The Chapada das Mesas National Park is a federal reserve located in the State of Maranhão, in an ecotonal region of the Brazilian Northeast Cerrado. Aiming to assess the influence of biogeographic patterns and support restoration actions for regions where information is scarce, we analyzed the floristic composition of savanna and forest Cerrado physiognomies, the floristic relationships with other Brazilian Cerrado areas and investigated the floristic relationships between the Cerrado and the Amazon, and the Caatinga and Atlantic Forest biomes. A total of 242 species in 181 genera and 64 families are recorded in our study. Fabaceae was the most representative family. We report 50 new records of species for Maranhão, four new records for the Cerrado biome and one vulnerable species. The separation of the gallery forest from cerradão and typical cerrado by ordination shows the influence of water availability and soil characteristics on floristic composition. In Cerrado ecotonal regions, such as Mato Grosso and Maranhão, the presence of species shared with the Amazon is expressive. In addition to the Amazon, physiognomies had greater floristic connection with the Caatinga flora. Our data demonstrates that the marginal areas of the Brazilian Cerrado may present high species diversity.

The effects of teleconnections on water and carbon fluxes in the two South America's largest biomes.

Ecosystem services provided by terrestrial biomes, such as moisture recycling and carbon assimilation, are crucial components of the water, energy, and biogeochemical cycles. These biophysical processes are influenced by climate variability driven by distant ocean-atmosphere interactions, commonly referred to as teleconnections. This study aims to identify which teleconnections most significantly affect key biophysical processes in South America's two largest biomes: The Amazon and Cerrado.

We assembled and annotated the complete mitochondrial genomes of (hoary fox), (bush dog), (white-lipped peccary), and (Brazilian free-tailed bat). The mitogenomes exhibited typical vertebrate structures, containing 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and a D-loop region. Phylogenetic reconstruction using the 13 protein-coding genes revealed robust relationships among species within Carnivora, Chiroptera, and Artiodactyla, corroborating previous studies.

Since the establishment of the COVID-19 pandemic, a range of studies have been developed to understand the pathogenesis of SARS-CoV-2 infection, vaccine development, and therapeutic testing. However, the possible impacts that these viruses can have on non-target organisms have been explored little, and our knowledge of the consequences of the COVID-19 pandemic for biota is still very limited. Thus, the current study aimed to address this knowledge gap by evaluating the possible impacts of oral exposure of C57Bl/6 J female mice to SARS-CoV-2 lysate protein (at 20 µg/L) for 30 days, using multiple methods, including behavioral assessments, biochemical analyses, and histopathological examinations.

Pollination service is a global issue with significant impacts on ecosystem maintenance and food production. The decline of bees has highlighted the importance of public awareness and conservation policies to ensure food security and the sustainable use of such services. In this study, we investigated the awareness about bee diversity and pollination services among young students in a medium-sized city in the Cerrado region, the main agricultural frontier in Central Brazil.

Article Synopsis
- Non-human primates (NHPs) in Brazil were studied to investigate the infection rates of Trypanosoma minasense, with a focus on how landscape composition and forest fragmentation affected these rates.
- Sapajus nigritus showed the highest positivity for T. minasense in blood samples (60.9%), while other species like Callithrix spp. and Alouatta guariba clamitans had lower rates, but molecular analysis indicated significant infections in all groups.
- The study found a correlation between T. minasense infections and environmental factors: higher forest fragmentation led to increased infection rates in NHPs, suggesting that habitat loss may drive disease prevalence.
