The Brazilian anura fauna has 1,039 species, being the most representative. In terms of diversity, Rondonia state has several sub-sampled gaps and it has the highest rates of deforestation in the Amazon. Therefore, the study of the anurans of Pacaas Novos National Park (PNPN), located in Campo Novo of Rondônia, propose to contribute with the biodiversity knowledge of this region. Two areas of the park, upland sites non-subject of flooding and the seasonally flooded areas were sampled in six expeditions carried out during the months of July 2014 to August 2016. Time Limited Visual Search (PVLT) methods, Reproductive Sites (ASR) and Pitfall Traps with Drift Fences (AIQ) were used. The teams used in PVLT and ASR samplings was formed by four or five researchers collecting for two hours/methodology/night, totaling 322 h/man in both ecosystems. Four AIQs (10 pails of 100 Liters) were used with two traps at each area, totaling 340 pails/day/area. During expeditions, 1,571 specimens belonging to 62 species of anurans from thirteen families were recorded: Aromobatidae (5), Bufonidae (4), Centrolenidae (1), Ceratophryidae (1), Craugastoridae (5), Dendrobatidae (2), Hylidae 23), Leptodactylidae (10), Microhylidae (5), Odontophrynidae (1), Phyllomedusidae (3), Pipidae (1) and Ranidae (1). The most frequent family in the park was Hylidae (37.1%). However, Pristimantis fenestratus of the Craugastoridae family was the most abundant species, with 222 specimens recorded (14.13%). The less abundant species (less than 1%) were: Allobates femoralis, Dendropsophus leucophyllatus, D. sarayacuensis, Pristimantis delius, P. diadematus, Teratohyla adenocheira and Trachycephalus cf. cunauaru. The new records for the state were Allobates flaviventris, A. cf. gasconi, Pristimantis delius and P. diadematus. Dendropsophus juliani represented the first record for Brazil. When comparing the richness of two areas, it can be stated that the richness in the seasonally flooded areas is higher in the PNPN, with 18 species that were only found in this area. The richness of PNPN is similar that found in Espigão d'Oeste also located in in Rondonia. / No mundo, foram descritas 7.726 espécies de anfíbios, sendo a ordem Anura a que possui maior número de espécies identificadas com cerca de 6.784 espécies. O Brasil é o país com a maior riqueza da ordem Anura, apresentando o total de 1.039 espécies. O estado de Rondônia apresenta uma das maiores taxas de desmatamento na Amazônia, possuindo várias lacunas sub-amostradas quanto à sua diversidade. Portanto, o estudo dos anuros do Parque Nacional de Pacaás Novos, localizado em Campo Novo de Rondônia, propõem contribuir com o melhor conhecimento quanto a biodiversidade desta região. Foram amostradas duas áreas do parque, uma de floresta de terra firme e a outra de várzea, em seis expedições realizadas durante os meses de julho de 2014 a agosto de 2016, utilizando os métodos de procura visual limitada por tempo (PVLT), amostragem em sítios reprodutivos (ASR) e armadilha de interceptação e queda (AIQ). Para as amostragens de PVLT e ASR, equipe era formada quatro ou cinco pesquisadores coletando durante duas horas/metodologia/noite, totalizando 322 h/observador em ambos ecossistemas. Foram utilizadas quatro AIQ (10 baldes-100L) sendo duas armadilhas em cada base, totalizando 340 baldes/dia/base. Durante as expedições foram registrados 1.571 espécimes, pertencentes a 62 espécies de anuros de 13 famílias: Aromobatidae (5), Bufonidae (4), Centrolenidae (1), Ceratophryidae (1), Craugastoridae (5), Dendrobatidae (2), Hylidae (23), Leptodactylidae (10), Microhylidae (5), Odontophrynidae (1), Phyllomedusidae (3), Pipidae (1) e Ranidae (1). A família de maior ocorrência no parque foi a Hylidae (37,1%). No entanto, Pristimantis fenestratus da família Craugastoridae foi a espécie mais abundante sendo registrados 222 espécimes (14,13%). As espécies menos abundantes (menos de 1%) foram: Allobates femoralis, Dendropsophus leucophyllatus, D. sarayacuensis, Pristimantis delius, P. diadematus, Teratohyla adenocheira, e Trachycephalus cf. cunauaru. Dentre os novos registros para o estado estão Allobates flaviventris, A. cf. gasconi, Pristimantis delius e P. diadematus. Dendropsophus juliani representa o primeiro registro para o Brasil. Quando comparada a riqueza das duas áreas, pode-se afirmar que a riqueza na área de várzea é maior no PNPN, com 18 espécies que foram apenas encontradas nessa área. A riqueza do PNPN é similar a encontrada em Espigão d’Oeste também localizado em Rondônia.

