Abstract. One of the most common conservation strategies used to preserve threatened species is the establishment of protected areas (PAs), providing a maximum representation of biodiversity with the smallest possible cost. The Brazilian Atlantic Forest is one of the 35 global biodiversity hotspots for conservation priorities, having high rate of habitat loss, which is one of the main factors driving threatened amphibians to extinction. Considering that amphibians are the vertebrate group with the largest number of species geographically excluded from global PAs, gap analysis was employed to evaluate whether or not the PAs of the Brazilian Atlantic Forest safeguard the threatened amphibian species in this region. Species status were compared through the official list of threatened species of the Brazilian Fauna and occurrence maps were obtained from the IUCN (International Union for Conservation of Nature) Red List database. Thirty-eight threatened amphibian species were found, accounting for 17 critically endangered (CR), 10 endangered (EN), and 11 vulnerable (VU). The PAs distributed in the Brazilian Atlantic Forest corresponds to only 9 % of the region's entire area. This protected network covers only 30 % of the total geographical range of the assessed species. Besides, a shift in Brazil's environmental policy has led to PAs downgrading. Therefore, the maintenance of PAs integrity is essential, as well as further investment is necessary for the creation of new reserves, avoiding species loss and reducing the extinction risk of the threatened amphibian species in the Brazilian Atlantic Forest.

关于巴西大西洋森林中受威胁两栖动物的保护区网络和保护工作

摘要。用于保护受威胁物种的最常见保护策略之一是建立保护区 (PA)，以尽可能低的成本提供最大的生物多样性代表。巴西大西洋森林是全球 35 个优先保护的生物多样性热点之一，栖息地丧失率很高，这是导致受威胁的两栖动物灭绝的主要因素之一。考虑到两栖动物是在地理上被排除在全球保护区之外物种数量最多的脊椎动物群，采用差距分析来评估巴西大西洋森林保护区是否保护该地区受威胁的两栖动物物种。通过巴西动物群受威胁物种的官方名单比较了物种状况，并从 IUCN（国际自然保护联盟）红色名录数据库中获得了发生地图。发现了 38 种受威胁的两栖动物，其中 17 种极危（CR）、10 种濒危（EN）和 11 种易危（VU）。分布在巴西大西洋森林中的保护区仅占该地区总面积的 9%。这个受保护的网络仅覆盖了评估物种总地理范围的 30%。此外，巴西环境政策的转变导致保护区降级。因此，维护保护区的完整性至关重要，并且需要进一步投资以创建新的储备，
