The ERH is popularly cited to explain the invasive properties of many species and is the(More)
During the past century, the biomass of woody species has increased in many grassland and savanna ecosystems. As many of these species fix nitrogen symbiotically, they may alter not only soil nitrogen (N) conditions but also those of phosphorus (P). We studied the N-fixing shrub Dichrostachys cinerea in a mesic savanna in Zambia, quantifying its effects(More)

However, not all endophytes are beneficial to their hosts, but may instead be specialist enemies. Brachypodium sylvaticum is an invasive grass in the USA. In its European native range, it is nearly always infected by the(More)
