We studied the microbial communities (structure and activity) of the soil system formed by
middens of Lumbricus terrestris and the soil below and surrounding them, and the role of
earthworms in maintaining these structures through time. We set up an experiment in which
middens were either left (control) or removed from their original place (manipulated) and left in
a next area free of worms for 2 months. The transplanted middens were in areas with no evident
signs of earthworm activity (e.g. casts). We took samples of middens, soil below and soil
surrounding (control and manipulated) after 1 and 2 months of manipulation and analyzed the
phospholipid fatty acid (PLFA) profiles and measured respiratory fluxes of CO2 and CH4.
Microbial communities of middens clearly differed from those of soil below and surrounding soil
samples; further, in control middens changes in microbial communities were stronger than in
manipulated middens. Moreover, total PLFAs and bacterial PLFAs (gram negative and positive
bacterial PLFAs) were greater in manipulated than control middens, as well as organic C. This
suggests that earthworms may be competing with microorganisms for C sources, since in organic
C of middens with earthworms decreased with time. Fungi PLFAs were higher in middens and
increased in abundance over time, although abundance was not affected by earthworm
presence. Respiratory fluxes of CO2 were always higher in control middens, revealing the main
role of earthworms in enhancing microbial activity of middens MenosWe studied the microbial communities (structure and activity) of the soil system formed by
