FIRE AND GRAZING IMPACTS ON PLANT DIVERSITY AND ALIEN PLANT INVASIONS IN THE SOUTHERN SIERRA NEVADA
Patterns of native and alien plant diversity in response to disturbance were examined along an elevational gradient in blue oak savanna, chaparral, and coniferous forests. Total species richness,Expand

SMOKE-INDUCED SEED GERMINATION IN CALIFORNIA CHAPARRAL
The California chaparral community has a rich flora of species with different mechanisms for cuing germination to postfire conditions. Heat shock triggers germination of certain species but has noExpand

Determinants of postfire recovery and succession in mediterranean-climate shrublands of California
Evergreen chaparral and semideciduous sage scrub shrublands were studied for five years after fires in order to evaluate hypothesized determinants of postfire recovery and succession. ResidualExpand

Trace Gas Emissions and Smoke-Induced Seed Germination
Dormant seeds of a California chaparral annual were induced to germinate by smoke or paper. Nitrogen oxides induced 100 percent vapors emitted from smoke-treated sand or treated water samplesExpand

ALIEN PLANT DYNAMICS FOLLOWING FIRE IN MEDITERRANEAN-CLIMATE CALIFORNIA SHRUBLANDS
Over 75 species of alien plants were recorded during the first five years after fire in southern California shrublands, most of which were European annuals. Both cover and richness of aliens variedExpand

Mechanism of smoke-induced seed germination in a post-fire chaparral annual
1  Smoke-stimulated germination in the post-fire flora of California chaparral does not appear to be triggered by nitrate. Application of freshly prepared unbuffered KNO3 solutions (pH c. 6.2) failedExpand

Role of Fire in Regeneration from Seed
Fire is a disturbance factor in ecosystems worldwide and affects the reproduction of many plant species. For some species, it is just one of several disturbances that trigger seed germination andExpand

The 2007 Southern California Wildfires: Lessons in Complexity
The 2007 wildfire season in southern California burned over 1,000,000 ac ( 400,000 ha) and included several megafires. We use the 2007 fires as a case study to draw three major lessons aboutExpand

Historic Fire Regime in Southern California Shrublands
Historical variability in fire regime is a conservative indicator of ecosystem sustainability, and thus understanding the natural role of fire in chaparral ecosystems is necessary for proper fireExpand

Demographic patterns of postfire regeneration in Mediterranean-climate shrublands of California
This study uses detailed demographic data to determine the extent to which functional groupings, based on seedling recruitment and resprouting response to fire, capture the dynamics of postfireExpand
