    Phylogenetic analyses based on nLSU and ITS sequence data indicate that the sequestrate genus Gigasperma is polyphyletic. Gigasperma cryptica, which is known only from New Zealand, has affinities with the Cortinariaceae ...
  • Decadal Trends in Net Ecosystem Production and Net Ecosystem Carbon Balance for a Regional Socioecological System 
    Turner, David P.; Ritts, William D.; Yang, Zhiqiang; Kennedy, Robert E.; Cohen, Warren B.; Duane, Maureen V.; Thornton, Peter E.; Law, Beverly E. (Elsevier, 2011)
    Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes − notably by way of harvest removals and related impacts on net ecosy ...
  • Decomposition of heterogeneous organic matter and its long-term stabilization in soils