In the group of vertebrates amphibians occupy a prominent place in the number of endemism, with more than half of all species as being unique to that biome. The study was conducted in the Reserva Estadual de Gurjaú (RESG), which is located south of the city of Recife, within the limits of three municipalities (Jaboatão dos Guararapes, Cabo de Santo Agostinho and Moreno). The RESG has a total area of 1,077.10 ha, of which 400 ha are made up of forest areas. Since its inception Pernambuco is administered by the Company of Water and Sanitation (COMPESA), which has a treatment plant installed in the reserve while eliminating its chemical waste downstream of water intake. The frogs during their life cycle are subject to exposure in various types of environment, opposite as important bioindicators of polluted areas and environmentally abused. In order to confirm the harmful effect of disposing of waste in the environment, between January and December 2004 were collected weekly by active search in a 1km stretch of the River Gurjaú, 500m and 500m upstream and downstream of the point of eliminating pollutants. The results show that the 25 species listed for the RESG, six were seen near the river, namely: Hypsiboas semilineatus (Spix, 1824), Leptodactylus gr. marmoratus (Steindachner, 1867), Scinax x-signatus (Spix, 1824), Lithobates palmipes (Spix, 1824), Leptodactylus vastus (Spix, 1824) and Pseudopaludicola gr. falcipes (Hensel, 1867). Comparing the frequency of species in sampling sites with data from biochemical analysis of the water, we can conclude that the discharge of waste made COMPESA characterized by a potentially harmful action to the environment. / Os anfíbios anuros durante seu ciclo de vida estão sujeitos a exposição em diversos tipos de ambientes, contracenando como importantes bioindicadores de áreas poluídas e ambientalmente agredidas. No grupo dos vertebrados, os anfíbios ocupam lugar de destaque em relação ao número de endemismo, apresentando mais de metade do total de espécies como sendo exclusivas do bioma brasileiro mata atlântica. Objetivando confirmar o efeito nocivo da eliminação dos dejetos no ambiente, entre janeiro e dezembro de 2004 foram realizadas coletas semanais por busca ativa, em uma extensão de um (1) km à margem do Rio Gurjaú, sendo 500m a montante e 500m a jusante do ponto de eliminação dos poluentes. O trabalho foi desenvolvido na Reserva Estadual de Gurjaú (RESG), que está localizada ao sul da cidade do Recife, dentro dos limites de três municípios (Jaboatão dos Guararapes, Cabo de Santo Agostinho e Moreno). A RESG possui uma área total de 1.077,10 ha, dos quais 400 ha são compostos por áreas de floresta. Desde a sua criação é administrada pela Companhia Pernambucana de Saneamento e Águas (COMPESA), a qual possui uma estação de tratamento instalada na reserva, que elimina seus dejetos químicos a jusante da captação de água. Os resultados mostram que das 25 espécies listadas para a RESG, seis foram observadas nas proximidades do rio, a saber: Hypsiboas semilineatus (Spix, 1824), Leptodactylus gr. marmoratus (Steindachner, 1867), Scinax x-signatus (Spix, 1824), Lithobates palmipes (Spix, 1824), Leptodactylus vastus (Spix, 1824) e Pseudopaludicola gr. falcipes (Hensel,1867). Comparando a frequência das espécies nos pontos amostrados com os dados de análises bioquímicas da água, podemos concluir que a descarga de resíduos efetuada pela COMPESA caracteriza-se uma ação potencialmente danosa ao ambiente.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Studies of biodiversity surveys and habitat requirements are essential in landscapes threatened by anthropogenic conversion, such as those that make up the Pampa biome. In the present study we determined the spatial distribution of richness of anurans at the Área de Proteção Ambiental (APA) do Ibirapuitã, the largest protected federal area within the Pampa biome in Brazil. Thus we: (1) describe the composition of anuran community regarding species richness, abundance, constancy of occurrence and reproductive modes; (2) compare the frogs composition with other localities of grassland southernmost of South America; (3) tested whether local variables of waterbodies, space and landscape