Vanonder het mos | Woekeren planten door verdubbeling erfelijk materiaal?

28 maart 2015 om 14:14 door Hans Baeté

De enorme impact die vreemde planten (exoten) kunnen hebben op inheemse populaties en ecosystemen onderstreept het belang van de zoektocht naar wat bepalend is voor dit woekerend, invasief gedrag (Vilà et al. 2010, 2011). Zoals alle bloemplanten moeten invasieve soorten goede kolonisten zijn om succes te hebben in nieuwe habitats. In het begin van de jaren 1980 groeide het idee dat planten die hun erfelijk materiaal verdubbelen hun territorium snel kunnen uitbreiden (Levin 1983).
