Disentangling tree species identity and richness effects on the herb layer: first results from a German tree diversity experiment Ghent University
Local neighbourhood tree species composition effects in young forest stands : impact of stress, species identity and multitrophic interactions Ghent University
Effects of drought legacy and tree species admixing on bacterial growth and respiration in a young forest soil upon drying and rewetting Ghent University
Tree neighbourhood-scale variation in topsoil chemistry depends on species identity effects related to litter quality Ghent University
Trees have a large impact on the topsoil chemistry and the strength and direction of this impact depend on the identity of the tree species. Tree species with nutrient-poor litter have the potential to degrade soil fertility, which is characterized by high acidity, low availability of essential nutrients for plant growth, and high levels of available Al and Fe. In contrast, species with more easily decomposing, nutrient-rich litter can ...
Effects of shade tree species on soil biogeochemistry and coffee bean quality in plantation coffee Ghent University
Shade trees are used in many coffee production systems across the globe. Beyond the benefits on biodiversity conservation, climate buffering, carbon sequestration and pathogen regulation, shade trees can impact the soil nutrient status via, for instance, litter inputs and nitrogen fixation. Since soil nutrients affect coffee quality and taste, there is also a potential indirect effect of shade tree species on coffee quality. Yet, in spite of the ...
Contrasting patterns of tree species mixture effects on wood δ13C along an environmental gradient Ghent University
Establishing mixed-species stands is frequently proposed as a strategy to adapt forests to the increasing risk of water scarcity, yet contrasted results have been reported regarding mixing effects on tree drought exposure. To investigate the drivers behind the spatial and temporal variation in water-related mixing effects, we analysed the delta C-13 variation in 22-year tree ring chronologies for beech and pine trees sampled from 17 pure and ...
Legacy effects of tree species diversity on soil properties and seedling performance Ghent University
Forest fragmentation modulates effects of tree species richness and composition on ecosystem multifunctionality Ghent University
Forest fragments in highly disturbed landscapes provide important ecosystem services ranging from acting as biodiversity reservoir to providing timber or regulating hydrology. Managing the tree species richness and composition of these fragments to optimize their functioning and the deliverance of multiple ecosystem services is of great practical relevance. However, both the strength and direction of tree species richness and tree species ...
