However, adequate integration among empirical approaches (monitoring and experimental) and modelling has rarely been achieved in FBR. We offer an appraisal of the issues involved and chart a course towards enhanced integration. A major element of this path is the joint orientation towards the continuous refinement of a theoretical framework for FBR that links theory testing and generalization with applied research oriented towards the conservation of biodiversity and ecosystem functioning. We further emphasize existing decision-making frameworks as suitable instruments to practically merge these different aims of FBR and bring them into application. This integrated framework requires joint research planning, and should improve communication and stimulate collaboration between modellers and empiricists, thereby overcoming existing reservations and prejudices. The implementation of this integrative research agenda for FBR requires an adaptation in most national and international funding schemes in order to accommodate such joint teams and their more complex structures and data needs. {\\textcopyright} 2013 Gesellschaft f{\\\"{u}}r {\\\"{O}}kologie."],["dc.identifier.doi","10.1016/j.baae.2013.01.001"],["dc.identifier.gro","3148895"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5533"],["dc.language.iso","en"],["dc.notes.intern","Wiegand Crossref Import"],["dc.notes.status","public"],["dc.notes.submitter","chake"],["dc.relation.issn","1439-1791"],["dc.relation.orgunit","Abteilung Ökosystemmodellierung"],["dc.subject.gro","Biodiversity experiments"],["dc.subject.gro","Biodiversity theory"],["dc.subject.gro","Conservation management"],["dc.subject.gro","Decision-making"],["dc.subject.gro","Ecosystem functions and services"],["dc.subject.gro","Forecasting"],["dc.subject.gro","Functional traits"],["dc.subject.gro","Global change"],["dc.subject.gro","Interdisciplinarity"],["dc.subject.gro","Monitoring programmes"],["dc.title","How can we bring together empiricists and modellers in functional biodiversity research?"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Location: Semi-arid savanna in the Kimberley Thorn Bushveld, South Africa. Methods: We developed a two-step protocol for the statistical differentiation of association-promoting mechanisms in plants based on the Acacia erioloba-Grewia flava association. Individuals of the savanna shrub G. flava and the tree A. erioloba were mapped on four study plots. Disentangling the mechanism causing the association of G. flava and A. erioloba involved tests of three spatial and one non-spatial null model. The spatial null models include homogeneous and heterogeneous Poisson processes for spatial randomness based on the bivariate spatial point patterns of the four plots. With the non-spatial analysis, we determined the relationship between the canopy diameter of A. erioloba trees and presence or absence of G. flava shrubs in the tree understorey to find whether shrub presence requires a minimum tree canopy diameter. Results: We first showed a significant positive spatial association of the two species. Thereafter, the non-spatial analysis supported an exclusion of environmental heterogeneity as the sole cause of this positive association. We found a minimum tree size under which no G. flava shrubs occurred. Conclusions: Our two-step analysis showed that it is unlikely that heterogeneous environmental conditions caused the spatial association of A. erioloba and G. flava. Instead, this association may have been caused by seed dispersal and/or facilitation (e.g. caused by hydraulic lift and/or nitrogen fixation by the host tree)."],["dc.identifier.doi","10.1111/j.1654-1103.2011.01310.x"],["dc.identifier.gro","3148928"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5569"],["dc.language.iso","en"],["dc.notes.intern","Wiegand Crossref Import"],["dc.notes.status","public"],["dc.notes.submitter","chake"],["dc.relation.issn","1100-9233"],["dc.relation.orgunit","Abteilung Ökosystemmodellierung"],["dc.subject.gro","Acacia erioloba"],["dc.subject.gro","Grewia flava"],["dc.subject.gro","Plant interactions"],["dc.subject.gro","Spatial association"],["dc.subject.gro","Wiegand-Moloney O-ring statistics"],["dc.title","Disentangling facilitation and seed dispersal from environmental heterogeneity as mechanisms generating associations between savanna plants"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
