“…Crossodactylus aeneus occurs in the states of Rio de Janeiro and São Paulo and in southeastern Brazil, from altitudes of 100-1200 m above sea level (asl; Pimenta and Segalla 2010;Siqueira et al 2013;Frost 2014). This species inhabits the margins of rocky streams in the forest (Jordão-Nogueira et al 2006) and belongs to the C. gaudichaudii group, which is presently composed of seven species: C.…”

“…1). Between didactylus and ephippium groups, syntopy has been reported in four localities: between B. didactylus and B. ephippium in the Reserva Ecológica Rio das Pedras, Rio de Janeiro (Carvalho-e- Silva et al 2008;Almeida-Santos et al 2011;; between B. didactylus and B. margaritatus in the Sacra Família do Tinguá, Rio de Janeiro (Izecksohn 1971;Pombal 2001;Ribeiro et al 2005;Alves et al 2006Alves et al , 2009; Silva et al (Siqueira et al 2011(Siqueira et al , 2013; and between B. hermogenesi and B. ephippium in the Reserva Florestal de Morro Grande, São Paulo (Dixo & Verdade 2006;Verdade et al 2008). Sympatry and possibly syntopy also between didactylus and ephippium groups was reported in the state of São Paulo in two localities (Tab.…”

“…The occurrence of B. ephippium in distinct relief units should be the subject of further scrutiny. In particular, populations under that name might indeed represent cryptic species that would have to be split (see also Dixo & Verdade 2006;Silva et al 2007;Clemente-Carvalho et al 2008, 2011bCampos et al 2010;Campos 2011;Siqueira et al 2013;Trevine et al 2014).…”

“…Two of them were here assigned to the ephippium group because they probably represent populations of B. ephippium that could be split into two species, one of which from the state of Rio de Janeiro (Siqueira et al 2013; see also Siqueira et al 2011) and the other from the state of São Paulo (Pie et al 2013). A third undescribed species was assigned to the didactylus group because it represents a population to be split from B. hermogenesi (Pie et al 2013), a representative species from the didactylus group.…”

Peer Review #1 of "Geographical and altitudinal distribution of Brachycephalus (Anura: Brachycephalidae) endemic to the Brazilian Atlantic Rainforest (v0.2)"

2016

Mountains of the Brazilian Atlantic Forest can act as islands of cold and wet climate, leading to the isolation and speciation of species with low dispersal capacity, such as the toadlet species of the genus Brachycephalus. This genus is composed primarily by diurnal species, with miniaturized body sizes (< 2.5 cm), inhabiting microhabitats in the leaf litter of montane forests. Still little is known about the geographical distribution, altitudinal range, and ecological limits of most Brachycephalus species. In this study we review the available data on the geographical and altitudinal distribution of Brachycephalus based on occurrence records compiled from literature and museums, both for the genus as a whole and separately for the three recently proposed groups of species (ephippium, didactylus, and pernix). The final ensemble dataset comprised 333 records, 120 localities, 28 described species, and six undescribed ones. Species were recorded in six relief units, the richest of which being the Serra do Mar, with 30 species. When the Serra do Mar is subdivided into three subunits, Northern, Central and Southern Serra do Mar, the number of species increase from north to the south, with records of six, nine, and 16 species, respectively. We were able to estimate the extent of occurrence of nearly half of the described species, and the resulting estimates indicate that many of them show remarkably small ranges, some of which less than 50 ha. Brachycephalus species are present from sea level to roughly 1,900 m a.s.l., with the highest richness being found between 751 and 1,000 m a.s.l. (21 spp.). The species with the broadest altitudinal range

“…Some of these, and even a few that are classified as DD, have not been recorded for decades and are possibly extinct, as is the case of Aplastodiscus musicus, Holoaden bradei and Thoropa petropolitana. Although conservation strategies tend to prioritize threatened species, IUCN has recommended to give similar attention to the species considered as "data deficient" (DD), though this is still not being properly done (Pimenta et al 2005;Siqueira et al 2013). Species labeled as "DD" currently represent 19% (N = 38) of the amphibian fauna of Rio de Janeiro (Table 1) and, considering that the threat status of several recently described species have not yet been evaluated by the IUCN (2016), this number tends to increase.…”

The amphibians of the state of Rio de Janeiro, Brazil: an updated and commented list

2018

View full text Add to dashboard Cite

The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197 anurans and four caecilians) in Rio de Janeiro, with 54 of them (ca. 27%) considered to be endemic of the state. Our study presents an increase in species richness of 21% since the publication of the previous list, indicating a consistent advance in knowledge of the composition of the amphibian fauna in the state. In spite of its relatively small territorial extension (total area ca. 43,800 km²), the state of Rio de Janeiro contains nearly 20% of the amphibian species known to occur in Brazil and around 40% of those occurring in the Atlantic Forest biome. Thus, that state constitutes an important reservoir of amphibian biodiversity in the Atlantic Forest biome and in Brazil, as a whole.
