Charcoal analysis of lake sediments is used to reconstruct long-term variations in fire
occurrence that can complement and extend reconstructions provided by …

Little question exists that the main bodies of North American prairie (ie, the tall‐grass, mixed,
and shortgrass) are among the most endangered resources on the continent. The purpose …

Land managers are grappling with massive changes in vegetation structure, particularly in
protected areas formerly subjected to fire and grazing. The objective of this review was to …

Many species of birds that depend on grassland or savanna habitats have shown
substantial overall population declines in North America. To understand the causes of these …

Recensuses of 54 Wisconsin prairie remnants showed that 8 to 60 percent of the original
plant species were lost from individual remnants over a 32-to 52-year period. The pattern of …

With the increase in global wildfire activity in response to global climate warming, the
reconstruction of long-term fire histories and their links to environmental and anthropogenic …

A multitrophic model integrating the effects of flooding disturbance and food web interactions
in rivers predicted that removing floods would cause increases of predator-resistant grazing …

Study of microscopic charcoal from lake sediments has led to a greater understanding of
past veg etation, climate and fire ecology. We investigated the potential of charcoal …

Rapid changes in wildfire patterns are documented globally, increasing pressure to identify
regions that may experience increases in wildfire in future decades. Temperate grassland …

Fire use has played an important role in human evolution and subsequent dispersals across
the globe, yet the relative importance of human activity and climate on fire regimes is …
