Nitrification in Dutch heathland soils
TLDR
In this article, the characteristics of nitrification in 41 humus samples of Dutch heathlands were studied and it was shown that nitrification was probably of a chemolithotrophic nature.Abstract:
Some characteristics of nitrification in 41 humus samples of Dutch heathlands were studied Most of the acid humus samples (30) showed accumulation of nitrate during a 4-week incubation of field-moist material In these samples net nitrate production was completely blocked by 006% acetylene indicating that nitrification was probably of a chemolithotrophic nature From a comparison of the net production of nitrate in humus suspensions at pH 4 and pH 6 a differentiation into four patterns could be made:read more

TL;DR: Ecosystems thought of as not N limited, such as tropical and subtropical systems, may be more vulnerable in the regeneration phase, in situations where heterogeneity in N availability is reduced by atmospheric N deposition, on sandy soils, or in montane areas.

The effects of air‐borne nitrogen pollutants on species diversity in natural and semi‐natural European vegetation
TL;DR: In this article, the effects of increased atmospheric nitrogen inputs, from both NOy and NHx, on diversity in various semi-natural and natural ecosystems are reviewed and the severity of these impacts depends on abiotic conditions (eg buffering capacity, soil nutrient status and soil factors that influence the nitrification potential and nitrogen immobilization rate) in the particular system.

TL;DR: In this paper, the authors measured the microbial and chemical characteristics of the soils under different tree species and found that there were differences in N transformations under pine, spruce and birch, but the changes depended also on the fertility of the site.

TL;DR: In this article, the authors collected soil samples from the litter, humus and five mineral soil layers to a depth of 50 cm in acid, but highly productive, Norway spruce forests in S Sweden and E Denmark for determination of net N mineralization and potential nitrification.

Regulation of cytoplasmic pH in bacteria.
TL;DR: The aim of this review of pH homeostasis in bacteria is to assess the role of transport systems in the regulation of cytoplasmic pH and to consider the principal questions which remain to be answered.

TL;DR: The lack of inhibitors specific for one or the other of the two groups of bacteria hampers the determination of their relative roles in nature.
