Altitudinal changes in collembolan communities were studied by sampling soil microarthropods along a gradient from 950 to 2150 m a.s.l., under a wide range of forest vegetation types. A multivariate method showed that most changes in species composition followed changes in soil chemistry, humus forms and vegetation. A transition from mull to mor humus, with concomitant soil acidification, was observed with increasing elevation. It was observed that at a given elevation, changes in soil acidity occurring in the course of forest dynamics exerted the same effects than altitude, thus soil acidity explained better the composition of collembolan communities. Densities and local diversity of Collembola were observed to increase with soil acidity, which can be explained by (i) physiological adaptations to acid soils inherited from palaeozoic times and (ii) more habitat and food resources when organic matter accumulates at the top of the soil profile.

- Testate amoebae analysis in ecological and paleoecological studies of wetlands: past, present and future (2008, unknown): “It is not surprising that micro-organisms living in soil or mosses also respond strongly to this gradient if they are analysed in the diVerent habitats (soil type or moss species) found along a climatic gradient, as has usually been the case (Loranger et al. 2001; Todorov 1998).”
- Relationships between land snail assemblage patterns and soil properties in temperate‐humid forest ecosystems (2004, result): “In addition, in contrast to most of the findings on snails, it was demonstrated that densities and local diversity of collembolans increased with soil acidity (Loranger et al., 2001).”
- Collembolan communities as bioindicators of land use intensification (2003, background): “Cyclic changes in the species composition of collembolan communities have been observed to occur at the scale of centuries in near-natural mountain spruce forests, following cyclic changes in soil acidity in the course of vegetation dynamics (Loranger et al., 2001).”
