Publikováno v: Biogeochemistry. 154:433-449

Conserving soil carbon (C) and harnessing the potential for soil C sequestration requires an improved understanding of the processes through which organic material accumulates in soil. Currently, competing hypotheses exist regarding the dominant mech

Deer browsing effects on temperate forest soil nitrogen cycling shift from positive to negative across fertility gradients

Autor: Knute J. Nadelhoffer, Jacqueline Mechtilde Antoinette Popma

Publikováno v: Canadian Journal of Forest Research. 50:1281-1288

Herbivores impact soil biogeochemical processes, often increasing nutrient cycling rates under high nutrient availability and decreasing nutrient cycling rates under low nutrient availability. These patterns are far from universal, and interactions b

Old-growth forest carbon sinks overestimated

Publikováno v: Gundersen, P, Thybring, E E, Nord-Larsen, T, Vesterdal, L, Nadelhoffer, K J & Johannsen, V K 2021, ' Old-growth forest carbon sinks overestimated ', Nature, vol. 591, no. 7851, pp. E21-E23 . https://doi.org/10.1038/s41586-021-03266-z

Luyssaert et al.1 reported that unmanaged, old-growth forests continue to sequester atmospheric carbon (C) at a rate of 2.4 ± 0.8 Mg C ha–1 yr–1 for stand ages exceeding 200 years. This claim was based on an analysis of net ecosystem productivit

Haber, Callie L Kleinke, Ellen Stuart-Haëntjens, Maxim S. Grigri, Brady S. Hardiman, Lucas E. Nave, Peter S. Curtis, Gil Bohrer, Knute J. Nadelhoffer, Yang Ju

Publikováno v: Ecological Applications. 31

Many secondary deciduous forests of eastern North America are approaching a transition in which mature early-successional trees are declining, resulting in an uncertain future for this century-long carbon (C) sink. We initiated the Forest Accelerated

Multidecadal trajectories of soil chemistry and nutrient availability following cutting vs. burning disturbances in Upper Great Lakes forests

Autor: Knute J. Nadelhoffer, Lucas E. Nave, James M. Le Moine, Christopher M. Gough

Publikováno v: Canadian Journal of Forest Research. 49:731-742

What are the successional trajectories and impacts of disturbances on forest soil nutrient availability? Answers remain elusive because the time scale of interest is long and many factors affect soil properties. We address this question on a regional

Decadal post-fire succession of soil invertebrate communities is dependent on the soil surface properties in a northern temperate forest

Science of the Total Environment, Elsevier, 2019, 647, pp.1058-1068. ⟨10.1016/j.scitotenv.2018.08.041⟩

Although fires are common disturbances in North American forests, the extent to which soil invertebrate assemblages recover from burning remains unclear. Here, we examine long-term (14- to 101-yr) recoveries of soil invertebrate communities from comm

Publikováno v: Frontiers in Environmental Science, Vol 9 (2021)

Protecting existing soil carbon (C) and harnessing the C sequestration potential of soils require an improved understanding of the processes through which soil organic matter accumulates in natural systems. Currently, competing hypotheses exist regar
