Such belowground-aboveground interactions are known to depend on the composition of belowground communities, as well as on the plant species that mediates these interactions. However, it is largely unknown whether the effect of belowground communities on aboveground plant-insect interactions also depends on genotypic variation within the plant species that mediates the interaction. To assess whether the outcome of belowground-aboveground interactions can be affected by plant genotype, we selected two white cabbage cultivars [Brassica oleracea L. var. capitata (Brassicaceae)]. From previous studies, it is known that these cultivars differ in their chemistry and belowground and aboveground multitrophic interactions. Belowground, we inoculated soils of the cultivars with either nematodes or microorganisms and included a sterilized soil as a control treatment. Aboveground, we quantified aphid [Brevicoryne brassicae (L.) (Hemiptera: Aphididae)] population development and parasitoid [Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae)] fitness parameters. The cultivar that sustained highest aphid numbers also had the best parasitoid performance. Soil treatment affected aphid population sizes: microorganisms increased aphid population growth. Soil treatments did not affect parasitoid performance. Cultivars differed in their amino acid concentration, leaf relative growth rate, and root, shoot, and phloem glucosinolate composition but showed similar responses of these traits to soil treatments. Consistent with this observation, no interactions were found between cultivar and soil treatment for aphid population growth or parasitoid performance. Overall, the aboveground community was more affected by cultivar, which was associated with glucosinolate profiles, than by soil community."],["dc.description.sponsorship","ERGO, Netherlands Organization for Scientific Research [83806012]"],["dc.identifier.doi","10.1111/j.1570-7458.2011.01123.x"],["dc.identifier.isi","000290686800002"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/22963"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0013-8703"],["dc.title","Effects of soil organisms on aboveground multitrophic interactions are consistent between plant genotypes mediating the interaction"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The diversity of the tree layer can influence herb layer diversity by modifying resource availability and environmental conditions relevant to herb layer plants. Here, we explore the relationship between tree layer diversity and herb layer species richness and cover. Also, we address the question how different environmental factors that are potentially modified by the tree layer influence herb layer characteristics. Our study area is located in the Hainich National Park, one of the largest continuous stretches of broad-leaved deciduous forest in Central Europe. We recorded herb and tree layer composition on 79 plots selected along a tree diversity gradient ranging from two to nine tree species. In addition, canopy cover, soil pH, mass of the humus layer, soil C:N ratio, soil moisture and distance to the forest edge were determined. We used generalized least square models to analyse effects of tree diversity, environmental variables, and spatial plot positions on herb layer species richness and cover. Species richness and cover of the herb layer increased with increasing tree diversity. In addition, both species richness and cover showed a negative response to increasing canopy cover and mass of the humus layer. Herb layer species richness was also positively related to increasing soil pH and the distance to the forest edge. The proportion of forbs increased with increasing tree diversity, whereas the proportion of tree saplings decreased and the proportion of graminoids was not affected. The proportion of true forest species increased with increasing canopy cover. We conclude that forest stands with a high tree diversity feature a more diverse herb layer and a higher herb cover. Furthermore, the environmental variables humus layer mass, light availability and pH also strongly affect herb layer species richness and cover."],["dc.identifier.doi","10.1016/j.ppees.2011.02.004"],["dc.identifier.gro","3150053"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6778"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","1433-8319"],["dc.subject","Understorey diversity; Herbaceous layer; Fagus sylvatica; Canopy cover; Humus layer; pH"],["dc.title","Tree diversity and environmental context predict herb species richness and cover in Germany's largest connected deciduous forest"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
