- 12 July 2008
The area burned in the North American boreal forest is controlled by the frequency of mid-tropospheric blocking highs that cause rapid fuel drying. Climate controls the area burned through changing… Expand
Estimation of temporal variations in historical fire frequency from time-since-fire map data

Dispersal capacity and seed production in anemochorous plants
- D. F. Greene, E. A. Johnson
- Biology, Engineering
- Oecologia
- 1 March 1986
SummarySalisbury has argued that anemochory is less efficient than zoochory. His evidence indicates that zoochores produce fewer seeds and that far dispersing anemochores produce more seeds than do… Expand
Assessing possible shifts in wildfire regimes under a changing climate in mountainous landscapes
- A. Mori, A. Mori, E. A. Johnson
- Environmental Science
- 15 December 2013
Abstract Climate change may affect the probability of extreme events such as wildfires. Although wildfires are some of the most important ecological processes in forest ecosystems, large-scale… Expand
