The enemy release and EICA hypothesis revisited: incorporating the fundamental difference between specialist and generalist herbivores
The absence of specialist herbivores in invasive populations resulted in the evolution of lower protection against specialists and increased growth and reproduction, but also allowed a shift towards higher protection against generalist herbivore.
Biological Flora of the British Isles: Robinia pseudoacacia
Information is presented on all aspects of the biology of Robinia pseudoacacia L. that are relevant to understanding its ecological characteristics and behaviour and the main topics are presented within the standard framework of the Biological Flora of the British Isles.
Plant diversity effects on soil heterotrophic activity in experimental grassland ecosystems

The presence of nitrogen fixers seemed to be the most important component of the plant diversity manipulation for soil heterotrophs, and reduction in plant biomass due to the simulated loss of plant species had more pronounced effects on voles and earthworms than on microbes.
Numerical responses of different trophic groups of invertebrates to manipulations of plant diversity in grasslands

The similarity of invertebrate responses to plant diversity at the two study sites indicates that general patterns in abundance of different trophic groups can be detected across plant diversity gradients under different environmental conditions.
General stabilizing effects of plant diversity on grassland productivity through population asynchrony and overyielding.
The results suggest that stabilizing effects of diversity on community productivity through population asynchrony and overyielding appear to be general in grassland ecosystems.
Local adaptation enhances performance of common plant species
The overall performance of the three test species, Trifolium pratense, Dactylis glomerata, Plantago lanceolata, was generally highest for plants replanted at their home site and declined with increasing transplanting distance.
ECOSYSTEM EFFECTS OF BIODIVERSITY MANIPULATIONS IN EUROPEAN GRASSLANDS
Results from a multisite analysis of the relationship between plant diversity and ecosystem functioning within the European BIODEPTH network of plant-diversity manipulation experiments largely reinforce the previous results, and those from comparable biodiversity experiments, and extend the generality of diversity–ecosystem functioning relationships to multiple sites, years, and processes.
Do allelopathic compounds in invasive Solidago canadensis s.l. restrain the native European flora?
Seven competing native European plant species were more competitive against the invasive species in soils with activated carbon than without, supporting the allelopathy hypothesis and suggesting lower investment of invasive plants into secondary compounds, possibly because of a higher susceptibility of plant competitors in the invasive range to these substances.
Above-ground resource use increases with plant species richness in experimental grassland ecosystems
It is shown that with increasing diversity, mixtures perform better than the best monoculture, a strong indication that part of the positive effect of diversity on biomass production is driven by complementary resource use.
Root hemiparasites and plant diversity in experimental grassland communities
The hypothesis that the performance of the surviving parasites would benefit from a high functional diversity of hosts was supported, and death of the parasite led to a higher proportion of bare ground in communities when the previously infected communities had low functional diversity, thus enabling subsequent colonization by weeds.
