Plant species identity and diversity effects on different trophic levels of nematodes in the soil food web

Article Abstract:

A three-year semi-field experiment was conducted to examine the relation between plant species diversity and the soil food web in which eight plant species were grown in monocultures and mixtures of two, four and eight plant species. Plant species identity affected the abundances of the lower trophic consumer levels more than the higher trophic levels of nematodes.

The interaction between epiphytic algae, a parasitic fungus and Sphagnum as affected by N and P

Article Abstract:

The effects of fertilization with nitrogen (N) and phosphorus (P) on the infection of Sphagnum by its fungal parasite Lyophyllum palustre and the expansion of epiphytic algae are investigated. The impact of increased nitrogen (N) deposition is aggravated by the infection with parasitic fungi and the expansion of epiphytic algae.

How litter quality affects mass loss and N loss from decomposing Sphagnum

Article Abstract:

The effects of litter nitrogen-enrichment on decomposition rates and nitrogen (N) mineralisation for different Sphagnum species in contrasting incubation environments in bogs are investigated. The mass loss and nitrogen loss from litterbags are measured.
