New theoretical and analytical approaches have revealed that spatial scale, land-use factors and commu- nity assemblages are important predictors of the relationship between community diversity and invasibility and the negative effects of invasive species on community diversity. In this study we assess if the abundance of Lithobates catesbeianus, the American bullfrog, negatively affects the richness of native amphibian species in Atlantic Forest waterbodies in Brazil. Although this species has been invading Atlantic Forest areas since the 1930s, studies that estimate the invasion effects upon native species diversity are lacking. We developed a model to understand the impact of environmental, spatial and species composition gradients on the relationships between bullfrogs and native species richness. We found a weak positive relationship between bullfrog abundance and species richness in invaded areas. The path model revealed that this is an indirect relationship mediated by community composition gradients. Our results indicate that bullfrogs are more abundant in certain amphibian communities, which can be species-rich. Local factors describing habitat heterogeneity were the main predictors of amphibian species richness and composition and bullfrog abundance. Our results reinforce the important role of habitats in determining both native species diversity and potential invasibility.

    Plano de Manejo ESEC Carijós ENCARTE 5 ANÁLISE DA UNIDADE DE CONSERVAÇÃO 5.1 Caracterização e Diagnóstico do Meio Físico 5.1.1 Clima Por falta de dados da ESEC Carijós e Bacias Hidrográficas, utilizou-se os dados da Estação meteorológica do município vizinho, São José, para caracterização climática da UC e seu entorno. O clima da Ilha de Santa Catarina, conforme KOEPPEN, é classificado como Cfa clima tropical sempre úmido com verões quentes. A dinâmica atmosférica na Ilha de Santa Catarina ocorre por influência de duas massas de alta pressão: o anticiclone polar, centro de ação das massas polares móveis (mPa - fria e úmida) e o anticiclone semi-fixo do Atlântico Sul, centro de ação da massa Tropical Atlântica (mTa - quente e úmida). A atividade da mPa é facilmente identificada pela entrada de frentes frias com ventos intensos do quadrante sul, acompanhada de céu claro após sua passagem. A segunda, mTa, é possível de perceber pela presença dos ventos do quadrante norte predominantes o ano inteiro (MONTEIRO e FURTADO, 1995; NIMER, 1989). Os dados coletados no CLIMERH são referentes às médias mensais máximas e mínimas das condições meteorológicas para Ilha de Santa Catarina. Os valores das precipitações são de 192.1 mm no verão e 81.6 mm no inverno (Figura 5-1 e Tabela 5-1), com média anual de 1.560,5 mm, temperaturas médias de 24.6 ºC no verão e 16.3 ºC no inverno (Figura 5-2 e Tabela 5-1). Os valores médios para a umidade relativa são de 83.8% na primavera e 80.1% no verão (Figura 5-3 e Tabela 5-1), os de velocidade média mensal do vento gira em trono de 11km/h (Figura 5-4) e os de evapotranspiração são de 102,4 mm no verão e 67,6 mm no inverno (Figura 5-5 e Tabela 5-1).

  • Anurans from the Mountain Chain Serra Do Mar: a Critical Area for Amphibian Conservation in the Atlantic Forest, Brazil
    Herpetology Notes, volume 10: 547-560 (2017) (published online on 16 October 2017) Anurans from the mountain chain Serra do Mar: a critical area for amphibian conservation in the Atlantic Forest, Brazil Felipe Siqueira Campos1, 2,* and Ricardo Lourenço-de-Moraes3 Abstract. We present an anuran inventory of the mountain region of the Serra do Mar, Brazil, located in the Atlantic Forest biome. We conducted a fieldwork comprising the major and best well-preserved Atlantic Forest remnants from Brazil, using acoustic and visual nocturnal/diurnal assessments. In total, we recorded 99 anuran species, of which about 70% are endemic to the Atlantic Forest and represent around 20% of all amphibian species described for this biome. The high levels of endemism, the distribution patters and the conservation status of the anuran species turn the mountains of the Serra do Mar into a key conservation region for amphibians within the Atlantic Forest hotspot. Keywords. Amphibia, Atlantic Forest, species inventory, species distribution, conservation. Introduction recognized amphibian species and several more species that still need to be described (Silva and Casteleti, 2003; The Atlantic Forest biome represents one of the Haddad et al., 2013). five most important biodiversity hotspots on Earth The Serra do Mar is a mountain chain that extends (Mittermeier et al., 2011). Originally, it covered around for more than 1,000 km (Almeida and Carneiro, 1998), 1,500,000 km2 of which only about 12% (194,524 km2) stretching from the south of the Espírito Santo state remains in Brazil, Paraguay and Argentina (Ribeiro to the North of the Rio Grande do Sul state (Rizzini, et al., 2009), corresponding to about 100,000 km2 of 1979; Olson et al., 2001).

