However, the factors that determined soil CO2 and CH4 fluxes and the extent of the response to fire varied with topography.
They had a fixed loading angle of 6° and their rate of fire varied with the time required to relay the gun.
They had a fixed loading angle of 6° and their rate of fire varied with the time required to re-aim the guns.
The findings on what fuels these fires vary widely because they depend on complex predictions of rainfall: Some areas will have fewer fires since declining rainfall could mean less vegetation growth over the years, and thus less fuel availability.
During the last 165 years of fire reconstruction, neither fire frequency nor percentage of trees scarred by fires varied significantly.
The intensity of the fires varied across the landscape, with a mix of low to moderate severity, and lesser amounts of high burn severity.
The sign of value-dependent changes in tonic firing varied across serotonergic neurons: some increased and others decreased during periods of high state values although, on average, high-value blocks were associated with higher tonic firing rates.
The impact of fire varies spatially and demographically: a seedling in the matrix vegetation has a 95% chance of being killed in a fire, compared with 4% for adult shrubs which largely resprout in the following year.
The standard FWI system tracks only daily levels of fuel moisture and fire behavior potential; however, because some elements of the fire environment vary significantly throughout the day, elements of the AFM system provide ways of adjusting some outputs (i.e., fine fuel moisture code (FFMC), initial spread index (ISI), and fire weather index (FWI)) at different times of day (Van Wagner 1977).
Fire is the principal source of disturbance in fynbos, and fire regimes vary greatly in their season of occurrence, frequency, extent and intensity [11].
