Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties.

However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, and biomass.

- The study examines how management of agricultural landscapes can help address biodiversity loss in the tropics, focusing on Amazonia.
- Researchers analyzed the impacts of deforestation and land-use changes in six agricultural areas by sampling plants and four animal groups.
- Findings reveal that as agricultural intensification increases, species richness consistently declines, but maintaining over 40% forest cover in these landscapes may help mitigate biodiversity loss.
