          Abstract

          A última lista de espécies do Estado de São Paulo foi atualizada, totalizando 236 espécies de anfíbios, das quais 230 são anuros e seis são Gymnophiona. Foram removidos da lista Bokermannohyla gouveai e Sphaenorhynchus surdus por não ocorrerem no Estado de São Paulo. O número de espécies de anuros registrado representa 27% da riqueza de espécies do país e um aumento de 31% em relação ao número de espécies registradas para o Estado em 1998, demonstrando que, a despeito do Estado de São Paulo ser a região brasileira onde os anuros foram mais estudados, o número de espécies conhecidas deve aumentar nos próximos anos. Foram evidenciadas duas lacunas geográficas importantes: a região sudoeste do Estado, principalmente na bacia hidrográfica do rio Paranapanema e a região nordeste, principalmente na divisa entre os Estados de Minas Gerais e São Paulo. Apesar de ambas terem sido amostradas recentemente, ainda há carência de informações. O estado atual do conhecimento e perspectivas nas áreas de taxonomia, sistemática, ecologia e conservação são avaliados.

          Translated abstract

          The last list of species of the state of São Paulo State was updated and totaled 236 species of amphibians, 230 of which are anurans and six are caecilians. Bokermannohyla gouveai and Sphaenorhynchus surdus were removed from this list, because they did not occur in the State of São Paulo. The number of anuran species recorded comprise 27% of the species richness of the country and an increase by 31% in the number of species recorded for the state since 1998. Thus, despite the State of São Paulo be the Brazilian region where the anurans have been most studied, these data show that the number of known species tends to increase in the next years. We have identified two major geographical gaps of inventory: the southwest of the state, especially in the Paranapanema river basin and the northeast region, mainly at the border between the States of Minas Gerais and São Paulo. Although both have been sampled recently, information is still lacking. The current state of knowledge and perspectives in the areas such as taxonomy, systematics, ecology and conservation are evaluated.

              Declining amphibian populations: the problem of separating human impacts from natural fluctuations.

              Reports of declining amphibian populations in many parts of the world are numerous, but supporting long-term census data are generally unavailable. Census data from 1979 to 1990 for three salamander species and one frog species at a breeding pond in South Carolina showed fluctuations of substantial magnitude in both the size of breeding populations and in recruitment of juveniles. Breeding population sizes exhibited no overall trend in three species and increased in the fourth. Recent droughts account satisfactorily for an increase in recruitment failures. These data illustrate that to distinguish between natural population fluctuations and declines with anthropogenic causes may require long-term studies.
