Changes in vegetation structure and fuel characteristics along post-fire succession promote alternative stable states and positive fire–vegetation feedbacks
(Wiley Blackwell Publishing, Inc, 2018-03)
Aims: Structural and compositional changes along post-fire succession modify plant community proneness to burn (flammability). The dominant regeneration strategies and life forms, and their interactions along post-fire ...
The diversity of post-fire regeneration strategies in the cerrado ground layer
(2020-01-01)
Disentangling species strategies that confer resilience to natural disturbances is key to conserving and restoring savanna ecosystems. Fire is a recurrent disturbance in savannas, and savanna vegetation is highly adapted ...
Fire effects on the soil seed bank and post-fire resilience of a semi-arid shrubland in central Argentina
(Wiley Blackwell Publishing, Inc, 2018-02)
Soil seed bank is an important source of resilience of plant communities who suffered disturbances. We analysed the effect of an intense fire in the soil seed bank of a semi-arid shrubland of Córdoba Argentina. We asked ...
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 ...
Recuperación de la vegetación post fuego Villa Serrana La Gruta
Fire is a natural disturbance occurring every few years in many grasslands ecosystems. However, since European colonization, fire has been highly reduced or even suppressed in Argentinean grasslands, fostering ignitable ...
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 ...
The importance of fire refugia in the recolonization of a fire-sensitive conifer in northern Patagonia
(Springer, 2018-04)
Seed dispersal and seedling establishment are essential for plant recolonization after disturbances, especially for plants that rely exclusively on sexual reproduction such as post-fire colonizer trees. Fire refugia may ...
Germination response of common annual and perennial forbs to heat shock and smoke treatments in the Chaco Serrano, central Argentina
(Wiley Blackwell Publishing, Inc, 2018-08)
Fire is a key ecological factor affecting plant dynamics. In the last few decades, fire occurrence in the Chaco region has increased noticeably, challenging the adaptive capacity of plants to regenerate after a fire. ...
Fire and legume germination in a tropical savanna: ecological and historical factors
(2019-07-08)
BACKGROUND AND AIMS: In many flammable ecosystems, physically dormant seeds show dormancy-break patterns tied to fire, but the link between heat shock and germination in the tropical savannas of Africa and South America ...
Influence of fire regime on forest structure and restoration of a native forest type in the southern Andean Range
(Chile. Universidad Mayor, 2017)
There is convincing scientific evidence that fire regime has been affected by climate change, both in their frequency and severity, consequently causing more ecological and socio-economic impacts. Although fire has played ...
