On the distinctive call of a threatened phenotype of Allobates femoralis (Anura: Aromobatidae) and its recognition by allopatric conspecific males
Provedor de dados: 76
Autores: Pontes-da-Silva,Emerson; Lima,Albertina P.; Simões,Pedro I.
ABSTRACT The brilliant-thighed frog [Allobates femoralis (Boulenger, 1884)]; is distributed across the Amazon basin and aggregates several allopatric evolutionary lineages, some of which present variation in their advertisement calls. In 2009, an unregistered call phenotype was discovered in the region of Altamira and Vitória do Xingu, State of Pará, Brazil, where males emit advertisement calls formed by six notes, differing from the typical four-note calls described for other A. femoralis populations. In this study, we describe in detail these untypical calls. Additionally, we test whether the aggressive responses of males of a 4-note reference population (Reserva Ducke - RFAD, in Manaus, State of Amazonas) is differential towards the 6-note calls of...

Advertisement calls of Bolivian species of Scinax (Amphibia, Anura, Hylidae)
Provedor de dados: 16
Autores: Riva, Ignacio de la; Márquez, Rafael; Bosch, Jaime.
The advertisement calls of eight Bolivian species of Scinax are described including information on the calling behaviour of each species. A characteristic audiospectrogram and oscillogram are presented for each species, as well as numerical information about the spectral and temporal features of the calls. Two phenograms based on the characteristics of the mating calls are constructed, the first one using a traditional multivariate technique (UPGMA) and the second one using audiospectrogram correlation, a new technique that allows holistic comparisons of single vocalizations.

Does advertisement call variation coincide with genetic variation in the genetically diverse frog taxon currently known as Leptodactylus fuscus (Amphibia: Leptodactylidae)?
Provedor de dados: 42
Autores: HEYER,W. RONALD; REID,YANA R.
The frog Leptodactylus fuscus is found throughout much of South America in open and disturbed habitats. Previous study of genetic differentiation in L. fuscus demonstrated that there was lack of genetic exchange among population units consistent with multiple species, rather than a single species. We examine advertisement vocalizations of L. fuscus to determine whether call variation coincides with genetic differentiation. Calls were analyzed for 32 individual frogs from 25 localities throughout the distributional range of L. fuscus. Although there is variation in calls among geographic samples, call variation is not concordant with genetic variation or geographic distance and the call variation observed is less than that typically found among other...
