“…The relationship between humidity and the increased risk of snakebites is owing to the fact that in humid seasons, the species that snakes feed on (such as anurans, lizards, and small mammals) are more active; further, their young are born at this time 26,27,28 . At the same time, Bothrops are also more active, and their pups are born 29,30,31,32,33,34,35 . Coincidentally, there is an intensification of human activities in rural areas, favoring the encounter between humans and snakes 36,37,38 .…”

Introduction: Snakebites represent a serious global public health problem, especially in tropical countries. In Brazil, the incidence of snakebites ranges from 19 to 22 thousand cases per 100000 persons annually. The state of Rondônia, in particular, has had an increasing incidence of snakebites. Methods: A retrospective cross-sectional study on snakebites was conducted from January 2007 to December 2018. Brazil's Information System for Notifiable Diseases was queried for all snakebites reported in Porto Velho, Ariquemes, Cacoal, and Vilhena. Data on land surface temperatures during the day and night, precipitation, and humidity were obtained using the Google Earth Engine. A Bayesian time series model was constructed to describe the pattern of snakebites and their relationship with climate data. Results: In total, 6326 snakebites were reported in Rondônia. Accidents were commonly caused by Bothrops sp. (n=2171, 81.80%). Snakebites most frequently occurred in rural areas (n=2271, 85.5%). Men, with a median age of 34 years (n=2101, 79.1%), were the most frequent bitten. Moderate clinical manifestation was the most common outcome of an accident (n=1101, 41.50%). There were clear seasonal patterns with respect to rainfall, humidity, and temperature. Rainfall and land surface temperature during the day or night did not increase the risk of snakebites in any city; however, changes in humidity increased the risk of snakebites in all cities. Conclusion: This study identified the population exposed to snakes and the influence of anthropic and climatic factors on the incidence of snakebites. According to climate data, changes in humidity increased the risk of snakebites.

“…The Achapo system was where it the largest number of individuals of this species was found, what may be due to this system provide a thick leaf-litter layer, favoring species foraging behaviour and reproduction (Rodríguez & Duellman 1994;Haddad & Martins 1994;Duellman 2005;Lötters and Mutschmann 2007;Vásquez et al 2013). The same seems to be the case of the bufonid species A. minuta (Miranda et al 2015;Rojas et al 2015). The Craugastoridae family showed the lowest abundance and richness (only 22 individuals of two species at the community, both exclusive from RF system, see Table 1).…”

We provide information on the diversity of anurans from agroforestry systems in the Colombian Amazon. This area is inserted at the tropical rainforest ecosystem and consists mainly of secondary forest remnants surrounded by crops, grasslands, and agroforestry systems. From February to May 2015, we sampled anurans mainly with visual and auditory surveys. We recorded a total of 1096 individuals of 20 species of anurans from six families at the study area. The relictual forest was the richest environment, followed by Achapo and Cacao agroforestry systems. The Achapo system showed great similarity in species composition with relictual forest, however, the latter presented the highest number of exclusive species, whereas the first presented only two and Cacao system didn't have any exclusive species. Our results show that the richness can vary between the different types of agroforestry systems and highlight their importance as management tool for anurans conservation in the Colombian Amazon.

“…Aditionaly, the political limits and geographic distributions, the existence of cryptic species (Fouquet et al 2007), sampling gaps due to the concentration of researches in a few areas (Azevedo-Ramos and Galatti 2002), sampling effort used appropriate methods for inventories of amphibians (Miranda et al 2015) and problems in various taxonomic groups, frustrate attempts to obtain a comprehensive understanding of Brazil amphibians (Silvano and Segalla 2005). …”

“…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.
