Respiration rates of roots of loblolly pine (Pinus taeda L.) seedlings decreased in response to elevated ozone (O3 ) concentrations. Estimated annual root respiration rates were 12% less in seedlings exposed to twice-ambient O3 (7 h mean = 70.110 nl 1-1 ) than in seedlings exposed to sub-ambient O3 (7 h mean = 20.40 nl 1-1 ). Measurements taken dur...
Autotrophic nitrifying bacteria are of considerable ecological importance in soils and in the oxygenated zone of sediments. So far, long-term experiments (usually 21-28 days) on the influence of chemicals on nitrification in soils have been carried out by incubation of soil ammended with ammonia and the determination of ammonia, nitrite and nitrate...
A open-flow system capable of regulating wind speed and CO_2 concentration was developed to measure soil respiration. The system consists of infrared gas analyzer (SBP-3 : SHIMAZU), air tank, CO_2 concentration regulator, air pump, flow meter and generator. The system is portable and could be used to measure soil respiration in the field. The effec...
We measured soil respiration during two winters in three different ecotypes of the BOREAS northern study area. The production of CO2was continuous throughout the winter and, when totaled for the winter of 1994–1995, was equivalent to the release of ∼40–55 g C/m2from the soil surface. As soils cooled in the early winter, the CO2 production rate decr...
