Acute Physiological Stress and Mortality Following Fire in a Long-Unburned Longleaf Pine Ecosystem
Pages: 1-12
DOI: 10.4996/fireecology.0602001

One important legacy of fire exclusion in ecosystems dependent upon frequent fire is the development of organic soil horizons (forest floor) that can be colonized by fine roots. When fire is re-introduced, the forest floor is often consumed by fire and heavy overstory mortality, often delayed by months, results. We hypothesized that the delayed post-fire tree mortality is a manifestation of a cascade of physiological stresses initiated by root damage that can also magnify the impact of other kinds of damage. We investigated the physiological impact of forest floor consumption on longleaf pines (Pinus palustris Mill.) subjected to a wildfire in 2005 in a long-unburned (> 50 years) forest by measuring forest floor consumption, whole tree water use, and leaf chlorophyll content.  [Read More]

Suites of Fire-Adapted Traits of Oaks in the Southeastern USA: Multiple Strategies for Persistence
Pages: 48-64
DOI: 10.4996/fireecology.1202048

Fire is integral to the functioning of terrestrial ecosystems of the southeastern USA and is a strong selective force on plant species.  Among woody plants, oak species (Quercus spp. L) have diverse life history traits that appear to reflect their evolution in this fire-prone region.  Oaks also occur across wide gradients of fire frequency and intensity, from annually burned savannas to fire-protected forests.  [Read More]
