Abstract Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes of Scinax constrictus and Ololygon centralis, native endemic species from the Brazilian Cerrado. Chromosome preparations for both species were stained with Giemsa for morphological analyses and then impregnated by the Ag-NOR method for localization of the nucleolar organizer region (NOR). Both species had 24 chromosomes, as confirmed by meiotic analyses, which showed 12 bivalents. Chromosome morphologies presented the same pattern for Scinax and Ololygon compared to species already...

Habitat use by a tree frog species of Scinax (Amphibia, Hylidae) at an urban forest fragment from south-eastern Brazil
Provedor de dados: Iheringia Série Zoologia
Autores: Galdino,Conrado A. B.; Carvalho Jr.,Ronald R.; Menezes,Mauren A. V. Noronha e; Nascimento,Luciana B.
We studied the pattern of habitat use by the tree frog Scinax aff. perereca. Fieldworks were performed from August 1996 to August 1997 at Parque das Mangabeiras, Belo Horizonte, State of Minas Gerais, southeastern Brazil. Calling males were observed in September, October and December 1996, February to April and June 1997. Females were found only in October 1996. Specimens were found perched on vegetation, on the ground or on stones near waterfall. At Parque das Mangabeiras, S. aff. perereca occupied nine types of substrata. The most frequently used substrata were shrubs, stones at the stream edges, and fallen trunks. The pattern of spatial occupation varied among months. Males were found calling in aggregations on the vegetation and spatial niche breadth...

Advertisement calls of Bolivian species of Scinax (Amphibia, Anura, Hylidae)
Provedor de dados: Naturalis Digital Academic Repository
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.

Description of the tadpole of Scinax auratus (Wied-Neuwied) (Anura, Hylidae)
Provedor de dados: Zoologia
Autores: Alves,Ana C. R.; Gomes,Márcia dos Reis; Silva,Sergio P. de Carvalho e.
Scinax auratus occurs in the Atlantic Rain Forest of northeastern Brazil. It is found inside the forest on outcrop rocks and in open areas along the forest border. The tadpoles are found in temporary ponds. Herein we describe the tadpole of S. auratus and compare it with those of other related species of the genus Scinax. The diagnostic characteristics of the tadpole of S. auratus include aspects of the general colour and forms of the body, tail, third posterior tooth row, and jaw sheaths.

Organização celular dos testículos em Hylidae e Leptodactylidae, no Pantanal (Estado do Mato Grosso do Sul, Brasil) - DOI: 10.4025/actascibiolsci.v31i4.3332

Autores: Ferreira, Adelina; UFMT; Rosa, Ana Barbara dos Santos; UFMT; Mehanna, Mahmoud; UNESP - campus Botucatu.
O objetivo deste trabalho foi analisar e comparar a organização das células germinativas em diferentes estádios de diferenciação celular nos machos adultos de Dendropsophus nanus (Boulenger, 1889), Pseudis limellum (Cope, 1862), Pseudis paradoxa (Linnaeus, 1758) e Scinax acuminatus (Cope, 1862), pertencentes à família Hylidae, e de Leptodactylus chaquensis (Cei, 1950) e L. podicipinus (Cope, 1862), pertencentes à família Leptodactylidae, coletados no Pantanal e na serra da Bodoquena, no Estado do Mato Grosso do Sul, Brasil. Os testículos foram retirados, fixados, desidratados em uma série alcoólica e incluídos em resina plástica do tipo methacrilato glicol (Historesin Leica®); cortados a 3 &amp;micro;m, corados com azul de toluidina 1% e observados no...
