Plant diversity has been shown to increase community biomass in experimental communities, but the mechanisms resulting in such positive biodiversity effects have remained largely unknown. We used a large-scale six-year biodiversity experiment near Jena, Germany, to examine how aboveground community biomass in grasslands is affected by different components(More)

BACKGROUND The different hypotheses proposed to explain positive species richness-productivity relationships, i.e. selection effect and complementarity effect, imply that plant functional characteristics are at the core of a mechanistic understanding of biodiversity effects. METHODOLOGY/PRINCIPAL FINDINGS We used two community-wide measures of plant(More)
The diversity-stability hypothesis states that current losses of biodiversity can impair the ability of an ecosystem to dampen the effect of environmental perturbations on its functioning. Using data from a long-term and comprehensive biodiversity experiment, we quantified the temporal stability of 42 variables characterizing twelve ecological functions in(More)
Nowadays, in a hotly competitive environment, companies are continuously trying to provide products and/or services to customers faster, cheaper, and better than the competitors do. Managers have learned that they cannot do it alone; rather, they must work on a cooperative basis with other organizations in order to succeed. Although the resulting enterprise(More)
In interactive graphics it is often necessary to introduce large changes in the image in response to updated information about the state of the system. Updating the local state immediately would lead to a sudden transient change in the image, which could be perceptually disruptive. However, introducing the correction gradually using smoothing operations(More)
Sensitive Goods (i.e. fruits, vegetables, paper rolls, cellulose) need a special treatment in a logistic environment. For this reason the logistic processes have to be planned in consideration of special transportation conditions. In this context, the existence of possible hazards and chances has to be regarded. In order to handle the existing risks of(More)
BACKGROUND Infiltration is a key process in determining the water balance, but so far effects of earthworms, soil texture, plant species diversity and their interaction on infiltration capacity have not been studied. METHODOLOGY/PRINCIPAL FINDINGS We measured infiltration capacity in subplots with ambient and reduced earthworm density nested in plots of(More)
Modifications of product life cycles, company structures and information flows alter the requirements for logistic processes. Logistic processes are facing new challenges. These developments are caused through the evolution of virtual organisations and the increasing maturity of new ICT technologies like RFID and ubiquitous computing. The rising complexity(More)
BACKGROUND The prevalence of different biotic processes (limiting similarity, weaker competitor exclusion) and historical contingency due to priority effects are in the focus of ongoing discussions about community assembly and non-random functional trait distributions. METHODOLOGY/PRINCIPAL FINDINGS We experimentally manipulated assembly history in a(More)
