Soil respiration response to experimental disturbances over 3 years

Creator:

Concilio, Amy, Ma, Siyan, Ryu, Soung-Ryoul, North, Malcolm, and Chen, Jiquan

Abstract:

Soil respiration is a major pathway for carbon cycling in terrestrial ecosystems yet little is known about its response to natural and anthropogenic disturbances. This study examined soil respiration response to prescribed burning and thinning treatments in an old-growth, mixedconifer forest on the western slope of the Sierra Nevada Mountains....

Patterns of mortality in an old-growth mixed-forest of the southern Sierra Nevada, California

Creator:

Smith, Thomas F., Rizzo, David M., and North, Malcolm

Abstract:

Mortality patterns in an old-growth, mixed-conifer forest, in the absence of wildfire, were investigated at the Teakettle Experimental Forest from 2000 to 2002. We tested the hypothesis that after a century of fire suppression, pathogen- and insect-associated mortality (between episodic droughts) would be significantly greater on ingrowth trees (i.e., smaller-diameter,...