are determinants of species richness, and (4) tested whether environmental heterogeneity influences the structure of anuran community. Sampling was carried from October to November 2012 and at November 2013, the searching at breeding sites method, tadpole collecting and examination of specimens housed in herpetological collections. A total of 64 waterbodies (40 ponds and 24 streams) were sampled for the anuran amphibians, as well as were recorded environmental descriptors in three scales: local, space, and landscape. We recorded the occurrence of 33 anuran species at the APA Ibirapuitã. The registered anurans are typical of open areas, and at least 10% of them are restricted of the grassland areas to the subtropical region of South America, including two endangered species at the global and state levels. Pseudopaludicola falcipes was the most abundant species and Hypsiboas pulchellus was the species most frequently recorded. Five reproductive modes were recorded, and the deposition and the development of exotrophic tadpoles in lentic waterbodies was the most common mode (57.5%). Cluster analysis revealed five groups with more than 50% similarity, whose structure was influenced by geographic distance, but can be partially interpreted by regional peculiarities. We used generalized regression models considering the set of descriptors as predictors of anuran species richness. Subsequently, we use a partition of variance to evaluate the independent and shared explicability between different sets of predictors. Finally, we use a Canonical Redundancy Analysis to explore the role of environmental descriptors on the species abundance of frogs in ponds and streams. The richness in ponds was influenced by the local variable representing the area of waterbodies. Already the abundance was correlated with the percentage of vegetation on the shores and the water temperature. In streams, the species richness of anurans was correlated with a local variable (number of strata of emergent vegetation) and a landscape variable (distance in relation to human residences). Species abundance was affected by higher vegetation strata (> 200 cm) on the shores and by water electrical conductivity. The combined contribution of local and landscape variables have important implications for understanding how amphibians are distributed in the grassland environment. Our work shows the importance of conserving grassland biomes which are increasingly threatened by human activities. / Studies of biodiversity surveys and habitat requirements are essential in landscapes threatened by anthropogenic conversion, such as those that make up the Pampa biome.

Apesar dos habitats de restinga representarem aproximadamente 5.000 km da costa brasileira, o conhecimento disponível sobre a composição da fauna de anuros nestes habitats ainda é restrito a poucas áreas. Estes habitats encontram-se sob intensa pressão imobiliária, com uma densidade demográfica cinco vezes maior do que a média do país, levando a uma ocupação descomedida, degradação e eventual perda destes importantes habitats. Isso é especialmente preocupante para as populações de vertebrados terrestres endêmicos e ameaçados de extinção, devido à dificuldade de recuperação da vegetação das restingas. Atualmente, os remanescentes de restinga ao longo da costa brasileira são representados por fragmentos completamente isolados. Esta é a primeira aproximação da lista de anfíbios da restinga de Grumari, inserida no Parque Natural Municipal de Grumari (PNMG), município do Rio de Janeiro, sudeste do Brasil. É também a primeira pesquisa a analisar a comunidade de anuros de folhiço, e a obter dados de densidade, para as restingas brasileiras. A área está situada no Domínio da Mata Atlântica. O estudo foi conduzido de maio de 2009 a dezembro de 2010 utilizando dois métodos de amostragem: parcelas grandes ou plots de 16 m (4x4 m) e transecções visuais/acústicas. Registramos 22 espécies de anfíbios anuros distribuídas em seis famílias: Leptodactylidae (3), Craugastoridae (1), Bufonidae (1), Strabomantidae (1), Microhylidae (2) e Hylidae (14). Ocorreram dez espécies de anuros de folhiço em 2560 m de chão de floresta amostrados com a metodologia de parcelas grandes