Like all higher organisms, plants have evolved in the context of a microbial world, shaping
both their evolution and their contemporary ecology. Interactions between plant roots and soil …

Microbial ecology is currently undergoing a revolution, with repercussions spreading
throughout microbiology, ecology and ecosystem science. The rapid accumulation of molecular …

The relationship between desiccation and the production of extracellular polysaccharides (EPS)
by soil bacteria was investigated by using a Pseudomonas species isolated from soil. …

Denitrification, the reduction of the nitrogen (N) oxides, nitrate (NO 3 − ) and nitrite (NO 2 − ),
to the gases nitric oxide (NO), nitrous oxide (N 2 O), and dinitrogen (N 2 ), is important to …

Plant invasions have dramatic aboveground effects on plant community composition, but their
belowground effects remain largely uncharacterized. Soil microorganisms directly interact …

To investigate the potential role of microbial community composition in soil carbon and nitrogen
cycling, we transplanted soil cores between a grassland and a conifer ecosystem in the …

The internal transformations of nitrogen in terrestrial ecosystems exert strong controls over
nitrogen availability to net primary productivity, nitrate leaching into groundwater, and …

Regulation of trace N-gas production via nitrification and denitrification occurs at two levels:(a)
control of the rates of these processes and (b) control of the relative proportions of end …

Soil microorganisms shape global element cycles in life and death. Living soil microorganisms
are a major engine of terrestrial biogeochemistry, driving the turnover of soil organic …

This chapter outlines the methodologies and the concepts used to assess soil internal
nitrogen(N)‐cycle processes. It discusses laboratory and field methods for determining gross and …
