Brazil is the world's richest country in biodiversity, including mammal species. In the Brazilian Cerrado biome, mammalian diversity is vast, with about 251 species, 32 of them are endemic and 22 listed as threatened species. In this work, we investigated species diversity of medium- and large-sized mammals in the private protected area RPPN Pontal do Jaburu (RPPN-PJ) and its surroundings, which is a flooded area located in an important biological corridor in the Cerrado-Amazon ecotone zone, a priority area for biodiversity conservation in Brazil. We used camera-trapping, active search (night and day), and track survey during dry season (Apr – Aug 2016). We recorded 29 mammal species, being the Carnivora order the most representative with 11 species. Regarding threat status, 35.7% of the recorded species were listed as threatened in Brazil and 32.1% worldwide. We highlight the high relative frequency of threatened species records such as Tapirus terrestris, Panthera onca, Blastocerus dichotomus, Pteronura brasiliensis, Priodontes maximus, and other, as well as the presence of the newly described aquatic mammal species Inia araguaiaensis. We stress the importance of RPPN-PJ and its surroundings for mammal conservation, which include complex habitats (wetlands) located in an important ecotone zone.

This study evaluates the reproductive and ecological similarity between loggerhead sea turtle (Caretta caretta) and Hawksbill sea turtle (Eretmochelys imbricata) two species of sea turtles on the southern coast of Bahia (Brazil) during two breeding seasons (October to April 2013 to 2015). The study covers a 10-km area composed of three beaches, Pompilho, Itacarezinho and Patizeiro beach, which are 5, 3, and 2 km long, respectively. Daily field surveys were performed for 102 days to assess patterns between the studied species, using the non-metric multidimensional scaling order and the Spearman correlation analysis to obtain the oviposition pattern of the two species. Moreover, Kruskall-Wallys tests were performed to review the differences in the number of hatchlings on the three beaches. The NMDS proved the species are very similar from an ecological perspective since as there were three clear groupings in terms of the number of hatchlings on the three beaches. With reference to the number of nests, a negative correlation was observed in the two species. Regarding the hatching activity of both species on the three beaches studied, a larger amount of C. caretta and E. imbricata hatchlings was found on Pompilho beach, followed by Patizeiro and Itacarézinho. These findings influence management strategies to reduce anthropogenic impact and contribute to the conservation of these two endangered sea turtle species.

No abstract

O Brasil apresenta uma imensa diversidade étnica, linguística e cultural e apesar do grande número de comunidades quilombolas no Brasil, essas ainda sofrem por descaso e falta de reconhecimento de suas terras, aumentando ainda mais os problemas sociais enfrentados por essas comunidades como o acesso à saúde e saneamento básico. Do ponto de vista ambiental, as comunidades tradicionais em geral são bem preservadas devido à grande relação dessas comunidades com a natureza, onde cada espécie de planta, grupo de animais, tipo de solo e paisagem possui um uso prático ou religioso. Ações de educação ambiental tem se tornado uma ferramenta importante na busca pela identificação cultural e preservação da natureza das comunidades quilombolas. Apesar disso, poucos estudos ainda vêm sendo publicados a respeito dessas ações, dificultando a identificação de lacunas com relação às comunidades quilombolas menos assistidos. O presente trabalho buscou identificar quantitativamente os estudos de educação ambiental realizados em comunidades quilombolas. Foram realizadas buscas na plataforma Google Scholar por meio das seguintes palavras-chave: “Quilombolas”, “Educação Ambiental” e “Comunidades tradicionais”. Foram encontrados 65 estudos, sendo a maior parte do tipo artigo científico em revistas de qualidade intermediária. A comunidade Quilombola Mata-Cavalo localizada às margens da BR-MT 060 no Estado do Mato Grosso-MT, foi a mais estudada e o ano com maior número de publicações foi 2018. Os temas dos estudos encontrados foram bastante variáveis, demonstrando o caráter multidisciplinar da educação ambiental e realizados em sua maioria por universidades públicas, demonstrando a importância da valorização dessas instituições.

Interactions between predator and prey are important components for the structuring of terrestrial communities. Anurans are considered the main food item for snakes. Xenopholis scalaris has a wide geographic distribution, occupying the Amazon Forest and Atlantic Forest, inhabiting primary and secondary forests in humid environments. Anurans are one of the main food items that make up its diet. Other studies have reported unsuccessful predation attempts of this species on frogs of the family Leptodactylidae. The frog Physalaemus erikae is an endemic species from the southern region of Bahia state, eastern Brazil, occupying habitats on the edge of the Atlantic Forest, clearings, and cocoa plantations (Cabrucas). The case of the unsuccessful attempt at predation on the species involved in the event described here may be due to the size of the prey and the prey's ability to strongly resist the predator's capture.
