“…In particular, during the driest season, there was a significant correlation between shallower water and the littoral morphotype. These results are a progress on the opinions of Cei and Roig (1968) and Cei (1972), who did not believe that seasonal or cyclical factors were related to the existence of the "forms" of A. patagonicus that they defined.…”

“…At each sampling event, the specimens collected were placed in containers of pond water, counted, length (SVL) and morphotype recorded, and then released at the site they had been captured. For morphotype, the two "forms" by Cei and Roig (1968) were considered. We excluded from the analysis any individuals with other characteristics (presence of integumentary folds and interdigital membranes of medium development, and a uniform, pale yellowish grey ventral colouring), and the newly metamorphosed specimens (≤ 24 mm SVL).…”

“…For Atelognathus patagonicus (Gallardo 1962), an endemic frog restricted to Laguna Blanca National Park and its surroundings, in NW Argentinean Patagonia, two "forms" have been described: "aquatic" and "littoral" (Cei and Roig 1968). The "aquatic form" lives in ponds, associated with underwater rocks, and has well-developed cutaneous folds, extensive interdigital membranes and an orange-yellow ventral surface.…”

“…The morphological differences, co-occurrence and different ecological niches of each "form" led Cei and Roig (1968) to propose that the two "forms" were in fact sympatric species. In two studies no relationship was found between the two "forms" and animal age or season (Cei andRoig 1968, Cei 1972).…”

Relationship between morphotypes of Atelognathus patagonicus (Anura, Neobatrachia) and environmental conditions: evidence and possible explanation. The frog Atelognathus patagonicus (Gallardo, 1962) is endemic to an endorheic pond system in basaltic basins, in Laguna Blanca National Park and its surroundings, in northwest Argentinean Patagonia. The species has two morphotypes, aquatic and littoral, which were studied in Laguna Batea, a semi permanent pond. Aquatic and terrestrial samples were taken over a period of 31 months, including periods of drought and periods of normal precipitation. Evidence was found of the reversible character of the two morphotypes. The changes in the phenotype were consistent with the water level and limnological conditions in the pond. We believe that the change and subsequent reversal of the somatic features in these frogs are an opportunistic alternative showing remarkable plasticity of the species, which can thus inhabit both permanent and temporary ponds. Therefore, the two morphotypes, aquatic and littoral, cannot be considered as "fixed forms" within a given population, as other authors have speculated, and do not correspond to ontogenetic states.

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.
