[CO2]- and density-dependent competition between grassland species
The predicted ongoing increase of atmospheric carbon dioxide levels is considered to be one of the main threats to biodiversity due to potential changes in biotic interactions. We tested whether effects of intraand interspecific planting density of the calcareous grassland perennials Bromus erectus and Carex flacca change in response to elevated [CO2] (600 ppm) by using factorial combinations o...

متن کاملFungal Community Responses to Past and Future Atmospheric CO2 Differ by Soil Type.
Soils sequester and release substantial atmospheric carbon, but the contribution of fungal communities to soil carbon balance under rising CO2 is not well understood. Soil properties likely mediate these fungal responses but are rarely explored in CO2 experiments. We studied soil fungal communities in a grassland ecosystem exposed to a preindustrial-to-future CO2 gradient (250 to 500 ppm) in a ...
متن کاملSpecies and functional group diversity independently influence biomass accumulation and its response to CO2 and N.
The characteristics of plant assemblages influence ecosystem processes such as biomass accumulation and modulate terrestrial responses to global change factors such as elevated atmospheric CO(2) and N deposition, but covariation between species richness (S) and functional group richness (F) among assemblages obscures the specific role of each in these ecosystem responses. In a 4-year study of g...
متن کاملBiomass and compositional responses of ectomycorrhizal fungal hyphae to elevated CO2 and nitrogen fertilization.
The extramatrical mycelia (EMM) of ectomycorrhizal fungi make up a large proportion of the microbial diversity and biomass in temperate forest soils. Thus, their response to elevated CO(2) can have large effects on plant nutrient acquisition and carbon movement through forests. Here, the effects of CO(2) and nitrogen (N) fertilization on EMM biomass and community structure in Pinus taeda forest...
