How far do invasive species travel?
Around the globe, an increasing number of plant and animal species are introduced into new regions through human activity. However, the global patterns of their distribution are only poorly understood to date. Researchers at the Senckenberg and at the universities of Oldenburg and Vienna have now discovered that the spread of species can be convincingly explained by a combination of global trade flows and the species' original distribution. And, contrary to previous assumptions, the spread basically follows very simple laws.