  • Anurans of Parque Estadual Da Serra Furada, Santa Catarina, Southern Brazil
    Herpetology Notes, volume 10: 287-296 (2017) (published online on 29 May 2017) Anurans of Parque Estadual da Serra Furada, Santa Catarina, Southern Brazil Karoline Ceron1,2,*, Elaine Maria Lucas 3,4 and Jairo José Zocche1 Abstract. We provide a list of amphibians from Parque Estadual da Serra Furada, located in Orleans and Grão-Pará municipalities, in Santa Catarina state, southern Brazil. Monthly sampling was carried out from August 2014 to July 2015, using visual and acoustic surveys. Twenty-seven species of anurans belonging to nine families were recorded on six distinct sites between forest trails, swamps, and streams, with 13 reproductive modes reported. Including all sites, 13 species were abundant, and five of them were considered rare. The greatest richness was recorded in the swamp, while forest trail and stream areas showed the greatest taxonomic distinctness. The high number of reproductive modes is a result of structural characteristics of the sampled areas, providing different microenvironments for anuran reproduction, a characteristic of the Atlantic Forest biome, emphasizing the importance of these environments in amphibian conservation. Keywords: Amphibians, Atlantic Forest, biodiversity, protected area, Neotropical region Introduction 2012).

Seven species groups of Physalaemus are recognized: P. cuvieri group (eight species), P. signifer group (ten species), P. albifrons group (four species), P. deimaticus group (three species), P. gracilis group (five species), P. henselii group (three species), and P. olfersii group (four species). The genus Engystomops Jiménez-de-la-Espada, 1872 is revalidated to include the former P. pustulosus group (sensu Lynch, 1970). It consists of seven species: E. petersi Jiménez-de-la-Espada, 1872 (type-species by monotypy), E. coloradorum (Cannatella & Duellman, 1984), E. guayaco (Ron, Coloma & Cannatella, 2005), E. montubio (Ron, Cannatella & Coloma, 2004), E. pustulatus (Shreve, 1941), E. pustulosus (Cope, 1864), and E. randi (Ron, Cannatella & Coloma, 2004). The genus Eupemphix Steindachner, 1863 is revalidated to include E. nattereri Steindachner, 1864. Key words: Anura. Leptodactylidae. Physalaemus. Engystomops. Eupemphix. RESUMO: Revisão taxonômica dos grupos de espécies do gênero Physalaemus Fitzinger, 1826 com revalidação dos gêneros Engystomops Jiménez-de-la-Espada, 1872 e Eupemphix Steindachner, 1863 (Amphibia, Anura, Leptodactylidae). Os grupos de espécies do gênero Physalaemus são redefinidos com base em características de morfometria, morfologia externa, padrão de desenho e osteologia.

This species has the following three alternative reproductive modes: (1) foam nest on pond and feeding tadpoles in pond (the typical mode for the genus Physalaemus); (2) foam nest on humid places on the forest floor near a pond, and feeding tadpoles in pond; (3) foam nest on water accumulated on the axils of terrestrial bromeliads and feeding tadpoles in pond. These last two modes were not included in the reviews of repro- ductive modes in anurans.
