Atualização do estado de conservação de Limnomedusa macroglossa e Crossodactylus schmidti nos estados do Paraná e Santa Catarina

Abstract

The Red Lists of Threatened Species are very important for government to be able to allocate conservation measures for threatened species. The states of Paraná and Santa Catarina are located in the southern region of Brazil, mostly in the Atlantic Forest biome, classified as a hotspot. In this biome are found more than 600 species of amphibians and many of them are endemic, such as Limnomedusa macroglossa and Crossodactylus schmidti. Following the International Union for Conservation of Nature (IUCN) methodology, with the most current data on the occurrence of the two mentioned species, their occupation area and extent of occurrence in the states of Santa Catarina and Paraná were calculated for a regional assessment. Based on the calculations, L. macroglossa vulnerable was used as a suggestion to classify the range of occurrence and endangered following the occupation area with 3.38% of the extent of occurrence in the state of Paraná. In Santa Catarina, L. macroglossa was classified as vulnerable according to the extent of occurrence criterion and endangered, according to the occupation area criterion, being 2.71% of the extent of occurrence. C. schmidti in Paraná was categorized as least concern in criterion extent of occurrence, by criterion occupation area, this species was classified as vulnerable. In Santa Catarina, this species was classified as critically endangered by criterion extent of occurrence and by criterion occupation area it was classified as critically endangered. The two species have threat classifications in the states, it is necessary to carry out more research to update this classification in the lists.
