Uncertainty Assessment In Biomass Estimation, Isaac Lisle May 2018

Uncertainty Assessment In Biomass Estimation, Isaac Lisle

Isaac Lisle

Carbon stock is the carbon stored in one of the major phases of the carbon cycle, and flux is the movement of carbon between these phases. This study will use a similar model to one previously developed by Gonzalez et al. (2015) to estimate carbon stock and flux in the aboveground living biomass of the State of California and evaluate the uncertainty associated with these estimations. It is important to understand the methods involved in calculating carbon stock and the accompanying uncertainty to determine the best uses for mapping products of forest biomass in California, which is directed by California …

Differential Effects Of Canopy Trimming And Litter Deposition On Litterfall And Nutrient Dynamics In A Wet Subtropical Forest, Steven J. Hall, Whendee L. Silver, Grizelle González Nov 2014

Differential Effects Of Canopy Trimming And Litter Deposition On Litterfall And Nutrient Dynamics In A Wet Subtropical Forest, Steven J. Hall, Whendee L. Silver, Grizelle González

Steven J. Hall

Humid tropical forests have the highest rates of litterfall production globally, which fuels rapid nutrient recycling and high net ecosystem production. Severe storm events significantly alter patterns in litterfall mass and nutrient dynamics through a combination of canopy disturbance and litter deposition. In this study, we used a large-scale long-term manipulation experiment to explore the separate and combined effects of canopy trimming and litter deposition on litterfall rates and litter nutrient concentrations and content. The deposition of fine litter associated with the treatments was equivalent to more than two times the annual fine litterfall mass and nutrient content in control …
