This paper deals with plant invasions in the Transcarpathian region of the Ukraine. Within Solidago genus, one native (S. virgaurea) and one invasive (S. canadensis) species were studied by measuring contents of phenolics and tannins. The results support the enemy release hypothesis. Because the invasive species can save its energy by aborting the phenolics production, and use this energy for other processes like growth or reproduction.
