Military training effects on belowground biomass, the portion of the plant necessary for recovery, have not been researched exclusively previous to this study. Belowground biomass is inherently difficult to study because of the …

The aims of the study are how above- and belowground woody biomass and organic carbon is accumulated along a chronosequence in South Iceland and how afforested and remnant mountain birch areas react as carbon sinks. In summer 2009, 31 monocormic trees (0.1-5.5 m height) were measured and …

  3. Spatial and Seasonal Patterns of Above- and Belowground Vegetation Biomass and Potential Drivers in the Pascagoula River Delta, MS

    Grimes, Evan2021

    … Pascagoula River contained significantly higher belowground biomass than the East Channel, which is more anthropogenically modified. Vertical distribution of belowground biomass did not strongly vary between seasons or channels. Elevation was significantly correlated to aboveground biomass, and …
