Estudian la frecuencia histórica mensual de los incendios
(INTA, 2022-07-21)
El Instituto de Clima y Agua del INTA, a través de su plataforma SEPA, pone a disposición una herramienta online que permite detectar los meses con mayor frecuencia de focos de calor, en las distintas regiones de la ...
Fire frequency effects on fuel loadings in pine-oak forests of the Madrean Province
Loadings of downed woody fuels in pine-oak forests of the Madrean Province are heavier on sites in southeastern Arizona with low fire frequencies and lower on sites in northeastern Sonora, Mexico, with high fire frequencies. ...
Your best buds are worth protecting: Variation in bud protection in a fire-prone cerrado system
(2021-01-01)
Species growing in fire-prone savannas usually persist by resprouting from their buds. In this study, we evaluated how various persistence traits allow bud protection for improved survival in fire-prone ecosystems. Using ...
Araucaria forest dynamics in relation to fire frequency in southern Brazil based on fossil and modern pollen dataf
(ELSEVIER SCIENCE BV, 2010)
To elucidate the relationship between forest dynamics and fire frequency pollen percentages and charcoal amounts from a 120 cm long peat core and from samples of modern pollen rain were collected along a transect. The study ...
Fire and the reproductive phenology of endangered Madagascar sclerophyllous tapia woodlands
(Elsevier B.V., 2014-09-01)
Tapia woodland vegetation is a remnant of Madagascar sclerophyllous forest that has developed under the selective pressure of fire and is dominated by the endemic tree Uapaca bojeri (Phyllanthaceae), locally named tapia. ...
Non-additive effects of alternative stable states on landscape flammability in NW Patagonia: Fire history and simulation modelling evidence
(Csiro Publishing, 2019-01)
Understanding the relationship between flammability and time since fire (TSF) is crucial for predicting ecosystem responses to changes in fire regimes. Landscapes composed of alternative stable states displaying positive ...
Fire frequency effects on soil and pollinators: what shapes sexual plant reproduction?
(Springer, 2017-09)
Increased fire frequency can significantly erode both soil properties and plant-pollinator interactions affecting plant reproductive success but they have seldom been assessed simultaneously. Here we evaluate soil properties, ...
The effect of simulated heat-shock and daily temperature fluctuations on seed germination of four species from fire-prone ecosystems
(Soc Botanica Brasil, 2016-07-01)
Seed germination in many species from fire-prone ecosystems may be triggered by heat shock and/or temperature fluctuation, and how species respond to such fire-related cues is important to understand post-fire regeneration ...
Frequent fires do not affect sexual expression and reproduction in Vachellia caven
(Wiley Blackwell Publishing, Inc, 2019-06)
In environments with high fire frequency the impoverishment of abiotic resources may favor male sexual expression in plants as it is less costly than female expression. Also, fire can modify pollinator communities and thus ...
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 ...
