Many parts of the Solling Hills have been converted into spruce monoculture stands (Picea abies, which is not native to the region) during the last few centuries. Meanwhile a conversion of pure spruce stands into mixed stands dominated by beech is one of the main goals of silviculture in Germany. The relevés from pure beech and spruce stands as well as mixed beechspruce stands offer good opportunities e.g. to compare composition and diversity of ground layer vegetation in relation to tree species composition or to evaluate the influence of different forest management activities to species diversity.

These approaches are based on the assumption that plants with similar ecologically relevant trait attributes respond to environmental changes in comparable ways. Several methods have been described on how to analyse a priori defined trait sets with respect to environment. Irrespective of the statistical methods used to contrast ecosystem responses and environmental conditions, each functional trait approach depends strongly on the initial trait set. In nearly all recent studies on functional trait analysis a test, if a trait is responsible, is applied independently from the core analysis. In the current study we present a method that extracts those traits from a wider set of traits which are optimal for describing the ecosystem response to a given environmental gradient. This was done by the use of iterative three-table ordination techniques with each possible trait combination. We further concentrated on the effect of the inclusion of too many traits in such analyses. As examples the method was applied to three long term studies on abandoned arable fields. The approach was validated by comparing the results with literature-knowledge on arable field succession. Although the trait pre-selection was only based on a statistical procedure, our method was able to identify all relevant processes of ecosystem responses. All three sites show comparable ecosystem responses; the importance of the competitive ability of plants was highlighted. We further demonstrated that the use of too many traits results in an over-fitting of the trait-environment model. The presented method of iterative RLQ-analyses is adequate to identify responding traits to environmental changes: the discovered processes of successional development of abandoned arable fields are consistent with our knowledge from the literature."],["dc.identifier.doi","10.1111/j.0030-1299.2008.16776.x"],["dc.identifier.isi","000259351700011"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/53278"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0030-1299"],["dc.title","On the identification of the most suitable traits for plant functional trait analyses"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In 1968, initiated by Heinz Ellenberg, an experimental study site was set up on an arable field in the new botanical garden of Gottingen University (Germany). The undisturbed Successions on four plots of a long sere (since 1968/69) and on four additional plots of a shorter sere (since 1982) were evaluated. The seres were classified into stages by cluster analysis, which yield to four Subsequent stages for the long sere and to three Subsequent stages for the short sere. The early succession is characterized by a high proportion of species invasion, whereas with developing time species extinction increased. On all study plots undisturbed Succession directed to the development of pioneer forests. Altogether 247 vascular plant species were recorded. The total species richness shows a fluctuating course during the Successional seres, with significantly increased numbers shortly after Succession has started and a decline in the pioneer-forest stage, when stands age and close down. The primary aim was to compare the characteristics (particular traits) of species occurring at different stages of succession. The majority of the traits concerned exhibited some clear trends in the course of succession. Exclusive reproduction by seeds decreased and the ability for additional vegetative reproduction increased. Anemochorous dispersal significantly decreased, whereas the importance of dispersal by animals, especially endochorous, dominates in the pioneer-forest stage. The mean seed weight significantly increased. During early Succession, plant species staying green over winter dominated, but are of none relevance in the pioneer-forest stage, where summergreen plant species dominate. The change in strategy type features a significant increase of competitive species. The mean Indicator value for light in the herb layer decreased significantly in the pioneer-forest stage.
