Dissemination

This endemic species of Brazil comes in the coastal regions of eastern and southern Brazil, from the states of Bahia to Santa Catarina to 1000 m above sea level. MSL.

Description

This kink toes tree frog is very small in comparison to other members of the genus. Teixeira & Vrcibradic ( 2004) studied 110 individuals, of which the males have a head -body length of 14.4 to 20.8 mm ( average 16.2 ± 1.0 mm) and a weight of 0.4-1, 0 g ( average 0.5 ± 0.1 g) had, while the females have a SVL of 18.1 to 23 mm (mean 20.7 ± 1 mm) and a weight of 0.5-12, g ( average 1, 0 ± 0.2 g) showed. The females were significantly larger than the males.

Habitat and Ecology

Scinax argyreornatus comes in both forests and open areas, such as the Restinga bushland, but not in agricultural land before. The species is often found in bromeliads or other forest vegetation near his temporary or permanent reproduction waters. Had the Teixeira & Vrcibradic ( 2004) studied adult females 94-197 (mean 130.1 ± 30.1 ) mature oocytes in their ovaries. It follows that the clutch size of this kind, compared to tree frogs with similar body size is the same size or smaller. In the stomach contents of Teixeira & Vrcibradic (2004) examined animals were found mainly terrestrial isopods and beetle larvae.

Endangering

The IUCN lists Scinax argyreornatus as " not at risk " ( "Least Concern" ). Widespread diffusion and the facts that the species takes a wide range of habitats, the total population shows a stable trend and is sufficiently large estimated reasons for them. The editors see it as unlikely that the populations of the species may decrease fast enough to justify a higher level of danger. Moreover Scinax argyreornatus occurs in several protected areas. agriculture, deforestation and expanding human settlements pose next to the collection of bromeliads, the main hazard reasons the type dar.
