    Sammanfattning : The increase in density and cover of woody plant species is coincident with the introduction of cattle in southern Africa, and it is a wide spread phenomenon in the savannas of the world. The causes are little understood, but can only be speculated to be either anthropogenic or natural or a combination of both. LÄS MER

  7. 5. Mass-spectrometry based survey of BMAA sources, distribution and transfer
