▪ Abstract The eutrophication of many ecosystems in recent decades has led to an increased
interest in the ecology of nitrogen transformation. Chemolitho-autotrophic ammonia-…

Nitrification in acid soils was first reported in the beginning of the 20th century. Although this
finding has been well substantiated by countless studies since then, it has until recently …

The phylum Acidobacteria is one of the most widespread and abundant on the planet, yet
remarkably our knowledge of the role of these diverse organisms in the functioning of …

Plants and their arbuscular mycorrhizal fungal symbionts interact in complex underground
networks involving multiple partners. This increases the potential for exploitation and …

Denaturing gradient gel electrophoresis (DGGE) is a powerful and convenient tool for analyzing
the sequence diversity of complex natural microbial populations. DGGE was evaluated …

A coupling of above-ground plant diversity and below-ground microbial diversity has been
implied in studies dedicated to assessing the role of macrophyte diversity on the stability, …

Soil habitats contain vast numbers of microorganisms and harbor a large portion of the
planet's biological diversity. Although high-throughput sequencing technologies continue to …

• The impact of various agricultural practices on soil biodiversity and, in particular, on arbuscular
mycorrhizal fungi (AMF), is still poorly understood, although AMF can provide benefit to …

Rising atmospheric CO 2 levels are predicted to have major consequences on carbon cycling
and the functioning of terrestrial ecosystems. Increased photosynthetic activity is expected, …

To gain insight into the factors driving the structure of bacterial communities in soil, we
applied real-time PCR, PCR-denaturing gradient gel electrophoreses, and phylogenetic …
