| Abstract |
Belowground biodiversity distribution does not necessarily reflect aboveground biodiversity patterns, but maps of soil biodiversity remain scarce because of limited data availability. Earthworms belong to the most thoroughly studied soil organisms, and - in their role as ecosystem engineers - have a significant impact on ecosystem functioning. We used Species Distribution Modeling (SDMs) and available datasets to map the spatial distribution of commonly observed, i.e., frequently recorded, earthworm species (Annelida, Oligochaeta) across Europe under current and future climate. We showed that earthworm species richness is high in central western and low in north-eastern Europe. This pattern was found to be mainly driven by annual mean temperature and precipitation seasonality, but importance of predictor variables on species occurrences varied among targeted species. Not only geographical ranges of the majority of the earthworm species are predicted to shift to eastern Europe and partly decrease under future climate scenarios, but also were only poorly covered by different protected areas, such as National Parks. Instead, more than 80% of the earthworm range was on average not protected at all (mean = 82.6%, SD 0.04). Overall, our results emphasize the urgency of considering especially vulnerable earthworm species, as well as other soil organisms, in the design of nature conservation measures.
