Neobiota. About migration of plants und animals.
Do you know the signal crayfish (= nordamerikanischen Signalkrebs - Pacifastacus leniusculus) or the Japanese knotweed (= Japanischen Staudenknöterich = Fallopia japonica)? Why does the crayfish aggrandize in the river Traun (Austria!), why does the Japanese knotweed grow exuberantly at the little lake of Pucking near Traun?
How many shrubs of elderberries exist in Saaremaa since....?

Maybe you have to ask your teacher affraid