durante o estudo. Na zona fechada de pós-praia ocorreram apenas sete espécies de anuros de folhiço, enquanto na mata de restinga ocorreram as dez espécies registradas para a restinga. A densidade geral estimada de anuros de folhiço para a restinga de Grumari foi de 13,1 indivíduos por 100m, superior a cinco de seis estudos publicados com dados de densidade de anuros de folhiço na Mata Atlântica. A biomassa total estimada foi de 13131 g/ha, podendo ser considerada a maior biomassa de anurofauna de folhiço globalmente. Não houve diferença estatisticamente significativa entre as zonas quanto aos parâmetros da comunidade (riqueza, densidade e biomassa), mesmo havendo diferença entre os parâmetros ambientais mensurados nas duas zonas. Os fatores que melhor explicaram a riqueza, a densidade e a biomassa na restinga de Grumari durante a estação chuvosa foram, respectivamente, a temperatura, o diâmetro das árvores/arbustos e o número de árvores/arbustos. A presença de espécies ameaçadas de extinção e endêmicas para o estado do Rio de Janeiro e Mata Atlântica evidencia que a restinga de Grumari é uma área essencial para a conservação da anurofauna dos remanescentes deste habitat no Brasil. Além disso, Grumari é a restinga com maior riqueza de espécies do estado e a segunda maior entre todas as áreas de restinga estudadas até o momento, quanto à anurofauna. / Although restinga habitats represent approximately 5000 km of the Brazilian coast, the information available about the composition of the anuran fauna present on those habitats are restricted to relatively few areas. Nowadays restinga habitats are under intense set of pressures as result of a demographic density five times higher than the average for the country leading to the occupation, degradation and eventual loss of such habitats. This is especially alarming for the threatened endemic populations of terrestrial vertebrates due to the difficulty of vegetation recovery after clearings. Presently, the remnants of these habitats along much of the eastern Brazilian coast are represented by completely isolated fragments. Herein we present the first approximation to the list of the amphibians from the restinga of Grumari, inserted in the Parque Natural Municipal de Grumari (PNMG), municipality of Rio de Janeiro, Rio de Janeiro state, southeastern Brazil. The area is situated in the Atlantic Rainforest Biome. Its also the first study on the community of litter anuran fauna, obtaining density data, for the Brazilian restinga. The study was carried out from May 2009 to December 2010 using two sampling methods: quadrant plots (4x4 m) and acoustic/visual transects. We recorded 22 species of anuran amphibians distributed in six families: Leptodactylidae (3), Craugastoridae (1), Bufonidae (1), Strabomantidae (1), Microhylidae (2) and Hylidae (14). We found ten species of litter frogs in 2560 m of sampled forest floor with the methodology of large plots. In the closed post-beach zone, there were only seven species of anuran leaf litter, while the restinga forest zone present the ten species recorded for the restinga. The overall density of litter frogs at the restinga of Grumari was 13.1 individuals per 100m, more than five of six published studies on the density of litter frogs in the Atlantic Rainforest. The estimated total biomass was 13131 g/100m, being currently the area with highest litter frog biomass on the planet. There was no statistically significant difference between the zones regarding community parameters (richness, density and biomass), even though there is difference between the environmental parameters measured in both zones. The factors that best explained the richness, density and biomass in the restinga of Grumari during the rainy season were, respectively, temperature, diameter of the trees/shrubs and the number of trees/shrubs. The presence of endangered and endemic species indicates that the restinga of Grumari is an important area for conservation of the anuran fauna in remnants of these habitats in the Rio de Janeiro state, being currently the richest known area in terms of amphibian species of all restinga areas in the state, and the second richest of the Brazilian restingas studied up to now.
