Fire as stimulant of shrub recruitment in northwestern Patagonian (Argentina) grasslands
(Springer Tokyo, 2013-06)
One strategy of plant survival during post-fire succession is to persist and regenerate by recruiting new individuals from a fire-resistant seed bank. The heat, smoke, and charcoal released during plant combustion may act ...
FIRE INTENSITY AND SEVERITY IN BRAZILIAN CAMPOS GRASSLANDS
(INTERCIENCIA, 2010)
Brazilian Campos grasslands are rich in species and the maintenance of its diversity and physiognomy is dependent on disturbance (e.g. fire and grazing) Nevertheless, studies about fire intensity and severity are inexistent. ...
Growth and reproductive post-fire responses of two shrubs in semiarid Patagonian grasslands
(Csiro Publishing, 2015-05)
Variation in fire intensity affects the post-fire survival and growth of shrubs. We examined effects of maximum fire temperature (a proxy for fire intensity) on the survival, growth and reproductive performance of the ...
Does fire induce flowering in Brazilian subtropical grasslands?
(Wiley-Blackwell, 2014-10-01)
QuestionsWe aimed to analyse the effect of fire on flowering in subtropical grasslands, by addressing the following questions: will fire history affect flowering? If yes, do fire feedbacks influence flowering or is it just ...
To resist or to germinate? The effect of fire on legume seeds in Brazilian subtropical grasslands
(Soc Botanica Brasil, 2016-01-01)
Fire plays an important role in several grassland ecosystems in the world. Fire can trigger germination in several species, by breaking the physical dormancy of their seeds. Thus, we hypothesized that exposure to high ...
How do the wets burn? Fire behavior and intensity in wet grasslands in the Brazilian savanna
(2017-03-01)
Although wetlands are commonly managed with fire by local communities and managers in tropical savannas, little is known about fire behavior in these ecosystems. We measured fire intensity and temperature in 13 experimental ...
Role of fire on patagonian grasslands: Changes in aboveground vegetation and soil seed bank
(Nova Science Publishers, 2010)
Grasslands are ecosystems dominated by herbaceous and woody vegetation, whose structure is determined by fire, grazing, and drought. Although these structuring factors determine the natural dynamics of grasslands, their ...
Short-term changes caused by fire and mowing in Brazilian Campos grasslands with different long-term fire histories
(Wiley-Blackwell, 2012-06-01)
Questions: What are the main short- term changes in vegetation structure after fire and mowing in Campos grasslands? Are there differences in functional vegetation group responses between sites with diverse fire histories ...
