Tropical forest structure: Ground measurements of coarse necromass and satellite observations of crown geometry
… canopy density, and coarse woody debris (coarse necromass). Tropical rainforests are structurally the most complex of all ecosystems. In addition to having high biological diversity, Amazon forests are marked by complex vegetation dynamics and a diverse forest stand structures, which play an …

Historical contingency and priority effects impact the decomposition of dead microbial biomass
… the decomposition of dead fungal mycelium (i.e., necromass), a major component of soil carbon (C) and nitrogen (N) in forest soils. In Chapter I, I assessed how fungi and bacteria affected necromass decay using laboratory microcosms. I found that fungi rather than bacteria, drive the early …

Chemical Characterization of the Degradation of Necromass from Four Ascomycete Fungi: Implications for Soil Organic Carbon Turnover and Storage
… And yet, despite growing evidence that microbial necromass, or dead microbial tissue, may be a larger contributor to SOM than previously thought, very little is known about the specific degradation patterns of fungal necromass, and subsequently its potential chemical contributions to long-lived …

Quantifying the immediate carbon emissions from El Niño-mediated wildfires in humid tropical forests
… forests can be considerable owing to high necromass fuel loads. Yet, data on necromass combustion during wildfires are severely lacking. The present study evaluated necromass carbon stocks before and after the 2015– 2016 El Niño in Amazonian forests distributed along a gradient of prior …

The bacterial ecology and function from a sub-surface critical zone
… community capable of utilizing bacterial necromass as a carbon source rather than plant derived carbon. This work has shown for the first time the bacterial diversity of the sub-surface critical zone in this region. Moreover, this bacterial diversity is influenced by plants and the …

Buried Surface Horizons in Saskatchewan Croplands Provide Insight into Microbial Soil Carbon Cycling and Development of Persistent Organic Matter
… quantities and concentrations of microbial necromass (amino sugars) remained in the Ahb vs. Ah horizon but were strongly correlated with clay only in the Ahb horizons (Rho = 0.77, p < 0.001). Further, microbial communities in Ahb horizons were more thermodynamically efficient at utilizing …

… the upper top soils (0-10 cm) depth. Litter C, necromass and thickness were also found to be significantly higher in the afforested sites, while ground vegetation was significantly reduced, but these properties also differed between forest types and with age of the forest. Soil bulk density, pH …
