“…Hyla andersonii is considered a habitat specialist on seepage bogs for breeding (Means & Longden ; Cely & Sorrow ; Zampella & Bunnell ; Means ), although habitat characterization has not been adequately studied. As a result, male frogs may be calling in environments with different sound attenuation properties (Röhr & Juncá ) or they may adjust their calls given their environment (Lardner & bin Lakim ).…”

Geographic variation in the Pine Barrens Treefrog (Hyla andersonii): concordance of genetic, morphometric and acoustic signal data

Delimiting species is important to every subfield in biology. Templeton's cohesion species concept uses genetic and ecological exchangeability to identify sets of populations that ought to be considered as the same species, and the lack of exchangeability helps determine which populations can be grouped as evolutionarily significant units (ESU) in conservation science. However, previous work assessing genetic and ecological interchangeability among populations has been limited in scope. Here, we provide a method for assessing exchangeability that incorporates multiple, independent lines of multivariate evidence in genetic, behavioural and morphological data. We use this approach to assess exchangeability across three disjunct groups of populations of the Pine Barrens Treefrog (Hyla andersonii) from the eastern United States. This species is considered threatened by each state in which it occurs and conservation management of this taxon requires a clearer understanding of how populations in these three regions may differ from one another. We find a strikingly concordant pattern in which the first axis of variation for each of the three types of data distinguishes populations along a latitudinal gradient and the second axis distinguishes the set of populations occurring in the Carolinas from those occurring in the New Jersey and Florida/Alabama regions. We know of no comparable data set that displays such concordance among different types of data across so large a geographic range. The overlap in trait values (i.e. exchangeability) between neighbouring regions, however, is substantial in all three types of data, which supports continued consideration of this taxon as a single species.

“…Although many aspects of anuran communication have been studied intensively, the adaptation of signaling behavior in different environments ('acoustic adaptation hypothesis') has only rarely been examined-especially at the intraspecific level-and the existing studies had ambiguous outcomes (Wells & Schwartz 1982;Zimmermann 1983;Penna & Solis 1998;Kime et al 2000;Bosch & De la Riva 2004;Boeckle et al 2009;Ziegler et al 2011;Penna et al 2013;Röhr & Juncá 2013;Vargas-Salinas & Amézquita 2014; for reviews see Ey & Fischer 2009;Erdtmann & Lima 2013;Villanueva-Rivera 2014), and there is little evidence for different environments influencing signal structure in frogs. One example at the inter-specific level comes from the North American cricket frog (Acris crepitans complex).…”

Vocalizations of anuran amphibians have received much attention in studies of behavioral ecology and physiology, but also provide informative characters for identifying and delimiting species. We here review the terminology and variation of frog calls from a perspective of integrative taxonomy, and provide hands-on protocols for recording, analyzing, comparing, interpreting and describing these sounds. Our focus is on advertisement calls, which serve as premating isolation mechanisms and, therefore, convey important taxonomic information. We provide recommendations for terminology of frog vocalizations, with call, note and pulse being the fundamental subunits to be used in descriptions and comparisons. However, due to the complexity and diversity of these signals, an unequivocal application of the terms call and note can be challenging. We therefore provide two coherent concepts that either follow a note-centered approach (defining uninterrupted units of sound as notes, and their entirety as call) or a call-centered approach (defining uninterrupted units as call whenever they are separated by long silent intervals) in terminology. Based on surveys of literature, we show that numerous call traits can be highly variable within and between individuals of one species. Despite idiosyncrasies of species and higher taxa, the duration of calls or notes, pulse rate within notes, and number of pulses per note appear to be more static within individuals and somewhat less affected by temperature. Therefore, these variables might often be preferable as taxonomic characters over call rate or note rate, which are heavily influenced by various factors. Dominant frequency is also comparatively static and only weakly affected by temperature, but depends strongly on body size. As with other taxonomic characters, strong call divergence is typically indicative of species-level differences, whereas call similarities of two populations are no evidence for them being conspecific. Taxonomic conclusions can especially be drawn when the general advertisement call structure of two candidate species is radically different and qualitative call differences are thus observed. On the other hand, quantitative differences in call traits might substantially vary within and among conspecific populations, and require careful evaluation and analysis. We provide guidelines for the taxonomic interpretation of advertisement call differences in sympatric and allopatric situations, and emphasize the need for an integrative use of multiple datasets (bio-acoustics, morphology, genetics), particularly for allopatric scenarios. We show that small-sized frogs often emit calls with frequency components in the ultrasound spectrum, although it is unlikely that these high frequencies are of biological relevance for the majority of them, and we illustrate that detection of upper harmonics depends also on recording distance because higher frequencies are attenuated more strongly. Bioacoustics remains a prime approach in integrative taxonomy of anurans if uncertainty due to possible intraspecific variation and technical artifacts is adequately considered and acknowledged.

“…For example, a frog that moves from an aquatic to a nonaquatic calling site will likely experience stronger constraints on the inflation of the lungs and vocal sac. This will result in an immediate impact on call frequency, as suggested by experiments on túngara frogs (Goutte et al, 2020) and acoustic measurements of calling male hylids (Camurugi et al, 2015;Röhr & Juncá, 2013). Therefore, the impact of the environment, and in particular of display sites, on vocal production mechanisms has the potential to cause fast signal divergence, and in some cases promote speciation.…”

Animals communicate with an extraordinary variety of display behaviours that span most sensory modalities (Bradbury & Vehrencamp, 2011; Stevens, 2013). These chemical, visual or acoustic signals are known to experience strong selection pressures imposed by intended and unintended receivers, in particular in the context of sexual communication. The balance between sexual (e.g. mates) and natural selection pressures (e.g. eavesdropping predators) is, however, not independent from the environment. By
