Wildfires and their impact on the water supply of a large neotropical metropolis: A simulation approach.

Hydrological models are powerful tools to simulate the behavior of the water cycle in terrestrial systems and their water interface, including modifications resulting from anthropic activities. In such environments the water stocks depend heavily on the vegetation cover and the ecosystem services derived from it, as part of the interaction soil-plant-topography. Wildfires are disturbances capable of breaking the foundations of these delicate systems.

Check-list of vascular plant communities on ironstone ranges of south-eastern Brazil: dataset for conservation.

Background: Ironstone ranges are considered hotspots for higher plants α and β diversity. The lack of studies and the intense degradation of the ironstone ranges, due to mining, motivated us to compile, for the first time, a list of vascular plants collected on iron-rich derived substrates from ancient landscape of south-eastern Brazil. All existing records in the Brazilian Virtual Herbarium of Flora and Fungi for each of the 43 municipalities containing ironstone ranges were downloaded, resulting in 17,954 vouchers identified to the species level.
