A literature survey was conducted to determine the amphibian diversity and distribution in Brazilian Amazonia. Patterns of
endemisms and similarity of fauna between localities were also addressed. Twenty-eight inventories were found for the region, the
majority localized in areas with easier access by road or river. A minimum of 163 amphibian species was recorded for Brazilian
Amazonia. Although many species are endemic to the Amazonian lowlands as an entity, the patterns of species uniqueness among
sites suggested low endemic distribution within the lowlands of the Amazon Basin. The mean similarity between localities varied
from low to intermediate (mean=0.40), indicating that the Brazilian Amazonia is characterized by distinctive assemblages of
amphibians throughout its extension. Localities further apart had lower similarity. No threatened species were recorded. These
results contribute to determine priority areas for new inventories and establishment of conservation units. We suggest that areas
next to the Amazon deforestation frontier should be prioritized for new studies due to the high rate of alteration and potential loss
of species. Additionally, studies on amphibian population dynamics are few in Brazilian Amazonia and more of them should be
emphasized to help to draw a better picture of the status of amphibians in this region. # 2001 Elsevier Science Ltd. All rights
