How does ecosystem function change in response to fire and clear-cutting?
Byrd, K.B., Parker, V.T., Vogler, D.R., and K.W. Cullings (2000) The influence of clear-cutting on ectomycorrhizal fungus diversity in a Lodgepole pine (Pinus contorta) stand, Yellowstone National Park, Wyoming, and Gallatin National Forest, Montana. Canadian Journal of Botany 78:149-156.

 

How does ecosystem function change when diseases spread in response to global climate change?
Cullings, K.W., Ishkhanova, G., and J. Henson. 2008. Defoliation effects on enzyme activities of the ectomycorrhizal fungus Suillus granulatus in a Pinus contorta (lodgepole pine) stand in Yellowstone National Park. Oecologia 158(1): 1432-1439.

Cullings. K.W., Raleigh, C., and D. Vogler. 2005. Effects of severe dwarf mistletoe infection on the ectomycorrhizal community of lodgepole pine in Yellowstone Park. Canadian Journal of Botany 83(9):1174-1180.

 

How does species diversity moderate the effects of environmental change?
Cullings, K.W., Vogler, D.R., Parker, V.T., and Makhija, S. (2001) Defoliation effects on the ectomycorrhizal community of a mixed Pinus contorta/Picea engelmannii stand in Yellowstone Park. Oecologia (Berlin) 127(4): 533-539.
