“…Santos et al (2014) registered 40 species of amphibians in 17 municipalities of the Piracanjuba and Peixe rivers basins in the southeast of Goiás. In the same way, long-term studies conducted to detect small spatio-temporal variations in the species composition between environments of a same region enable the registration of a greater species number and allows determining the actual species richness in the sampled environments , Gambale et al 2014.…”

The Cerrado is one of the most threatened biomes in Brazil. It is estimated that much of its original vegetation has been replaced by some type of human use. This is quite worrying, mainly in the northern part where the number of wildlife inventories is insufficient and creates the false impression of low diversity in the region. The Parque Estadual do Mirador-PEM, located in the south-central region of the state of Maranhão, presents vegetation typical of the Cerrado biome and corresponds to one of 46 priority areas for conservation in the state. Herein, we describe the species richness and composition of the anurofauna from the PEM and analyze the influence of different types of vegetation in its formation. Our inventory was conducted from December 2013 to February 2015, using the active search and auditory census methods on breeding sites in different water bodies of the park. We recorded 31 anuran species belonging to five families (species number in parentheses): Leptodactylidae (14), Hylidae (12), Bufonidae (3), Microhylidae (1) and Phyllomedusidae (1). The rarefaction curve and species richness estimators indicated that the sampling effort was enough to record most of the species in the region. The richness of anurans in the PEM was higher than reported by other authors for several areas of Cerrado. Most species have a wide distribution in Brazil or are strongly associated with the Caatinga or Amazon biomes. Only about 19% are endemic to the Cerrado biome. This study is the first to inventory the anurans species of the south-central region of state of Maranhão and provides important data on amphibian communities from the northern part of the Brazilian Cerrado.Keywords: inventory, Amphibia, Anura, conservation unit, species richness.

Estima-se que grande parte da cobertura vegetal original deste bioma tenha sido substituída por alguma forma de utilização humana.

“…Considering that the size of the surveyed areas or the sampling effort may influence the amount of species surveyed, our records on species richness are similar to those from termite mounds in contiguous reservoir areas of the Serra da Mesa and Cana Brava hydroelectric power plant (47 species; Moreira et al 2009) as well as other areas in the Cerrado (Recoder et al 2011). Some of the surveyed sites in Cerrado have been reported to show lower reptile richness than recovering Brought to you by | University of Gothenburg Authenticated Download Date | 11/23/17 1:11 PM areas in Niquelândia (Uetanabaro et al 2007;Morais et al 2012;Ramalho et al 2014;Santos et al 2014;Silva et al 2015), while other studies have reported higher richness against our results (Silva Jr. et al 2005Valdujo et al 2009;Araujo & Almeida-Santos 2011). Nevertheless, as most species of reptiles, particularly snakes, tend to have low population densities and/or secretive habitats, the complete inventory of a given place demands a great amount of time and collection effort; consequently, it is highly possible that all above mentioned studies collected only a fraction of the total reptile richness of their study areas.…”

Erratum to: Reptile surveys reveal high species richness in areas recovering from mining activity in the Brazilian Cerrado

Our study determines the reptile species richness, composition, and habitat use in three areas recovering from mining activity in addition to the adjacent pristine and anthropized areas of a priority region for biodiversity conservation of the Brazilian Cerrado. We also compared our data with published surveys on the Cerrado domain in order to identify areas with unique species composition and/or areas where the reptile composition is more homogeneous. The survey was conducted in the municipality of Niquelândia, northern Goiás state, central Brazil, and involved reptile samplings from different physiognomies and water bodies. We found 47 species, including one crocodilian, one chelonian, two amphisbaenians, 17 lizards, and 26 snakes. The list includes 37 species with large geographic distribution, occurring in other morphoclimatic domains, as well as 10 species which are endemic to the Cerrado. Some species recorded for the region are listed in the Appendices I and II of the CITES. Many reptile species were frequently associated with anthropogenic habitats, while others seem to depend on remnants of pristine habitats. Low similarity was found among the 32 sites considered across the Cerrado domain. Ten sites located in Cerrado regions in contact with the adjacent domains have unique reptile composition, whereas most sites largely located in the central area of the domain have reptile communities which are more homogeneous among them. It is important to conduct long-term studies to have patterns of reptile species composition recognized as well as population decline and/or local extinctions and effective reptile conservation actions, with focus on these sites considering their unique species.

“…Although we might conclude that these areas represent distribution gaps, the compilation of point records of Valdujo et al (2012) suggests that GIBF and SpeciesLink are incomplete. For example, in the case of some well-surveyed CER localities, the voucher specimens were deposited in collections not hosted by GIBF and SpeciesLink (e.g., Valdujo et al 2009, Santos et al 2014. Consequently, these localities seem to be under-represented by our density analysis; examples include the Estação Ecológica Serra Geral do Tocantins (states of Tocantins and Bahia, Brazil: Valdujo et al 2011) and southeastern Goiás State (central Brazil: Santos et al 2014).…”

The utility of open-access biodiversity information in representing anurans in the Brazilian Atlantic Forest and Cerrado. Many geographic coordinates of species are only available in biological collections, and sometimes it is difficult to access these data. However, recent initiatives promise to compile and organize such biodiversity data at a global scale. We evaluated the effectiveness of open-access biodiversity information for forecasting the occurrence of anurans in two Brazilian hotspots -the Atlantic Forest (AF) and the Cerrado (CER). We compiled all available point-occurrence records for anuran species in both hotspots and identified the regions in each of the two hotspots having the highest and lowest number of anuran occurrences based on information from the Global Biodiversity Information Facility (GBIF) and the SpeciesLink project. A total of 13,130 point-occurrence records were recovered for 409 anurans from the AF (~77% of the known species) and 12,729 records for 176 species (~85% of the known species) from the CER. Density of point occurrence data is not randomly distributed within the hotspots. The greatest density of Atlantic Forest records is in southeastern Brazil, and the densest areas in Cerrado occur in the transitional zones to the Atlantic Forest. Comparison of these results with previous studies based on traditional museum information revealed that many important collections of anurans from these hotspots are not included in GBIF and SpeciesLink.
