Biological invasion is considered to be a major threat to biodiversity along with global climate change. Common milkweed (Asclepias syriaca L.) is a non-indigenous invasive plant species that has been invading large areas of sandy habitats in Hungary. This species hinders regeneration of sandy oldfields by inhibiting colonization and resource aquisition of natural species due to shading effects, high competitive capacity and allelopathic compounds.

Interactions between natural and human-dominated ecosystems: biodiversity, ecosystem functions and land-use in the Great Hungarian Plain
The Great Hungarian Plain is characterised by both unique natural values and intensive land-use. The on-going and future land-use changes may considerably affect ecological integrity, thus a further decline in biodiversity can only be avoided if nature conservation and socio-economic priorities are considered together. The overall objective of the proposed research is to assess the relationships between land-use, biodiversity and ecosystem functioning.
