Fire frequency affects fire behavior in open savannas of the Cerrado
(2021-02-15)
Fire is an environmental factor that helps in shaping plant communities by influencing their structure and function. Frequency is an important component of the fire regime. In tropical savannas, fire frequency is high, ...
How can an invasive grass affect fire behavior in a tropical savanna? A community and individual plant level approach
(Springer, 2015-01-01)
Some invasive grasses have been reported to change fire behavior in invaded plant communities. Urochloa brizantha is an aggressive invasive grass in the Brazilian Cerrado, an ecosystem where fire is a common disturbance. ...
Field-burn vs. fire-related cues: germination from the soil seed bank of a South American temperate grassland
(Cambridge University Press, 2020)
Fire and grazing are large-scale disturbances that shape the structure and function of open habitats. In temperate grasslands of southern South America, fire is used as a management tool to control tussock grasses and ...
Flammability thresholds or flammability gradients? Determinants of fire across savanna–forest transitions
(2020-01-01)
Vegetation–fire feedbacks are important for determining the distribution of forest and savanna. To understand how vegetation structure controls these feedbacks, we quantified flammability across gradients of tree density ...
Post-fire regeneration strategies in a frequently burned Cerrado community
(2021-01-01)
Aim: Fire is a natural disturbance in many ecosystems throughout the world where plant populations can persist by the resprouting of individuals and/or by recruiting from seeds. We evaluated the post-fire regeneration ...
