Greenbelts do not reduce NO2 concentrations in near-road environments
TL;DR: In this article, the influence of greenbelt-type forest patches on NO2 levels (i) in front of, (ii) inside and (iii) behind greenbelts next to major roads in the Helsinki Metropolitan Area, Finland, during summer and winter using passive collectors.
Journal ArticleDOI
Role of the fauna in soil processes: techniques using simulated forest floor
TL;DR: In this paper, the influence of soil animals on processes such as decomposition, nutrient cycling, and plant growth in northern coniferous forests was investigated using simulation of a complex pattern of forest floor, controlled air flow through the systems and automatic measurement of carbon flows.
Journal ArticleDOI
Nonparasitic Nematoda provide evidence for a linear response of functionally important soil biota to increasing livestock density.
TL;DR: It is argued that in intensive agroecosystems, other fungivore members of the decomposer food web may outcompete the hyphal-feeding nematodes, and the use of the fifth percentile as proxy for a sustainable environmental quality of grasslands on sandy soils and the NCR mean as the upper threshold for low-stocked farms is proposed.
Journal ArticleDOI
Do plant species of different resource qualities form dissimilar energy channels below-ground
Christina Witt,Heikki Setälä +1 more
TL;DR: It is found that plant species can, in a relatively short time, modify the composition of the soil decomposer community and find a clearly separated root energy channel under the legume L. corniculatus.
Journal ArticleDOI
Over twenty years farmland reforestation decreases fungal diversity of soils, but stimulates the return of ectomycorrhizal fungal communities
Nan Hui,Xinxin Liu,Ari Jumpponen,Heikki Setälä,D. Johan Kotze,Liliya Biktasheva,Martin Romantschuk,Martin Romantschuk +7 more
TL;DR: The ability of fungi grown in previously strongly managed agricultural land to rapidly respond to reforestation and thus provide support for forest trees is highlighted, and the ability of fungal communities that were still in transition to be restored.
