Summary: In the Brazilian Cerrado, a weevil induces galls on the leaves of Croton antisyphiliticus, leading to an increased production of extrafloral nectaries on the gall surface. The study found differences in trichome and stomata structures between leaves and galls, with a higher density of trichomes on galls. The overproduction of glands on galls may potentially enhance plant defense against galling insects.

Summary: The study revealed that the Brazilian Cerrado has experienced significant warming trends over the past few decades, with relative humidity decreasing by approximately 15%, potentially leading to a reduction in nocturnal dewfall and impacting the survival of many plants and animals. These climate changes could have a high impact on biodiversity and potentially cause ecosystems to collapse.

Summary: This study evaluated the presence and characteristics of nodulating bacteria in symbiosis with Mimosa spp. and identified Paraburkholderia sp. as the main bacteria present in the nodules. These bacteria effectively nodulated M. pudica but produced ineffective nodules in common bean. The results suggest that this symbiotic relationship may play a role in restoring ultramafic soils degraded by mining activity in Barro Alto areas.

Summary: This study described the cellular features and chemical composition of Agonandra brasiliensis cork and compared it with other cork species. The cork cells of A. brasiliensis are larger and have lower density, with higher lignin content and lower suberin content. The cork of A. brasiliensis differs considerably from other cork species in terms of suberization level, impacting its potential commercial applications towards insulation and low-density products.

Summary: Freshwater ecosystems are crucial for human and wildlife survival, but anthropogenic activities have led to mercury pollution in the Brazilian Savanna ecosystem. The study found that increased land use intensity may result in an accumulation of mercury in sediments and macrophytes over a short period of time.

Summary: The study developed a spatial model of soil 613C in the Cerrado region based on multiple linear regression analysis, showing higher values in the south and lower values in the north. Soil 613C serves as a proxy indicator of vegetation history at the landscape scale for the Central Brazilian savanna, despite some regions where the model could not estimate.

Summary: This study reported the occurrence and genetic characteristics of Theileria spp. in lowland tapirs. Molecular characterization revealed distinct differences between these Theileria spp. and other known Theileria species, suggesting the presence of a new Theileria species in tapirs. Further studies are needed to investigate the biological features and pathogenicity of this newly proposed species.

Summary: The Cerrado is considered the most biodiverse savanna in the world and the second largest Brazilian biome. This study evaluates the degradation dynamics of Cerrado vegetation due to human activity and climate variability. Findings suggest that climatic conditions, forest fires, and agricultural activities are major factors contributing to vegetation degradation, highlighting the need for enhanced conservation and management strategies.

Summary: Areas set aside for conservation within private lands, especially in regions with poor public land protection, such as the Brazilian Cerrado, can effectively enhance biodiversity-friendly landscapes. Private protected areas accommodate a significant percentage of threatened vertebrate species ranges, and their spatial spread benefits a large number of species.

Summary: The green revolution model followed in the Brazilian Cerrado relies on mechanization, chemical fertilization, and the use of herbicides. Paraquat, a non-selective pesticide, is used to kill plants. However, it has toxic effects on wildlife, domesticated animals, human populations, and ecosystems.

Summary: We describe a new phyllocladiferous species, Phyllanthus chapadensis, likely endemic to the Chapada dos Veadeiros region in Goias, Brazil. The region is known for its high number of endemic Angiosperms, unique landscapes, and distinct phytophysiognomies. This new species belongs to a group of Brazilian plants characterized by phylloclades, and it bears resemblance to two species found in the Chapada Diamantina region. However, it can be distinguished based on morphological characteristics of phylloclades and flowers.

Summary: The new species Ruellia umbrosa, found in the riparian forest in the lowlands of Goiás state, Brazil, is described and illustrated in this article. It shares similarities with South American species R. erythropus and R. epallocaulos in terms of stems, flowers, and capsules, but differs in corolla color, presence of bractlets, calyx lobes, and seed characteristics. Due to its small population and environment being heavily impacted by human activities, it is classified as Critically Endangered.
