..Well-conducted forest surveys are an excellent source of data to test for the association between diversity and productivity driven by large-scale environmental factors...

..In contrast, St John's wort reduced ryegrass growth <10%. These results do not support the contention that plants from the introduced range evolve greater competitive ability in the absence of natural enemies...

..In mixed forests, species and functional identity of the trees determine whether litter pools increase with tree diversity...

..While this may lead to denser populations, it does not result in larger plant size in the introduced versus native range as postulated by the ERH...

..In this paper, the importance of the different recruitment stages on population growth is quantified and, thus, the invasion potential of the South African annual geophyte Oxalis pes-caprae invading Mediterranean ecosystems is assessed...

..However, there is little information about the extent to which invasive pollen is incorporated into the pollination network and about the rates of invasive pollen deposition on the stigmas of native plants...

..These results indicate that the introduction of a new species to a community can have important consequences for the structure of the plant-pollinator network...

..Managers also expressed their concern about the fact that much scientific research is concerned with the ecology of alien plants rather than with specific cost-efficient strategies to manage alien species...
