A first baseline for predictions of future earthworm distribution is provided and the shortage of studies on interacting effects of multiple global change effects on earthworms is revealed, such as potential context-dependent effects of climate change at different soil pollution levels and across ecosystem types. The Earthworm Society of Great Britain and Northern Ireland (ESB) aims to promote and support scientific research so that earthworms and their environment can be better understood. Local earthworm movement responds to a trade-off between food availability and soil water conditions, and this determines the spatiotemporal distribution of the population in the soil profile. Earthworms feed on organic matter present at the soil surface or within the soil. During day time, they live in burrows made by boring and swallowing the soil.

Here, the authors present a mechanistic model of how soil bioturbation and climate interact to predict the global distribution of habitats and associated temporal windows of earthworms. Thus, its distribution in the soil profile is likely to greatly influence earthworm behavior and, in turn, their . Identifying influences of earthworm invasion and distribution in the northern Great Lakes is an important step in predicting the potential extent and impact of earthworms across the region. developed global maps of the distribution of earthworm diversity, abundance, and biomass (see the Perspective by Fierer).
