This paper examines the sources of uncertainty for the Forced Diffusion (FD) chamber soil
respiration (R[subscript s]) measurement technique and demonstrates a protocol for uncertainty quantification that
could be appropriate with any soil flux technique. Here we sought to quantify and compare the three primary
sources of uncertainty in R[subscript...

quantification of high-frequency
soil respiration using Forced Diffusion chambers
Lavoie, M., Phillips, C. L
This paper examines the sources of uncertainty for the Forced Diffusion (FD) chamber soil respiration (Rs) measurement technique and demonstrates a protocol for uncertainty quantification that could be appropriate with any soil flux technique. Here we sought to quantify and compare the three primary sources of uncertainty in Rs: (1)...
Distinct aggregations of fungal hyphae and rhizomorphs, or "mats", formed by some genera of ectomycorrhizal (EcM) fungi are common features of soils in coniferous forests of the Pacific Northwest. We measured in situ respiration rates of Piloderma mats and neighboring non-mat soils in an old-growth Douglas-fir forest in western Oregon...
While radiocarbon (¹⁴C) abundances in standing stocks of soil carbon have been used to evaluate rates of soil carbon turnover on timescales of several years to centuries, soil-respired ¹⁴CO₂ measurements are an important tool for identifying more immediate responses to disturbance and climate change. Soil Δ¹⁴CO₂ data, however, are often...
The analysis of prehistoric stone features has suffered for two separate but related reasons. The first is the lack of stringency in defining the terms attributed to these structures and, second, the perception of a lack of formal attributes exhibited by them. These two factors have made it impossible to...
Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne’s disease, a chronic granulomatous enteritis that plagues domestic and wild ruminants globally. During the silent stages of Johne’s disease, infected animals intermittently shed bacteria for years prior to clinical diagnosis during advanced disease stages. This strategy allows MAP to...
The object of this study was to observe the effect of tallow plus
urea in vitro and in vivo. The study was carried out in three parts;
an in vitro fermentation study, a metabolism trial and a feedlot trial.
The in vitro study was conducted using a 4 x 2...
