Plant and Soil, 1994
Changes in microbial biomass in the rhizosphere of young barley seedlings was studied. A fumigation-extraction (FE) method with measurement of ninhydrin-reactive nitrogen (NR-N) and a substrate-induced respiration (SIR) method were applied on a microscale to rhizosphere soil samples of approximately 0.1 g.

Physiology & Behavior, 1997
The effect of temperature on the metabolism of 10 isolated eyes taken from 5 lake-dwelling specimens of the crayfish Paranephrops planifrons was examined by measuring oxygen uptake and carbon dioxide production at 3 temperatures. The mean values for oxygen utilization at 3 degrees C, 13 degrees C, and 23 degrees C, expressed in microM O2 g-1 min-1 ...

Abstract A substrate-induced respiration (SIR) method is described to measure the contributions of fungi and bacteria to total glucose-induced microbial respiration on plant residues of differing composition. Relationships between fungal, bacterial and total SIR and biomass were used to develop regression equations for predicting microbial biomass C ...

Soil Biology and Biochemistry, 1993
Abstract An incubation experiment was performed with two soils and five pesticide treatments (benomyl, isoproturon, simazine, dinoterb and chloroform). Microbial biomass C and N was estimated by fumigation-extraction (FE). Two modifications of the substrate-induced respiration (SIR) method were used: (1) a continuous flushing system and (2) a static ...

Sub-alpine pasture soils were transplanted from 1400m to three locations along an altitudinal gradient (600-1400m a.s.l) in the Swiss Jura mountains as a climate simulation. Following observations of potential snow-pack effects on in-situ soil respiration along our hill-slope gradient, we collected topsoils from three transplant sites with variable ...
