“…However, despite being a center of endemism and a diversity hotspot for non-volant small mammals (Dalapicolla et al 2021, Delciellos et al 2022, the area of the SBNP located in the municipality of Paraty has been suffering with at least two main anthropic pressures in the last decade that are clearly identifiable. The first is an irregular and diffuse anthropic expansion in the park's surroundings in the municipality of Paraty, quantified by loss of forest cover and an increase in built-up areas or pasturelands (Welerson et al 2021). The second is the paving of the RJ-165 road that crosses the SBNP, which provided increased traffic and vehicle speed, as well as easier access for humans and domestic animals to the park, and an increase in the number of wild animals being run over (Rodrigues 2020, Aguieiras 2021.…”

In the core of the Atlantic Forest biome, the Serra da Bocaina National Park (SBNP) is located in the Atlantic Forest Southeast area of endemism for vertebrates. Filling gaps in knowledge about the spatial distribution and occurrence of species in national parks is of fundamental importance to know how many species are protected and to guide conservation initiatives. Here we updated the non-volant small mammal species list of the SBNP, providing new data on species list and abundance, with species identified mainly by karyotype and/or molecular analysis. Twelve sampling sessions with a capture-mark-recapture approach were carried out in four sites in the SBNP from 2013 to 2016, during the paving works of the state highway RJ-165 (Estrada Parque Paraty-Cunha), municipality of Paraty, state of Rio de Janeiro, Brazil. Non-volant small mammals (Rodentia and Didelphimorphia) were sampled using Sherman® and Tomahawk® live traps (18,987 trap-nights) and pitfall traps (4,591 trap-nights). Thirty-two species (11 marsupials and 21 rodents) were recorded from 1,185 captured specimens. Species richness ranged from 18 to 28 between sites. Ten and 11 species were exclusively captured in live traps and pitfall traps, respectively. The observed richness (32 species) represented 91.4% of the estimated species richness for the study area. Sites 2 and 4 were the most similar to each other regarding species composition, and site 3 was the most dissimilar. The species with highest relative abundance were Euryoryzomys russatus (14%) and Delomys dorsalis (14%), while six species had relative abundances lower than 1%. Fourteen and 17 species were identified by karyotype and molecular analysis, respectively. The present study added 22 species to the park’s non-volant small mammals list, which now has 37 species with confirmed occurrence. This species richness found in the SBNP is one of the highest ever recorded for the group of non-volant small mammals in protected areas of the Atlantic Forest in Brazil, corroborating the Serra da Bocaina region as a biodiversity hotspot.

O Maranhão é o estado brasileiro que faz parte da Amazônia Oriental e possui o menor grau de ocupação do espaço com áreas protegidas gerandoum alto grau de pressão antrópica. Encontra-se entre os estados que mais desmataram a floresta. Este trabalho teve como objetivo analisar as alterações das paisagens, que levam ao desequilíbrio sistémico ambiental, gerado pelo desenvolvimento agropecuário e industrial no município de Açailândia-MA, localizado na Amazônia Oriental brasileira, utilizando ferramentas de geoprocessamento nos anos de 1990, 2000, 2010 e 2020. Os dados foram adquiridos no Instituto Brasileiro de Geografia e Estatísticas (IBGE), Agência Espacial Europeia (ESA), MapBiomas, Imagens do satélite Sentinel-2. Foram construídos mapas de densidade populacional, Índice de Vegetação da Diferença Normatizada (NDVI) e Índice de área verde (IVA). Os resultados demonstram que áreas destinadas a silvicultura sofreram um aumento a partir do ano de 2010, e a Lavouras temporárias foram implementadas significativamente no ano de 2020. A floresta amazônica oriental na região está concentrada em sua maior parte, em áreas de reservas federais, como a do Gurupi. Muito da cobertura vegetal nativa foi perdido, e a atividade antrópica avançou sobre áreas de vegetação natural causando uma mudança no índice de áreas verdes do município.
