Species diversity of legumes, grasses and forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…<i>A. caliginosa</i>, Lt…<i>L. terrestris</i>, AcLt…both species) with and without AMF inoculation.

<p>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.</p

Percent root length colonized by AMF of legumes, grasses and non-leguminous forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…only <i>A. caliginosa</i>, Lt…only <i>L. terrestris</i>, AcLt…both species).

<p>Only data from mesocosms inoculated with AMF are shown. Different letters within each row represent significant differences (P<0.05; Tukey-test with sequential Bonferroni correction) between earthworm treatments. Means ± SE, n = 5.</p

Density of legumes, grasses and forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…<i>A. caliginosa</i>, Lt…<i>L. terrestris</i>, AcLt…both species) with and without AMF inoculation.

<p>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.</p

Seedling establishment in mesocosms containing different combinations of earthworm species (NoEw…no earthworms, Ac…<i>A. caliginosa</i>, Lt…<i>L. terrestris</i>, AcLt…both species) without or with AMF inoculation.

<p>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.</p

Biomass production of legumes, grasses and forbs in mescocosms containing different earthworm species (NoEw…no earthworms, Ac…<i>A. caliginosa</i>, Lt…<i>L. terrestris</i>, AcLt…both species) with and without AMF inoculation.

<p>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.</p
