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, ...
Gaps critical for the survival of exposed seeds during Cerrado fires
(2018-01-01)
The fine-scale effects of fire and the consequences for seed survival are poorly understood, especially in the Cerrado (Brazilian savannas). Thus, we investigated whether vegetation gaps (bare soil patches) influence the ...
Quantas vezes devemos queimar o Cerrado? O efeito da frequência do fogo em comunidades vegetais de campo sujo de Cerrado
(Universidade Estadual Paulista (Unesp), 2019-11-29)
O Cerrado é formado por fisionomias campestres e savânicas, evoluiu na presença do fogo e depende dele para manter suas fisionomias e biodiversidade. O regime de fogo influencia diretamente na montagem da comunidade vegetal, ...
Fire and grazing in the Caldenal of Argentina: Effects on plant and soil carbon and nitrogen
(Elsevier Masson, 2007-09)
Fire and grazing can modulate feedbacks between pools of carbon and nitrogen of plant and soil, altering cycles of these elements in grassland ecosystems. The magnitude of these effects may be limited by climate and by ...
Developing a prescription for brush control in the Chaco region, effects of combined treatments on the canopy of three native shrub species
(Taylor & Francis, 2018-07)
Shrub encroachment is frequent in grazing lands in the Chaco region, Argentina. Fire is used by cattlemen to reduce the dominance of the shrub stands, improve forage standing biomass and quality, and enhance grazing ...

Fire regimes shape biodiversity: responses of avian guilds to burned forests in Andean temperate ecosystems of southern Chile
(RESILIENCE ALLIANCE, 2021)
Fire regimes of forests, i.e., time interval, frequency, extent, and severity of fire events, influence structural changes in the vegetation, and thus shape the composition of avian communities. We studied the diversity ...
The relative role of amazonian and non-amazonian fires in building up the aerosol optical depth in south america: A five year study (2005-2009)
(Elsevier Science Inc, 2013-03)
In South America (SA) biomass burning is the major source of atmospheric aerosols. Fires are mostly registered in the dry season (July-November) and are mainly concentrated in the Amazonia and Cerrado regions. Nonetheless, ...
Lidar observation campaign of sugar cane fires and industrial emissions in the State of São Paulo, Brazil
(2010-12-01)
Brazil has an important role in the biomass burning, with the detection of approximately 100,000 burning spots in a single year (2007). Most of these spots occur in the southern part of the Amazon basin during the dry ...
