The number and diversity of above-ground arthropods has decreased
significantly over the last 15-20 years, while less is known about
changes in soil biodiversity. Here, we analysed a comprehensive dataset
of soil-living meso- and macrofauna in forests differing in land-use
intensity in three regions in Germany, spanning 12 years from 2008 to
2020. Neither density, species richness nor gamma diversity of soil
fauna declined, suggesting contrasting above- and belowground dynamics
of biodiversity. The community stability of most taxa was not directly
related to forest management, but strongly correlated with asynchrony of
species-fluctuations. However, mainly synchronous fluctuations suggest
that variations of abiotic conditions, such as soil moisture,
overprinted biotic drivers of stability, particularly in soil mesofauna.
While documenting a remarkable resilience of forest soil animals to the
ongoing biodiversity decline, our findings contribute to understanding
the temporal patterns of soil fauna density and diversity and the
drivers of community stability.
