Avaliação de impactos
1. Redução no desempenho de indivíduos da biota nativa
Resposta: Sim
Mecanismos selecionados: (1) Competição
Evidências por mecanismo
\"In both the field and in the pots, all three non-native plant groups had negative effects on P. lyonii reproductive potential, with Centaurea melitensis L. having the greatest effect. (...) In both the 2004 and 2005 field seasons, competition from all three groups of invasive species had significant negative impacts on P. lyonii inflorescence number (P , 0.01 in all cases, Fig. 1).\"

2. Declínio no tamanho populacional de espécie nativa
Resposta: Sim
Mecanismos selecionados: (6) Envenenamento / toxicidade
Evidências por mecanismo
\"In a study at Sugarloaf Rigde study in Sonoma County, California, total plant diversity increased significantly when yellow starthistle was controlled using multiple years of prescribed burning compared to unburned plots (DiTomaso et al. 1999a)\" (DiTomaso et al. 2006)
\"The final percentage of germination in H. aromaticum was significantly reduced ([80%) (F4,10 = 210.35; P \0.01) in the presence of dry and fresh leaves of C. melitensis from both origins, with no differences among them (Fig. 2). (...) The competitive impacts of C. melitensis on native species can occur by means of reducing plant growth, but also by inhibiting seed germination due to the potential allelopathic effects of the leaf lixiviates of C. melitensis\" (Sotes et al. 2021)
