“…Regarding the distributional patterns of species, we found 10 species endemic to the Cerrado biome (Rhinella veredas , R. cerradensis Maciel, Brandão, Campos & Sebben, 2007, Rhinella mirandaribeiroi (Gallardo, 1965, R. rubescens (A. Lutz, 1925) Miranda-Ribeiro, 1937; (fifteen species with widespread distribution; two endemic to the Caatinga biome, Rhinella jimi (Stevaux, 2002) and Ceratophrys joazeirensis Mercadal de Barrio, 1986); ten species occurring both in the Caatinga and the Cerrado biomes; four occuring in open domains (Caatinga, Cerrado, Pantanal) and six species occurring in the Cerrado and the Amazon Rainforest (Table 1; Figure 3).…”

Abstract:The state of Piauí is located between the Caatinga and Cerrado biomes in Northeastern Brazil, having a rich heterogeneity of habitats. However, publications regarding the amphibians of this state are scarce. We compiled literature data and complemented it with amphibian inventories in some municipalities of Piauí and present a list of 55 species (54 anurans and one caecilian). Ten of them are endemic to the Cerrado biome (Rhinella veredas, R. cerradensis, R. mirandaribeiroi, R. rubescens, Dendropsophus rubicundulus, Phyllomeduza azurea, Leptodactylus pustulatus, Eupemphix nattereri, Physalaemus centralis, and Proceratophrys goyana) and two endemic to the Caatinga (Rhinella jimi and Ceratophrys joazeirensis). We also present data about species richness of 18 sampled municipalities, species distribution patterns, and conservation status.

“…The genus Rhinella (previously classified as Bufo) contains more than 250 species present in the majority of the continents (Frost, 2004;Pramuk, 2006). In Brazil, R. jimi is widely distributed, where it is very common throughout the Northeast region (Stevaux, 2002). Despite their geographic distribution, this species has been studied little, where there are some preliminary data about endoparasitism (Anjos et al, 2009), about antileishmania and antitrypanosome activity of steroids extracted from their skin (Tempone et al, 2008) and antifungic activity .…”

Abstract:The skin of amphibians possesses a large diversity of biologically active compounds that are associated with the natural defenses of these animals against pathogens. Five different extracts and fractions were obtained from the skin of Rhinella jimi: methanol extract (ME), methanol fractions (MF), chloroform extract of methanol extract (CF), aqueous alkaloid fraction (AAF) and aqueous non-alkaloid fraction (ANAF). All fractions were evaluated with respect to their antibiotic modifying activity in standard bacterial strains and multiresistant clinical isolates. Antagonism was detected with kanamycin and gentamicin when combined with substances obtained from the skin of R. jimi. Phototoxic activity was observed in the methanol and chlorophorm fractions, as well as the aqueous non-alkaloid fraction. The antagonistic action was apparently associated with the protection afforded by the bacterial populations that inhabit the skin of this amphibian, preventing colonization by pathogenic fungi. The phototoxic activity demonstrated by natural products from the skin of R. jimi showed an interruption of the bacterial growth after UV exposure. This could indicate an antibacterial effect activated by the UV light, opening a path for carrying the attack by pathogenic fungi, causing the disease related with the amphibian decline.

“…The anurans were Rhinella jimi (Stevaux, 2002), Corythomantis greeningi Boulenger, 1896, andPhysalaemus cicada Bokermann, 1966. The Squamata, consisted of 68 lizards in 10 species from 8 families and 17 snakes in 8 species from 4 families.…”

We present an annotated list of herpetofauna for the municipality of João Câmara, Rio Grande do Norte State (RN), Brazil, in Caatinga domain. The data were obtained through fauna rescue program activities performed during the installation of two wind energy parks. We recorded 10 species of lizards, eight snakes, four amphisbaenids and three anurans. The results obtained present extensions to known geographic distribution for four species (Amphisbaena littoralis, Enyalius bibronii, Epictia borapeliotes and Corythomantis greeningi) and add information to the natural history of the first two species. This constitutes the second list of herpetofauna for RN. Our results show that such studies may contribute useful data on herpetofauna, especially in poorly studied areas.
