“…As far as we know, Pristimantis latro sp. n. represents the first species described to the south of the Amazon River in Pará State, where it was erroneously identified as P. fenestratus due to their morphological similarities (Oliveira et al 2013, Vaz-Silva et al 2015). …”

In this study a new species of Pristimantis (Anura: Craugastoridae) of the P. conspicillatus species group is described. Pristimantis latro sp. n. is known only from the municipalities of Altamira, Anapu, Brasil Novo, Medicilândia, Uruará and Aveiro (Flona Tapajós, right bank of Tapajós river), in Pará state, Brazil. Morphologically, the new species distinguishes from known congeners in the group mainly by the presence of dorsal tubercles and absence of discoidal folds, smooth belly skin, as well as the presence of supernumerary tubercles on hands. The call of the new species consists of seven ascending notes, the first of which has a dominant frequency of 2635 Hz and the last 3272 Hz. Molecular analysis of the 16S mtDNA indicates a genetic distance of 8% to P. chiastonotus, its closet relative, and between 9% and 11% to populations of P. fenestratus.

“…The anuran fauna corresponded to 65.7 % of the recorded species for the Tumucumaque Mountains National Park (Lima 2008), 86.9 % of the species found in the River Cajari Extractive Reserve (Queiroz et al 2011), 60.9 % species recorded during the surveys conducted of the Rio Curiaú Environmental Protection Area (Lima et al 2017), and 90.6 % species of anurans recorded in the Amapá National Forest (Bemício and Lima 2017). This high anurans richness for the Amazonian biome is highly underestimated considering taxonomic problems, recent descriptions of species and taxonomic revisions (Peloso et al 2014; Vaz-Silva et al 2015). …”

“…The main hypotheses proposed to explain barrier formation separating populations and causing the differentiation of species in Amazonia during the course of geological history are based on different factors (Haffer 2008). According the river hypothesis, rivers may play a major role in creating and maintaining high levels of spatial separation of populations (Vaz-Silva et al 2015). …”

“…In the Brazilian Amazonia, knowledge has increased in the last ten years based on studies on anurans composition conducted mostly in the state of Amazonas (França and Venâncio 2010, Ilha and Dixo 2010, Pantoja and Fraga 2012, Prudente et al 2013, Waldez et al 2013, Ferrão et al 2016, Ferreira et al 2017), state of Pará (Ávila-Pires et al 2010, Mendes-Pinto and Souza 2011, Bernardo et al 2012, Vaz-Silva et al 2015), state of Rondônia (Ávila-Pires et al 2010, Piatti et al 2012) and state of Acre (Bernarde et al 2011, Bernarde et al 2013, Miranda et al 2015, Venâncio and Souza 2016, França et al 2017). …”

In this study, the first survey of anuran species in the Cancão Municipal Natural Park is presented, a protected area of approximately 370 hectares of Amazonian forest located in the northwest center region of the state of Amapá, Brazil. The work was performed during the dry and rainy season, through active visual and auditory survey, totaling 216 man hours of sampling effort. Forty-nine species of anuran amphibians were recorded in the Cancão Municipal Natural Park, including three new records: Hyalinobatrachium iaspidiense, Pristimantis cf. ockendeni, and Scinax garbei. Three species, Hyalinobatrachium iaspidiense, Ameerega pulchripecta, and Anomaloglossus baeobatrachus, are listed as Data Deficient and one is listed as Vulnerable (Atelopus hoogmoedi) according red lists of IUCN. The rarefaction curve cumulative species did not reach an asymptote, indicating that site has potential for species that have not yet been recorded. Nine species were represented by only one individual and were considered rare in the studied environments, eight species were defined as common, and the 32 remaining species were classified as having intermediary abundance. Our data indicated that Cancão Municipal Natural Park contains a considerable portion of the anurans species richness of Amapá state, turn the area into a place of great importance for the conservation of the anurans of the Eastern Amazon.

“…Although some studies of Amazonian herpetofauna have been conducted in places far from urban centers (e.g. Frota et al 2005, Prudente & Santos-Costa 2005, Bernarde et al 2006, Turci et al 2008, França & Venancio 2010, Ferrão et al 2012, Pantoja & Fraga 2012, Santos-Costa 2015, Vaz-Silva et al 2015, Rodrigues et al 2016, França et al 2017, Fonseca et al 2019, for example there is a sampling bias in favor of densely populated areas as shown for plants (Nelson et al 1990).…”

Species richness and composition of snake assemblages in poorly accessible areas in the Brazilian Amazonia

et al. 2020

Snakes are a diverse group of terrestrial vertebrates of the order Squamata. Despite that, in the Amazonian biome, information about distribution and identification of snakes is limited when compared to other groups. Additionally, in Amazonia there is a sampling bias towards areas geographically close to urban centers and more densely populated areas. This in turn leads to false distribution gaps in poorly accessible areas of Amazonia. In this article we report the composition of snake assemblages in six areas of the Brazilian Amazonia, based on field sampling conducted over four years using standardized methods. We sampled 70 species from eight families: Typhlopidae (n=1), Leptotyphlopidae (n=1), Anillidae (n=1), Boidae (n=5), Colubridae (n=15), Dipsadidae (n=35), Elapidae (n=7), and Viperidae (n=5). The largest number of species was recorded in the Trombetas River area and the lowest in the Jatapu River area. The total beta diversity was 0.40 and the snake assemblages were structured mainly by replacement (72.5%). The time-limited search was the method that recorded the greatest number of individuals in the studied areas (44.1%) and also the greatest number of species (n=40). However, some species were recorded only by other methods such as interception by pitfall traps with directional fences. Despite the large number of species sampled in the study, no particular area comprised more than 40% of species registered in all the areas, indicating that snakes are poorly detected even with large sampling effort across multiple areas of a species distribution.

Apesar de serem um dos grupos mais diversos do mundo, na Amazônia, as informações acerca da taxonomia e distribuição de serpentes são limitadas quando comparadas com as disponíveis para outros grupos de vertebrados. Além disso, na Amazônia existe um viés de amostragem em áreas geograficamente próximas aos centros urbanos e locais densamente povoados. Isso por sua vez leva a falsas diferenças de distribuição em áreas pouco amostradas.
