Resumo

In this study, we summarize the available information about the invasion of the Lithobates catesbeianus in the Paraná state, Brazil, through search for published papers and inventory of the municipalities of the State that has active commercial frog farms. Occurrence of the L. catesbeianus in nature was recorded in eight studies and in 15 localities in the Paraná. We found a total of the 19 municipalities in the Paraná having commercial frog farms.The records of the L. catesbeianus invasions are relatively spread along of the Paraná. We encountered that from of the 15 records of the L. catesbeianus as invasive in 86.7% (or 13 from 15) of them were located at distances below 50km from the nearest municipality having frog farm, one were established at a distance of about 80km and one at a distance of approximately 130km from de nearest municipality having frog farm. These data suggest a consistent relationship of the occurrence of frog farms and the records of the invasions by L. catesbeianus along the geographic space of the Paraná state.


Neste estudo, nós reunimos informações disponíveis sobre a invasão de Lithobates catesbeianus no estado do Paraná no Brasil, através de trabalhos publicados e de um inventário dos municípios do Estado que tenham ranários ativos. A ocorrência de L. catesbeianus na natureza foi registrada em oito estudos e em 15 localidades no Paraná. Nós encontramos um total de 19 municípios no Paraná com ranários. Os registros de Lithobates catesbeianus estão relativamente espalhados ao longo do Paraná. Nós encontramos que dos 15 registros de L. catesbeianus como invasor, 86.7% (ou 13 de 15) deles ocorreram em locais com distâncias inferiores a 50km do município mais próximo possuindo fazenda comercial de criação de rãs, um deles estava a uma distância de cerca de 80km de município com criadouros e o outro a uma distância de aproximadamente 130km do município mais próximo possuindo criadouro. Estes dados sugerem uma relação consistente da ocorrência de ranários e os registros de invasões por L. catesbeianus ao longo do espaço geográfico do estado do Paraná.

Resumo

In this study we provide the first data regarding community parameters of leaf-litter anurans inhabiting a forest floor in the state of Paraná, southern Brazil, including information on community species richness, composition, specific density and biomass. Our study was conducted at Salto Morato Natural Reserve using forty plots of 4 x 4 m for each one of the four seasons (winter, spring, summer and autumn), totaling 2.560 m² of forest floor sampled. We sampled a total of 96 frogs inhabiting the forest floor, belonging to seven species: Brachycephalus hermogenesi (Giaretta & Sawaya, 1998), Ischnocnema guentheri (Steindachner, 1864), Haddadus binotatus (Spix, 1824), Leptodactylus gr. marmoratus, Physalaemus spiniger (Miranda-Ribeiro, 1926), Proceratophrys boiei (Wied-Neuwied, 1824), and Rhinella abei (Baldissera, Caramaschi & Haddad, 2004). The overall frog density in the forest floor was 3.73 ind/100m², with I. guentheri (1.37 ind/100 m²) being the most common species and R. abei (0.19 ind/100 m²), the rarest. The estimated overall frog mass in the community was 3.29 g. The abundance, richness and density varied consistently among the four seasons sampled, with the highest values occurring in the spring and summer seasons.
