Carbon concentration of standing and downed woody detritus: Effects of tree taxa, decay class, position, and tissue type

Harmon, Mark E.; Fasth, Becky; Woodall, Christopher W.; Sexton, Jay (Elsevier, 2013-01-07)

The degree to which carbon concentration (CC) of woody detritus varies by tree taxa, stage of decay, tissue type (i.e., bark versus wood), and vertical orientation was examined in samples of 60 tree species from the No ...
Causes and implications of the correlation between forest productivity and tree mortality rates

Stephenson, Nathan L.; van Mantgem, Phillip J.; Bunn, Andrew G.; Bruner, Howard; Harmon, Mark E.; O'Connell, Kari B.; Urban, Dean L.; Franklin, Jerry F. (Ecological Society of America, 2011-11)

At global and regional scales, tree mortality rates are positively correlated with forest net primary productivity (NPP). Yet causes of the correlation are unknown, in spite of potentially profound implications for our u ...
Decomposition of heterogeneous organic matter and its long-term stabilization in soils

Sierra, Carlos A.; Harmon, Mark E.; Perakis, Steven S. (Ecological Society of America, 2011-11)

Soil organic matter is a complex mixture of material with heterogeneous biological, physical, and chemical properties. Decomposition models represent this heterogeneity either as a set of discrete pools with different re ...
