Together with Werner Ulrich, Radek Puchałka and Piotr Sewerniak we published paper in Scientific Reports. We used an exceptional data set on central European pine forest understorey plant communities to assess the change in community structure along gradients of soil productivity and heterogeneity. Our results indicate habitat filtering to be the dominant driver of community assembly while competitive interactions have only a minor impact. We found all understorey communities to be significantly nested. The degree of segregation increased with increasing soil Ca and Mg content, as well as with increasing pH, nutrient availability, and moisture. However, variability in soil characteristics did not significantly influence the pattern of species co-occurrence.
