Sudden oak death: endangering California and Oregon forest ecosystems

had major impacts on forest ecosystems around the world. Classic examples include chestnut blight in North America, caused by Cryphonectria parasitica, and jarrah dieback in western Australia, caused by Phytophthora cinnamomi (Anagnostakis 1987; Weste and Marks 1987). Some exotic diseases, such as chestnut blight and white pine blister rust, have severely impacted populations of a single plant ...

Fuel management practices and their effects on forest and grassland soils of the eastern US

Multiple interacting ecosystem drivers: toward an encompassing hypothesis of oak forest dynamics across eastern North America

Many forests of eastern North American are undergoing a species composition shift in which maples (Acer spp.) are increasingly important while oak (Quercus spp.) regeneration and recruitment has become increasingly scarce. This dynamic in species composition occurs across a large and geographically complex region. The elimination of fire has been postulated as the driver of this dynamic; howeve...
