Metabarcoding of Soil Fungal Communities in Rupestrian Grassland Areas Preserved and Degraded by Mining: Implications for Restoration.

Rupestrian grasslands are vegetation complexes of the Cerrado biome (Brazilian savanna), exhibiting simultaneously great biodiversity and important open-pit mining areas. There is a strong demand for the conservation of remaining areas and restoration of degraded. This study evaluated, using next-generation sequencing, the diversity and ecological aspects of soil fungal communities in ferruginous rupestrian grassland areas preserved and degraded by bauxite mining in Brazil.

Gender differences in traditional knowledge of useful plants in a Brazilian community.

Genders differ in traditional ecological knowledge (TEK) about plants, but how gender influences TEK sharing is still poorly understood. Here, we examined how gender is associated with the diversity, transmission, and structure of TEK. We tested whether women and men differ in terms of plant knowledge (species richness, α-diversity), knowledge heterogeneity (β-diversity), and in the structure of social-ecological networks they form.

Monitoring of forest components reveals that exotic tree species are not always invasive in areas under ecological restoration.

Exotic species are known to become invasive in several ecosystems, including areas undergoing restoration. But does that always happen? We monitored the tree layer, seed rain, and regenerating layer of 10-year and 20-year-old forests under restoration in southeast Brazil to verify if planted exotic trees were behaving as invasive; if they were influencing the species richness and abundance of regenerating native plants; and the probabilities of exotic trees perpetuating over time. Data from the three forest components (trees, seed rain, and regenerating) were collected in 12 permanent plots of 100 m each in each study area.
