- Although experiences with ecological restoration continue to accumulate, the effectiveness of restoration for biota remains debated. We complemented a traditional taxonomic analysis approach with information on 56 species traits to uncover the responses of 3 aquatic (fish, macroinvertebrates, macrophytes) and 2 terrestrial (carabid beetles, floodplain vegetation) biotic groups to 43 hydromorphological river restoration projects in Germany. All taxonomic groups responded positively to restoration, as shown by increased taxonomic richness (10–164%) and trait diversity (habitat, dispersal and mobility, size, form, life history, and feeding groups) (15–120%). Responses, however, were stronger for terrestrial than aquatic biota, and, contrary to our expectation, taxonomic responses were stronger than those of traits. Nevertheless, trait analysis provided mechanistic insights into the drivers of community change following restoration. Trait analysis for terrestrial biota indicated restoration success was likely enhanced by lateral connectivity and reestablishment of dynamic processes in the floodplain. The weaker response of aquatic biota suggests recovery was hindered by the persistence of stressors in the aquatic environment, such as degraded water quality, dispersal constraints, and insufficient hydromorphological change. Therefore, river restoration requires combined local- and regional-scale approaches to maximize the response of both aquatic and terrestrial organisms. Due to the contrasting responses of aquatic and terrestrial biota, the planning and assessment of river restoration outcomes should consider effects on both components of riverine landscapes.

- Objective: To develop a scale that measures attitudes towards vaginal birth after caesarean (VBAC) among clinicians. Methods: A cross sectional survey among midwives (n = 58) and obstetricians (n = 51). A 23-item “Hannover Clinicians’ Attitudes towards VBAC scale” (HCAV–scale) was developed. Indicators of reliability and validity were assessed, including item-to-total correlation, Cronbach alpha coefficient and factor analysis. Results: The response rate was 35.3% (n = 109). The HCAV–scale showed high construct validity and high internal consistency. The Cronbach alpha coefficient of the 23 items was 0.87 (n = 89), indicating good internal consistency of the items. Exploratory factor analysis resulted in factor loadings between 0.34 and 0.70; all 23 items loaded above 0.3 on one factor, providing evidence that the scale can be conceptualized as one dimensional. Conclusions: The HCAV–scale is a reliable and valid tool to assess clinicians’ favourable attitudes towards VBAC. The scale can be used to assess how attitudes of clinicians might contribute to institutional variations in VBAC rates, and has the potential to enhance inter-professional understanding and collaboration around VBAC and quality of care for childbearing people with a previous caesarean.
