Bottom-up effects of plant diversity on multitrophic interactions in a biodiversity experiment
It is shown that plant diversity effects dampen with increasing trophic level and degree of omnivory, and the results suggest that plant Diversity has strong bottom-up effects on multitrophic interaction networks, with particularly strong effects on lower trophIC levels. Expand
Differences in the species composition of arbuscular mycorrhizal fungi in spore, root and soil communities in a grassland ecosystem.
A molecular approach was used to analyse the species composition of AMF in spores, intra-radical and extra-radical mycelium in an intensively farmed meadow in central Germany and revealed remarkable differences in the composition ofAMF taxa both between the spores and the mycelia, and between the two types of mycelial taxa.

Niche complementarity for nitrogen: an explanation for the biodiversity and ecosystem functioning relationship?
Testing complementarity nitrogen uptake patterns in terms of space, time, and chemical form as well as N strategies such as soil N use, symbiotic N fixation, or internal N recycling for different plant species suggests that plants occupy distinct niches with respect to their relative N uptake.

Combining nested PCR and restriction digest of the internal transcribed spacer region to characterize arbuscular mycorrhizal fungi on roots from the field
A new method to selectively amplify the internal transcribed spacer (ITS) region of most AMF with a unique primer set based on available sequences of the rDNA is established. Expand
Specific bottom–up effects of arbuscular mycorrhizal fungi across a plant–herbivore–parasitoid system
The study demonstrates that the effects of AMF go beyond a simple amelioration of the plants’ nutritional status and involve rather more complex species-specific cascading effects ofAMF in the food chain that have a strong impact not only on the performance of plants but also on higher trophic levels, such as herbivores and parasitoids.

Species composition of arbuscular mycorrhizal fungi in two mountain meadows with differing management types and levels of plant biodiversity
It seems likely that the AMF species composition, but not necessarily the species number, is related to above ground plant biodiversity in the system under study. Expand
Nitrogen supply affects arbuscular mycorrhizal colonization of Artemisia vulgaris in a phosphate-polluted field site.
It is suggested that N deficiency stimulates root colonization by AMF in this extraordinarily P-rich field site. Expand

The results show that environmental variables hierarchically shape AMF communities and that the sequence type spectrum is strongly affected by previous land use and disturbance, which appears to favor disturbance-tolerant members of the genus Glomus. Expand
Species diversity within the Morchella esculenta group (Ascomycota: Morchellaceae) in Germany and France
This study, based on the polymorphism of the internal transcribed spacer (ITS) region within the nuclear ribosomal DNA (nrDNA), indicates the presence of three distinct species of Morchella esculenta, which can be identified easily by restriction fragment length polymorphisms (RFLP) of the ITS region.

A molecular phylogeny of Hebeloma species from Europe.
In order to widen the scope of existing phylogenies of the ectomycorrhizal agaric genus Hebeloma a total of 53 new rDNA ITS sequences from that genus was generated, augmented by sequences retrieved… Expand
