“…Here, we see similar tradeoffs in acoustic signals, but over 24 hour timescales and across a subfamily rather than within a genus. Interestingly, closely related Phaneropterinae that occupy other habitats produce substantially more sound (Heller and von Helversen 1993;Zhantiev and Korsunovskaya 2005), indicating that the tradeoffs seen in this study are likely a property of the habitat, not the entire taxonomic group, and that species have conformed to this relationship through multiple instances of colonization and evolution. The pervasiveness of tradeoff relationships across species highlights the potential existence of broad structuring principles that shape the spatial and temporal dynamics of communication across taxa.…”

Researchers have long examined the structure of animal advertisement signals, but comparatively little is known about how often these signals are repeated and what factors predict variation in signaling rate across species. Here, we focus on acoustic advertisement signals to test the hypothesis that calling males experience a tradeoff between investment in the duration or complexity of individual calls and investment in signaling over long time periods. This hypothesis predicts that the number of signals that a male produces per 24 hours will negatively correlate with 1) the duration of sound that is produced in each call (the sum of all pulses) and 2) the number of sound pulses per call. To test this hypothesis, we measured call parameters and the number of calls produced per 24 hours in 16 species of sympatric phaneropterine katydids from the Panamanian rainforest. This assemblage also provided us with the opportunity to test a second taxonomically-specific hypothesis about signaling rates in taxa such as phaneropterine katydids that transition from advertisement calls to mating duets to facilitate mate localization. To establish duets, male phaneropterine katydids call and females produce a short acoustic reply. These duets facilitate searching by males, females, or both sexes, depending on the species. We test the hypothesis that males invest either in calling or in searching for females. This hypothesis predicts a negative relationship between how often males signal over 24 hours and how much males move across the landscape relative to females. For the first hypothesis, there was a strong negative relationship between the number of signals and the duration of sound that is produced in each signal, but we find no relationship between the number of signals produced per 24 hours and the number of pulses per signal. This result suggests the presence of cross-taxa tradeoffs that limit signal production and duration, but not the structure of individual signals. These tradeoffs could be driven by energetic limitations, predation pressure, signal efficacy, or other signaling costs. For the second hypothesis, we find a negative relationship between the number of signals produced per day and proportion of the light trap catch that is male, likely reflecting males investing either in calling or in searching. These cross-taxa relationships point to the presence of pervasive trade-offs that fundamentally shape the spatial and temporal dynamics of communication.

To find a mate, male and female bush-crickets of the family Phaneropteridae typically engage in duets. The male sings and the female responds. For mutual recognition, the amplitude pattern of the male song and the species-specific timing of the female response have been shown to be very important. In the seven studied species, belonging to the genera Leptophyes and Andreiniimon, these duets are extremely fast and nearly completely in the ultrasonic range. The females produce very short sounds by fast closing movements of the tegmina. They respond with species-specific delays of 20 to 150 ms after the beginning of the male song. The different latency times are probably not important for species recognition, since in sympatric species they are quite similar.

“…Such character‐based species definitions imply a direct link to a mechanism of reproductive isolation, and such characters are, therefore, a prime candidate for understanding the bush cricket's diversification (Heller et al, 2015; Heller & Hemp, 2020). However, sometimes there are individuals of intermediate morphologies between species, which has fuelled taxonomic discrepancies (Borissov et al, 2023; Chobanov et al, 2015; Kaya et al, 2012; Ramme, 1933; Tarbinsky, 1932; Ünal, 2012; Zhantiev & Korsunovskaya, 2015). Moreover, variation in the cerci (namely, in length, curvature, thickness, apical structure and the number/orientation of distal teeth) and variation in temporal parameters of the three types of male calling song (see Chobanov et al, 2015; Kaya et al, 2012) may represent a breakdown of reproductive barriers, or the ephemerality of incipient species divergences (Rosenblum et al, 2012).…”

The complex and dynamic history of the Anatolian Peninsula during the Pleistocene set the stage for species diversification. However, the evolutionary history of biodiversity in the region is shrouded by the challenges of studying species divergence in the recent, dynamic past. Here, we study the Poecilimon bosphoricus (PB) species group to understand how the bush crickets' diversification and the regions' complex history are coupled. Specifically, using sequences of two mitochondrial and two nuclear gene segments from over 500 individuals for a comprehensive set of taxa with extensive geographic sampling, we infer the phylogenetic and geographic setting of species divergence. In addition, we use the molecular data to examine hypothesized species boundaries that were defined morphologically. Our analyses of the timing of divergence confirm the recent origin of the PB complex, indicating its diversification coincided with the dynamic geology and climate of the Pleistocene. Moreover, the geography of divergence suggests a history of fragmentation followed by admixture of populations, suggestive of a ring species. However, the evolutionary history based on genetic divergence conflicts with morphologically defined species boundaries raising the prospects that incipient species divergences may be relatively ephemeral. As such, the morphological differences observed in the PB complex may not to be sufficient to have prevented homogenizing gene flow in the past. Alternatively, with the recent origin of the complex, the lack of time for lineage sorting may underlie the discord between morphological species boundaries and genetic differentiation. Under either hypothesis, geography—not taxonomy—is the best predictor of genetic divergence.
