Descripción
Vitreorana uranoscopa inhabits small or medium-sized streams with rocky bottoms of the Interior Atlantic Forest of eastern Brazil, northeastern Argentina, and likely southeastern Paraguay. Most of the available information originates from Brazilian populations. Only a few populations from Argentina have been reported and information about their natural history is almost unknown. This work re-describes the advertisement call of V. uranoscopa from a new population discovered in the province of Misiones, Argentina, and includes further data about its reproduction, population density and habitat conservation status. On the basis of 11 recorded males, two call types were recorded. Results showed that the typical advertisement call is formed by pulsed notes released singly, in groups, or in combinations of both at an average rate of 13.86 notes/min. Notes lasted 0.013-0.085 s and had 1-5 well-defined pulses lasting 0.003-0.015 s; the pulse repetition rate was 90.9-166.66 pulses/s. The peak of dominant frequency was 4,312.5-4,875.0 Hz with a slight, ascending frequency modulation. These data agree with those reported in previous studies, although some differences in the note duration, intercall interval, number of pulses and harmonics were identified. These differences might be due to either the technological limitations at the time of those studies or interpopulation variation. The second call type (reported for the first time in V. uranoscopa) is formed by 1-2 additional pulses at the beginning of some notes and has lower amplitude than typical calls, but the social context of its emission is still unknown. The calling males perched on the leaves of the marginal vegetation, either alone or occasionally in groups of 2-3 individuals, with a average of 5.5 individuals per 100 m transect. Clutches containing up to 36 eggs or embryos were found on the upper surface of fern fronds. In Argentina, V. uranoscopa occurs only in Araucaria forests of the Interior Atlantic Forest. Thus, the protection of streams with abundant marginal vegetation seems to be essential for the conservation of this species.
Vitreorana uranoscopa habita arroyos de tamaño pequeño o moderado con fondos rocosos del Bosque Atlántico Interior del este de Brasil, nordeste de Argentina y probablemente del área adyacente del sudeste de Paraguay. La mayor parte de la información disponible para esta especie corresponde a poblaciones de Brasil. Sólo unas pocas poblaciones de Argentina han sido mencionadas y datos acerca de su historia natural son casi desconocidos. Este trabajo re-describe el canto de anuncio de V. uranoscopa de una nueva población descubierta en la provincia de Misiones, Argentina, e incluye datos adicionales sobre su reproducción, densidad poblacional y estado de conservación de su hábitat. Sobre la base de 11 machos grabados, dos tipos de cantos fueron registrados. Los resultados mostraron que el canto de anuncio típico está formado por notas pulsadas liberadas solas o en grupos o una combinación de ambas a una tasa promedio de 13.86 notas/min. Las notas duran desde 0.013–0.085 s y tienen de 1–5 pulsos bien definidos que duran entre 0.003–0.015 s; la tasa de repetición de pulsos varió entre 90.9–166.66 pulsos/s. El pico de frecuencia dominante varió desde 4,312.5–4,875.0 Hz. Se observó además una ligera modulación de frecuencia dominante desde el comienzo hasta el final de la nota. Estos valores son similares a los citados en descripciones previas, aunque se encontraron algunas diferencias en la duración de la nota, en el intervalo intercanto, y en el número de pulsos y harmónicos. Estas diferencias pueden estar asociadas con limitaciones tecnológicas al momento de aquellos estudios o variaciones inter-poblacionales. El segundo tipo de canto (reportado por primera vez en V. uranoscopa) está formado por uno a dos pulsos adicionales al comienzo de algunas notas, de amplitud más baja que la de los cantos típicos; su contexto social es aún desconocido. Los machos cantaban sobre las hojas de la vegetación marginal, solos u ocasionalmente en grupos de 2–3 individuos, con un promedio de 5.5 individuos por transecta de 100 m. Se encontraron nidos con hasta 36 huevos o embriones sobre la superficie dorsal de frondes de helechos. En Argentina, V. uranoscopa habita solamente selvas de Araucaria del Bosque Atlántico Interior. La protección de arroyos con abundante vegetación marginal parece ser esencial para la conservación de esta especie.
