“…nov. (Maya) the call samples come from Mexico (Chiapas), and the H. fleischmanni call samples come from Costa Rica (see Vargas-Masís, 2019;Zamudio-Torres et al, 2020). We used the calls (peak frequency, bandwidth, call duration) to compare populations and species identification since some authors suggest that bioacoustics analyses may be a reliable and effective tool in diagnosing and delimiting species (Köehler et al, 2017;Rodriguez et al, 2017). In addition, recent evidence suggests differences between call traits within genetic groups of H. viridissimum comb.…”

Introduction: Glass frogs occur from Mexico to South America, and, their taxonomy and distribution are currently debated. In El Salvador, the only species is thought to be Hyalinobatrachium fleischmanni, but it may instead be Hyalinobatrachium viridissimum. In any case, the species is scarcely recorded and understudied. Objective: To estimate the species distribution in the Río Lempa basin, and to compare its call with available records. Methods: We used local volunteers to sample 53 sites in Cabañas and Morazán, El Salvador, during the rainy season (September to November); these were visited once in 2019 and once in 2020. Volunteers counted individuals along transects from 6 to 8 pm and recorded some calls with cell phones. Results: We counted 361 individuals, added 53 new localities (mainly deciduous broad-leaved forest and agricultural systems). Abundance was more related with elevation and forest cover, than with river characteristics. Our evaluation of 32 calls found differences in the peak frequency between these glass frog populations and those of H. fleischmanni and H. viridissimum comb. nov. Conclusion: Salvadorian glass frogs are more widespread than previously recorded, their distribution is more related with elevation and forest than with rivers types, and their taxonomic status remains unsolved.

“…nov. Therefore, by analyzing the calls of the glassfrog from El Salvador it is possible to have notions about their taxonomy (Köehler et al, 2017;Rodriguez et al, 2017;Mendoza-Henao et al, 2020), and as well as knowing the characteristics of their calls, aspects that to date have not been studied.…”

“…Cuba is home to 57 currently recognized species of frogs belonging to the genus Eleutherodactylus (Rodríguez et al 2017). Several bioacustic and ethological studies have addressed these frogs Alonso et al 2007;Díaz and Cádiz 2007;Rodríguez et al 2010), but only addressed anuran movement patterns and vocal activity during the nocturnal cycle.…”

In this study, we examined movement patterns, vocal activity, and variation in advertisement calls at individual and populational levels in a population of Western Cuban Grassfrogs (Eleutherodactylus varleyi) at the National Botanical Garden of Cuba in July and September in 2007. Males appear to be very sedentary with peaks of movement early in the night and just before dawn that could be related with the search of calling sites and diurnal retreats, respectively. We detected eight patterns of frequency modulation of advertisement calls for note 1 and six for note 2. Patterns II and VI were the most frequent for note 1 and note 2, respectively. Note duration was the only acoustic parameter that was significantly variable among individuals for note 1, whereas the maximum frequency and rise time were significantly variable within individuals for note 2, suggesting that the latter is more reliable for distinguishing individual calls.

“…For frogs as well as some other vocalizing taxa (e.g., insects, birds), otherwise cryptic species can often be differentiated by their audial signature, and bioacoustic analysis is an important tool for recognizing new or overlooked species [ 9 ]. Investigations have uncovered cryptic species in a variety of settings, including surprising locations and among presumably well-known taxa [ 8 , 10 – 12 ].…”

Follow-up ecological studies for cryptic species discoveries: Decrypting the leopard frogs of the eastern U.S.

Cryptic species are a challenge for systematics, but their elucidation also may leave critical information gaps about the distribution, conservation status, and behavior of affected species. We use the leopard frogs of the eastern U.S. as a case study of this issue. We refined the known range of the recently described Rana kauffeldi, the Atlantic Coast Leopard Frog, relative to the region’s two other leopard frog species, conducted assessments of conservation status, and improved methods for separating the three species using morphological field characters. We conducted over 2,000 call and visual surveys and took photographs of and tissue samples from hundreds of frogs. Genetic analysis supported a three-species taxonomy and provided determinations for 220 individual photographed frogs. Rana kauffeldi was confirmed in eight U.S. states, from North Carolina to southern Connecticut, hewing closely to the Atlantic Coastal Plain. It can be reliably differentiated in life from R. pipiens, and from R. sphenocephala 90% of the time, based on such characters as the femoral reticulum patterning, dorsal spot size and number, and presence of a snout spot. However, the only diagnostic character separating R. kauffeldi from R. sphenocephala remains the breeding call described in 2014. Based on our field study, museum specimens, and prior survey data, we suggest that R. kauffeldi has declined substantially in the northern part of its range, but is more secure in the core of its range. We also report, for the first time, apparent extirpations of R. pipiens from the southeastern portion of its range, previously overlooked because of confusion with R. kauffeldi. We conclude with a generalized ecological research agenda for cryptic species. For R. kauffeldi, needs include descriptions of earlier life stages, studies of niche partitioning with sympatric congeners and the potential for hybridization, and identification of conservation actions to prevent further declines.
