Levantamento de anfíbios anuros em duas áreas rurais no Município de Salto do Lontra – Paraná, Brasil

Abstract

Human activities, is constituted in the main cause of the extinction of numerous species of vertebrates. Amphibians because they have specific anatomical features, they are dependent on a conserved habitat and good water quality. For these reasons they are considered bioindicators of environmental quality animals. Inventories species are fundamental for conservation activities of organisms as the first step of the knowledge of the areas. The aim of the study was to survey species of amphibians frogs occurring in two rural areas of the municipality of Salto do Lontra, Paraná, Brazil. The survey was conducted in two rural areas of the municipality. Eight visits were made to field, biweekly frequency, with sampling effort of 40 hours, to carry out sampling, between the months of January to April 2015. Six were selected environments with heterogeneous characteristics between them, differing in hydro periods , systems and marginal vegetation. The survey was conducted from 19h00min to 00h00min. The search for specimens occurred through visual and audio active searches. The vocalization recordings were made with recorder aid, the views recorded by camera. Further identification was held in herpetologico sites, taxonomic guides and scientific papers. In the study were recorded ten species of amphibians, distributed in six families: Centrolinedae, Cycloramphidae, Hylidae, Leiuperidae and Leptodactylidae. The survey of species of amphibians, is the first record of knowledge to anuran fauna of Salto do Lontra Municipality and southwestern Paraná region, adding no remaining data area. The result obtained in the survey is the first knowledge of the species occurring, assisting in the conservation of species and local biodiversity.
