Fire and pathogen-induced tree mortality are the two dominant forms of disturbance in Western U.S. montane forests. We investigated the consequences of both disturbance types on the controls of microbial activity in soils from 56 plots across a topograph...

The impact of mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Scolytinae), is the most significant source of mortality of mature pine forests in western North America; however, in 2003-2004, high levels of mortality were observed in yo...
