Online-only Table 3.

The information captured in the “species occurrence” data sheet. An observation could refer to a species (either with a scientific binomial or a morphospecies identification), or a genus, life stage, ecological group, or native/non-native group.

Study_Name Text Unique ID for each study. Assigned to all sites within a single study *
Site_Name Text Unique ID given to each site. A site that is sampled in different studies will have the same ID. *
OriginalSpeciesBinomial Text The species binomial of the observation as given by the data collector, prior to revision by earthworm experts
SpeciesBinomial Text The species binomial of the observation (following revision by earthworm experts) At least one required
MorphospeciesID Text An indicator (i.e., number or letter) of a observation that has been only identified to morphospecies
Genus Text The genus of the observation
Family Text The family of the observation
Ecological_group Multiple choice Epigeic, Anecic, Endogeic, Epi-Endogeic, Unknown The ecological group of the observation (following revision by earthworm experts)
LifeStage Multiple choice Adult, Juvenile, Unknown The life stage of the observation
Native/Non-native Multiple choice Native, Non-native, Unknown Whether the observation is native or non-native in the sampled region
Abundance Numerical The total abundance of the observation at a specific site
Abundance Unit Multiple choice Number of individuals, Individuals per cm2, Individuals per cm3, Individuals per m2, Individuals per m3 The units of the abundance value
WetBiomass Numerical The total biomass of the observation at a specific site
WetBiomassUnits Multiple choice g, g/m2 The units of the biomass value

For each dataset, this datasheet was only used if species occurrence data were available.
