Plant invasions as a challenge for science and practice : a view from the perspective of studies undertaken in Poland : [streszczenie]

Abstract

It is worthwhile emphasizing that biological invasion is currently one of the greatest global threats to nature. These circumstances have contributed to a significant increase in the interest of nature protection theoreticians and activists in this problem. Already in 1950s, Kornaś drew attention in the Polish scientific literature to the need for research on present-day migrations of plants which accompany humans (the so-called synanthropic species), also regarding the practical aspects of the necessity for controlling troublesome weeds (Fragment tekstu).
