• Explaining density-dependent regulation in earthworm populations using life-history analysis.

• Earthworm casts were negatively related to soil temperatures and positively to moisture content.

• Further experiments are needed to assess costs and benefits of earthworms to plants and ants, as well as to clarify vital aspects of their biology.

• Both species have two main transmission routes, either directly or indirectly, involving paratenic hosts such as rodents or earthworms.

• Variation in soil temperatures and moisture content, respectively, accounted for 97 and 96 % of the variation in earthworm casts.

• The third experiment investigated ant reaction to earthworm mucus.

• In contrast, bird's nests, female insect's oviposition site choices, and the soil transformed by earthworms also modify the environment of the constructor's descendants.
