Table 1.
Percent root length colonized by AMF of legumes, grasses and non-leguminous forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…only A. caliginosa, Lt…only L. terrestris, AcLt…both species).
Figure 1.
Seedling establishment in mesocosms containing different combinations of earthworm species (NoEw…no earthworms, Ac…A. caliginosa, Lt…L. terrestris, AcLt…both species) without or with AMF inoculation.
P-Values from repeated measurement ANOVAs, different letters denote significant differences at the end of the measurement period (Tukey, P<0.05). Means, n = 5.
Figure 2.
Species diversity of legumes, grasses and forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…A. caliginosa, Lt…L. terrestris, AcLt…both species) with and without AMF inoculation.
Lower case letters denote differences between earthworm treatments within each plant functional group and AMF treatment; upper case letters denote differences between total plant species diversity (P<0.05). Means, n = 5.

ANOVA results for treatment effects on plant community parameters and microcosm leachate.
Figure 3.
Density of legumes, grasses and forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…A. caliginosa, Lt…L. terrestris, AcLt…both species) with and without AMF inoculation.
Lower case letters represent differences between earthworm treatments within each plant functional group and AMF treatment; upper case letters denote differences between total plant density (P<0.05). Means, n = 5.
Figure 4.
Biomass production of legumes, grasses and forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…A. caliginosa, Lt…L. terrestris, AcLt…both species) with and without AMF inoculation.
Lower case letters denote differences between earthworm treatments within each plant functional group and AMF treatment; upper case letters denote differences between total plant biomass (P<0.05). Means, n = 5.
Figure 5.
Water infiltration, ammonium, nitrate and phosphate leaching in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…A. caliginosa, Lt…L. terrestris, AcLt…both species) with and without AMF inoculation.
Upper case letters denote differences between earthworm treatments; AMF showed no effects (P<0.05). Means ± SE, n = 5.
