaborate signals are an emergent outcome of male chorusing interactions in túngara frogs
<p><span>In chorusing species, conspecific acoustic interference exerts strong selection on signal form and timing to maximize conspicuousness and attractiveness within the signaling milieu. We investigated how túngara frog calling strategies were influenced by varied social environments and male phenotypes, and how calling interactions influenced female preferences. When chorusing, túngara frog calls consist of a whine typically followed by 1–3 chucks. In experimental choruses we saw that, as chorus-size increased, calls increasingly had their chucks overlapped by the high-amplitude beginning part of other callers' whines. Playback experiments revealed such overlap reduced the attractiveness of calls to females, but that appending additional chucks mitigated this effect. Thus, more elaborate calls were preferred when calls suffered overlap, though they were not preferred when overlap was absent. In response to increasing overlap risk in larger choruses, males increased call </span><span>elaboration. However, males overwhelmingly produced 2-chuck calls in even the largest choruses, despite our results suggesting additional chucks would more effectively safeguard calls. Furthermore, aspects of male phenotypes predicted to limit call elaboration had negligible or uncertain effects, suggesting other constraints are operating. These results highlight how complex interrelations among signal form, signaling interactions, and the social environment shape the evolution of communication within choruses.</span></p>
