What is Prediction of Species Response to Atmospheric Nitrogen Deposition by Means of Ecological Measures and Life History Traits about?

## Summary The main objective of this study was to predict the responses of vascular plant species to atmospheric nitrogen deposition and enhanced soil nitrogen levels. The study was carried out in deciduous forests located in three regions of southern Sweden. The abundance of vascular plants, as well as soil pH and nitrogen mineralization rates, were studied in a total of 661 sample plots. We calculated an ecological measure (__N~dev~__ value) for all species based on their observed vs. expected nitrification ratios at a given soil pH, and compared its accuracy in predicting abundance changes with results using life history traits. Data from long‐term field studies and fertilization experiments were used for validation. __N~dev~__ values were positively correlated between neighbouring regions. Values for the southernmost region (Skåne) were also positively related to the changes in species frequency observed in large‐scale flora surveys and permanent plot studies in that area and with species changes reported from Central Europe. Values from one of two other regions were also consistent. __N~dev~__ values from Skåne (but no other region) predicted species responses in short‐term f
