We are no longer updating the Research Digest. All content remains.
The Permaculture Research Digest has summaries of newly published permaculture-related research. All items are hyper-linked to the original publication.
The 'January 2013' archive contains 60 items published in 2012.
Items marked with a # have restricted public access, although abstracts are freely available.
Soil biodiversity plays a key role in regulating the processes that
underpin the delivery of ecosystem goods and services in terrestrial
ecosystems. Agricultural intensification is known to change the
diversity of individual groups of soil biota.This study examined biodiversity in soil food webs from grasslands in Sweden, the UK, the Czech Republic and Greece. It found that land use
intensification reduced the complexity in the soil food webs, as well as
the community-weighted mean body mass of soil fauna. In all regions
across Europe, species richness of earthworms, Collembolans and oribatid
mites was negatively affected by increased land use intensity. Intensive
agriculture reduces soil biodiversity, making soil food webs less
diverse and composed of smaller bodied organisms.
