Contrasting effects of fire frequency on plant traits of three dominant perennial herbs from Chaco Serrano.
(Wiley Blackwell Publishing, Inc, 2016)
Fire frequencies are currently increasing in many regions a cross the world as a result of anthropic activities, affecting ecological processes and plant population dynamics. Fire can generate important changes in soil ...
Changing fire regimes in the temperate rainforest region of southern Chile over the last 16,000 yr
(ELSEVIER, 2008)
A high-resolution macroscopic charcoal record from Lago Melli (42°46′S, 73°33′W) documents the occurrence of forest fires in the lowlands
of Isla Grande de Chiloé, southern Chile, over the last 16,000 yr. Our data suggest ...
Fire-triggered flowering is the dominant post-fire strategy in a tropical savanna
(2021-03-01)
Questions: In fire-prone ecosystems, fire can enhance the flowering and fruiting of many species, a strategy assumed to be well represented in savanna. Despite this, there are surprisingly few studies assessing how prevalent ...
The dynamics of three shrub species in a fire-prone temperate savanna: the interplay between the seed bank, seed rain and fire regime
(Springer, 2013-01)
A model was developed to assess how the seed rain and fire regime affect seed bank dynamics and seedling establishment of three native shrub species (Acanthostyles buniifolius, Baccharis pingraea and Baccharis dracunculifolia) ...
Similarity in Neuronal Firing Regimes across Mammalian Species
(Society for Neuroscience, 2016)
The architectonic subdivisions of the brain are believed to be functional modules, each processing parts of global functions. Previously, we showed that neurons in different regions operate in different firing regimes in ...
Forest connectivity percolation thresholds for fire spread under different weather conditions
(ELSEVIER, 2021)
How fuel influences fire spread at different spatial scales has been broadly studied but it is still under research. Although prior research has generally explored fuel effects at the stand scale, there is increasing ...
Fire-rainfall relationships in Argentine Chaco savannas
(Academic Press Ltd - Elsevier Science Ltd, 2010-10)
We used dendroecological techniques to date fire scars in woody species growing in a subtropical savanna of the Argentine Chaco dry forests, and to explore the temporal trends of fire with rainfall variability at different ...
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 ...
A global synthesis of fire effects on pollinators
(Wiley Blackwell Publishing, Inc, 2019-10)
Understanding fire effects on pollinators is critical in the context of fire regime changes and the global pollination crisis. Through a systematic and quantitative review of the literature, we provide the first global ...
